Purpose: To evaluate the changes in foveal avascular zone (FAZ) area and the retinal capillary density after a single intravitreal anti-VEGF injection for macular edema secondary to diabetic retinopathy or retinal vein occlusion. Methods: In this prospective noncomparative case series, 18 eyes of 15 patients with diabetic macular edema (13 eyes) or macular edema secondary to central retinal vein occlusion (5 eyes) were included. Optical coherence tomography angiography (OCTA) images were obtaine...

Purpose To investigate the structural integrity of the superficial capillary plexuses (SCPs) and deep capillary plexuses (DCPs) using optical coherence tomography (OCT) angiography (OCTA) in patients with diabetic macular edema (DME) and its association with the response to anti–vascular endothelial growth factor (VEGF) treatment. Design Retrospective, case-control study. Participants We included 51 DME eyes with a poor response to anti-VEGF agents and 32 age-matched DME eyes with a good respons...
Purpose: The aim of the study was to visualize and to quantify pathological foveal avascular zone (FAZ) alterations through optical coherence tomography angiography (OCT-A) in eyes with retinal vein occlusion (RVO) in comparison to the unaffected fellow eyes. Procedures: OCT-A was conducted with the Avanti® RTVue 100 XR system (Optovue Inc., Fremont, Calif., USA). The borders of the superficial vascular layer (SVL) were defined as 3 μm below the internal limiting membrane and 15 μm below the inn...
To analyze the characteristics and the course of macular edema secondary to central retinal vein occlusion (CRVO) using optical coherence tomography (OCT) and to determine correlations between clinical, tomographic and angiographic data, in particular including retinal ischemia. In this retrospective study, 53 consecutive patients with CRVO were included. At each follow-up visit, patients underwent complete ophthalmological examination, including best-corrected visual acuity (BCVA) and OCT. Fluo...
The aim of the chapter is to provide a practical but exhaustive guide in detecting macular edema and to describe its features depending on the retinal condition which cause it. The most useful imaging

Objective To describe the natural history of central retinal vein occlusion (CRVO) based on the best available evidence from the literature. Clinical Relevance Central retinal vein occlusion is a common sight-threatening retinal vascular disease. Despite the introduction of new interventions, the natural history of CRVO is unclear. Methods Systemic review of all English language articles retrieved using a keyword search of MEDLINE, EMBASE, Current Contents, and the Cochrane Library to November 1...
Purpose: The aim of this study was to describe a case of angiographically documented foveal avascular zone (FAZ) enlargement after intravitreal bevacizumab following vitrectomy and intravitreal bevacizumab treatment of a diabetic patient.Methods: This study was done as a case report.Results: A 40-year-old diabetic man was treated with a pars plana vitrectomy and intravitreal bevacizumab for a nonclearing vitreous hemorrhage. Despite successful surgery, the postoperative best-corrected visual acu...
Purpose : We compared the perifoveal capillary ring state and the size of the macular ischemic area in patients with the macular edema, then analyzed the effect of grid photocoagulation on macular edema. The aim of the present study was to evaluate visual prognosis and to determine treatment modality of macular edema with macular ischemia in branch retinal vein occlusion (BRVO). Methods : We did retrospective clinical analysis on the macular edema and macular circulatory state using clinical rec...

Abstract PURPOSE: To describe the causes of and risk factors for persistent severe visual loss occurring in the Early Treatment Diabetic Retinopathy Study (ETDRS). METHODS: The ETDRS was a randomized clinical trial investigating photocoagulation and aspirin in 3,711 persons with mild to severe nonproliferative or early proliferative diabetic retinopathy. Severe visual loss, defined as best-corrected visual acuity of less than 5/200 on at least two consecutive 4-month follow-up visits, developed ...

Objective: To assess the perifoveal microcirculation in diabetic maculopathy without clinically significant macular edema and its relationship to visual acuity. Design: Prospective analysis. Setting: A teaching hospital. Patients: Fifteen patients with impaired visual acuity of 20/50 or worse, a diabetic control population with unaffected visual acuity (matched age, gender, retinopathy stage), and 52 healthy controls were enrolled. Interventions: Study consisted of video-fluorescein angiography ...
