Case report: Our purpose is to describe a case of an acute optic neuropathy with apical muscle thickening in a patient already diagnosed with giant cell arteritis. Loss of visual acuity and perimetric concentric constriction responded rapidly to intravenous glucocorticoid therapy. There has been no relapse during continued long-term therapy with cyclophosphamide. Discussion: Giant cell arteriti...

OBJECTIVES To evaluate the long-term natural history and effects of laser photocoagulation treatment in patients with diabetic retinopathy. DESIGN Follow-up study of the 214 surviving patients enrolled originally at the Johns Hopkins Clinical Center for the Early Treatment Diabetic Retinopathy Study (ETDRS), which was a clinical trial designed to evaluate the role of laser photocoagulation an...

Idiopathic central serous chorioretinopathy (ICSC) is an uncommon disease with the potential to cause loss of visual acuity, decreased color vision, and decreased depth perception. These visual changes may become permanent and require removal of aviators from flight status. This study reviews 55 eyes of 47 USAF aviators with ICSC examined at the United States Air Force School of Aerospace Medic...

PURPOSE To determine the role of vision and visual attention factors in automobile crash involvement. METHODS Drivers aged 65 to 84 years were identified during the baseline interview (1993-1995) of the Salisbury Eye Evaluation (SEE) Study. Crash involvement through December 1997 was determined from Maryland State motor vehicle records. Vision tests at baseline included distance acuity at nor...

PURPOSE To evaluate the visual outcome of patients with subfoveal choroidal neovascularization due to age-related macular degeneration, who received photodynamic therapy (PTD) in a clinical setting and to identify potential predictive visual and angiographic factors. DESIGN Interventional case series. METHODS The study included 74 patients with subfoveal choroidal neovascularization who und...

OBJECTIVE To describe the progression of geographic atrophy (GA) from age-related macular degeneration (AMD) with respect to visual acuity (VA) loss and enlargement of atrophy. DESIGN A prospectively observed case series. SETTING Tertiary retinal referral center. PARTICIPANTS One hundred twenty-three patients with GA due to AMD who completed at least 1 year of follow-up (median follow-up,...

seen on color photography (Figure 2). Her visual acuity loss and fundus findings were attributed to choroidal infarction that occurred immediately postoperatively. A cerebral internal carotid artery angiogram performed 4 days postoperatively, once her proptosis resolved, revealed a surgical clip at the expected location and no evidence of a clip or obstruction at the level of the ophthalmic art...

Purpose Vernier and grating acuity can be measured with swept-parameter visual evoked potentials (sVEP). However, whether sVEP Vernier and grating acuities are comparable in predicting letter acuity has not been systematically evaluated. This study evaluated the validity and reliability of sVEP Vernier and grating acuity for the detection of amblyopia in adults. Methods Three types of acuity ...
