Optic Disc Pit with Sectorial Retinitis Pigmentosa
Sectorial retinitis pigmentosa (RP) and optic disc pit (ODP) are rare clinical conditions. We present a 40-year-old woman with a history of mild night blindness and decreased vision in the right eye for about 5 years. Fundus examination revealed retinal pigmentary changes in the superior and inferotemporal sectors covering the macula and reduced arterial calibre and ODP at the temporal edge of ...
متن کاملRetinitis pigmentosa: visual function and multidisciplinary management.
Retinitis pigmentosa (RP) is a leading cause of blindness and visual disability in younger people. Optometrists have a major role in detecting RP and in reducing the visual disability associated with RP. This review summarises the literature relating to visual function in people with RP, with particular attention given to night-blindness, visual acuity decrease and visual field contraction. The...
متن کاملRod phototransduction in retinitis pigmentosa. Distinguishing alternative mechanisms of degeneration.
PURPOSE To test alternative hypotheses concerning the mechanisms of rod degeneration in retinitis pigmentosa (RP). METHODS Full-field rod electroretinograms and rod visual fields were measured for 15 patients with RP and a normal control group. The rod a-wave was fitted with a computational model based on known transduction biochemistry. The values of td (the initial delay), S (a sensitivity ...
متن کاملVisual training and emotional state of people with retinitis pigmentosa.
The purpose of the study was to improve the visual functioning of people with restriction in contrast sensitivity (CS), such as retinitis pigmentosa (RP), by means of a visual training program. Twenty-six volunteers with RP participated, distributed in two groups: 15 who made up the experimental group (who received the training program) and 11 who participated as a control group (without traini...
متن کاملNext-generation genetic testing for retinitis pigmentosa
Molecular diagnostics for patients with retinitis pigmentosa (RP) has been hampered by extreme genetic and clinical heterogeneity, with 52 causative genes known to date. Here, we developed a comprehensive next-generation sequencing (NGS) approach for the clinical molecular diagnostics of RP. All known inherited retinal disease genes (n = 111) were captured and simultaneously analyzed using NGS ...
