THE CLINICAL FEATURE OF SUBRETINAL AND VITREOUS HEMORRHAGE ASSOCIATED WITH SENILE MACULAR DEGENERATION / 解放军医学杂志

ABSTRACT

To study the clinical feature and surgical outcome of subretina and vitreous hemorrhage associated with senile macular degeneration (SMD). Vitrectomy was performed in 29 eyes of 29 patients with subretina and vitreous hemorrhage associated with SMD. Changes in the retina were observed, and the results of surgery were analyzed. The results showed that there was submacular hemorrhage in 16 patients, in whom 4 showed periomacular subretinal hematoma. There was peri macular subretinal hematoma only in 13 cases. The pathological changes in the macular region included discoid degeneration, submacular neovascularization, fixed foldings, exudation, scar and atrophic discoid cicatrization. All patients got visual acuity improvement after surgery. However those patients who had subretinal hemorrhage got less improvement of visual acuity than the others. It suggested that the SMD patients who was complicated by subretinal hemorrhage had a severer macular lesion. Pars plana vitrectomy could restore central vision of patients who suffered from subretinal and vitreous hemorrhage. But the outcome was related with the position of subretinal hemorrhage.
