Abstract

Branch retinal vein occlusion is a disease of relatively good prognosis concerning visual acuity. We have studied 33 patients with temporal branch retinal vein occlusion who have not been treated to investigate the cause of branch retinal vein occlusion and poor visual outcome. The possible causes were as follow; Hypertension was found in 25 patients, hyperlipidemia in two, adiposity in one, Diabetes Mellitus in one and unknown causes in 4 patients. Among those twenty five patients who have hypertension, 6 of them showed eleveted systolic blood pressure, while diastolic blood pressure remains normal, suggesting that high systolic pressure might be a more significant factor than diastolic pressure. Poor visual outcome has been found in eight patients. Four as chronic macular edema. Two has preretinal membrane and remaining two has vitreous opacity and macular hole, respectively. In overall, better prognosis has been observed in inferotemporal branch retinal vein occlusion than insuperotemporal branch retinal vein occlusion. Also, patients who did not have macular hemorrhage had better visual outcome than those who had.
