INTRODUCTION: Ocular disorders are useful in the characterisation of the different types of spinocerebellar ataxias (SCA); pigmentary retinitis is an alteration that is specifically associated to SCA type 7 and is characterised by night blindness, sensitivity to glare and progressive narrowing of the visual field.
CASE REPORT: A 34-year-old woman with clinical symptoms of progressive ataxia and visual impairment secondary to pigmentary retinitis. The patient had a personal history with an autosomal dominant pattern of a similar disorder in her father and paternal grandmother. In the genetic study she presented a triplet expansion in the SCA type 2 gene. CONCLUSIONS; Although pigmentary retinitis belongs to the SCA type 7 phenotype, our patient presented this retinal disorder, as in other cases of SCA type 2. A genetic study for SCA type 2 must therefore be conducted in patients with a degenerative ataxic clinical picture and who present evidence of pigmentary retinitis.
