a 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. slit lamp examination showed arborizing conjunctival vessels and dry eye. fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. an ascert...

introduction : laser therapy prevents complications of proliferative diabetic retinopathy (pdr), central retinal vein occlusion (crvo) and branch retinal vein occlusion (brvr), but its effect on visual acuity is controversial. this study evaluated the effect of laser on visual acuity in these patients. materials and methods: this interventional study conducted before–after treatment and evaluat...

OBJECTIVES To examine the association between visual and hearing impairment and motor vehicle collision (MVC) involvement in older drivers. DESIGN Retrospective cohort study. SETTING North central Alabama. PARTICIPANTS Population-based sample of 2,000 licensed-drivers aged 70 and older. MEASUREMENTS Visual acuity was measured using the Electronic Visual Acuity test. Contrast sensitivity...

OBJECTIVE To identify clinical predictive factors for visual outcome in a large series of patients who underwent plaque radiotherapy for uveal melanoma. DESIGN Clinical factors, including patient data, tumor features, and radiation variables, were analyzed for their impact on visual acuity using Cox proportional hazards regression models. PARTICIPANTS Patients with uveal melanoma and initia...

Abnormal visual experience during childhood often leads to amblyopia, with strong links to binocular dysfunction that can include poor acuity in both eyes, especially in central vision. In animal models of amblyopia, the non-deprived eye is often considered normal and what limits binocular acuity. This leaves open the question whether monocular deprivation (MD) induces binocular dysfunction sim...

Background: The natural history of ocular lesions in Behçet's disease is toward severe loss of vision/blindness in few years, whereas cytotoxic drugs have changed the outcome. Several open labeled cohort studies showed pulse cyclophosphamide (PCP) to be the best choice. Since one third of these patients are resistant to PCP it is important to know how much improvement one can expect from the r...

background: vision therapy/orthoptics(vt/o) is a package of treatments that enables patients to achieve the maximum level of visual performance.the aim was to determine the effect of three months vision therapy/orthoptics on best corrected visual acuity (bcva), fusion, stereopsis and ocular alignment in 3-7 year old children. materials and methods: in this randomized clinical trial study, 80 ch...

This study examined the quantitative relationship between foveal visual acuity and contrast sensitivity for large-letter optotypes in a group of patients with retinitis pigmentosa (RP), in order to assess more completely the extent of foveal vision loss in this group of hereditary retinal dystrophies. High-contrast visual acuity and large-letter contrast sensitivity were measured with a compute...

PURPOSE To evaluate the decibel loss on the Macular threshold protocol of the Humphrey visual field as a reliable functional outcome of the intravitreal bevacizumab treatment. METHODS Thirteen patients were evaluated at baseline and on the week 6 for best corrected visual acuity, optical coherence tomography central macular thickness and decibel loss on Macular threshold protocol of the Humph...
