OBJECTIVE To characterize foveal atrophy in a heterogeneous group of patients with uveitis using clinical findings and high-definition (HD) optical coherence tomography (OCT). DESIGN Cross-sectional, retrospective case series. RESULTS The HD-OCT scans of 140 patients seen in a tertiary referral center were reviewed and 23 patients (33 eyes) with foveal atrophy were identified. All of the pa...

BACKGROUND Foveal detachment associated with foveoschisis usually takes a progressive course, and is associated with a poor visual outcome. The purpose of this study was to report the spontaneous resolution of foveal detachment in patients with myopic traction maculopathy without posterior vitreous detachment. METHODS A retrospective study involving eight cases of high myopia with foveoschisi...

OBJECTIVE To determine the relationship between foveal (retinal) thickness and visual acuity in diabetic macular edema through optical coherence tomography (OCT) mapping software. STUDY DESIGN Cross-sectional descriptive study. PLACE AND DURATION OF STUDY The Retina Clinic of Al-Shifa Trust Eye Hospital, Rawalpindi, from August 2011 to August 2012. METHODOLOGY Eighty eyes of 68 patients w...

This study investigates the effect of foveal load (i.e., processing difficulty of currently fixated words) on parafoveal information processing. Contrary to the commonly accepted view that high foveal load leads to reduced parafoveal processing efficiency, results of the present study showed that increasing foveal visual (but not linguistic) processing load actually increased the amount of para...

PURPOSE Macular pigment (MP) is composed of two dietary carotenoids, lutein and zeaxanthin, and a carotenoid generated by the retina, meso-zeaxanthin. There is large intersubject variability in peak optical density, spatial profile, and lateral extent of macular pigment, and it has been suggested that foveal architecture may play a role in this variability. This study is an initial investigatio...

PURPOSE To investigate the controversial origin of the foveal granular pattern at the center of the entoptic Purkinje vessel shadows. Both phenomena may be vividly elicited by oscillating a focused spot of light across the scleral surface of the eye in a circumferential direction. METHODS The site and pattern of oscillation of the light spot were varied and were correlated with the appearance...

purpose: to evaluate the influence of different confounding factors on the effect of intravitreal triamcinolone acetonide injection for refractory diabetic macular edema. methods: in a prospective placebo-controlled randomized clinical trial, 88 eyes with refractory diabetic macular edema were randomly assigned into two groups including 45 in the treatment group (4 mg intravitreal triamcinolone...

purpose: to evaluate the agreement between a new method for quantitative analysis of fundus or angiographic images using photoshop software and clinical judgment. methods: four hundred eighteen fundus and angiographic images of diabetic patients were evaluated by three retina specialists and then by computer using photoshop 7.0 software. four variables were selected for comparison: amount of ha...

three cases who underwent surgery in different areas of the craniofacial region were reported with bradycardia developing intraoperatively during flap traction. many cases of the oculocardiac reflex during treatment of the orbital region have been reported in the literature. this manuscript recorded that reflex bradycardia can occur during traction or stretching of any structure innervated by t...
