Sectorial pigmentary retinopathy associated with head trauma.

Retinal lesions resembling retinitis pigmentosa were observed in a 39-year-old white male patient with a history of head trauma, reduced night vision, and periodic perception of light flashes. Perimetric testing revealed contracted superior-temporal fields. The results of numerous other tests of visual function, however, failed to support the tentative funduscopic diagnosis of sector retinitis pigmentosa.
