Terson Syndrome Secondary to Subarachnoid Hemorrhage: A Case Report.

BACKGROUND

Terson syndrome is a serious complication of subarachnoid hemorrhage (SAH) that includes any intraocular hemorrhage and may result in blurred vision or even blindness. However, it is often overlooked clinically.

CASE DESCRIPTION: A 42-year-old man presented with coma due to rupture of a left posterior communicating artery aneurysm. A preoperative computed tomography scan demonstrated SAH and bilateral fundus hemorrhage. Visual evoked potential and B-scan ocular ultrasound revealed vitreous hemorrhages, features consistent with Terson syndrome. Pars plana vitrectomy was performed 2 weeks after SAH with a subsequent improvement of visual acuity.

CONCLUSIONS

Early identification is important for the recovery of the patient's nervous system and ophthalmology. Neurosurgeons should be aware of the pathology and pay attention to it to maximize patient's benefit.
