PURPOSE: To evaluate the effect of epiretinal membranes (ERMs), detected with spectral-domain optical coherence tomography (SD-OCT), on the outcome of antivascular endothelial growth factor (VEGF) treatment for neovascular age-related macular degeneration (nAMD). METHODS: A total of 434 eyes with treatment-naive nAMD were retrospectively included and analyzed. All patients were administered an initial series of 3 monthly loading injections of ranibizumab or aflibercept, followed by further injections as required...

OBJECTIVE: To analyse macular retinal and choroidal layer thickness in former preterm and full-term infants and to assess associated perinatal influence factors and functional correlation. METHODS: This prospective controlled, cross-sectional, hospital-based study in a tertiary center of maximum care examined former preterm infants with a gestational age (GA) ≤ 32 weeks and full-term neonates currently aged 4 to 10 years. We investigated data from 397 infants, analysing total foveal retinal thickness and six distinct macular retinal layer and choroidal layer measurements via spectral-domain optical coherence tomography...

PURPOSE: To report the findings in three cases in which the average foveal thickness was increased after a thin epiretinal membrane (ERM) was removed by vitrectomy with internal limiting membrane (ILM) peeling. METHODS: The foveal contour was normal preoperatively in all eyes. All cases underwent successful phacovitrectomy with ILM peeling for a thin ERM. The optical coherence tomography (OCT) images were examined before and after the surgery. The changes in the average foveal (1 mm) thickness and the foveal areas within 500 μm from the foveal center were measured...

Intravitreal ranibizumab (RBZ) has been shown in multiple randomized clinical trials to be a valuable treatment for diabetic macular edema (DME), promoting a significant improvement in best-corrected visual acuity (BCVA) and in anatomic outcomes. Compared to sham (RISE and RIDE studies), RBZ rapidly and sustainably improved BCVA and decreased macular edema at 2 years, reducing the risk of further vision loss, with low rates of local or systemic side effects. Compared to macular laser photocoagulation (READ-2 study), RBZ provided a greater improvement in BCVA and regression in foveal thickness, but required a higher number of injections compared to patients treated with both RBZ and laser...

PURPOSE: To evaluate the safety and efficacy of selective retina therapy (SRT) with real-time feedback-controlled dosimetry (RFD) in the treatment of chronic central serous chorioretinopathy (CSC). METHODS: In this retrospective case series study, 50 eyes of 49 patients with chronic CSC demonstrating focal or diffuse foveal leakages on fundus fluorescein angiography (FFA) were included. Following evaluation of test spots at temporal arcades, SRT (wavelength 527 nm, pulse repetition rate 100 Hz, pulse energy ramp with maximal 15 pulses) with retinal spot diameter of 200 μm was applied to the areas of each leakage observed on fluorescein angiography...

We studied the clinical efficacy of Bevacizumab combined with argon green laser in treating fundus macular edema. From May 2009 to April 2013, 78 patients seeking treatment for macular edema in the First Affiliated Hospital of Nanchang University were enrolled in this study. Patients were randomly divided into two groups: i) The experimental group (n=39) and the control group (n=39). Patients in the experimental group were treated with Bevacizumab (Avastin(®)) combined with argon green laser, and those in the control group were treated exclusively with argon green laser...

Ophthalmologists sometimes face difficulties in identifying the origin of visual acuity (VA) loss in a retinitis pigmentosa (RP) patient, particularly before cataract surgery: cataract or the retinal disease state. Therefore, it is important to identify the significant factors correlating with VA. Nowadays, retinal blood flow in superficial and deep layers can be estimated non-invasively using optical coherence tomography angiography (OCTA). We estimated blood flow per retinal layer by using OCTA; investigated the correlation between VA and other parameters including blood flow and retinal thickness; and identified the most associated factor with VA in patients with RP...

BACKGROUND: To evaluate macular changes in fellow eyes of patients diagnosed with lamellar macular hole (LMH) using spectral-domain optical coherence tomography (SD-OCT) and blue fundus autofluorescence (B-FAF). METHODS: Fellow eyes of patients diagnosed with a LMH were retrospectively evaluated on OCT. Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were recorded. Corresponding B-FAF images, vitreo-macular relations, and type of epiretinal membranes (ERMs) were also examined...

Fluorescein angiography has been so far the gold-standard test to assess diabetic macular ischemia (DMI), a cause of irreversible visual impairment in diabetic patients. The aim of this study was to investigate foveal avascular zone (FAZ) and perifoveal microcirculation changes in eyes with nonproliferative diabetic retinopathy (NPDR) using optical coherence tomography angiography (OCTA), a new and noninvasive vascular imaging technique.Cross-sectional study including eyes of diabetic patients with NPDR.All patients underwent medical history, best-corrected visual acuity (BCVA) measurement, slit-lamp and fundus examination, multicolor imaging, SD-OCT, and swept-source OCT...
