In the literature, Terson's syndrome most commonly co-occurs with subarachnoid hemorrhage(SAH) secondary to rupture of an A-com or ICA aneurysm. It is usually observed bilaterally and the prognosis is poor. The authors report two rare cases of unilateral Terson's syndrome after rupture of MCA bifurcation aneurysm rupture. In both cases, retinal hemorrhage was noticed after early aneurysmal clipping ; after these were conservatively treated, the visual acuity of one patient improved slightly and that of the other showed no change. For early detection and proper management of retinal hemorrhage after subarachnoid hemorrhage, early and periodic fundoscopic examination appears to be important.
