OBJECTIVE To describe the incidence and outcomes of endophthalmitis after intravitreal injections of anti-vascular endothelial growth factor agents in the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT) and to assess the effect of prophylactic topical antimicrobials on incidence. DESIGN Cohort study within a randomized clinical(More)
A mechanics based mathematical model for the behavior of an eye encircled by a scleral buckle, a procedure used by surgeons to correct retinal detachment, is developed. Closed form analytical solutions are obtained, and results of numerical simulations based on those solutions are presented. The effects of material and geometric parameters of the scleral(More)
A mechanics-based mathematical model of an eye possessing a posterior retinal detachment is presented for the case where an encircling scleral buckle (a cerclage) is sutured around the equator of the eye. The mechanical behaviour of the retina and the globe, both before and after applying the cerclage, is studied. An energy formulation yields the(More)
AIMS To evaluate the presence of cognitive bias among retinal specialists when recommending treatment options for cystoid macular oedema (CMO) secondary to retinal vein occlusion (RVO). METHODS Two randomly chosen samples of retina specialists were surveyed regarding their treatment and dosing regimen choices among three antivascular endothelial growth(More)
An improved solution to the mechanics-based mathematical model for retinal detachment developed by Bottega et al. (2013, Math. Med. Biol., 30, 287-310) is found by removing the simplifying assumption of negligible meridian displacement employed in that study. The model considers retinas with and without central tears and takes contraction of the vitreous(More)
A patient displayed a pink mass on the right optic disc and normal visual function that was diagnosed as a capillary hemangioma. Seven months later, he developed typical features of nonarteritic anterior ischemic optic neuropathy (NAION) in that eye. Such a long latency between "preeruptive" and "eruptive" disc edema has not been well documented in NAION.
