BACKGROUND Macular telangiectasia type 2 (MacTel 2) is a bilateral idiopathic, rare neurodegenerative disease with alterations in the macular capillary network leading to vision loss and is the most common of three subtypes. Optical coherence tomography angiography (OCTA) is a non-invasive imaging modality which helps understand the complex pathological(More)
PURPOSE To evaluate a fully automated local fractal dimension method to quantify vessel density and foveal avascular zone (FAZ) area in optical coherence tomography angiography (OCTA) images. METHODS Fifty-two healthy Asian Indian eyes underwent imaging prospectively with OCTA system. Superficial and deep retinal vascular plexus was imaged. Local fractal(More)
PURPOSE To correlate retinal vascular features with severity and systemic indicators of diabetic retinopathy (DR) using optical coherence tomography angiography (OCTA). METHODS A total of 209 eyes of 122 type 2 diabetes mellitus patients with DR and 60 eyes of 31 normal Indian subjects underwent OCTA imaging. The diabetic retinopathy patients were graded(More)
We describe the use of optical coherence tomography angiography (OCTA) in detecting and monitoring regression of the neovascular complex (NVC) in a case of aggressive posterior retinopathy of prematurity (AP-ROP). A premature Asian Indian girl with AP-ROP underwent laser photoablation at 26 days of life. Persistent NVC at the posterior border of the lasered(More)
PURPOSE To describe the correlation between the surface morphology on spectral-domain optical coherence tomography (SD-OCT) and leakage pattern on fundus fluorescein angiography (FFA) in an infant with multiple retinal hamartomas. METHODS An Asian Indian female infant was found to have 2 retinal lesions in the right eye and 1 in the left eye during Retcam(More)
PURPOSE To study whether there exists a relationship between retinal nerve fiber layer thickness and oxygen saturation and to identify whether perivascular thickness (pRNFL) or quadrant thickness (qRNFL) has a stronger correlation. METHODS Patients without any detectable ocular abnormality on complete ophthalmic evaluation underwent non-invasive(More)
PURPOSE To evaluate the safety and efficacy of intravitreal diclofenac sodium. METHODS A 61-year-old male with persistent diabetic macular edema was treated with 450 μg of intravitreal diclofenac sodium (systemic preparation). RESULTS Postinjection Day 1, the spectral domain optical coherence tomography showed irregular vitreoretinal interface with(More)
In this observational and cross-sectional study, capillary nonperfusion (CNP) and vascular changes in branch retinal vein occlusion (BRVO, sample size [n] = 26) and choroidal neovascularization (CNV, n = 29) were evaluated. Subjects underwent imaging using Optical coherence tomography angiography (Angiovue OCTA, RTVue XR, Optovue Inc., Fremont, California).(More)
