purpose: to compare rose-k and conventional rgp contact lenses in terms of visual acuity, visual function and comfort in keratoconus patients. method: fifty-four patients with keratoconus were randomly fitted with rose-k and conventional rgp contact lens (wohlk contact lens), by one experienced ophthalmologist using a standard (three touch point) approach. general and demographic information, k...

We would like to thank Ian Murdoch and David Crabb for their important letter pointing out the tendency underestimate global burden of glaucoma when focusing solely on central vision loss. Glaucoma is leading cause irreversible loss globally, whose share overall blindness prevalence has been growing steadily as investments have begun pay off in fight against diseases such cataract trachoma.1Bur...

Objective: Remote Ischemic Preconditioning (RIPC) as the transient ischemia and reperfusion of the arm is a promising method for protecting different tissue from future ischemia. These effects might be mediated through vascular and endothelial growth factor (VEGF) pathway. We investigated the influence of RIPC on diabetic macular edema (DME) as a chronic ischemic condition in patients who were ...

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...
