BACKGROUND/PURPOSE: To evaluate the occurrence and characteristics of outer retinal tubulation (ORT) in an Indian population with retinal dystrophies. METHODS: In this retrospective study, 309 eyes of 157 patients with retinal dystrophies including retinitis pigmentosa (RP, 183 eyes), Stargardt disease (STGD, 93 eyes) and Best disease (33 eyes) were reviewed. The demographic details, clinical data including visual acuity, treatment history and good quality spectral domain optical coherence tomography (SD-OCT) scans were collected...

PURPOSE: The advent of spectral domain optical coherence tomography has led to superb imaging capabilities in addition to enhanced visualization of the retinal layers. Such advancements have led to the identification of a variety of new retinal conditions, including outer retinal tubulations (ORTs). ORTs are ovoid hyporeflective spaces located in the outer retina. The pathogenesis is unclear but seems to involve sublethal injury to the photoreceptors leading to a compensatory reorganization of the photoreceptor layer with the neighboring ellipsoid zone resulting in a hyperreflective border surrounding a central lumen...

PURPOSE: To evaluate the anterior lamina cribrosa (LC) surface tilt angle in myopic eyes and associate it with glaucoma development. MATERIALS AND METHODS: In this retrospective study, medical records of myopic patients referred for glaucoma examination from July 1, 2012 to March 30, 2016 were reviewed. Comprehensive ophthalmic examination including spectral-domain optical coherence tomography were performed. We measured the angle of anterior LC surface tilt against Bruch's membrane opening from optical coherence tomography images at the center of the clinical optic disc margin...

PURPOSE: The objective of this study was to compare the anatomical and functional outcomes of ranibizumab versus aflibercept for the treatment of macular edema due to central retinal vein occlusion (CRVO) in routine clinical practice. METHODS: Participants in this observational study included 62 treatment-naïve patients with CRVO who received intravitreal injections of either ranibizumab or aflibercept. The demographic data, best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT) characteristics were evaluated at baseline and at months 1, 2, 3, 6, 12 and 18 post-treatment...

Purpose: To quantify changes in visual function parameters and in the retinal nerve fiber layer and macular thickness over a 5-year period in patients with Parkinson's disease (PD). Methods: Thirty patients with PD and 30 healthy subjects underwent a complete ophthalmic evaluation, including assessment of visual acuity, contrast sensitivity vision, color vision, and retinal evaluation with spectral-domain optical coherence tomography (SD-OCT). All subjects were reevaluated after 5 years to quantify changes in visual function parameters, the retinal nerve fiber layer, and macular thickness...

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 report unusual presentation of type 1A idiopathic macular telangiectasia (IMT). Methods. Two middle-aged women with bilateral IMT were examined. Results. Both patients presented with a gradual vision loss in both eyes. Fundus examination was unremarkable in one case and showed small macular telangiectasia in both eyes in the other case. Fluorescein angiography (FA) revealed early bilateral macular punctuated hyperfluorescence corresponding to the dilated capillaries in both cases. FA and fundus examination confirmed also the absence of vascular abnormalities in the middle or anterior fundus periphery in one case...

PURPOSE: To study the suitability of injectable microspheres based on poly(ester amide) (PEA) or poly lactic-co-glycolic acid (PLGA) as potential vehicles for intravitreal drug delivery in rat eyes. Dexamethasone-loaded PEA microspheres (PEA + DEX) were also evaluated. METHODS: Forty male Sprague Dawley rats were divided into four groups that received different intravitreally injected microspheres: PEA group (n = 12); PLGA group (n = 12); PEA + DEX group (n = 8); and control group (no injection, n = 8)...

A 2-month-old male infant with bilateral familial retinoblastoma was treated with intravenous chemotherapy and focal adjuvant therapy. At 5 months of follow-up, fundus examination and ultrasonography disclosed no recurrence; however, hand-held spectral-domain optical coherence tomography (SD-OCT) demonstrated subclinical recurrence within a previous regression scar. Subsequent treatment led to flat scar. Hand-held SD-OCT can be a useful tool for detection of subclinical recurrent retinoblastoma. [J Pediatr Ophthalmol Strabismus...

PURPOSE: To evaluate the reproducibility of intraretinal hard exudate (HE) quantification from spectral domain optical coherence tomography (SD-OCT) images of eyes with diabetic retinopathy (DR). METHODS: Cases with diabetic macular edema were enrolled. The area of HE obtained by B-scan segmentation was compared with the area obtained by en face segmentation. RESULTS: The mean ± SD for the HE area was 1.78 ± 1.37 mm with B-scan segmentation and 0...

PURPOSE: To quantify retinal capillary density and determine its correlation with visual acuity in patients with birdshot chorioretinopathy (BCR). METHODS: Patients with BCR and age-matched controls were imaged using a commercially available spectral domain optical coherence tomography angiography system (RTVue- XR Avanti; Optovue, Inc). We used the integrated software of the optical coherence tomography angiography device to analyze the foveal avascular zone area and the capillary density in the full retina as well as in the superficial capillary plexus and deep capillary plexus...
