Visual fields correlate better than visual acuity to severity of diabetic retinopathy

Visual fields in diabetic retinopathy.

A pupillometric correlate of scotopic visual acuity

While not easily fit into the classic descriptions of the pupillary light reflex, previous studies reported that changes in the spatial composition of the retinal image can evoke a pupillary response. The present study extends this observation by showing that the pupil constricts in response to scotopic as well as photopic spatial patterns. Moreover, the amplitude of the scotopic response decre...

Visual Psychophysics in Diabetic Retinopathy

INTRODUCTION Irreversible and severe visual loss may represent the end of long lasting diabetic retin-opathy. The progression of visual impairment and the quantification of final residual visual function are currently determined by means of diagnostic tests which rely on the physiological and mathematical principles of psychophysics. The best known among these tests is the quantification of vis...

Correlation between Visual Acuity and Optical Coherence Tomography-Measured Retinal Thickness in Diabetic Macular Edema

Background and Objective: Diabetic macular edema (DME) is one of the common complications of diabetes which significantly accounts for preventable visual impairment and blindness. Central macular thickness (CMT) is a feature found in DME patients. This study aims to determine the relationship between optical coherence tomography (OCT)-measured CMT and visual acuity (VA) in patients with DME bef...

Visual Prognosis of Proliferating Diabetic Retinopathy.

SINCE we are not yet able to prevent retinal changes in diabetic patients we must be content to accept, lessen, or slow the progress of these degenerative retinal vascular changes. The latest method of lessening them is the " Houssay phenomenon", which is said to have a favourable effect in diabetic retinopathy through destruction of the pituitary gland. The percentage of diabetic patients with...
