Central retinal vein thrombosis as an initial manifestation of heterozygous protein C deficiency: case report

RESUMO

The purpose of this paper is to report a case of central retinal vein thrombosis associated with isolated heterozygous protein C deficiency. Acute oclusion of the central retinal vein presents as one of the most dramatic pictures in ophthalmology. It is often a result of both local and systemic causes. A rare systemic cause is heterozygous protein C deficiency, and it usually occurs in combination with other thrombophilic conditions. This case highlights that isolated heterozygous protein Cdeficiency may be the cause of central retinal vein thrombosis and underscores the importance of its screening in yong patients with this ophthalmologic disease.
