SUMMARY
We retrospectively evaluated the results of pars-plana vitrectomy performed in 14 eyes (nine patients) with vitreous hemorrhage due to Terson 's Syndrome. Cranial encephalic trauma and spontaneous rupture of intracranial aneurysm were the causes of the intracranial hemorrhage in 55,5 and 44,5% of the cases, respectively and the vitrectomy occurred, in average, 5 months after the vitreous hemorrhage. In four eyes it was observed during the surgery, partial posterior vitreous detachment in a dome shape in the macular area; and in three eyes it was observed the presence of macular epiretinal membrane. Posterior subcapsular cataract developed in 28% of the cases. One eye developed retinal detachment. There was visual acuity improvement in 92% of the cases and 64% of the eyes reached a final vision of 20/40 or better. In cases that early signs of vitreous hemorrhage resolution are not observed, vitrectomy can be considered an effective and safe procedure, with a ready visual rehabilitation in Terson 's Syndrome.
