RESUMO
A Síndrome de Urrets-Zavalia apresenta achados oculares bem descritos, porém sua fisiopatologia ainda é incerta. A isquemia iriana é o mecanismo proposto mais comum. Descrevemos dois casos submetidos à ceratoplastia lamelar profunda (CLP) realizadas pelo mesmo cirugião que desenvolveram a síndrome. No primeiro caso, a indicação cirúrgica foi para o tratamento de opacidade corneana e, no segundo, para o de ceratocone. No pós-operatório, ambos os pacientes evoluíram com pupila dilatada fixa que não regrediu totalmente apesar do tratamento administrado.
ABSTRACT
The Urrets-Zavalia Syndrome presents well described ocular findings, even though its physiopathology is still unsure. Iris ischemia is the most common proposing mechanism. We describe two cases that underwent deep lamellar keratoplasty (DLK) performed by the same surgeon and developed the syndrome. In the first case, the surgical indication was for corneal opacity treatment and, in the second case, for keratoconus treatment. During the post-operatory, both patients developed fixed dilated pupil, which didn't regress completely inspite of the onset treatment.
