The patient is 61 years of age, with complaint of decreased night vision for the past 10 years. He relates constriction diffusely of his visual field, although the visual fields were said to be normal in 1972. The patient is on no medication, with no significant past history. He is a retired newspaper reporter.
Ocular examination on April 19, 1982: Visual acuity, right eye 20/30; left eye, 20/30-2. Manifest refraction: OD +1.00 sphere; OS 0.75 sphere.
Fundus examination revealed numerous (almost confluent) nummular areas peripherally of depigmented or atrophic pigment epithelium with pigmented bridges between the nummular (circular) areas, completely encircling the posterior equator from the level of the posterior arcades out to the equator. In the macular region there are some crystalline-appearing deposits present.
Electrophysiological testing at that time revealed the visual fields as attached (Goldmann fields). Static perimetry performed in the right eye (attached) shows a reduction of temporal sensitivitiy, most marked in the red cone response. ERG responses are present, but of minimal amplitude (a- and b-wave) for both light adapted and dark adapted values. There is a marked delay in implicit times in the light adapted response. EOG is markedly subnormal, with light/dark ratio 1.07 OD and 1.14 OS.
