PURPOSE: To determine the size of the superficial foveal avascular zone (FAZ) by optical coherence tomography angiography before and after surgery for an idiopathic macular hole. METHODS: A retrospective, observational case series, in which 16 eyes of 16 patients with an idiopathic macular hole were studied. Pars plana vitrectomy was performed with internal limiting membrane peeling. The foveal retinal vasculature was examined by optical coherence tomography angiography, and the area of the superficial FAZ was determined before, and at 1 and 3 months after the surgery...

PURPOSE: To quantitatively assess macular morphology and perfusion status using optical coherence tomography, and optical coherence tomography angiography in eyes with branch retinal vein occlusion when macular edema has completely resolved, and to investigate the impact on visual function. METHODS: Thirty consecutive eyes with branch retinal vein occlusion-macular edema that resolved after treatment with intravitreal ranibizumab injections were included. Macular sensitivity was measured by microperimetry; defect length of foveal ellipsoid zone band was measured using optical coherence tomography; foveal avascular zone and parafoveal nonperfusion areas (NPA) were measured by optical coherence tomography angiography...

We investigated retinal structure and function in eyes with optic nerve hypoplasia (ONH). Twenty-nine eyes of 18 patients with ONH and 21 eyes of 21 control patients were analyzed. Spectral-domain optical coherence tomography (SD-OCT), full-field electroretinography (FF-ERG), and focal macular ERG (FM-ERG) were performed. SD-OCT analysis of the macular region showed significant ganglion cells complex (GCC) thinning nasally and temporally (P < 0.05), but the thickness from the inner nuclear layer (INL) to the retinal pigment epithelium (RPE) became thinner only nasally (P < 0...

PURPOSE: To compare aqueous angiogenic and inflammatory cytokine concentrations in different patterns of diabetic macular edema (DME) based on optical coherence tomography (OCT). METHODS: This prospective study was conducted between July 1, 2015, and March 31, 2016, for 9 months. Aqueous samples were obtained from 52 consecutive DME patients and 16 controls. DME patients were divided according to OCT patterns into diffuse retinal thickening (DRT; n = 17), cystoid macular edema (CME; n = 20) and serous retinal detachment (SRD; n = 15) groups...

Importance: The early decline and recovery of retinal structure and function following iatrogenic macular detachment for retinal gene therapy is not well characterized in those with relatively preserved central visual function. Here, the recovery of retinal structure and function over the first month following iatrogenic retinal detachment for the delivery of adeno-associated viral vector encoding Rab Escort Protein 1 is described as a part of gene therapy for choroideremia. Objective: To study changes in both retinal structure and function during the first month following iatrogenic macular detachment surgery...

PURPOSE: Congenital achromatopsia is an autosomal recessive disease causing substantial reduction or complete absence of cone function. Although believed to be a relatively stationary disorder, questions remain regarding the stability of cone structure over time. In this study, the authors sought to assess the repeatability of and examine longitudinal changes in measurements of central cone structure in patients with achromatopsia. METHODS: Forty-one subjects with CNGB3-associated achromatopsia were imaged over a period of between 6 and 26 months using optical coherence tomography and adaptive optics scanning light ophthalmoscopy...

PURPOSE: To evaluate the effects of the subthreshold laser treatment as a therapeutic option in the treatment of serous retinal detachment secondary to dome-shaped macula. METHODS: Prospective pilot study with 12-month follow-up. Each patient underwent a complete ophthalmologic examination, including best-corrected visual acuity, fluorescein angiography, indocyanine green angiography, and spectral domain optical coherence tomography. Eyes with persistent serous retinal detachment lasting for a minimum of 12 months and absence of best-corrected visual acuity improvement underwent subthreshold laser treatment in a single session...

Purpose: We evaluate the expression of Gli1 in human epiretinal membranes (ERM) and correlate this with clinical data. Methods: We prospectively recruited patients with ERM. A total of 33 human ERM specimens were immunolabeled with anti-Gli1 antibody and the number of total cells/hyperfield (HF), Gli1(+) cells/HF, and the percentage of Gli1(+) cells/total cells were calculated. We evaluated the interrelationship of cellular properties and clinical findings, such as presence of diabetic retinopathy (DR), retinal breaks, intraocular inflammation, central foveal thickness, maximal retinal thickness, retinal contraction, lamellar holes, pseudoholes, the attenuation or absence of an inner segment/outer segment (IS/OS) junction/external limiting membrane (ELM), cystic changes, and paravascular inner retinal defects...

PURPOSE: To show the prognostic value of foveal microstructures using optical coherence tomography (OCT) for the restoration of inner segment/outer segment (IS/OS) junction layer following resolution of diabetic macular edema (DME). METHODS: Forty-one eyes of 39 patients with IS/OS damage at the time of DME that showed complete resolution of DME were included. Eyes were divided into 2 groups based on the IS/OS integrity at final visit, when edema was completely resolved: always damage group (damage at baseline and at final visit) and initial damage group (damage only at baseline)...
