Idiopathic central retinal vein occlusion in a thrombophilic patient with the heterozygous 20210 G/A prothrombin genotype.
OBJECTIVE
To report the occurrence of monolateral central retinal vein occlusion in a patient with heterozygous 20210 G/A prothrombin genotype, known to be associated with high thrombophilic risk.


METHODS
A monolateral central retinal vein occlusion was diagnosed in a 71-year-old woman, who had suffered from a deep vein thrombosis in her left leg at the age of 36 years. Mutations of the genes involved in the coagulation process were investigated by DNA polymerase chain reaction.


RESULTS
DNA analysis showed the patient to be heterozygous for the prothrombin 20210 G/A genetic variation.


CONCLUSIONS
The 20210 G/A prothrombin gene mutation may be associated with central retinal vein occlusion.
