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.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
