Purpose: To demonstrate the importance of optical coherence tomography (OCT) in identifying macular changes not detected at clinical examination preceding cataract surgery in patients older than 60 years.
Setting: Hospital Oftalmológico Visão Laser, Santos, São Paulo, Brazil.
Desing: Prospective case series.
Methods: Patients older than 60 years were selected for this cross-sectional prospective study conducted during preoperative examination for cataract surgery. Eyes with a previous diagnosis or clinical evidence of macular disease or with media opacity preventing OCT from being performed were excluded from the study. All the study participants underwent OCT and were then divided into 2 groups: patients with macular changes and patients without macular changes found on OCT.
Results: Of 364 eyes screened (212 patients), 300 eyes (180 patients) were included in the study. OCT identified macular changes in 40 eyes (13.3%), with age-related macular degeneration being found in 13 eyes (4.3%), epiretinal membrane in 12 eyes (4%), intraretinal fluid in 12 eyes (4%), and macular hole in 3 eyes (1%). In the group with macular changes, the mean age was 74.4 ± 6.3 years compared with 70.4 ± 6.7 years for those without changes ( P < .001).
Conclusions: OCT proved an effective method for identifying macular diseases not detected at clinical evaluation before cataract surgery. Therefore, the relevance of performing OCT in these cases was confirmed and should be taken into consideration, particularly when evaluating patients older than 60 years.

Background: We aimed to describe a 2-year outcome of eyes managed by practitioners benchmarked using a funnel plot by their frequency of treatment using vascular endothelial growth factor (VEGF) inhibitors for naive retinal vein occlusion (RVO).
Methods: A multicentre, international, observational study of 29 doctors in 12 countries managing 1110 eyes with RVO commencing VEGF inhibitors between 1 January 2012-2022 tracked in the Fight Retinal Blindness! registry.
Results: We identified 3 outlying 'intensive' practitioners (managing 350/1110 eyes [32%]), 22 'typical' practitioners (604/1110, [54%]) and 4 outlying 'relaxed' practitioners (156/1110, [14%]) with respective 24-month outcomes in Branch and Central RVO including the primary outcome, mean adjusted change in visual acuity (VA) in BRVO: +16.
[Peripapillary pachychoroid syndrome].

Peripapillary pachychoroid syndrome (PPS) is a recently described condition, classified within the pachychoroid disease spectrum characterized by focal or diffuse thickening of the choroid due to dilation of choroidal vessels in the Haller's layer (pachyvessels), thinning of the choriocapillaris and the Sattler's layer, and accompanied by increased choroidal permeability and damage to the retinal pigment epithelium. Unlike other pachychoroid diseases that involve changes in the central retina, PPS presents with choroidal thickening and intra- or subretinal fluid located nasally in the macular region, near the optic disc. This review aims to summarize and analyze current data on the clinical features, pathogenesis, and treatment options for PPS found in the literature.

Purpose: This study presents an indirect comparison of the effectiveness and safety of faricimab versus other treatment options for DME.
Purpose: This study evaluates the efficacy of intravitreal injections (IVI) of faricimab in patients with neovascular age-related macular degeneration (nAMD) and retinal pigment epithelium detachment (RPED) resistant to other anti-VEGF agents.
Material And Methods: The study included 61 patients (61 eyes) with nAMD previously treated with aflibercept and/or brolucizumab IVIs. Three groups were formed: group 1 received aflibercept IVI (32 eyes), group 2 received brolucizumab IVI (14 eyes), and group 3 received aflibercept followed by brolucizumab IVI (15 eyes).

We compared chorioretinal microvascular of Slow Coronary Flow Phenomenon (SCFP) patients using Optical Coherence Tomography Angiography (OCTA) to healthy controls. We recruited 21 patients from September 2023 until January 2024 from two referral centers. We enrolled 21 age-sex-matched controls retrospectively.
