Abstract:
An analysis of four patients with congenital stationary night blindness showed that all had essentially normal fundi. We studied electro physiologic examinations including electroretinogram(ERG), electrooculogram(EOG) and pattern visual evoked potential(VEP). We classified these patients into two groups, one case as Schubert-Bornschein type and three cases as Riggs type based on the evaluation of scotopic and single bright flash ERG. The oscillatory potentials were absent in one case of Schubert-Bornschein type and reduced in two cases of Riggs type. The hereditary mode of three patients in one family was autosomal dominant.
