Prospective, randomized, comparative, and controlled study to estimate the association between angle distance and higher-order aberrations (HOAs) with postoperative visual acuity after presbyopia-correcting IOL implantation. Forty-three eyes from 43 patients were included and randomly assigned in two groups for either AT LISA tri 839MP or Acrysof IQ PanOptix IOL implantation. The OPD-Scan III analyzer was utilized to assess the angle distance and higher-order aberration (HOAs). Twenty-three eyes were in the Acrysof IQ PanOptix group and 20 patients in the AT LISA tri 839MP group. The uncorrected distance visual acuity (UDVA) for the PanOptix group was 0.092 ± 0.10, whereas for AT LISA tri was 0.050 ± 0.06 (=0.229). The uncorrected intermediate visual acuity (UIVA) for the PanOptix group was 0.173 ± 0.18, whereas for AT LISA tri, it was 0.182 ± 0.11 (=0.669). Uncorrected near visual acuity (UNVA) was 0.068 ± 0.04 and 0.085 ± 0.07, respectively (=0.221). Also, correlation coefficient between HOAs and the Strehl ratio for each group were -0.768 ( < 0.0001) and -0.863 (=0.0001). Patients implanted with both trifocal IOLs showed excellent postoperative visual performance at all distances at the six-month follow-up visit. No association was found between angle distance and postoperative visual acuity regardless of the angle magnitude or the two trifocal IOLs inner optical diameter. Also, internal aberrations demonstrated a significant inverse correlation with the Strehl ratio for both trifocal IOLs.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
Methods: This is a retrospective interventional case report.

Purpose: To quantitatively explore preretinal abnormal tissue (PAT) in macula-on rhegmatogenous retinal detachment (RRD) before and after surgery.
Methods: In this case-series study, PAT was detected by en-face optical coherence tomography images with custom slabs in eyes that underwent pars plana vitrectomy and SF6 for macula-on RRD.Main outcome measures were PAT area at baseline, 3-month and 6-month follow-up, and its relative change.
Purpose: Proliferative vitreoretinopathy (PVR) is the leading cause of surgical failure following rhegmatogenous retinal detachment (RRD). In this study, we aimed to explore ocular and systemic risk factors for PVR due to RRD in a large patient database.
Methods: Patients who have a diagnosis of RRD and PVR, and who have been seen in the last seven years prior to analysis (January 2015-February 2023) were identified in the Vestrum Health database.

Purpose: To report the clinical presentation, treatment course, and outcome of a case of bilateral frosted branch angiitis (FBA) and neuroretinitis associated with acute Epstein-Barr virus (EBV) infection in a pediatric patient with Turner Syndrome.
Methods: Case report with multimodal ocular imaging and extensive systemic workup.
Results: A 16-year-old female with Turner syndrome presented with acute bilateral vision loss, hearing loss, and ataxia.

Purpose: To describe two cases of pediatric patients with Coats disease who developed nerve fiber layer (NFL) schisis.
Methods: Observational case series.
Results: Two male pediatric patients, ages 2 and 14, who were being treated for Coats disease were found to have NFL schisis on optical coherence tomography.
