Ondokuz Mayıs Üniversitesi, Tıp Fakültesi, Göz Hastalıkları AD., Samsun Purpose: To evaluate the results of pars plana vitrectomy (PPV) for intravitreal hemorrhage as a late complication of branch retinal vein occlusion (BRVO).
Material and Methods: The records of 33 patients (33 eyes; 18 female, 15 male) who underwent PPV for intravitreal hemorrhage secondary to BRVO from August 1997 to January 2003 were retrospectively evaluated. Indications of PPV were non-clearing vitreous hemorrhage at least 3 months follow-up or retinal detachment findings associated with it. The cases of BRVO secondary to uveitis weren't included in this study.
Results: The mean age of the patients was 66 (38-85 years) years. The mean postoperative follow-up was 9 (2-24 months) months. BRVO was superotemporal vein in 20 cases (60%), inferotemporal vein in 6 cases (18%) and other veins in 7 cases (22%). Four patients have preoperative tractional retinal detachment. Preoperative visual acuities in all cases were between perception/projection to finger count. The visual acuities were 0.1 or more in 24 (72%) cases in last postoperative controls. The postoperative complications were cataract in 6 cases, retinal detachment in 3 and rehemorrhage in 3.
Conclusion: Anatomic and visual prognosis in retinal branch vein occlusion are favorable after pars plana vitrectomy. Epiretinal membrane and retinal detachment are frequently associated complications with vitreous hemorrhage secondary to BRVO.
