[Intravitreal tissue plasminogen activator for treatment of central retinal vein occlusion associated with diabetic retinopathy].
OBJECTIVE
To evaluate the effects of intravitreal injection of tissue plasminogen activator (tPA) on central retinal vein occlusion(CRVO) associated with diabetic retinopathy (DR).


METHODS
A retrospective study of 42 eyes of 42 patients(mean age: 68 years, female/male = 20/22, 5 eyes associated with DR) with macular edema caused by CRVO treated with tPA. Best corrected visual acuity (BVCA or logarithm of the minimal angle of resolution: logMAR), macular thickness was mea sured by optical coherence tomography (OCT), and several variables were evaluated.


RESULTS
The mean logMAR and macular thickness improved significantly in the DR (-) group, but, no significant changes were observed in the DR (+) group. Post-operative posterior vitreous detachment (PVD) developed in 62% of the DR (-) group and none of the DR (+) group.


CONCLUSIONS
There may be no beneficial effects of intravitreal tPA on CRVO associated with diabetic retinopathy.
