OBJECTIVE: Diabetic macular edema (DME) is one of the most important sight-threatening complications in patients with diabetes. Due to neuroprotective properties, crocin, as the main constituent in saffron, is thought to be useful in the treatment and prevention of diabetic maculopathy. The aim of this trial was to evaluate the effects of crocin as a supplement on reducing inflammation in patients with diabetic maculopathy. DESIGN: Double blind, placebo controlled, phase 2 randomized clinical trial...

PURPOSE: The purpose of the study is to investigate the correlation between intraocular anti-retinal antibodies and clinical measurements in patients with rhegmatogenous retinal detachment (RRD) and proliferative vitreoretinopathy (PVR). MATERIAL AND METHODS: Aqueous humor and vitreous samples were collected from patients with RRD, PVR, and from control subjects with macular hole. The levels of total protein (TP), IgG, and anti-retinal antibodies were determined with a bicinchoninic acid assay, enzyme-linked immunosorbent assay, and dot blot, respectively...

PURPOSE: To examine frequency and associations of retinal hemorrhages. METHODS: The population-based Beijing Eye Study included 3,468 individuals. Monoscopic fundus photographs were examined for hemorrhages. RESULTS: Retinal hemorrhages were detected in 515 eyes (429 individuals) (prevalence: 7.6%; 95% confidence interval [CI]: 7.0-8.0 per eye; 12.7%; 95% CI: 11.7-13.7 per person). Higher prevalence of retinal hemorrhages was correlated (multivariate analysis) with higher systolic blood pressure (P < 0...

PURPOSE: To present a case of crystalline retinopathy associated with chronic retinal detachment and localize the macular crystals using spectral domain optical coherence tomography. METHODS: Case Report. RESULTS: A 37-year-old man with previously treated chronic retinal detachment presented with normal vision and crystalline maculopathy. Spectral domain optical coherence tomography localized the macular crystals to the posterior hyaloid membrane and on the internal limiting membrane, but not within the retina...

INTRODUCTION: Antimalarial drugs are largely used for the treatment of various systemic diseases. They can cause toxic retinopathy, which can lead to blindness. OBSERVATION: We report the case of a 32-year-old male with a systemic lupus erythematosus treated with hydroxychloroquine 400mg per day and then chloroquine 300mg per day during 8 and 9years respectively. Eighteen months after his latest visual examination, the patient experienced bilateral vision loss. Fundus examination revealed a bull's eye maculopathy...

PURPOSE: To identify systemic risk factors for sickle cell maculopathy, and to analyze the microstructure of the macula of Sickle Cell Disease (SCD) patients by using automated segmentation of individual retinal layers. METHODS: Thirty consecutive patients with SCD and 30 matched controls underwent spectral-domain optical coherence tomography (SD-OCT) and automated thickness measurement for each retinal layer; thicknesses for SCD patients were then compared to normal controls...

Objective: To evaluate macular choroidal thickness (CT) and retinal thickness in Turkish patients with high myopia without maculopathy and in normal subjects and to examine the association with age, axial length (AL), best corrected visual acuity (BCVA), cycloplegic refraction, and spherical equivalent (SE). Methods: This prospective study was performed between January 2015 and June 2016 in the Department of Ophthalmology, Duzce University Medical Faculty. It had 65 individuals (30 patients with high myopia, 35 healthy subjects)...

Objective: To investigate the manifestation characteristics of fundus fluorescence angiography (FFA) and its values in diagnosing diabetic retinopathy through comparing direct ophthalmoscopy. Methods: Two hundred fifty patients (500 eyes) who were suspected as diabetic retinopathy and admitted to the hospital between February 2015 and December 2016 were selected. They underwent direct ophthalmoscopy and FFA. The manifestation characteristics of FFA in the diagnosis of diabetic retinopathy were summarized...

Diabetic retinopathy (DR) is a well-known risk factor in the development of radiation maculopathy (RM). Steroids have been shown to improve the vision and reduce the macular thickness in patients with RM. This observational case report highlights altered course of DR after a course of radiotherapy for orbital lymphoma, after a single dose of intravitreal dexamethasone implant showed a dramatic revascularization of the ischemic macula, with a significant reduction in the size of ischemic area. This appears to be the first case in literature corroborating the favorable effect on steroids on retinal vasculature, seen angiographically...

PURPOSE: To analyze morphologic and functional changes after inverted internal limiting membrane-flap technique for optic disk pit maculopathy using optical coherence tomography, multifocal electroretinography, and microperimetry. METHODS: One case report. RESULTS: A 30-year-old woman presented us with decreased visual acuity (20/63) in the left eye because of retinoschisis and serous macular detachment associated with optic disk pit. Optical coherence tomography did not localize the source of intraretinal and subretinal fluid...

Purpose: To report retinal findings in two patients with mucopolysaccharidosis type I (MPS I) receiving human recombinant alpha-l-iduronidase (Laronidase) as enzyme replacement therapy. Observations: Patient 1 had visual acuity 20/20 right eye, 20/25 left eye and unremarkable anterior segment and retinal examination. Optical coherence tomography (OCT) scanning demonstrated parafoveal thinning and subfoveal hyperreflectant material. Patient 2 had visual acuity 20/20 both eyes, with dense nuclear cataract both eyes...

Dengue fever is common in the tropics and its clinical manifestations and complications are well-known. However, dengue-related ocular complications are rare. Here we present a postpartum female who complained of bilateral central scotoma, at five days after the clinical diagnosis of dengue fever. The ocular examination was suggestive of dengue maculopathy and foveolitis. She was treated with a combination of intravenous methylprednisolone and immunoglobulin. The final visual recovery was good.

CASE REPORT: A 36-year-old man went to the emergency department the day after exposure to a laser pointer. Funduscopy revealed dispersed macular pigment alterations, and optical coherence tomography showed a disruption of the retinal layers. The visual acuity was counting fingers in both eyes. Nine months later, optical coherence tomography angiography showed a rarefaction in the choriocapillaris vascular flow in the area of the laser injuries. DISCUSSION: The retinal layer mainly damaged by the laser injury was the retinal pigment epithelium...

BACKGROUND/AIMS: Age-related macular degeneration (AMD) is estimated to affect 196 million people >50 years old globally. Prevalence of AMD-associated genetic risk factors and rate of disease progression are unknown in Ireland. METHODS: Prevalence of AMD-associated genetic risk variants, complement factor H (CFH) rs1061170, age-related maculopathy susceptibility 2 (ARMS2) rs10490924, component 3 (C3) rs2230199, complement factor B (CFB) rs641153 and superkiller viralicidic activity 2-like (SKIV2L) rs429608 and 4-year progression data in a population-representative cohort (The Irish Longitudinal study on Ageing (TILDA)) were assessed...

PURPOSE: To present a series of idiopathic paracentral acute middle maculopathy (PAMM) and acute macular neuroretinopathy (AMN) cases and to compare the microvascular retinal status of PAMM/AMN eyes with those of healthy individuals. METHODS: Six eyes with PAMM and two eyes with AMN in a total of six patients were included in this study. Multimodal retinal imaging, including optical coherence tomography angiography, was performed in all patients. The vessel density of the superficial capillary plexus and deep capillary plexus, as well as the area, circularity, and angle of the superficial foveal avascular zone (FAZ) were measured and compared with the same parameters in age-matched healthy individuals...

This case report aims to study active cone regeneration and its functional correlation in optic disc pit maculopathy (ODPM) with a large outer macular defect treated with autologous internal limiting membrane (ILM) "chunk" transplantation. Outcome analysis was done using spectral-domain optical coherence tomography (SD-OCT), adaptive optics, and microperimetry. Visual acuity improved from counting fingers at 2 meters to 6/18 Snellen equivalent postoperatively, whereas SD-OCT demonstrated closure of outer subfoveal defect...
