Purpose: To determine the outcomes of sickle cell retinopathy (SCR) patients who experienced at least one episode of being lost to follow-up (LTFU) compared to those who attended all appointments.

Methods: Adult SCR patients who visited Wills Eye Hospital Retina service (January 2012-December 2021) with >2 visits were reviewed for LTFU events, defined as failure to return for a follow-up appointment within 6 months of the scheduled date.

Results: One hundred and eighty-one eyes of 94 patients were included.

To compare the anatomic and visual acuity (VA) outcomes of rhegmatogenous retinal detachment (RRD) repair in eyes with a multifocal intraocular lens (IOLs) and eyes with monofocal IOLs. This retrospective matched-cohort study comprised pseudophakic eyes that had pars plana vitrectomy (PPV) or PPV with scleral buckling for RRD. Eyes with multifocal IOLs (multifocal group) were matched with eyes with monofocal IOLs (control group) in a 1:2 ratio for age, sex, primary surgeon, timing of surgery from presentation, type of surgery, and macular status.

Purpose: This study compared two imaging grading techniques to assess the utility of longitudinal image-based analysis in retinopathy of prematurity (ROP) screening: (1) time-limited without image comparison (a proxy for bedside indirect ophthalmoscopy, termed sBIO) and time-unlimited with image comparison (for telemedicine grading, termed TELE) screening. We tested two hypotheses: (1) H1: TELE was superior to sBIO for the detection of change (Tempo)-same, better, or worse and (2) H2: granular data of change (e.g.

Purpose: Clinical trial cohorts frequently differ demographically from the overall population receiving treatment for the condition under study. Our study describes the racial, ethnic, and gender composition of the cohorts of retinal vein occlusion (RVO) macular edema (ME) clinical trials and compares this to the racial, ethnic, and gender composition of patients undergoing treatment for ME secondary to RVO from the (Intelligent Research in Sight) IRIS Registry.

Design: Retrospective observational case series Subjects: Participants in RVO-ME clinical trials that met the following inclusion criteria: conducted in the United States of America, Phase III completed, data reported between January 1, 2000, and January 1, 2020, and demographic information reported with results.

Purpose: We describe the case of an 80-year-old man with bilateral minocycline-induced retinal pigment epithelium (RPE) hyperpigmentation, which initially masqueraded as AMD. Secondarily, using multimodal imaging features, we propose a mechanism for the development of minocycline-induced RPE hyperpigmentation.

Observations: The patient was referred with concern for AMD given the presence of macular drusenoid deposits on optical coherence tomography.

Purpose: To describe a new retinal phenotype characterized by bilateral, multifocal, subretinal vitelliform lesions along the vascular arcades that we refer to as multifocal vitelliform paravascular retinopathy (MVPR).

Design: Observational case series.

Methods: Multimodal retinal imaging including color fundus photography, fundus autofluorescence and cross sectional and en-face optical coherence tomography was performed to evaluate and characterize the lesions of MVPR.

Article Synopsis
  • The study looked at how well surgeries helped people with a specific eye problem caused by sickle cell retinopathy, which can lead to retinal detachments.
  • It included 30 eyes from patients, showing that most of them (70%) had successful surgery that fixed the problem after 6 months, and nearly all (93.3%) had their retinas attached again by the end.
  • Overall, the surgeries improved their vision, but patients with more serious repeated problems didn't see much improvement.

To examine the characteristics of eyes with high-risk lattice degeneration treated with laser retinopexy and determine the indications, safety, and outcomes of the treatment. This interventional single-surgeon consecutive retrospective study was conducted at Wills Eye Hospital between 2014 and 2021. The series included eyes with lattice degeneration with high-risk lesions.

Purpose: To investigate outcomes of suprachoroidal triamcinolone acetonide (XIPERE, Bausch + Lomb) for the treatment of refractory postoperative cystoid macular edema.

Methods: Medical records of patients receiving suprachoroidal triamcinolone acetonide for postoperative cystoid macular edema were reviewed. Primary outcomes were visual acuity and central foveal thickness.

Background: Retrospective cohort study of 561 adult patients undergoing secondary intraocular lens (IOL) implantation by vitreoretinal surgeons at a single institution from April 2015 to December 2020.

Methods: Patient historical factors, intraoperative/postoperative complications, and outcomes of IOL type (anterior chamber IOL versus scleral sutured IOL versus scleral fixated IOL versus. sulcus) were assessed.

Purpose: To evaluate anatomic outcomes and surgeon response following the use of microserrated (Sharkskin, Alcon, Forth Worth, TX) internal limiting membrane (ILM) forceps compared with conventional (Grieshaber; Alcon) ILM forceps for peeling of the ILM.

Methods: Patients were prospectively assigned in a 1:1 randomized fashion to undergo ILM peeling using microserrated forceps or conventional forceps. Rates of retinal hemorrhages, deep retinal grasps, ILM regrasping, time to ILM removal, and surgeon questionnaire comparing the use of microserrated and conventional ILM forceps were analyzed.

Background And Objective: This study aimed to report retinal displacement incidence following rhegmatogenous retinal detachment (RRD) repair with pars plana vitrectomy (PPV), scleral buckle (SB), or combined SB/PPV.

Patients And Methods: A single-center, case series using Optos fundus autofluorescence (FAF) images was performed after RRD repair between April 2020 and February 2022. Retinal displacement was identified by imprinted retinal vessels on FAF imaging.

Article Synopsis
  • The study aimed to analyze sociodemographic factors in patients with eye-related issues attending emergency departments (EDs) and differentiate between emergent and nonemergent cases.
  • A total of 60,677 patients were evaluated across multiple eye hospitals throughout 2019, with findings indicating that most diagnoses were nonemergent (56.7%).
  • Key results showed that males and non-White Hispanic patients were more likely to have emergent diagnoses, while those with private insurance were less likely compared to uninsured patients; standard ED visits were associated with more emergent conditions than visits to specialized eye EDs.

Purpose: To investigate the incidence and outcomes of retinal tear (RT) and retinal detachment (RD) after cataract extraction in patients with a history of previous phakic RT.

Design: Retrospective case series.

Participants: Patients with phakic eyes with RT that were treated successfully with laser photocoagulation or cryotherapy and subsequently underwent cataract surgery.

Purpose Of Review: With a decline in the use of scleral buckling for rhegmatogenous retinal detachment (RRD) repair in recent years, this review seeks to provide a summary of the most recent research findings regarding the role of scleral buckling in the repair of RRD.

Recent Findings: Many recent studies have compared visual and anatomic outcomes between scleral buckling and pars plana vitrectomy (PPV) for RRD repair. Some suggest superior outcomes with primary scleral buckling, particularly in younger, phakic patients, and in association with other risk factors that we review.

Objective: To assess global trends in interest surrounding the newly Food and Drug Administration (FDA)-approved treatment for geographic atrophy, (GA), Syfovre (pegcetacoplan), and related searches.

Methods: We utilized Google Trends, in order to gauge the public interest in Syfovre from October 16, 2022, to October 8, 2023.

Results: Notable spikes in relative search volumes (RSV)s for "Syfovre" were observed in mid-to-late February 2023, and in March and April 2023, coinciding with the drug's FDA approval and introduction to the market.
