Purpose. To determine factors associated with the presence of significant ocular injury in subjects with orbital fractures. Subjects. A consecutive prospective cohort of 161 patients presenting to a general tertiary referral hospital with orbital fractures and undergoing initial conservative treatment was identified. Subjects were assessed at time of injury for the need for emergency surgery, a...

Human vision is heterogeneous around the visual field. At a fixed eccentricity, performance better along horizontal than vertical meridian and lower upper meridian. These asymmetric patterns, termed fields, have been found in numerous tasks, including those mediated by contrast sensitivity spatial resolution. However, it unknown whether resolution asymmetries are confined to cardinal meridians ...

 Abstract Background: Transpupillary thermotherapy is a new treatment for subfoveal choroidal neovascularization which needs further evaluation. This study was aimed to evaluate the efficacy of transpupillary thermotherapy on regression of occult subfoveal choroidal neovascularization with or without pigment epithelial detachment in patients with age-related macular degeneration. Methods: In a ...

PURPOSE To characterize binocular visual acuity summation and inhibition in participants of a population-based ocular epidemiologic study. METHODS A complete ophthalmic examination of Latinos, aged 40 or more years, measured binocular and monocular distance visual acuities by a standard early-treatment diabetic retinopathy study (ETDRS) protocol. The proportions of participants who demonstrat...

background: photorefractive keratectomy is a popular mean to correct refractive errors of the eye and haze formation is one of the most important complications of the surgery. although standard dose of intraoperative mitomycin c has shown to be effective in reduction of this complication, potential side effects of mitomycin c promote us to show if the lower concentration of mitomycin c has t he...

purpose: to report treatment with intravitreal triamcinolone acetonide (ivta) in a patient with cystoid macular edema (cme) secondary to retinitis pigmentosa (rp). case report: a 22-year-old male patient with rp presented with progressive visual loss. visual acuity was 9/10 in the right eye and 10/10 in the left eye without refractive error. examination revealed cme in the right eye. after fail...

BACKGROUND The purpose of this study was to determine the predictive value of flash visual-evoked potentials (VEP), relative afferent pupillary defect, and presence of orbital fractures in patients with traumatic optic neuropathy. METHODS A prospective study was conducted in 15 patients with indirect traumatic optic neuropathy. All patients underwent a thorough ophthalmic examination. Initial...
