AimsTo determine the nature and prevalence of ophthalmological findings for a cohort of children in a paediatric cochlear implant program and to assist the clinician in devising an investigative plan for this population.MethodsRetrospective medical record review of children who underwent multichannel cochlear implantation at a tertiary care hospital between February 1996 and July 2008.ResultsIn all, 141 children (mean age 28 months, range 16 months to 9 years) had complete medical record documentation consisting of orthoptic and opthalmological examination, including cycloplegic refraction. A total of 59 children (41.8%) had ocular abnormalities with refractive errors being the most common abnormality. Hypermetropia was the most common refractive error and was found in 21 children (14.8%). Strabismus was found in six patients, with constant esotropia being the most common. Ocular pathology (excluding refractive or muscle abnormalities) were found in nine patients (6.3%). Three patients had syndromes associated with ocular findings including Waardenburg and Usher syndrome. During the follow-up period, 14 children were fitted with prescription lenses, 3 had strabismus surgery, and 2 underwent ptosis.ConclusionsRoutine orthoptic and ophthalmologic examination can be beneficial in the initial evaluation of children assessed for cochlear implants. Electroretinography is useful in evaluating children with unexplained congenital sensorineural hearing loss, suggestive symptoms including night blindness, unexplained reduction in visual acuity, or delayed motor milestones. Routine yearly follow-up may aid in the detection of changing refractive errors and the possibility of later-onset retinal degeneration. [ABSTRACT FROM AUTHOR]

Purpose: To report the margin control process and rate of recurrence of periocular basal cell carcinomas (BCCs) managed by en-face, frozen section margin controlled (FSC), excision by a single surgeon with a 3-year follow-up., Methods: A retrospective analysis of all histopathologically proven cases of periocular BCC who underwent surgical excision with intra-operative, en-face, FSC, excision by a single surgeon from 2015 to 2019 was performed. Patients with less than 3-year follow-up were offered a virtual appointment to determine possible recurrence., Results: A total of 88 BCC excisions from 86 patients were reviewed. Minimum 3-year follow-up data is available for 73 patients. The most common location and histological subtype was the lower eyelid and nodular BCC, respectively (47% and 83% of cases). Primary BCC (pBCC) comprised 98% (86/88) of cases and recurrent BCC (rBCC) comprised 2% (2/88) of cases. Negative frozen section margins were achieved in 93% (82/88) of excisions on the day of surgery. The overall recurrence rate during this time was 1.4% (1/73) at minimum 3 years., Conclusion: Periocular BCC can be managed effectively by en-face, FSC, excision, with a high cure rate and low recurrence rate comparable to alternative excision techniques such as Moh's micrographic surgery. Advantages of en-face excision include same-day excision and reconstruction and reduced theatre time. Primary nodular BCCs with clear margins can be considered for early discharge with advice to self-monitor., (© 2024. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.)

Angiosperms are the cornerstone of most terrestrial ecosystems and human livelihoods 1,2 . A robust understanding of angiosperm evolution is required to explain their rise to ecological dominance. So far, the angiosperm tree of life has been determined primarily by means of analyses of the plastid genome 3,4 . Many studies have drawn on this foundational work, such as classification and first insights into angiosperm diversification since their Mesozoic origins 5-7 . However, the limited and biased sampling of both taxa and genomes undermines confidence in the tree and its implications. Here, we build the tree of life for almost 8,000 (about 60%) angiosperm genera using a standardized set of 353 nuclear genes 8 . This 15-fold increase in genus-level sampling relative to comparable nuclear studies 9 provides a critical test of earlier results and brings notable change to key groups, especially in rosids, while substantiating many previously predicted relationships. Scaling this tree to time using 200 fossils, we discovered that early angiosperm evolution was characterized by high gene tree conflict and explosive diversification, giving rise to more than 80% of extant angiosperm orders. Steady diversification ensued through the remaining Mesozoic Era until rates resurged in the Cenozoic Era, concurrent with decreasing global temperatures and tightly linked with gene tree conflict. Taken together, our extensive sampling combined with advanced phylogenomic methods shows the deep history and full complexity in the evolution of a megadiverse clade., (© 2024. The Author(s).)

Significance: We evaluate the relationship between tear film osmolarity measurements and quality of vision in patients presenting for routine eye clinic appointments. We found that the hyperosmolar group (>316 mOsm/L) had a worse quality-of-vision score than the normal osmolarity group, with glare being the most problematic symptom., Purpose: Quality of vision is a perception and measure of real-world vision, which is not measured routinely in a clinical setting. This study aimed to evaluate the relationship between tear film osmolarity measurements and quality of vision in patients presenting for routine eye clinic appointments., Methods: This was an observational nonrandomized study. The participants were placed in groups based on tear film osmolarity (normal, ≤316 mOsm/L; hyperosmolar, >316 mOsm/L; or a difference of >8 mOsm/L between each eye). Thirty-three participants were enrolled in the study, of whom 22 were deemed to have a hyperosmolar tear film. A 30-item questionnaire including 10 symptoms rated on scales of frequency, severity, and bothersomeness was administered to participants in both groups. The quality-of-vision score ranged from 25 to 100 points, with lower scores indicating better quality of vision., Results: The hyperosmolar group had a significantly worse quality-of-vision score than the normal osmolarity group across all three scales; mean differences for frequency, severity, and bothersomeness were 12.66 ± 9.75 (p=0.003), 9.44 ± 7.45 (p=0.003), and 11.90 ± 11.14 (p=0.008), respectively. Of the 10 symptoms that were included in the questionnaire, glare was the most problematic in the hyperosmolar group., Conclusions: In this study, we demonstrated a significant relationship between tear film hyperosmolarity and quality of vision, as patients with hyperosmolar tear films had worse quality of vision., Competing Interests: Conflict of Interest Disclosure: None of the authors have reported a financial conflict of interest., (Copyright © 2024 American Academy of Optometry.)

In this report, we present a case of a patient with a 30-year history of orbital asymmetry who presented with metastatic human epidermal growth factor receptor 2 ( HER2 ) positive lacrimal/salivary gland ductal adenocarcinoma. The patient was treated with chemoradiotherapy and trastuzumab. Tumours of lacrimal gland origin are rare, and unfortunately can frequently present in late stage. There are no current guidelines on the optimal treatment of metastatic lacrimal gland tumours, in particular those with HER2 amplified malignancy. This case highlights a unique presentation of a rare disease, and the potential for targeted therapy., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Aims: To review the distribution of histopathological diagnoses and visual outcome of orbital biopsy in an Irish tertiary referral centre over a 10-year period., Methods: This was a retrospective, clinical-histopathological case series. Clinical records of all patients who underwent orbital biopsy between January 2008 and January 2018 in the Mater Misericordiae University Hospital were reviewed using data collected from theatre logbooks and hospital-based medical records., Results: A total of 83 orbital biopsies in 77 patients were included for analysis in this study. The mean age was 55.7 ± 18.41 years. The mean follow-up period was 1.87 ± 2.097 years. The most common presenting symptoms and signs were pain (22.3%) and proptosis (27.6%). Most lesions were located in the extraconal space (65%), with incisional biopsy (65%) being the most common technique used to gain a sample for histopathological diagnosis. Histopathology analysis of the biopsies revealed malignant tumours (27, 32.5%), benign tumours (7, 8.4%), inflammation (26, 31.3%), and other diagnoses (23, 27%). Excluding patients who underwent exenteration procedures, no study patients suffered visual loss following orbital biopsy., Conclusions: Orbital biopsy serves as a safe diagnostic tool in managing orbital diseases. The breakdown of diagnosis in our patients is in line with international studies. No patients in our series suffered vision loss as a result of their orbital biopsy. This emphasises its use as a safe procedure in the diagnosis and management of patients with the orbital disease. Our data provides helpful guidance to clinicians when counselling patients for orbital biopsy., (© 2022. The Author(s).)

Objectives: To compare presentation of infectious keratitis during COVID-19 lockdown with previous years, assess relative severity, and compare outcomes between COVID-19 and pre-COVID-19 era groups., Methods: Acute presentations of infectious keratitis during a strict government-mandated COVID-19 lockdown period were analysed retrospectively (March-May 2020). Data were compared with the same periods in 2018-2019. The clinical notes of patients undergoing corneal scrapes were reviewed, and data were collected on treatment, culture growth, surgical interventions, visual outcomes, admission rates, and risk factors., Results: There were 37% fewer presentations of infectious keratitis to the ED in 2020 ( N  = 29, 47, and 45, respectively). Risk factor profiles and microbial data were similar across all periods. Admission rates and use of fortified antibiotics were lower in 2020. COVID-19 era cases recovered less vision (LogMAR 0.26, 0.67, and 0.45, respectively; p  = 0.04) and were more likely to require surgical intervention (10%, 4%, and 2%, respectively; OR 3.4 (CI 0.7-17.9, p  = 0.1))., Conclusion: A concerning fall in presentations of infectious keratitis to ED during the pandemic lockdown was observed. Though societal behaviour changed during the lockdown, our data suggest it is unlikely that the incidence of infectious keratitis fell significantly. It is unclear how and where these patients were treated. We postulate that lower levels of visual recovery and higher rates of surgical intervention may have been caused by delays in accessing care. To minimise avoidable ocular morbidity as COVID-19 resurges, we must communicate clearly with patients and health professionals on how to access available emergency eye care services., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Barry Power et al.)

Background: First Irish National Corneal Transplant Registry report., Aim: To report about current corneal transplantation practices in Ireland including patient demographics, indications and types of transplant performed and to compare the findings with other developed countries., Methods: Nationwide retrospective review of the corneal transplants performed in Ireland between 2016 and 2019., Results: Overall, 536 keratoplasties were carried out: 256 (47.8%) Penetrating Keratoplasties (PK), 212 (39.6%) Descemet Stripping Automated Endothelial Keratoplasties (DSAEK), 30 (5.6%) Descemet Membrane Endothelial Keratoplasties (DMEK), and 25 (4.7%) Deep Anterior Lamellar Keratoplasties (DALK). The most common indication was Keratoconus (KC, 19%), followed by Fuchs endothelial dystrophy (FED, 18.8%), and Pseudophakic bullous keratopathy (PBK, 17%). KC (34%) and re-grafting (17%) were the leading indications for PK, whereas FED and PBK were the major indications for DSAEK (38% and 33%) and DMEK (67% and 20%), respectively. During the period studied, the number of transplants increased from 11.3 to 14 grafts per month. The number of PKs remained stable, whereas Endothelial Keratoplasties, DSAEK and DMEK, increased (3.8 to 5.6 and 0.2 to 1.6 per month, respectively), becoming the most commonly performed grafts since 2018. Only a small number of DALK were performed., Conclusions: Corneal transplantation in Ireland is following international trends as endothelial procedures have become the most common approach since 2018. However, a low overall number of transplants is performed in Ireland compared with other countries suggesting that care pathways should be implemented to improve access to corneal transplantation.

Conjunctival epithelial inclusion cysts are an infrequent complication in anophthalmic sockets. The ocular prosthesis may become difficult to retain or it may cause local discomfort. Treatment options described include surgical resection, marsupialisation, and the use of injected sclerosing agents. We present a case of a 27-year-old female who developed a conjunctival epithelial inclusion cyst two years after a left eye evisceration. This invariably caused the ocular prosthesis to become cosmetically unacceptable. Trichloroacetic acid 20% (TCA) was injected intracystically as a minor procedure at the slit lamp. Four months later there was no recurrence of the cyst and the prosthesis retained an excellent position in the socket. This case highlights the successful treatment of a conjunctival epithelial inclusion cyst with TCA (20%) without the need for a surgical procedure.

Purpose: To describe the first reported case of corneal crystalline deposition associated with the monoclonal antibody secukinumab (Cosentyx; Novartis, Basel, Switzerland) and the subsequent follow-up of the case., Methods: Case report., Results: An 18-year-old man was referred for a corneal opinion 1 year after commencing secukinumab monoclonal antibody therapy for ankylosing spondylitis. Crystalline corneal deposits were identified at a routine optometrist appointment. The same optometrist had documented normal anterior segment examination 2 years earlier. On examination, anterior stromal refractile crystals were visible in both corneas extending out to the limbus. The patient's best-corrected distance visual acuity was 20/20 bilaterally, and he was asymptomatic. Family history and systemic workup for other causes of crystal deposition were negative. By a process of elimination of other etiologies, we concluded that the monoclonal antibody secukinumab was responsible for the deposition. At the 1-year point of treatment with secukinumab, the patient remains asymptomatic and is still undergoing therapy., Conclusions: To the best of the authors' knowledge, this is the first report of corneal crystal deposition attributed to secukinumab. The number of monoclonal antibodies in use across multiple medical disciplines is increasing, and corneal specialists may see this presentation more frequently in the future. These drugs provide critical disease-modifying treatment to patients with debilitating systemic pathology. It is important that we understand the natural history of their side effects to allow their full utilization.

Purpose: To report a unique case of orbital inflammatory disease which was ultimately diagnosed as granulomatosis with polyangitis (GPA) and thus successfully treated., Observation: A 47 year-old man presented with a rapidly progressive necrotic soft tissue mass within the medial antero-superior aspect of the right eyelid and orbit. He also had transient retinal vasculitis in the left. Serology, histology and imaging were atypical of, but consistent with, GPA. He was thus successfully treated with intravenous rituximab followed by reconstruction of the medial eyelid., Conclusion and Importance: A high index of suspicion of GPA is required in orbital inflammatory disease, especially when typical diagnostic findings are absent.

While pyoderma gangrenosum (PG) most commonly affects the skin it can also involve other organs. It rarely affects the eye, orbit, or adnexa. Its early recognition and proper management with prompt initiation of immunosuppressive therapy are essential for the preservation of the eye and, in turn, vision, in these cases. Here, we review the limited literature already published regarding ocular involvement in PG.

Orbital cellulitis is a serious sight threatening and potentially life threatening condition which can be complicated by orbital abscess formation. Posterior subtenon (PST) injection of corticosteroid is commonly used in the treatment of posterior segment inflammation including post-operative macular oedema. We report a case of orbital abscess formation as a late complication of PST triamcinolone acetonide and discuss the presentation, diagnosis and management.

Background/aims: To report five cases of infectious keratitis following corneal inlay implantation for the surgical correction of presbyopia., Methods: This was a retrospective, observational case series. Five eyes of five patients were identified consecutively in two emergency departments during a 1-year period, from November 2013 to November 2014. Patients' demographics, clinical features, treatment and outcomes are described., Results: There were four female patients and one male, aged 52-64 years. Three patients had the KAMRA inlay (AcuFocus) and two had the Flexivue Microlens inlay (Presbia Coöperatief U.A.) inserted for the treatment of presbyopia and they presented from 6 days to 4 months postoperatively. Presenting uncorrected vision ranged from 6/38 to counting fingers. One patient's corneal scrapings were positive for a putatively causative organism, Corynebacterium pseudodiphtheriticum, and all patients responded to broad-spectrum fortified topical antibiotics. All patients lost vision with final uncorrected visual acuity ranging from 6/12 to 6/60 and best-corrected vision ranging from 6/7.5 to 6/12. Two patients' corneal inlays were explanted and three remained in situ at last follow-up., Conclusions: Infectious keratitis can occur at an early or late stage following corneal inlay implantation. Final visual acuity can be limited by stromal scarring; in the cases where the infiltrate was small and off the visual axis at the time of presentation, the final visual acuity was better than those patients who presented with larger lesions affecting the visual axis. Though infection may necessitate removal of the inlay, early positive response to treatment may enable the inlay to be left in situ., (Published by the BMJ Publishing Group Limited.

Descemet's stripping automated endothelial keratoplasty (DSAEK) is today recognised as the surgical procedure of choice for corneal endothelial dysfunction. The triple procedure (either staged or combined), whereby cataract surgery can be performed at the same time as endothelial keratoplasty, is well suited for patients with Fuch's endothelial dystrophy with decreased vision due to endothelial guttata, early stromal oedema and cataract formation. Recognised complications of DSAEK include donor graft detachment/dislocation, primary graft failure and pupillary block by air. Intraocular lens (IOL) opacification is a complication that is becoming apparent in patients who have undergone DSAEK and, to date, no definitive mechanism of such opacification has been discovered. Primary postoperative optic opacification of hydrophilic acrylic IOL designs has been attributed to the formation of calcium phosphate deposits. This has led to changes in lens designs, manufacturing processes and packaging. Secondary calcification is thought to be caused by environmental factors unrelated to the IOL model, such as breakdown of the blood-aqueous barrier. In this report, four cases of IOL anterior surface opacification are described in patients who required both cataract surgery and DSAEK. Only one case had cataract surgery and DSAEK performed concurrently, with the remainder having DSAEK performed at variable timeframes after cataract surgery., (2015 BMJ Publishing Group Ltd.)

A 68-year-old lady with metastatic malignant melanoma was treated with Ipilimumab. She presented to Eye Casualty unable to move her eyes. Physical examination confirmed ophthalmoplegia and identified proptosis bilaterally. Radiological imaging showed bilateral enlargement of all the extra-ocular muscles suggestive of thyroid eye disease. Laboratory investigations found this patient to be euthyroid. A diagnosis of thyroid-like orbitopathy secondary to Ipilimumab therapy was made. Thyroid function tests should be performed for all patients prior to their commencement of Ipilimumab. Thyroid-like eye disease may develop in patients treated with Ipilimumab even if they remain euthyroid.

Objectives: To examine orbital implant exposure rates following enucleation and evisceration., Methods: A retrospective chart review of all patients who underwent an evisceration or enucleation in a single centre over a 5-year period was performed. The indication for surgery, the type and size of orbital implant used, details of the surgical technique adopted and the postoperative complications observed, in particular orbital implant exposure, were recorded., Results: Over a 5-year period 24 patients had enucleation and 14 had evisceration; 22 of these procedures were performed by an ophthalmic surgeon with a special interest in orbit and oculoplastics while the remaining 16 procedures were performed by 5 ophthalmic surgeons with other sub-specialty interests. Orbital implant exposure occurred in 8 cases. One case had been performed by the first of these surgeons described. Implant exposure occurred in 4% of cases performed by this surgeon. The remaining 7 cases had been performed by the group of surgeons with sub-specialty interests outside of orbit and oculoplastics. Implant exposure occurred in 48% of cases performed by this group., Conclusions: Orbital implant exposure remains a significant cause of morbidity in patients undergoing enucleation and evisceration. Rates of orbital implant exposure were significantly lower when surgery was performed by an orbital surgeon. Differences in surgical technique are the most likely explanation.

Heavy eye phenomenon can be cosmetically unaccepted due to significant pseudoproptosis and hypotropia. We highlight the salient features of this condition, and report successful cosmetic outcome following a staged procedure comprising orbital decompression and horizontal recti surgery.
