Ophthalmoscopic Appearances of Peripheral Pigmentary Tapeto‐retinal Dystrophy

The early ophthalmoscopic signs of typical retinitis pigmentosa are described, with the support of plain photographs of the fundus oculi. Ten cases, aged between 7 and 14 years, are reported, with others, showing early diagnostic ophthalmoscopic signs. Emphasis is placed on three early signs: retinal vessel narrowing, increased visibility of the choroid and the appearance of white material in the fundus. The association of this white material with pigment clumping is especially pointed out, with the suggestion that it is a secretory product of the pigment epithelium and is situated in or adjacent to the pigment epithelium. Critical ophthalmoscopy, plain fundal photography and leisured study of photographs comparing a suspected case with a normal relative can lead to early diagnosis in many patients in the first two decades of life before “bone-corpuscle” pigment deposits occur.
