case_images: (a,c,d) Brain CT scan showing subarachnoid hemorrhage (SAH) due to middle cerebral artery (MCA) aneurysm rupture. (b) Note that basal cysterns are almost blood-free and SAH is highly localized in right hemisphere while Terson syndrome is in the left eye.

case_images: Considering morphological ratios and the size of a neck <3 mm, aneurysmal sac was angiographically embolized through three Guglielmini coils (Target 360  model) [Figure 2].
case_images: (a) Right eye: Retrohyaloid hemorrhage covering part of the macula and mild papilledema (optic disk swelling). The patient complained of decreased vision. (b) Left eye: Retrohyaloid hemorrhage covering the fovea and vitreous hemorrhage. The patient complained of blurred and decreased vision.

case_images: Tropicamide 1% was instilled, and through binocular indirect ophthalmoscopy, subhyaloid hemorrhage was detected in both the eyes in the macular region (bigger in the right eye than the left one) and vitreous hemorrhage in the left eye [Figure 3].
