Pigment epithelial detachment

Retinal pigment epithelium (RPE) tears occur when the RPE acutely breaks and retracts, leaving the underlying Bruch's membrane and choroid exposed. They usually happen in areas of previous pigment epithelial detachments and are generally associated with age-related macular degeneration (AMD). The purpose of this report is to describe a case of a spontaneous massive central RPE tear in a patient with untreated AMD. A 67-year-old female patient presented with complaints of sudden decreased vision in her right eye...

Background and objectives Over the years, several treatment options have been developed for neovascular age-related macular degeneration (AMD), the most notable being intravitreal injections of anti-vascular endothelial growth factor drugs. The rationale for treating neovascular AMD is to preserve and improve central vision, enhance the quality of life for affected individuals, stabilize or improve vision, and prevent further structural damage to the macula. The objective of the present study was to evaluate the clinical course of different disease types of neovascular age-related macular degeneration and their treatment response to anti-vascular endothelial growth factor (anti-VEGF) injections...

PURPOSE: To evaluate the genetic associations of different subtypes of central serous chorioretinopathy (CSCR), neovascular age-related macular degeneration (nAMD), and polypoidal choroidal vasculopathy (PCV). DESIGN: A case-control genetic association study. METHODS: This study enrolled 217 CSCR, 341 nAMD, 288 PCV patients, and 1380 controls. The CSCR patients were classified into those with focal or diffuse leakage, with or without pigment epithelial detachment (PED), and with or without macular neovascularization (MNV)...

Central serous chorioretinopathy (CSC) is the buildup of fluid in the posterior pole distorting the vision resulting from either neurosensory or retinal pigment epithelial detachment. This is a case report of a 33-year-old female complaining of cloudiness in the left eye who was subsequently diagnosed with CSC using optical coherence tomography (OCT). Remission was observed in four months, possibly from ocular drop treatment or spontaneous. Our case report is unique as the incidence of CSC is more common in males, almost six times higher than in females...

PURPOSE: To examine the associations between the vortex vein characteristics and locations of the pigment epithelial detachment (PED) and leak point in patients with central serous chorioretinopathy (CSC). DESIGN: Observational case series. METHODS: We evaluated 116 eyes of 104 patients with CSC. The PED and leak point locations were superimposed over the choroidal en face images using widefield swept-source optical coherence tomography and fluorescein angiography...

To report long-term outcomes of brolucizumab in neovascular age-related macular degeneration (nAMD) treatment. Records from 74 patients were retrospectively reviewed. Both naïve eyes and those previously treated with other antiVEGF agents were included. Primary outcomes included variation in best corrected visual acuity (BCVA), central subfield thickness (CST), intraretinal fluid (IRF), subretinal fluid (SRF), and pigment epithelial detachment (PED) dimensions. Outcomes were reviewed after the loading phase, at week 24, and at last follow-up...

OBJECTIVE: To analyze the presence and morphologic characteristics of drusenoid pigment epithelial detachments (DPEDs) in spectral-domain optical coherence tomography (SD-OCT) in Caucasian patients with early and intermediate age-related macular degeneration (AMD) as well as the influence of these characteristics on best-corrected visual acuity (BCVA) and disease progression.
