Retinitis pigmentosa sine pigmenti. Debut with macular oedema.
METHODS
A 25-year-old woman, with metamorphopsia in her left eye of one year onset. The examination revealed a bilateral cystoid macular oedema (CME) and vascular attenuation. We describe the diagnostic tests, as well as differential diagnosis and treatment response with carbonic anhydrase inhibitors.


CONCLUSIONS
The retinitis pigmentosa sine pigment is a subtype of atypical retinitis pigmentosa characterised by the absence of pigment deposits. The night blindness is milder, and perimetric and electroretinographic impairment is lower. CME is an important cause of central vision loss, and responds to anhydrase carbonic inhibitors.
