Coats' disease and bilateral cataract in a child with Turner syndrome: a case report

To report the first case in which Coats' disease was observed with infantile cataract in a girl with Turner syndrome (TS).

We examined a 4-year-old female infant with TS who was referred with a diagnosis of leukocoria in the left eye.

Examination under anaesthesia revealed a bilateral punctate cataract and left eye fundus showed vascular retinal abnormalities typical of Coats' disease. Cryotherapy was performed on the telangiectatic vessels and the child was followed up for a period of 12 months. Despite cryotherapy resulting in regression of the peripheral exudates, an exudative maculopathy persisted with poor visual outcome. We suggest that Coats' disease should be considered as a rare ocular manifestation in TS.
