This study investigated the effects of being born small for gestational age (SGA) on peripapillary retinal nerve fiber layer (pRNFL) thickness in adults born at term.Methods: A retrospective cohort study was conducted with a prospective ophthalmologic examination of participants born at full-term (gestational age ≥ 37 weeks) between 1969 and 2002. All participants were examined with spectral-domain optical coherence tomography and grouped according to their birth weight in correlation to gestational age as former moderate (birth weight (BW) percentile 3rd to < 10th) and severe SGA (< 3rd percentile), normal (10th-90th percentile, AGA), and moderately (> 90th to 97th percentile) and severely (> 97th percentile) large for gestational age (LGA) adults (18 to 52 years).Results: Overall, 547 eyes of 285 individuals (age 29.9± 9.4 years, 151 females) born at term were included. Multivariable regression analyses revealed a strong association between a lower global pRNFL thickness in the severe SGA (B=− 8.99 [95%-CI: − 12.68; − 5.30] μm; p< 0.001) and in the moderate SGA groups (B=− 6.40 [95%-CI: − 10.29; − 2.50] μm; p=0.001) compared to the reference AGA group.Conclusion: Our results indicate that restricted fetal growth affects neurologic tissue development of the optic nerve head, particularly in individuals born severely SGA at term. This indicates that fetal growth restriction may exert disturbances in the development of neurologic tissue, which persists in adulthood.Keywords: birth weight, small for gestational age, large for gestational age, peripapillary retinal nerve fiber layer, optic nerve head, epidemiology

Juliane Matlach,1 Sandra Bender,2 Jochem König,2 Harald Binder,2,3 Norbert Pfeiffer,1 Esther M Hoffmann1 1Department of Ophthalmology, University Medical Center Mainz, Mainz, Germany; 2Institute of Medical Biostatistics, Epidemiology and Informatics, University Medical Center Mainz, Mainz, Germany; 3Institute of Medical Biometry and Statistics, Medical Center – University of Freiburg, Freiburg, Germany Purpose: Since the role of short- and long-term intraocular pressure (IOP) fluctuation as a predictor of glaucoma progression is still controversial, the purpose of this study was to investigate the role of IOP fluctuation in a non-selected patient cohort. Materials and methods: Two-hundred and forty eyes of 120 glaucoma patients (51% female) with a mean age of 64.5 years were included. Inclusion criteria were at least a visual field (VF) and a 48-hour diurnal phasing of IOP including nocturnal measurement. Glaucoma progression was defined as – if available – confirmed progression of reproducible VF defects in at least three VF examinations or increase of cup area on optic nerve imaging (Heidelberg Retina Tomograph [HRT]) with at least two images after baseline. If results were stable or less than previously mentioned VF or HRT examinations were available, it was classified as “no progression”. Results: Glaucoma progression was seen in seven of 240 eyes in the VF analysis and ten of 240 eyes on HRT. Of all 240 eyes, 92 and 41 eyes fulfilled the criteria to be included for progression evaluation on VF and HRT analysis, respectively. Mean time to progression ± standard error was 3.6±0.2 years on VF and 4.5±0.3 years on HRT. Univariate and multivariate Cox regression analyses revealed short-term IOP fluctuation (P

Diffusion-based tractography in the optic nerve requires sampling strategies assisted by anatomical landmark information (regions of interest [ROIs]). We aimed to investigate the feasibility of expert-placed, high-resolution T1-weighted ROI-data transfer onto lower spatial resolution diffusion-weighted images. Slab volumes from 20 volunteers were acquired and preprocessed including distortion bias correction and artifact reduction. Constrained spherical deconvolution was used to generate a directional diffusion information grid (fibre orientation distribution-model [FOD]). Three neuroradiologists marked landmarks on both diffusion imaging variants and structural datasets. Structural ROI information (volumetric interpolated breath-hold sequence [VIBE]) was respectively registered (linear with 6/12 degrees of freedom [DOF]) onto single-shot EPI (ss-EPI) and readout-segmented EPI (rs-EPI) volumes, respectively. All eight ROI/FOD-combinations were compared in a targeted tractography task of the optic nerve pathway. Inter-rater reliability for placed ROIs among experts was highest in VIBE images (lower confidence interval 0.84 to 0.97, mean 0.91) and lower in both ss-EPI (0.61 to 0.95, mean 0.79) and rs-EPI (0.59 to 0.86, mean 0.70). Tractography success rate based on streamline selection performance was highest in VIBE-drawn ROIs registered (6-DOF) onto rs-EPI FOD (70.0% over 5%-threshold, capped to failed ratio 39/16) followed by both 12-DOF-registered (67.5%; 41/16) and nonregistered VIBE (67.5%; 40/23). On ss-EPI FOD, VIBE-ROI-datasets obtained fewer streamlines overall with each at 55.0% above 5%-threshold and with lower capped to failed ratio (6-DOF: 35/36; 12-DOF: 34/34, nonregistered 33/36). The combination of VIBE-placed ROIs (highest inter-rater reliability) with 6-DOF registration onto rs-EPI targets (best streamline selection performance) is most suitable for white matter template generation required in group studies., (© 2024 The Author(s).

Prcis: Bleb revision procedures for hypotony maculopathy (HM) following glaucoma filtering surgery show promising outcomes, including notable improvements in visual acuity and IOP., Purpose: This study assesses morphologic characteristics using SD-OCT in patients with HM following glaucoma filtering surgery and evaluates the results of its treatment., Materials and Methods: A retrospective analysis of all HM patients between January 2019 and March 2023. Inclusion criteria consisted of both preoperative and postrevision SD-OCT images of the macula and the presence of HM as observed on OCT images preoperatively. HM was graded according to its appearance in OCT both prerevision and postrevision surgery. Changes in visual acuity and IOP were assessed., Results: A total of 45 eyes of 45 patients were included. In all, 21 eyes had HM limited to retinal pigment epithelium (RPE), 18 eyes had involvement of RPE and photoreceptor layers, and 6 eyes had additional intraretinal or subretinal edema. After revision surgery with IOP elevation, 64% of eyes had complete HM regression with no HM signs in OCT imaging. Overall, 80% of patients achieved at least 1 grade improvement in HM. Preoperative visual acuity increased from 0.7±0.4 (logMAR) to 0.4±0.4 at 2 weeks postoperatively, over the course of an increase of IOP from 3.5±1.8 to 17.1±10.6 mm Hg at day 1. Eyes with complete HM regression had higher IOP at day 1 compared with those without improvement ( P =0.04). The median time between HM onset and revision was 10.0 days for those with complete regression and 27 days for those without improvement ( P =0.04)., Conclusions: Bleb revision procedures for HM following glaucoma filtering surgery show promising outcomes, including notable improvements in visual acuity and IOP. The timing of revision surgery appears to influence the outcome. In our study, earlier intervention was associated with better results. Even delayed surgeries can lead to an improvement, although complete morphologic restoration may not be achieved in advanced grades of HM., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: To investigate long-term astigmatism after combined nonpenetrating glaucoma surgery (NPGS) and implantation of the first miniaturized suprachoroidal intraocular pressure (IOP) sensor EYEMATE-SC., Setting: The study was conducted in 5 medical centers in 2 different countries., Design: Retrospective multicenter clinical study., Methods: Astigmatism of patients instrumented with the EYEMATE-SC IOP sensor was assessed over a follow-up period of 3 years. Refraction and corrected distance visual acuity (CDVA) were obtained preoperatively, after 6 months, 1, 2, and 3 years. A canaloplasty-operated patient cohort served as control. Astigmatism was evaluated using 3-dimensional power vector analysis involving the spherical equivalent M, and the Jackson crossed cylinder projections J 0 and J 45 . Exclusion criteria included neovascular and angle-closure glaucoma, myopia, axial length outside 22 to 26 mm, other ocular diseases, prior glaucoma surgery, other ocular surgery within 6 months (cataract surgery within 3 months) before NPGS, serious generalized conditions, and other active medical head/neck implants., Results: Multivariate analysis indicated no changes in astigmatism along the observation period in both the EYEMATE-SC (n = 24) and the canaloplasty (n = 24) group ( P > .05 or nonsignificant after Bonferroni correction). Astigmatism was unchanged between the EYEMATE-SC and the canaloplasty group at all timepoints ( P > .05). CDVA did not change along the observation period of 3 years in each of both groups ( P > .05)., Conclusions: Despite its suprachoroidal localization, this study indicated that the miniaturized EYEMATE-SC IOP sensor did not negatively affect long-term astigmatism after combined implantation with NPGS., (Copyright © 2024 Published by Wolters Kluwer on behalf of ASCRS and ESCRS.)

Topic: To identify patient-reported outcome measures (PROMs) that have been used in children and adolescents with glaucoma and to evaluate their methodologic quality., Clinical Relevance: Childhood glaucoma impairs vision and quality of life (QoL) throughout all stages of life. Thus, a PROM needs to cover many different age groups and topics. Various instruments have been used to evaluate patient-reported outcomes (PROs) in patients with childhood glaucoma, however, it is unclear which PROM has the highest methodologic quality and complies best with the needs of patients with childhood glaucoma., Methods: A systematic literature review was performed searching MEDLINE (PubMed), the Cochrane Library, Web of Science, and PsycINFO (EBSCO). We included peer-reviewed full-text articles of the past 10 years in English, German, or Spanish language that reported PROMs in children with glaucoma. The study selection and methodologic quality assessment of the identified PROMs was performed by 2 independent reviewers using a 7-point checklist. The content was mapped onto the World Health Organization International Classification of Functioning, Disability and Health. The systematic review was prospectively registered in PROSPERO (ID CRD42022353936)., Results: The search strategy retrieved 3295 matches. A total of 2901 studies were screened, and 11 relevant articles were identified using 10 different instruments. The instruments addressed functional visual ability, vision-related QoL, health-related QoL, and life satisfaction. Six instruments were applicable for the use in children. Seven of the questionnaires received the highest number of positive ratings (5/7). None of the instruments considered the views of patients with childhood glaucoma during their development., Conclusion: This systematic review provides a descriptive catalog of vision-specific and generic health PRO instruments that have been used in childhood glaucoma cohorts. An instrument specifically developed for childhood glaucoma is lacking which might result in missing important factors, such as permanent treatment with eye drops, repeated surgeries, and heritability of the disease, when investigating the QoL in children with glaucoma., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Purpose: In recent years artificial intelligence (AI), as a new segment of computer science, has also become increasingly more important in medicine. The aim of this project was to investigate whether the current version of ChatGPT (ChatGPT 4.0) is able to answer open questions that could be asked in the context of a German board examination in ophthalmology., Methods: After excluding image-based questions, 10 questions from 15 different chapters/topics were selected from the textbook 1000 questions in ophthalmology (1000 Fragen Augenheilkunde 2nd edition, 2014). ChatGPT was instructed by means of a so-called prompt to assume the role of a board certified ophthalmologist and to concentrate on the essentials when answering. A human expert with considerable expertise in the respective topic, evaluated the answers regarding their correctness, relevance and internal coherence. Additionally, the overall performance was rated by school grades and assessed whether the answers would have been sufficient to pass the ophthalmology board examination., Results: The ChatGPT would have passed the board examination in 12 out of 15 topics. The overall performance, however, was limited with only 53.3% completely correct answers. While the correctness of the results in the different topics was highly variable (uveitis and lens/cataract 100%; optics and refraction 20%), the answers always had a high thematic fit (70%) and internal coherence (71%)., Conclusion: The fact that ChatGPT 4.0 would have passed the specialist examination in 12 out of 15 topics is remarkable considering the fact that this AI was not specifically trained for medical questions; however, there is a considerable performance variability between the topics, with some serious shortcomings that currently rule out its safe use in clinical practice., (© 2024.

Purpose: This study explores associations between fetal growth restriction or excessive fetal growth, along with perinatal factors on the optic nerve head morphology in adulthood., Design: Retrospective cohort study., Methods: This retrospective cohort study involved a prospective ophthalmological examination of individuals born at full term (with a gestational age of ≥37 weeks) from 1969 to 2002. Each participant underwent nonmydriatic fundus camera photography to capture images of the optic discs, followed by manual measurements. The vertical cup-to-disc ratio (VCDR) and optic disc area were examined and analyzed in relation to the baby's birth weight relative to the gestational age. These categories included those with former moderate (birth weight percentile between the 3rd and <10th), severe SGA (below the third percentile), normal (AGA, 10th-90th percentile), and moderately (birth weight >90th-97th percentile) and severely (birth weight >97th percentile) large for gestational age (LGA) adults within the age range of 18 to 52 years., Results: Overall, 535 eyes of 280 individuals (age 29.7 ± 9.2 years, 144 females) born at full term were included. Multivariable analysis showed a significant association between a larger VCDR and the severe SGA group (B = 0.05, 95% CI 0.01-0.10; P = .02). In the univariable model, placental insufficiency was associated with VCDR (B = 0.10, 95% CI 0.01-0.19; P = .03). Other perinatal factors did not demonstrate an association with VCDR. Furthermore, there was an indication of an association suggesting a smaller optic disc area in individuals born moderately SGA at full term (B = -0.17, 95% CI -0.33 to -0.001; P = .05)., Conclusions: This study provides evidence that individuals born at-term with severe SGA have an increased VCDR, suggesting that fetal growth restriction has a lasting impact on optic disc morphology independent of prematurity throughout adulthood., (Copyright © 2024 The Authors.

Background : The aim of this study was to evaluate the short-term efficacy and safety of the Paul Glaucoma Implant (PGI) in pediatric eyes diagnosed with glaucoma following congenital cataract surgery (GFCS). Methods : A retrospective, single-center, descriptive study was conducted on consecutive children diagnosed with GFCS who underwent PGI implantation between July 2022 and November 2023 at the University Medical Center Mainz. The primary outcome measure was the reduction in IOP at the last follow-up visit. Results : Ten eyes of nine children were included in the study. The mean follow-up time was 7.70 ± 4.22 months (4.68-10.72 months). At the end of the study follow-up, the mean (95% CI) reduction in IOP was -14.8 ± 8.73 mmHg (-8.56 to -21.04 mmHg, p < 0.001). At the last follow-up, 30.0% (3/10) of patients achieved an IOP (intraocular pressure) of ≥6 and ≤21 mmHg with a reduction in IOP of ≥25% without treatment, while 90.0% (9/10) achieved this target IOP regardless of glaucoma medication treatment. The mean number of antiglaucoma medications was significantly reduced from 3.50 (IQR = 1) to 2.0 (IQR = 2, p = 0.01), and the visual acuity logMAR improved from 1.26 ± 0.62 to 1.03 ± 0.48 ( p = 0.04). Only one eye experienced numerical hypotony (4 mmHg) without choroidal detachment or anterior chamber shallowing within the first 24 h. No other adverse events were observed during the follow-up period. Conclusions : PGI implantation significantly lowered IOP and the number of antiglaucoma eye drops with a favorable safety profile in children diagnosed with GFCS, thereby achieving a high rate of qualified surgical success in the short term.

Primary open-angle glaucoma is a neurodegenerative disease with progressive chronic optic neuropathy and corresponding visual field defects. In this literature review, we discuss systemic diseases and their mechanism for developing glaucoma, including systemic hypertension and hypotension, diabetes, dyslipidemia, obstructive sleep apnoea syndrome, chronic kidney disease, migraine, and polypharmacy., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht./The authors declare that they have no conflict of interest., (Thieme.

Purpose: To investigate the longitudinal change in intraocular pressure (IOP) over 5 years and its relationship with cardiovascular parameters in a population-based sample in Germany., Methods: The Gutenberg Health Study is a prospective, observational, single-center cohort study. The sample was equally stratified for sex, residence, and age decade. IOP was measured with noncontact tonometry at baseline and at 5-year follow-up. Cardiovascular parameters, including body mass index (BMI), systolic blood pressure, and diabetes status, were assessed. Participants without IOP measurement at one time point, who were taking IOP-lowering medications, or who had ophthalmic surgery during the 5-year follow-up interval were excluded, as well as those with glaucoma diagnosis. Univariable and multivariable linear regression analyses were conducted., Results: This analysis included 9633 participants (48.9% female). The mean IOP increased from 14.04 ± 2.78 mmHg at baseline to 14.77 ± 2.92 mmHg at 5-year follow-up (P < 0.001). In multivariable linear regression analyses, an increase in BMI was associated with an increase in IOP over time (P < 0.001), whereas a higher baseline BMI was associated with a lower IOP change (P < 0.001). Higher age and male sex were associated with higher IOP change (P < 0.001). A change in systolic blood pressure was associated with IOP change, whereas baseline systolic blood pressure and diabetes status were not associated., Conclusions: This population-based study found a relationship between IOP change over 5 years and BMI and systolic blood pressure change, respectively. These findings suggest the importance of monitoring cardiovascular risk factors in IOP management.

Background: Glaucoma is not a rare entity but because very few symptoms occur and visual field defects are frequently first recognized at a late stage, a large proportion of glaucoma diseases remain undetected. The aim of this study was to identify the proportion of undiagnosed glaucoma in German population-based cohort studies and to contextualize them in the context of the literature., Material and Methods: The prevalence of glaucoma in the Gutenberg Health Study (GHS) and the age-related investigations on health of the University of Regensburg (AugUR) was evaluated based on visual field examinations and optic disc color photography according to the ISGEO criteria. Furthermore, the self-reported glaucoma diagnoses were collected and the proportion of undiagnosed glaucoma was determined., Results: The proportion of undiagnosed glaucoma was 55% in the GHS, and 53% in the AugUR study. The results correlate with results from previous studies from other countries in which the proportion of unrecognized glaucoma ranged from 33% to 78%. In the GHS and the AugUR study the proportion of undiagnosed glaucoma was higher in younger age groups and in women., Discussion: Roughly every second case of glaucoma is undetected. As the symptoms are often nonspecific or take a long time to appear, there is a risk of advanced glaucomatous visual field defects or blindness due to a lack of glaucoma awareness. Studies have shown that a systematic screening can halve this risk., (© 2023. The Author(s), under exclusive licence to Springer Medizin Verlag GmbH, ein Teil von Springer Nature.)

This article provides an overview of real-world outcomes in glaucoma surgical procedures. While randomized clinical trials provide valuable insights, they do not fully reflect real-world clinical practice. Real-world studies enable the evaluation of outcomes in uncontrolled settings and play a crucial role in counselling and decision-making for glaucoma treatment. By examining real-world data the article aims to identify rare adverse events that may go unnoticed in controlled clinical trials. The focus is on assessing the effectiveness and safety of glaucoma surgical procedures beyond the controlled trial setting., (© 2023.

Background: Point-of-care Ocular Ultrasound (POCOUS) has gained importance in emergency medicine and intensive care in recent years. This work aimed to establish and evaluate a dedicated ultrasound education program for learning POCOUS-specific skills during medical studies at a university hospital., Methods: The blended learning-based program (6 teaching units) based on recent scientific publications and recommendations was developed for students in the clinical part of their medical studies. Experts and trainers consisted of physicians from the Ear-Nose-Throat, radiology, ophthalmology and neurology specialties as well as university educational specialists. Lecture notes containing digital video links for preparation was produced as teaching material. In total, 33 students participated in the study. The education program, including the teaching materials, motivation and subjective gain in competency, was evaluated with the aid of a questionnaire (7-point Likert response format). Objective learning success was assessed on the basis of pre- and post-tests. These covered the skill areas: "anatomical basics", "ultrasound basics", "understanding of cross-sectional images", "normal findings" and "pathology recognition"., Results: In the objective assessment of image interpretation, the participants improved significantly (p < 0.001) from pre- to post-test with a large effect size (Cohen's d = 1.78, effect size r = 0.66). The evaluations revealed a high level of satisfaction with the course concept, teaching materials and the tutors. In addition, a high level of motivation was recorded in relation to continuing to study "ultrasound diagnostics" and "ophthalmologic diseases". A significant (p < 0.01) positive gain was also achieved in terms of the subjective assessment of competency. This covers areas such as expertise, sonographic anatomy and performing a POCOUS examination as well as recognizing retinal detachment, globe perforation and increased optic nerve sheath diameter., Conclusion: The results of this feasibility study show that medical students accept and support a POCOUS-specific education program and are able to develop a higher objective and subjective level of competency. Future transfer to other sites and larger groups of participants seems feasible., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Prcis: After the open bleb revision following PreserFlo, the mean postoperative intraocular pressure (IOP) was lowered from 26.4 ± 9.9 mm Hg to 12.9 ± 5.6 mm Hg at 1 month and 15.9 ± 4.1 mm Hg at 12 months., Purpose: The purpose of this study was to evaluate the effectiveness and safety of an open bleb revision with mitomycin- C (MMC) for bleb fibrosis after PreserFlo MicroShunt implantation., Patients and Methods: We performed a retrospective analysis of 27 consecutive patients with bleb fibrosis after PreserFlo MicroShunt Implantation that underwent an open revision with MMC 0.2 mg/mL applied for 3 minutes at the Department of Ophthalmology of the Mainz, University Medical Center, Mainz, Germany. Demographic data, such as age, sex, glaucoma type, number of glaucoma medications, IOP before and after PreserFlo implantation and revision, complications, and reoperations within 12 months, were analyzed., Results: Twenty-seven patients (27 eyes) received an open revision after previous PreserFlo Microshunt implantation and consecutive bleb fibrosis. The mean preoperative IOP was 26.4 ± 9.9 mm Hg before revision, 7.0 ± 2.7 mm Hg ( P < 0.001) in the first week after the revision, and 15.9 ± 4.1 mm Hg at 12 months ( P = 0.02). Four patients needed IOP-lowering medication after 12 months. One patient had a positive Seidel test and needed a conjunctival suture. Four patients required a second procedure due to recurring bleb fibrosis., Conclusions: At 12 months, open revision with MMC for bleb fibrosis after failed PreserFlo implantation effectively and safely reduced IOP with a similar medication burden., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2023 The Author(s).

Purpose: To assess long-time results of primary surgical treatment in children with glaucoma after congenital cataract surgery., Methods: A retrospective study of 37 eyes from 35 children with glaucoma after congenital cataract surgery, who underwent surgery between 2011 and 2021 at the Childhood Glaucoma Center, University Medical Center Mainz, Germany. Only children, who received a primary glaucoma surgery in our clinic within the given time (n = 25) and had at least one-year follow-up (n = 21), were included in the further analysis. The mean follow-up time was 40.4±35.1 months. The primary outcome was the mean reduction in IOP (in mmHg) from baseline to follow-up visits after the surgery, measured with Perkins tonometry., Results: 8 patients (38%) were treated with probe trabeculotomy (probe TO), 6 (29%) with 360° catheter-assisted trabeculotomy (360° TO) and 7 (33%) with cyclodestructive procedures. IOP was significantly reduced after probe TO and 360° TO after 2 years, from 26.9 mmHg to 17.4 mmHg (p<0.01) and 25.2 mmHg to 14.1 mmHg (p<0.02), respectively. There was no significant IOP reduction after cyclodestructive procedures after 2 years. Both, probe TO and 360° TO led descriptively to eye drops reduction after 2 years, from 2.0 to 0.7 and 3.2 to 1.1. The reduction was not significant., Conclusions: In glaucoma after congenital cataract surgery, both trabeculotomy techniques, lead to good reduction of IOP after 2 years. There is a need for a prospective study with comparison to the use of glaucoma drainage implants., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Strzalkowska et al.

Purpose: To investigate the association between intraocular pressure (IOP) and climate parameters., Methods: The Gutenberg Health Study (GHS) is a population-based cohort study in Mainz, Germany. Participants underwent two comprehensive ophthalmologic examinations (baseline visit and five-year follow up) including non-contact tonometry, objective refraction, pachymetry, perimetry, and fundus imaging in the time frame of 2007 to 2017. The respective climate parameters were assessed at the University Mainz including temperature, air humidity, and air pressure. Associations of IOP and climatic parameters were computed using component models and cross-correlation plots. Multivariable regression analysis was performed to adjust for age, sex, body mass index, diabetes, central corneal thickness, and systolic blood pressure. To further explore the link between systolic blood pressure, temperature, and IOP, an effect mediation analysis was conducted., Results: A total of 14,632 participants (age 55 ± 11 years at baseline, 49.1% female) were included in this analysis. Mean IOP was 14.24 ± 2.8 mm Hg at baseline. There was a similar periodic change in IOP and in temperature, as shown in the component models. IOP was not associated with air humidity. In univariable and multivariable regression analyses we found a significant association between lower IOP during the summer months with higher air temperature (B = -0.011, P < 0.001). This could be partially explained in mediation analysis by lower systolic blood pressure at higher air temperature. Furthermore, IOP was associated with air pressure in univariable (B = 0.005, P = 0.04.) and multivariable models (B = 0.006, P = 0.03)., Conclusions: There is a periodic annual change of IOP with higher values in winter and lower values in summer supporting the hypothesis of an impact of environmental temperature on IOP, which is partly mediated by lower systolic blood pressure in summer.

Along with climate change, population growth, and overexploitation of natural resources, urbanisation is among the major global challenges of our time. It is a nexus where many of the world's grand challenges intersect, and thus key to sustainable development. The widespread understanding of urbanisation as a successive and unidirectional transformation of landscapes and societies from a rural to an urban state is increasingly questioned. Examples from around the globe show that 'the rural' and 'the urban' are not only highly interdependent, but actually coexist and often merge in the same space or livelihood strategy. Our concept of rurbanity provides an integrated theoretical framework which overcomes the rural-urban divide and can be operationalised for empirical research. Rurbanity is the next stringent step following the gradual widening of previous concepts from urban-centred approaches through the emphasis on urban peripheries to attempts of abolishing any distinction of a rural environment and acknowledging the highly dynamic nature of globalising urbanisation. Building on complex systems theory and assemblage thinking, our concept explores complementary aspects of the distinct epistemic worldviews dominating the natural and social sciences. Within this theoretical frame, we derive four analytical dimensions as entry points for empirical research: Endowments and Place , Flows and Connectivity , Institutions and Behaviour , and Lifestyles and Livelihoods . Two examples illustrate how these dimensions apply, interact, and together lead to a comprehensive, insightful understanding of rurban phenomena. Such understanding can be an effective starting point for assessing potential contributions of rurbanity to long-term global sustainability., (© The Author(s) 2023.)

Aim: To investigate the safety and performance of a telemetric suprachoroidal intraocular pressure (IOP) sensor (EYEMATE-SC) and the accuracy of its IOP measurements in open angle glaucoma (OAG) patients undergoing simultaneous non-penetrating glaucoma surgery (NPGS)., Methods: Prospective, multicentre, open-label, single-arm, interventional clinical trial. Twenty-four eyes of 24 patients with OAG regularly scheduled for NPGS (canaloplasty or deep sclerectomy) were simultaneously implanted with an EYEMATE-SC sensor. Six-month follow-up on the sensor's safety and performance as well as on the level of agreement between the EYEMATE-SC measurements and IOP measurements with Goldmann applanation tonometry (GAT)., Results: The eyes underwent canaloplasty (n=15) or deep sclerectomy (n=9) and achieved successful implantation of the sensor. No device migration, dislocation or serious device-related complications occurred. A total of 367 comparisons were included in the IOP agreement analysis. The overall mean difference between GAT and EYEMATE-SC measurements was 1.31 mm Hg (lower limit of agreement (LoA) 7.55 mm Hg; upper LoA -4.92 mm Hg). The maximum difference of 2.5 mm Hg ±3.96 (LoA 0.30-2.29) was reached on day 10 and continuously improved to an agreement of -0.15 mm Hg ±2.28 (LoA -1.24 to 0.89) after 6 months. Accordingly, the percentage of eyes within an IOP difference of ±5 mm Hg improved from 78% (day 3) to 100% (6 months)., Conclusions: After 6 months, the EYEMATE-SC sensor was safe and well tolerated, and allowed continual IOP monitoring., Trial Registration Number: NCT03756662., Competing Interests: Competing interests: PS has a pending international patent for the EYEMATE-SC system (PCT/EP2015/062976).

Purpose: Measuring and controlling intraocular pressure (IOP) provide the foundation for glaucoma treatment. Self-tonometry has been proposed as an alternative to measure IOP throughout the entire day better. The novel EYEMATE-SC sensor (Implandata) is implanted in the suprachoroidal space to enable contactless continual IOP monitoring. The aim of the present study was to investigate the 1-year safety, performance, and accuracy of the EYEMATE-SC in patients with primary open-angle glaucoma undergoing simultaneous nonpenetrating glaucoma surgery (NPGS)., Design: Prospective, multicenter, open-label, single-arm, interventional clinical trial., Participants: Twenty-four eyes of 24 patients with primary open-angle glaucoma who were due to undergo NPGS (canaloplasty or deep sclerectomy)., Methods: An EYEMATE-SC sensor was implanted during NPGS. Goldmann applanation tonometry (GAT) measurements were compared with the sensors' IOP measurements at all postoperative visits through 12 months., Main Outcome Measures: Device position and adverse events., Results: Fifteen eyes underwent canaloplasty, and 9 underwent deep sclerectomy. Successful implantation of the sensor was achieved in all eyes with no reported intraoperative difficulties. Through the 12-month follow-up, no device migration, dislocation, or serious device-related complications were recorded. A total of 536 EYEMATE-SC measurements were pairwise included in the IOP agreement analysis. The overall mean difference between GAT and EYEMATE-SC measurements was 0.8 mmHg (95% confidence interval [CI] of the limits of agreement [LoA], -5.1 to 6.7 mmHg). The agreement gradually improved, and from 3 months after surgery until the end of the follow-up, the mean difference was -0.2 mmHg (95% CI of LoA, -4.6 to 4.2 mmHg) over a total of 264 EYEMATE-SC measurements, and 100% of measurements were within ±5 mmHg of GAT., Conclusions: The EYEMATE-SC sensor was safe and well tolerated through 12 months. Moreover, it allowed accurate, continuous IOP monitoring., Financial Disclosure(s): Proprietary or commercial disclosure may be found after the references., (Copyright © 2022.

Glaucoma in infancy and childhood is a rare disease. An immediate diagnosis and treatment are absolutely necessary to prevent blindness of affected children. Childhood glaucoma is characterized by a heterogeneous phenotype: besides primary congenital glaucoma, secondary types often exist and the individualized treatment requires an experienced interdisciplinary team. The pathogenesis is not always discernible and genetic alterations sometimes cause the disease. A surgical procedure is usually necessary to lower the intraocular pressure. Refractive and orthoptic care are equally important to avoid amblyopia. This article gives an overview of childhood glaucoma and outlines the most important diagnostic and therapeutic aspects., (© 2023.

Background: To evaluate the long-term efficacy and safety of modified canaloplasty versus trabeculectomy in open-angle glaucoma., Methods: In total, 210 subjects with open-angle glaucoma were included. 70 were treated with Mitomycin C-augmented modified canaloplasty with enhanced subconjunctival filtration and 140 with Mitomycin C-augmented trabeculectomy. Cases were matched 1:2 by sex and age., Results: In canaloplasty and trabeculectomy groups, 61.4% and 57.9% of participants were female. Mean age was 60.0 ± 13.9 and 63.0 ± 12.2 years, median follow-up time was 4.6 [IQR 4.3, 5.05] years and 5.8 [IQR 5.4, 6.3]. Strict success was achieved in 20.0% and 56.4%, complete success in 24.3% and 66.4%, and qualified success in 34.3% and 73.6% (each p < 0.001). Kaplan-Meier survival analysis showed a better survival probability for trabeculectomy than for canaloplasty ( p < 0.001) and Cox regression analysis revealed an HR of 6.03 (95%-CI 3.66, 9.93, p < 0.001) after canaloplasty. Trabeculectomy showed superiority in terms of IOP decrease (9.2 ± 7.9 mmHg vs. 13.7 ± 10.4 mmHg, p = 0.002), use of AGM (50.0% vs. 10.7%, p < 0.001), and the number of revision surgeries (41.4% vs. 21.4%, p = 0.004). Occurrence of complications was similar in both groups (14.5% vs. 7.5%, p = 0.19)., Conclusions: Trabeculectomy showed superiority in efficacy and equality in safety compared to modified canaloplasty.

Objective: To evaluate the long-term outcomes of trabeculectomy (TE) surgery in a large cohort with a minimum follow-up of 3 years., Design: Retrospective cohort study., Setting: University Eye Hospital, Germany., Participants: Three hundred and seventy-nine patients with open-angle glaucoma underwent TE with mitomycin C (MMC) between January 2013 and February 2017 with a minimal follow-up of 3 years. Eligible patients were identified via an electronic surgical case register., Interventions: All patients had undergone TE with MMC following a set surgical protocol. To assess the influence of cataract surgery following TE, eyes which underwent cataract surgery at least 6 months after TE were matched 1:3 by sex and age to eyes who did not undergo cataract surgery during the follow-up period., Main Outcome Measures: Primary outcome was the proportion of surgical success based on intraocular pressure (IOP), surgical complications, the need for revision surgery, loss of light perception and the need for additional pressure-lowering medication., Results: The mean follow-up time was 6 (±0.8, IQR: 5.4-6.5) years. Seventy-three per cent of eyes achieved qualified surgical success at the last follow-up (IOP≥5 mm Hg and ≤18 mm Hg, without surgical complications or complete loss of vision) but necessitated additional medical therapy, complete surgical success with no additional medical therapy was achieved in 69% of eyes. There was no significant difference in the success probability between eyes that had undergone cataract surgery after TE and those that had not (p=0.45)., Conclusions: The results demonstrate a high and stable success rate of TE after a mean follow-up time of approximately 6 years, that is, not affected by later cataract surgery., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Purpose: This study investigated whether prematurity and associated factors or prenatal growth restriction have long-term effects on the peripapillary retinal nerve fiber layer (pRNFL) in adulthood., Design: Retrospective cohort study., Methods: The Gutenberg Prematurity Eye Study (GPES) is a retrospective cohort study with a prospective ophthalmologic examination in Germany. Selected individuals born term and preterm (age 18-52 years) were examined with spectral-domain optical coherence tomography (SD-OCT) in adulthood, and perinatal medical charts were reviewed. The pRNFL thickness was measured using SD-OCT. Univariate and multivariable linear regression analyses were conducted to investigate associations between pRNFL and gestational age (GA; categorical), birth weight percentile (categorical), retinopathy of prematurity (ROP) occurrence, and treatment and other perinatal parameters with adjustment for age, sex, and spherical equivalent., Results: In total, 766 eyes of 406 preterm and full-term individuals were included (mean age 28.4 ± 8.6 years, 228 females). After adjustment for age, sex, and spherical equivalent, global pRNFL thinning was associated with moderate (GA = 33-36 wk, β = -4.68, P < .001), very (GA = 29-32 wk, β = -5.72, P < .001), and extreme (GA ≤ 28 wk, β = -8.69, P < .001) prematurity but not with low birth weight percentile (<25th percentile, P = .9) and ROP occurrence (P = .9) in multivariable analysis. ROP treatment was associated with increased pRNFL in the temporal sector (P = .002). Maternal smoking during pregnancy showed an association with pRNFL thinning (P = .07)., Conclusion: Our data indicate that the more preterm individuals are born the more pRNFL thinning occurs, whereas prenatal growth restriction and postnatal occurrence of ROP show less effects on pRNFL thickness. Furthermore, individuals with severe ROP with treatment but not lower ROP stages without treatment showed an increased temporal pRNFL thickness., (Copyright © 2022 Elsevier Inc.

Trabeculectomy represents the glaucoma surgical procedure that achieves the greatest reduction in intraocular pressure and enables a low pressure regulation especially in normal pressure glaucoma. For the beginner the operation is challenging due to potential intraoperative and postoperative difficulties. With this in mind this article explains how to learn to perform a trabeculectomy and explains the various steps from assessing the indications via training, performing the surgery independently and follow-up care. The article points out the challenges during the procedure and the possible solutions and explains the individual aftercare using the Mainz treatment scheme as an example. In this way, the risk of serious complications can be reduced to a minimum and in the vast majority of patients a sufficient regulation of intraocular pressure can be achieved without the need for eye drops., (© 2022.

Background: Trabeculectomy (TE) remains one of the most frequently performed glaucoma procedures. This surgery enables sufficient reduction of intraocular pressure (IOP) and freedom from using eye drops; however, complication management and time-consuming postoperative care make many ophthalmic surgeons reluctant to include TE in their treatment regimen., Aim: This review presents the value of TE compared to other forms of filtering and nonfiltering glaucoma surgery., Conclusion: The use of TE is still the most effective method for lowering IOP and in comparison to other forms of glaucoma surgery in most cases enables freedom from eye drops with a subsequent high quality of life. Postoperative complications occur more frequently, but usually heal spontaneously or can be treated adequately and safely by surgery; however, TE requires intensive postoperative care, which should not be neglected. Repeated surgery due to insufficient IOP reduction is less frequent compared to other forms of glaucoma surgery., (© 2022.

Purpose: To assess surgical success and the post-operative development of intraocular pressure between XEN45 ® gelstent, Preserflo ® MicroShunt and trabeculectomy with mitomycin C., Methods: Data from 105 eyes from 105 patients of matched cases with refractory open-angle glaucoma, who underwent surgery between January 2019, and August 2020, were evaluated. Patients underwent either stand-alone XEN gelstent insertion with Mitomycin C, stand-alone Preserflo with Mitomycin C or trabeculectomy with Mitomycin C. The primary outcome was the proportion of complete surgical success at 6 months post-operatively (i.e. intraocular pressure between 5mmHg and 18mmHg, no revision surgery, no loss of light perception and no post-operative pharmaceutical antiglaucomatous treatment). The reduction of intraocular pressure after 6 months, the classes of antiglaucomatous medication used post-operatively, best-corrected visual acuity, spherical refractive errors and astigmatism were assessed as secondary outcomes., Results: We included 35 eyes in each group. After 6-month follow-up, complete success was 73.5% [95%-CI: 57.9%-89.2%] in the trabeculectomy group, 51.4% [95%-CI: 34.0%-68.8%] in the XEN group and 74.2% [95%-CI: 57.9%-90.5%] in the Preserflo group (p = 0.08). Regarding secondary outcomes, the reduction of intraocular pressure was 12.1 ± 7.9 mmHg in the trabeculectomy group and was thereby 5.8 [95%-CI: 2.2-9.6] mmHg greater compared with the XEN group (p < 0.001) and 4.8 [95%-CI: 0.9-8.7] mmHg higher than the Preserflo group (p = 0.01)., Conclusions: No statistically significant differences were found between trabeculectomy, XEN45 ® gelstent implantation and Preserflo ® MicroShunt implantation regarding surgical success after 6 months. Yet reduction in intraocular pressure was significantly higher in the trabeculectomy group. However, all three interventions resulted in sufficiently low post-operative intraocular pressure and may therefore be considered individually for glaucoma treatment., (© 2021 The Authors.

Purpose: This study aimed to investigate associations of prematurity and associated factors with optic disc morphology in adulthood as long-term effects., Design: Retrospective cohort study., Methods: The Gutenberg Prematurity Eye Study (GPES) is a retrospective cohort study with a prospective ophthalmologic examination of adults (age 18-52 years) in Germany. In every participant, photography of optic discs was performed with a nonmydriatic fundus camera, and optic disc measurements were done manually. The vertical cup-to-disc ratio (VCDR), optic disc area, and torted and tilted discs were assessed and exploratively compared between individuals with retinopathy of prematurity (ROP) with treatment, an ROP group without treatment and groups of individuals of different gestational ages (GAs) without ROP (GA ≤ 28 weeks, GA 29-32 weeks, GA 33-36 weeks, and GA ≥ 37 weeks [control group])., Results: The present analysis included 743 eyes of 393 individuals born preterm and full-term (aged 28.4 ± 8.6 years, 223 females). The VCDR was significantly larger in subjects with a GA ≤28 weeks without ROP compared to the full-term control group (GA ≥37 weeks) (P = .002). Subjects with ROP without treatment also had a larger VCDR (P = .001), whereas those with ROP treatment showed a smaller VCDR than the full-term control group (P = .02). In addition, individuals with ROP treatment were more likely to have a torted disc than the full-term control group (P = .006)., Conclusion: The present study provides evidence that individuals born extremely preterm have increased VCDR in adulthood. Furthermore, these results indicate that fetal origins affect optic disc morphology until adulthood, which might predispose the affected individual to degenerative optic nerve head diseases or being incorrectly diagnosed to glaucoma., (Copyright © 2022 Elsevier Inc.

Childhood glaucoma is a rare disease. Since a lacking therapy normally leads to blindness an immediate diagnosis and appropriate treatment are crucial. The heterogeneity of childhood glaucoma requires a comprehensive knowledge of possible underlying pathomechanisms of primary and secondary childhood glaucoma types. Several types of childhood glaucoma are accompanied with ocular or systemic syndromes and hereditary causes are frequent. Thus, an interdisciplinary team of ophthalmologists, orthoptists, pediatricians, human geneticists, and anesthesiologists is vital for a successful supply. Most cases rely on a dysgenesis of trabecular meshwork with impaired outflow. Thus, usually a surgical approach is indicated. To handle a surgery in a buphthalmic eye an experienced hand is required. Special attention should be paid on the correct prescription of topical antiglaucomatous therapy in children since they are more prone to develop side effects. This article aims to provide an overview about the different childhood glaucoma types and to point out the most important aspects of their individual treatment strategies., Competing Interests: Erklärung zu finanziellen Interessen Forschungsförderung erhalten: ja, von einer anderen Institution (Pharma- oder Medizintechnikfirma usw.); Honorar/geldwerten Vorteil für Referententätigkeit erhalten: nein; Bezahlter Berater/interner Schulungsreferent/Gehaltsempfänger: nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an im Bereich der Medizin aktiven Firma: nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an zu Sponsoren dieser Fortbildung bzw. durch die Fortbildung in ihren Geschäftsinteressen berührten Firma: nein.

Background: The corona pandemic has had a significant impact on the conditions of university student teaching. Due to the pandemic-related contact restrictions, digital teaching formats were widely used instead of the previous face-to-face teaching. In the summer semester of 2020 students received this well and evaluated it positively in recent publications. In this work, the main focus was on the experiences and assessments of teachers in ophthalmology during the winter semester 2020/2021., Methods: By means of two anonymous surveys via online questionnaires, the lecturers in ophthalmology of German university hospitals as well as internal and external lecturers and staff members of the student teaching of the Department of Ophthalmology of the University Medical Center Mainz were asked about their experiences with the implementation of digital teaching., Results: In this context 95% of the teaching staff of ophthalmology departments of university hospitals in Germany stated that they had established digital teaching concepts at the latest since the corona pandemic. Hybrid formats with a proportion of face-to-face teaching were used by 68%. A wide variety of teaching formats were used. Difficulties were also encountered, particularly in interaction with students. Despite predominantly digital teaching, examinations continued to be held in face-to-face settings; only 18% of respondents stated that they had conducted online examinations. In the future, 86% of respondents want to integrate digital formats into their teaching concepts and establish them as a supplement to existing face-to-face teaching., Conclusion: The development of student teaching during the corona pandemic can serve as an opportunity for shaping the future education of medical students in ophthalmology., (© 2021.

Objective: We aimed to compare intraocular pressure (IOP) measurements using iCare® PRO rebound tonometry (iCare) and Perkins applanation tonometry (Perkins) in childhood glaucoma subjects and healthy children and the influence of anaesthesia depth, age and corneal thickness. Material: Prospective clinical, case-control study of children who underwent an ophthalmologic examination under general anaesthesia according to our protocol. Children were 45.45 ± 29.76 months old (mean ± SD (standard deviation)). Of all children, 54.05% were female. IOP was taken three times (T1−T3), according to duration and the depth of anaesthesia. The order of measurement alternated, starting with iCare. Agreement between the device measurements was evaluated using Bland−Altman analysis. Results: 53 glaucoma subjects and 22 healthy controls. Glaucoma subjects: IOP measured with iCare was at T1: 27.2 (18.1−33.8), T2: 21.6 (14.8−30.6), T3: 20.4 mmHg (14.5−27.0) and Perkins 17.5 (12.0−23.0), 15.5 (10.5−20.5), 15.0 mmHg (10.5−21.0) (median ± IQR (interquartile range)). Healthy controls: IOP with iCare: T1: 13.3 (11.1−17.0), T2: 10.6 (8.1−12.4), T3: 9.6 mmHg (7.7−11.7) and Perkins 10.3 (8.0−12.0), 7.0 (5.5−10.5), 7.0 mmHg (5.5−8.5) (median ± IQR). The median IOP was statistically significantly higher with iCare than with Perkins (p < 0.001) in both groups. The mean difference (iCare and Perkins) was 6.0 ± 6.1 mmHg for T1−T3, 7.3 at T1, 6.0 at T2, 4.9 mmHg at T3. Conclusion: The IOP was the highest in glaucoma subjects and healthy children at T1 (under sedation), independently of the measurement method. iCare always leads to higher IOP compared to Perkins in glaucoma and healthy subjects, regardless of the duration of anesthesia.

Purpose: To evaluate long-term results of glaucoma surgery in newborn and infants with glaucoma., Methods: Seventy-nine eyes of 52 children (age: 3 weeks-15.3 years) with primary congenital or secondary glaucoma treated between 2015 and 2017 were included. The median follow-up time was 3.9 years. Conventional probe trabeculotomy, 360° catheter-assisted trabeculotomy, filtering and cyclodestructive surgery were compared. Strict criteria for surgical success were applied: Complete surgical success (IOP below target IOP, no further surgery) and incomplete surgical success (additional surgery allowed) were analyzed, and IOP at baseline and last follow-up was compared., Results: Intraocular pressure (IOP) was significantly reduced in primary congenital (preoperative IOP: 27.8 ± 7.5 mmHg vs. postoperative IOP: 14.2 ± 4.5 mmHg) and secondary glaucoma (preoperative IOP: 29.2 ± 9.1 mmHg vs. postoperative IOP: 16.6 ± 4.7 mmHg). 90% of all eyes reached target IOP with or without medication allowing for additional surgeries. As first surgery, 360° catheter-assisted trabeculotomy had a tendency to higher surgical success than other surgical approaches, while cyclodestructive procedures had lowest., Conclusions: We found very promising surgical results in our childhood glaucoma patient group. Surgical success in both congenital and secondary glaucoma was high., (© 2021 The Authors.
