[Atypical tapetoretinal degeneration simulating a neurologic syndrome].

We report the case of a 57-year-old woman with progressive bilateral visual acuity loss, presumed during ten years to be secondary to a neurological disease. Ophthalmological examination showed for both eyes pallor of the optic discs and arteriolar narrowing. Periphery was normal, without pigment clumping. Fluorescein angiography showed a widespread irregular hypopigmentation and discovered a bilateral macular edema. Abnormal rod function was confirmed by electroretinography. A review of the literature data shows the variety of clinical symptoms in patients with retinitis pigmentosa and the frequency of atypical non-pigmented forms. Those forms are usually considered as early stages of the disease. Besides, macular lesions, and macular edema in particular, are frequently reported.
