Maculopathy is characterized by a progressive loss of central vision, usually bilateral, that greatly impairs vision functions. In any case, degenerative maculopathy never leads to complete blindness since lateral [ Results. The mean metamorphopsia score was 0.30 ± 0.46, and 50 of 129 patients (39%) had metamorphopsia. Metamorphopsia was more severe in eyes with macula-off rhegmatogenous RD than those with macula-on (P < .001).Eighteen of 50 eyes with metamorphopsia exhibited abnormal structures in the macular region (epiretinal membrane, disruption of the photoreceptor inner and outer segment junction. 3.

(ERMs), also commonly known as cellophane maculopathy or macular puckers, are avascular (having few or no blood vessels), semitranslucent, fibrocellular membranes that form on the inner surface of the retina. They most commonly cause minimal symptoms and can be simply observed, but in some cases they can result in painless. Background: Although macular pucker removal in patients with metamorphopsia due to a macular pucker is a traditional elective vitreoretinal indication, we found that patients were not uniformly satisfied after surgery. We wished to study outcome in vision and metamorphopsia in patients undergoing macular pucker surgery, to assess changes between 1- and 5-year follow-up, as well as patient.
Photopsia and phosphenes. Phosphenes and photopsia are brief entoptic phenomena. Phosphenes can be induced by mechanical (eye rubbing, sneezing), electrical, and magnetic stimulation of the retina and visual cortex as well as by the spontaneous firing of retinal cells. Pressure phosphenes consist of seeing colors and lights with eye rubbing Diseases of the retina may lead to visual impairment, visual field loss, and more complex disorders such as metamorphopsia (distorted vision) and clouding. Ophthalmoscopy is the preferred diagnostic method for identifying retinal diseases, Definition: benign hyperplasia of the retinal pigment epithelium; Diagnostics:.
