We have used a color-matching technique to obtain estimates of the optical density of cone photopigments as a function of retinal illuminance in patients with insulin-dependent diabetes mellitus (IDDM). We found that the half-bleach illuminance of some patients is abnormally high. That is, it takes more light to bleach an equivalent amount of photopigment(More)
A new, clinically applicable test has been developed to measure the bleaching of the foveal cone photopigments. This noninvasive test is called steady-state color matching. Steady-state color matching is based on the dependence of a color match on the optical density of the cone photopigments. By measuring the color match as a function of retinal(More)
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 study was performed to determine how amphotericin B is distributed in the eye after direct intravitreal injection. Radiolabeled amphotericin B was administered by direct injection into the vitreous space of unmodified phakic control or vitrectomized aphakic eyes in the rabbit model. The eyes were removed at different post-injection times, frozen and(More)
It is widely held that ocular toxoplasmosis (1) involves inner retinal layers and (2) shows marked vitreous cellular reaction. This article reports on punctate outer retinal layer toxoplasmosis, a subset of ocular toxoplasmosis characterized by grey-white lesions of deep retina and retinal pigment epithelium, and associated with little or no overlying(More)
An electro-oculogram ratio of less than one was found to be caused by limited ocular excursions under photopic conditions in a patient with a rod-cone dystrophy. Because this inverse electro-oculogram ratio was not caused by a decrease in standing potential under photopic conditions, it should be considered an artefact.
