We evaluated the fate of preretinal hemorrhage in diabetic retinopathy in regard to the final visual acuity. We reviewed a total of 106 eyes, 93 cases, with pre-retinal hemorrhage greater than 2 disc diameter (DD). The size and the location of hemorrhage were numeri-cally recorded and processed for each eye in the series. Massive preretinal hemorrhage was most frequently located in the posterior fundus area surrounded by the upper and the lower vascular arcades.

We arbitrarily classified 81 eyes, which were followed up for 6 months or more without resorting to vitreous surgery, into three groups according to the fate of preretinal hemorrhage. In the first group including 16 eyes (20%), the preretinal hemorrhage was absorbed leaving no fibrous proliferation. Mild preretinal prolif-eration resulted in the second group of 17 eyes (21%). Marked fibrous proliferation resulted in the third group of 48 eyes (59%). As a marked tendency, eyes with more advanced fibrous proliferation were associated with more massive preretinal hemorrhage. Traction-induced retinal detachment occurred only in eyes with consequent fibrous proliferation, in 12% in group II and in 69% in group III.

Our findings indicate that massive preretinal hemor-rhage is a major etiological factor for preretinal fibrous proliferation and traction-induced retinal detachment in diabetic retinopathy.
