Visual acuity (VA) is a traditional measure of central visual function, particularly the ability of the eye to perceive details. In a clinical setting, standardized charts are commonly used to quickly assess VA. Namely, the Early Treatment of Diabetic Retinopathy Study (ETDRS) VA test chart is the gold standard for VA testing in the clinical setting. This chapter outlines the standard procedures associated with measuring VA.

Analysis of quantitative OCT and SS-OCTA metrics three months after initiation of intravitreal faricimab for treatment-recalcitrant neovascular AMD.

Purpose: To utilize optical coherence tomography (OCT) and SS-OCT angiography (SS-OCTA) for quantifying morphological changes seen in eyes with recalcitrant neovascular age-related macular degeneration (nAMD) transitioned to intravitreal faricimab injections during the manufacturer's recommended induction phase of treatment.
Methods: Fifty-four treatment-recalcitrant patients (60 eyes) were recruited. OCT and SS-OCTA images were obtained at 0 and 3 months.
1-Year real-world outcomes of faricimab in previously treated neovascular age-related macular degeneration.

Background And Objectives: Faricimab, a bispecific antibody targeting VEGF-A and angiopoietin-2, has shown promise in treating neovascular age-related macular degeneration (nAMD). This study evaluates 1-year outcomes of faricimab in treatment-experienced nAMD patients.
Methods: This single-centre retrospective cohort study included patients previously treated for nAMD who switched to faricimab between November 2022 and March 2024.
Poor fixation stability does not account for motion perception deficits in amblyopia.

People with amblyopia show deficits in global motion perception, especially at slow speeds. These observers are also known to have unstable fixation when viewing stationary fixation targets, relative to healthy controls. It is possible that poor fixation stability during motion viewing interferes with the fidelity of the input to motion-sensitive neurons in visual cortex.

Because of its benign nature and rarity, circumscribed choroidal hemangioma (CCH) often receives limited attention, leading to a high rate of misdiagnosis and a lack of standardized treatment protocols. We provide a thorough clarification of the demographics, clinical features, diagnosis, management, and prognosis of CCH. We conducted a systematic search of the PubMed, EMBASE, and Ovid databases up to December, 2023, to identify relevant studies.

Background/objectives: The visual acuity (VA) outcomes after the first and second years of anti-vascular endothelial growth factor (anti-VEGF) treatment in patients with diabetic macular oedema (DMO) were evaluated, and the factors associated with treatment success were investigated.
Methods: Using Medisoft electronic medical records (UK), this retrospective cohort study analysed VA outcomes, changes, and determinants in DMO patients at year 1 and year 2 after initial anti-VEGF injection. Descriptive analysis examined baseline demographics and clinical characteristics, while regression models were used to assess associations between these factors and changes in VA.
