Terson syndrome

Q: What is Terson syndrome? 

Answer: Terson syndrome is the presence of intraocular hemorrhages in association with hypertension. If this occurs in Sub-Arachnoid Hemorrhage (SAH), it implies poor prognosis and potentially high mortality. These patients usually lies at the higher grade on Hunt and Hess scale. This is due to abrupt increase in intracranial pressure (ICP). 

Clinicians should look it differently from relatively more benign retinal hemorrhages present in SAH. Although it is mostly pre-retinal but it can be sub-retinal, retinal, sub-hyaloidal, or intra-vitreal.
