No pigment deposition in a patient with advanced retinitis punctata albescens

A 51-year-old woman had had night blindness since childhood and a progressive visual field defect. She was the product of a consanguineous marriage. The patient also exhibited numerous whitish-yellow punctate spots with no pigment deposition in her fundi, nonrecordable electroretinographic responses after 30 min of dark adaptation, and constricted visual fields bilaterally. We believe that our patient may be a case of retinitis punctata albescens without pigment.
