ABSTRACT

ABSTRACT Alport Syndrome is a hereditary disease that is caused by a gene mutation and affects the production of collagen in basement membranes; this condition causes hemorrhagic nephritis associated with deafness and ocular changes. The X-linked form of this disease is the most common and mainly affects males. Typical ocular findings are dot-and-fleck retinopathy, anterior lenticonus, and posterior polymorphous corneal dystrophy. Some cases involving polymorphous corneal dystrophy and corneal ectasia have been previously described. Here we present a case report of a 33-year-old female with Alport syndrome, posterior polymorphous corneal dystrophy, and irregular astigmatism, whose visual acuity improved with a rigid gas permeable contact lens.


RESUMO A síndrome de Alport é descrita como uma doença hereditária que afeta um gene relacionado à produção de colágeno das membranas basais causando nefrite hemorrágica associada com surdez e alterações oculares. A forma ligada ao X é a mais comum e afeta principalmente homens. Os achados oculares típicos são retinopatia em ponto-mancha, lenticone anterior e distrofia polimorfa posterior. Alguns casos foram descritos de associação entre a distrofia polimorfa posterior e ectasia corneana. Nós apresentamos um caso de paciente do sexo feminino, 33 anos, diagnóstico de síndrome de Alport, distrofia polimorfa posterior e astigmatismo irregular, que apresenta melhora da acuidade visual após adaptação com lentes de contato rígidas gás permeáveis.
