Spontaneous collapse of an iris stromal cyst in a young child.

A 4-month-old girl was referred for evaluation of an anterior chamber cyst in the left eye. Examination under anesthesia (EUA) revealed a large iris stromal cyst in the anterior chamber involving the angle and the pupillary border, with touch of the corneal endothelium and anterior lens capsule. Intraocular pressure was normal. There was no anisometropic refractive error by retinoscopy. Close observation with amblyopia management was recommended as the pupil was only partially occluded by the cyst, and there was a clear red reflex around the cyst. Repeat EUA 6 months following diagnosis showed spontaneous collapse of the cyst. There was no recurrence noted at her most recent follow-up, 2 years after presentation, and most of the pupillary axis remains unobstructed by the cyst. The patient continues to be followed to monitor for possible cyst progression, anisometropia, and development of amblyopia. Though rare, spontaneous resolution of an iris stromal cyst may occur and thus, observation may be considered, particularly if the cyst is not causing anterior segment complications or obstruction of the visual axis.

Congenital Cataracts With Thin Lenses (Leptophakia) in Children: Morphology and Surgical Outcomes.

PURPOSE: To determine the morphology and postoperative outcomes of pediatric cataracts with thin (leptophakic) lenses. DESIGN: Retrospective comparative clinical cohort study. METHODS: We identified the records of pediatric patients who had undergone cataract surgery between 2018 and 2023 and lens thickness less than 2 standard deviations of age-stratified normal eyes in the general population. Matching controls were identified based on sex, age at surgery, and intraocular lens implant status. Data abstracted include axial length, anterior chamber depth, lens thickness, visual acuity, intraocular pressure, and surgical details. RESULTS: A total of 13 eyes from 7 patients were identified to be leptophakic, 8 of which had matching controls. Compared with the control eyes, leptophakic eyes had thinner lenses (2.74 ± 0.39 mm vs 4.82 ± 1.01 mm, P < .01) with comparable anterior chamber depth (3.28 ± 0.76 mm vs 2.98 ± 1.28 mm, P = .13) and axial lengths (19.17 ± 2.61 mm vs 20.76 ± 1.76 mm, P = .20). Following cataract surgery, visual acuity improved for both the leptophakic and control cohorts within 2.5 months postoperatively (-0.68 ± 0.37 logMAR vs -0.06 ± 0.42 logMAR, P = .03) and at 1-2 years postoperatively (-1.58 ± 1.03 logMAR vs -0.60 ± 0.49 logMAR, P = .22) without any glaucoma-related adverse events. Of note, 5 of 13 leptophakic eyes (38%) were found to have posterior capsular ruptures intraoperatively. CONCLUSIONS: Leptophakic eyes demonstrated similar intraoperative and short-term postoperative outcomes when compared to control eyes, although vigilance for posterior capsular defects and ruptures may be necessary.

Non-nasal, atypical retinochoroidal coloboma in pediatric patients: Case series and review.

Purpose: To report 2 cases of atypically located, non-nasal colobomas in the pediatric population. Observations: A 3-week-old female neonate with no known past ocular or medical history was diagnosed with temporal iris and chorioretinal coloboma with tractional membranes upon examination under anesthesia and imaging. A 9-year-old female with a history of bilateral sensorineural hearing loss and left mild hydronephrosis presented with a temporal chorioretinal coloboma associated with retinal detachment. Conclusions and importance: Very few cases of atypically located, non-nasal pediatric colobomas have been reported, and they lack a clear cause or mechanism of formation. Continued documentation of their occurrence and research into their formation at a molecular and embryological level are warranted to better understand their pathogenesis.

Intraocular Pressure Spike Following Stand-Alone Phacoemulsification in the IRIS® Registry (Intelligent Research in Sight).

PURPOSE: To evaluate risk factors for intraocular pressure (IOP) spike after cataract surgery using the IRIS® Registry (Intelligent Research in Sight). DESIGN: Retrospective clinical cohort study. PARTICIPANTS: Adults with IRIS Registry data who underwent stand-alone phacoemulsification from January 1, 2013, through September 30, 2019. METHODS: Intraocular pressure spike was defined as postoperative IOP of > 30 mmHg and > 10 mmHg from the baseline within the first postoperative week. Odds ratios (ORs) for demographic and clinical characteristics were calculated with univariable and multivariable logistic regression analyses. MAIN OUTCOME MEASURES: Incidence and OR of IOP spike. RESULTS: We analyzed data from 1 191 034 eyes (patient mean age, 71.3 years; 61.2% female sex; and 24.8% with glaucoma). An IOP spike occurred in 3.7% of all eyes, 5.2% of eyes with glaucoma, and 3.2% of eyes without glaucoma (P < 0.0001). Multivariable analyses of all eyes indicated a greater risk of IOP spike with higher baseline IOP (OR, 1.57 per 3 mmHg), male sex (OR, 1.79), glaucoma (OR, 1.20), Black race (OR, 1.39 vs. Asian and 1.21 vs. Hispanic), older age (OR, 1.07 per 10 years), and complex surgery coding (OR, 1.22; all P < 0.0001). Diabetes (OR, 0.90) and aphakia after surgery (OR, 0.60) seemed to be protective against IOP spike (both P < 0.0001). Compared with glaucoma suspects, ocular hypertension (OR, 1.55), pigmentary glaucoma (OR, 1.56), and pseudoexfoliative glaucoma (OR, 1.52) showed a greater risk of IOP spike and normal-tension glaucoma (OR, 0.55), suspected primary angle closure (PAC; OR, 0.67), and PAC glaucoma (OR, 0.81) showed less risk (all P < 0.0001). Using more baseline glaucoma medications was associated with IOP spike (OR, 1.18 per medication), whereas topical ß-blocker use (OR, 0.68) was protective (both P < 0.0001). CONCLUSIONS: Higher baseline IOP, male sex, glaucoma, Black race, older age, and complex cataract coding were associated with early postoperative IOP spike, whereas diabetes and postoperative aphakia were protective against a spike after stand-alone phacoemulsification. Glaucomatous eyes demonstrated different risk profiles dependent on glaucoma subtype. The findings may help surgeons to stratify and mitigate the risk of IOP spike after cataract surgery.

Serous Retinal Detachment in a Patient With a Port-Wine Birthmark Associated With Prostaglandin Analog Therapy.

An 11-year-old girl with a port-wine birthmark (PWB), diffuse choroid hemangioma (DCH), and glaucoma experienced decreased vision upon starting treatment with bimatoprost. The patient was switched to latanoprostene bunod. Her vision remained reduced. Shortly after, she was diagnosed with serous retinal detachment (SRD). Both SRD and vision improved following prostaglandin analog (PGA) cessation. Patients with PWB are likely to have DCH and glaucoma. DCH itself poses a risk factor for SRD. Certain glaucoma management modalities may further increase this risk. This report highlights the importance of regular surveillance for SRD in patients with DCH who are receiving PGA.

Compliance with Web Content Accessibility Guidelines in Ophthalmology Social Media Posts.

This is a cross-sectional analysis of publicly available Internet data to examine compliance to Web Content Accessibility Guidelines (WCAG) on patient education social media posts in ophthalmology. WCAG ensures web content accessibility for those with disabilities (including visual impairment). Social media posts were sampled from 10 ophthalmology patient education social media pages and 10 non-ophthalmology (cardiopulmonary) pages as the comparison group. Three independent reviewers graded the selected posts based on the WebAIM© WCAG 2 checklist adapted for social media posts. Validated accessibility standard labels: "0" for not meeting any standards, "1" for meeting bare minimum accessibility requirements, "2" for meeting legal accessibility requirements, or "3" for exceeding accessibility requirements. There were no significant differences between ophthalmology and non-ophthalmology posts in receiving high vs. low WCAG grades. 49% of ratings for ophthalmology social media posts showed no compliance with any WCAG. The most common reasons that ophthalmology posts failed to meet criteria were due to color and contrast issues (38.9%). Most ophthalmology social media posts had low WCAG scores, indicating poor compliance to WCAG. Because social media is highly visual, reduced compliance to WCAG may create barriers for low vision individuals to successfully access patient education social media content.

The Burden of Pediatric Visual Impairment and Ocular Diagnoses in Barbados.

Visual impairment (VI) negatively affects a child's quality of life. The prevalence of VI in the Caribbean is nearly three times higher than in the United States, but the causes remain uncertain. This study leverages Barbados' unique eye care system to survey the eye diseases and VI prevalence in Barbadian children. Medical records of all patients aged <19 years who received ophthalmic care in Barbados' two public eye care centers between January and December 2019 were reviewed, capturing the entirety of public pediatric eye care within the study period. Age at the first visit to the clinic and at the final visit in 2019, sex, best-corrected visual acuity (BCVA), past medical history, and clinical diagnoses were extracted and analyzed. VI was defined as a BCVA of 6/12 or worse in the better-seeing eye. There were 3278 patient records with a mean age at the first visit of 7.8 ± 3.9 years. There were 80 (2.4%) children with VI, 62.5% of which were attributed to amblyopia. A total of 94% of VI was preventable or treatable. The most common diagnoses were refractive error (87.5%), strabismus (27.5%), and allergic eye disease (20.0%). Amblyopia is the major cause of pediatric VI in Barbados and is largely avoidable.

Outcome measures in childhood glaucoma: a systematic review of randomized controlled trials.

PURPOSE: To synthesize the outcome measures used by randomized controlled trials (RCTs) for childhood glaucoma. METHODS: MEDLINE, EMBASE, and Scopus were searched from inception to February 17, 2023. Randomized controlled trials and observational studies related to childhood glaucoma were included. Primary and secondary outcomes were extracted and the data was used to generate a literature review. RESULTS: This review identified 42 unique reports pertaining to childhood glaucomas. Most of the studies originated from Egypt, India, and the USA. Intraocular pressure (IOP) outcomes were the most frequent outcomes studied, followed by clinical outcomes and safety outcomes. Clinical outcomes were the most common secondary outcomes studied, followed by IOP outcomes and safety outcomes. CONCLUSIONS: This systematic review found heterogenous outcomes with IOP outcomes as the most studied primary outcome. As the remaining outcomes were not consistently utilized, this review highlights the need for a consensus on studies of pediatric glaucoma.

Commercial Gene Panels for Congenital Anterior Segment Anomalies: Are They All the Same?

PURPOSE: We compared next generation sequencing multigene panels (NGS-MGP) from 5 commercial laboratories to inform ophthalmologists' decision making in diagnostic genetic testing for congenital anterior segment anomalies (CASAs). DESIGN: Comparison of commercial genetic testing panels. METHODS: This observational study gathered publicly available information on NGS-MGP from 5 commercial laboratories for the following: cataracts, glaucoma, anterior segment dysgenesis (ASD), microphthalmia-anophthalmia-coloboma (MAC), corneal dystrophies, and Axenfeld-Rieger syndrome (ARS). We compared gene panel composition, consensus rate (genes covered by all the panels per condition, "concurrent"), dissensus rate (genes covered by only 1 panel per condition, "standalone"), and intronic variant coverage. For individual genes, we compared publication history and association with systemic conditions. RESULTS: Altogether, cataract, glaucoma, corneal dystrophies, MAC, ASD, and ARS panels tested 239, 60, 36, 292, and 10 discrete genes, respectively. The consensus rate varied between 16% and 50%, and the dissensus rate varied between 14% and 74%. After pooling concurrent genes from all conditions, 20% of these genes were concurrent in 2 or more conditions. For both cataract and glaucoma, concurrent genes had significantly stronger correlation with the condition than standalone genes. CONCLUSIONS: The genetic testing of CASAs using NGS-MGPs is complicated, owing to their number, variety, and phenotypic and genetic overlap. Although the inclusion of additional genes, such as the standalone ones, might increase diagnostic yield, these genes are also less well studied, indicating uncertainty over their role in CASA pathogenesis. Rigorous prospective diagnostic yield studies of NGS-MGPs will aid in making decisions of panel selection for the diagnosis of CASAs.

Intraocular Pressure Changes Following Stand-Alone Phacoemulsification: An IRISɌ Registry Analysis.

PURPOSE: To describe real-world intraocular pressure (IOP) changes following stand-alone cataract surgery by comparing postoperative IOP to phakic fellow eyes. DESIGN: Retrospective clinical cohort study. METHODS: A total of 1,334,868 patients (336,060 with glaucoma and 998,808 without glaucoma) in the IRIS® Registry (Intelligent Research in Sight) underwent stand-alone phacoemulsification from 1 January 2013 to 30 September 2019 with a fellow eye that had subsequent cataract surgery. Postoperative daily mean IOP was compared between surgical and control eyes from postoperative day 1 to 90. A generalized linear model determined when the postoperative daily mean IOP stabilized to calculate a final mean IOP, which was then compared to baseline IOP. RESULTS: Postoperative daily mean IOP was initially greater for surgical than for control eyes because of an early postoperative IOP spike. By postoperative day 13, postoperative daily mean IOP was significantly lower for surgical than for control eyes every day through postoperative day 90 (P < .001). There was a mean (SD) decrease from baseline to final mean IOP of 1.55 (3.52) mm Hg or 7.79% for all surgical eyes, 1.91 (3.93) mm Hg or 8.89% for surgical eyes with glaucoma, and 1.37 (3.28) mm Hg or 7.24% for surgical eyes without glaucoma, respectively. There was a statistically significant decrease from baseline to the final mean IOP for all surgical eyes, surgical eyes without glaucoma, and all categories of pre-glaucoma and glaucoma (P < .0001 for all, excluding uveitic glaucoma [P = .0016]). CONCLUSIONS: Eyes both with and without glaucoma that underwent stand-alone phacoemulsification had a significant decrease in IOP through the 90-day postoperative period compared to baseline and phakic fellow eyes.

A colorimetric chemical tongue detects and distinguishes between multiple analytes.

The rate-limiting step for diagnostics development is the discovery and validation of biomarker analytes. We describe a new analyte-agnostic and label-free approach based on colorimetric reactions involving type I polymerization photoinitiators. We demonstrate that a chemically diverse array of hydrogels embedded with cleaved type I photoinitiators could act as microreactors, undergoing colorimetric reactions with bound analytes. The colorimetric signatures produced were visually distinctive and readable with a flatbed document scanner. Signatures of a broad range of sample types were accurately differentiated by unsupervised clustering without knowledge of any analytes bound to the array. The principles described have the potential to enable scalable and cost-effective analysis of complex samples.

Outcomes of Anterior Chamber, Sulcus, and Pars Plana Glaucoma Drainage Device Placement in Glaucoma Patients.

Purpose: To assess outcomes of anterior chamber (AC), sulcus, and pars plana (PP) glaucoma drainage device (GDD) placement in glaucoma patients. Patients and Methods. Retrospective evaluation of glaucoma patients who underwent GDD insertion in the AC, sulcus, or PP at Massachusetts Eye and Ear between November 2016 and May 2021. Patients who received AC, sulcus, and pars plana tubes were selected using simple random sampling, and the first 40 patients meeting inclusion criteria were analyzed. Main outcome measures were cumulative success probabilities from Kaplan-Meier (KM) analyses, intraocular pressure (IOP), medication burden, and complication rates. Results: The PP group had a larger proportion of Ahmed GDDs and was younger on average with less severe glaucoma compared to patients with AC or sulcus tubes. The PP group had a higher proportion of mixed-mechanism glaucoma and lower proportion of primary open-angle glaucoma. With success defined as IOP reduction ≥20% and 5 < IOP ≤ 21 mm Hg, the Kaplan-Meier cumulative success probabilities for all three GDD locations were not significantly different. No significant differences were found in complication rates between all groups after 3 months. Patients with PP GDD had significantly lower medication burden than those with AC or sulcus GDDs up to 1.5 years postoperatively (1.7 ± 1.1, 3.0 ± 1.4, and 2.8 ± 1.2 for PP, AC, and sulcus, respectively; P=0.017). Conclusion: PP GDDs may be more effective in lowering medication burden than AC or sulcus tubes without compromising long-term safety.

Congenital corneal opacities as a new feature in an unusual case of White-Sutton syndrome.

A 2-week-old girl presented with bilateral congenital corneal opacities. Additional systemic manifestations included microcephaly, patent foramen ovale, and poor feeding. Patient and parents underwent whole exome sequencing trio analysis that revealed a de novo pathogenic variant in POGZ (p.Val1150GlyfsX8), which is causative of the White-Sutton syndrome. This rare genetic condition is usually associated with intellectual and developmental delay, facial dysmorphism, strabismus, refractive error, and retinal changes. To our knowledge, this is the first reported case of White-Sutton syndrome presenting with congenital corneal opacities.

Factors Associated With Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) Complications and Failure in Children.

PURPOSE: To identify the factors associated with the complications and failure of gonioscopy-assisted transluminal trabeculotomy (GATT) in children. DESIGN: Retrospective case series. METHODS: This study was conducted in an institutional setting in a pediatric population (aged <18 years) who had undergone GATT. Records were reviewed, and pre- and postoperative intraocular pressures (IOP), extent of angle treated, medications, complications, and failure were recorded. Failure was defined as IOP >21 mm Hg or <5 mm Hg, absence of at least 20% IOP reduction, performance of additional IOP-lowering surgery, or loss of light perception vision. RESULTS: A total of 74 eyes of 57 patients were included (mean age, 7.1 years). Over a median follow-up period of 28.5 months, 36 eyes (48.6%) failed. IOP spikes occurred in 25 eyes (33.8%) and were a significant risk factor for failure (hazard ratio [HR] = 2.17; P = .0207). Postoperative hyphema was a significant risk factor for IOP spike (HR = 4.13, P = .003) but not for failure (HR = 0.7, P = .2977). The risk of IOP spike was lowest in eyes treated with nonsteroidal anti-inflammatory drugs (NSAIDs; HR = 0.27, P = .0016). The risk of failure increased significantly in eyes that received topical corticosteroids (compared to NSAIDs; HR = 5.72, P = .0005), in eyes with <360○ incisions (HR = 4.69, P < .0001), and in younger children. CONCLUSIONS: GATT is a reasonably effective procedure in childhood glaucoma. Postoperatively, the use of topical NSAIDs (without corticosteroid) may decrease the risk of failure. Eyes with IOP spikes without hyphema are at the highest risk for failure.
