Vision threshold profiles in sector retinitis pigmentosa
R. W. Massof and D. Finkelstein
Absolute vision thresholds were measured along the horizontal and vertical
meridians in four patients from one pedigree and one patient from a second
pedigree with dominantly inherited sector retinitis pigmentosa. From these
studies we find that (1) visual function is decreased for all parts of the
retina, including the fovea, (2) rod and cone systems are affected to the
same degree, and (3) the disease progression is confined to the inferior
portion of the retina.
