Abstract This multicenter study aimed to assess the short-term effectiveness and safety of faricimab in treatment-naïve patients with wet age-related macular degeneration (wAMD) Japan. We retrospectively reviewed 63 eyes 61 wAMD, including types 1, 2, 3 neovascularization as well polypoidal choroidal vasculopathy (PCV). Patients received three consecutive monthly intravitreal injections loading therapy. Over these months, visual acuity improved gradually compared baseline. Moreover, central...

To report a case of intraocular inflammation (IOI) after intravitreal injection aflibercept 8 mg for treatment-refractory neovascular age-related macular degeneration. An 80-year-old man with diabetes mellitus had degeneration refractory to treatment 2 mg. Despite ten injections faricimab, the exudation remained, and we switched brolucizumab, which resulted in mild IOI. The IOI improved only topical steroids, back exudation. However, decided switch careful discussion patient. Two weeks...

Abstract This multicentre retrospective study evaluated the 1-year outcomes and safety profile of faricimab in treatment-naïve patients with neovascular age-related macular degeneration (nAMD). Fifty-five (57 eyes) underwent loading therapy comprising three monthly injections. If dryness was achieved by third month, subsequent treat-and-extend (TAE) follow-up continued at a minimum 8-week interval thereafter. wet macula persisted fourth dose administered, followed TAE regimen. After 1 year,...

To examine the foveal structure and vasculature in eyes with an idiopathic epiretinal membrane (ERM).Forty-nine of 48 patients ERM were studied. The superficial avascular zone (FAZ) was measured by optical coherence tomography angiography (OCTA; RTVue XR Avanti, Optovue Inc., Fremont, CA), central thickness (CFT) swept source OCT (DRI-OCT, Topcon, Japan). Twenty underwent vitrectomy internal limiting (ILM) peeling, FAZ CFT evaluated pre- postoperatively. Forty-nine 49 age-matched healthy...

To determine whether a significant correlation exists between the presence of bulge in photoreceptor inner segment/outer segment line and best-corrected visual acuity eyes after successful rhegmatogenous retinal detachment (RRD) repair.Patients who had undergone RRD repair an intact at central fovea spectral-domain optical coherence tomographic images were retrospectively studied. Thirty-five 35 patients evaluated, classified preoperatively into those with macula-on (n = 14) macula-off 21)....

Purpose: To evaluate the foveal granular reflexes (Jampol dots) in macula with multiple evanescent white dot syndrome (MEWDS) and describe pathophysiology. Methods: Eighteen eyes of 18 MEWDS cases (4 male,14 female) were studied. We evaluated presence location Jampol dots classified them into micro fused types based on fundus appearance, mixed type was included type. The findings optical coherence tomography (OCT) en face OCT investigated. A normal also analyzed. Results: seen (83%) 15 eyes:...
