PURPOSE: To describe the causes of ectopia lentis (EL) and the outcomes after surgery in a Danish population.SETTING: The Eye Clinic Rigshospitalet and Kennedy Center in Copenhagen.DESIGN: Retrospective cohort study.METHODS: Medical records of patients with nontraumatic EL born after 1980 and seen at the Eye Clinic Rigshospitalet and Kennedy Center from 1983 to 2019 were reviewed. Clinical information regarding family history, comorbidities, genetic workup, ophthalmological examinations, and surgical history was retrieved.RESULTS: 72 patients (38 males), of whom 68 had bilateral EL (94.4%) were identified. Marfan syndrome (MFS) was found in 34 (47.2%) and biallelic variants in ADAMTSL4 in 4 (5.6%). Surgery was performed in 38 (52.8%) patients, 66 eyes, with a median age at the time of first eye surgery of 8.4 years (range 0.8 to 39.0 years) and a follow-up of 2.3 years (range 0 to 25.7 years). Intraocular lenses were implanted in 9 (23.7%) (11 eyes). Corrected distance visual acuity improved from 0.7 to 0.2 logMAR (median) in right eyes and from 0.7 to 0.3 logMAR in left eyes postoperatively. 21 patients (56.8%), 42 eyes, did not experience any surgery-related complications. 3 patients (3 eyes) experienced a perioperative tear in the posterior capsule. Temporary postoperative ocular hypertension was reported in 3 patients (7.9%) (3 eyes), and 2 patients (5.4%) (2 eyes) developed persistent ocular hypertension. There were no cases of postoperative retinal detachment.CONCLUSIONS: The main reason for EL was MFS. Surgery improved visual acuity, and postoperative ocular hypertension was the most common complication, whereas retinal detachment was not observed.

Purpose. To systematically review the results of comparative studies of modern cataract surgery in pediatric uveitis with or without intraocular lens (IOL) implantation and to perform comparative meta-analyses to compare visual acuity outcomes and complication rates. Methods. On 12 November 2020, we systematically searched the Cochrane Central, PubMed/MEDLINE, EMBASE, ClinicalTrials.gov, and all affiliated databases of the Web of Science. Two authors independently reviewed studies and extracted data. Studies were reviewed qualitatively in text and quantitatively with meta-analyses. Outcome measures were preoperative and postoperative best-corrected visual acuity (BCVA), inflammation control, and rates of postoperative complications. Results. Ten studies of 288 eyes were eligible for review of which the majority were eyes with juvenile idiopathic arthritis-associated uveitis. Summary estimates revealed that the BCVA was better in pseudophakic eyes vs. aphakic eyes (1-year postoperative: −0.23 logMAR, 95% CI: −0.43 to −0.03 logMAR, P = 0.027 ; 5-year postoperative: −0.35 logMAR, 95% CI: −0.51 to −0.18 logMAR, P = 0.000036 ). Pseudophakic eyes had more visual axis opacification (OR 6.76, 95% CI: 2.73 to 16.8, P = 0.000036 ) and less hypotony (OR 0.19, 95% CI: 0.04 to 0.95, P = 0.044 ). Conclusions. In modern era cataract surgery on eyes with pediatric uveitis with IOL implantation leads to satisfactory and superior visual outcomes and no differences in complication rates apart from an increased prevalence of visual axis opacification and a decreased prevalence of hypotony when compared to aphakia. However, limitations of the retrospective design and the presence of selection bias necessitate a careful interpretation.

Purpose Anterior polar cataract is an opacity in the anterior capsule of the lens. Anterior polar cataract has historically been considered as a relatively benign condition. The purpose of this study was to estimate the prevalence of anterior polar cataract, to identify the risk factors for amblyopia and to estimate the risk of developing amblyopia in children with anterior polar cataract. Methods The medical records for patients with congenital cataracts at the Eye Clinic Rigshospitalet, Rigshospitalet-Glostrup and Kennedy Center covering a ten year period from 2007 to 2016 (both metres years included) were reviewed. Results A total of 54 patients with anterior polar cataract were identified. The majority had unilateral anterior polar cataract (72%). Family history of childhood cataracts was frequent (27%) of patients with bilateral anterior polar cataract. There was an overrepresentation of female patients (70%). Amblyopia was found in 55% of the patients. The causes were primarily hypermetropic anisometropia (70%) and astigmatism (52%). Axial length was on average 0.88 mm (SD 0.44) shorter in the eye with anterior polar cataract compared to fellow eyes. Conclusion Anterior polar cataract is a highly amblyogenic condition not because of a visually obstructing lens opacity but because of refractive errors, primarily hypermetropic anisometropia and astigmatism. Anterior polar cataract seems to represent an anomaly in global eye development resulting in reduced axial length. Patients with anterior polar cataract should be monitored to detect and treat amblyopia in time.

Non-physicians such as nurses are trained to give injections into the vitreous body of the eye to meet the increasing demand for intravitreal therapy with vascular endothelial growth factor inhibitors against common eye diseases, e.g. age-related macular degeneration and diabetic retinopathy. We systematically reviewed the existing literature to provide an overview of the experiences in this transformational process.We searched for literature on 22 September 2015 using PubMed, Embase, the Cochrane Library, CINAHL and the Web of Science. Eligible studies had to address any outcome based on non-physician delivered intravitreal therapy regardless of the study design. Being non-physician was defined as the injecting personnel not being a physician, but no further restrictions were made.Five studies were included with a total of 31,303 injections having been performed by 16 nurses. The studies found that having nurses perform the intravitreal injections produced to a short-term capacity improvement and liberated physicians for other clinical work. Training was provided through courses and direct supervision. The rates of endophthalmitis were 0-0.40‰, which is comparable to reported rates when the intravitreal therapy is given by physicians.Non-physician delivered intravitreal therapy seems feasible and safe.
