Terson syndrome or Tersons syndrome is the occurrence of a vitreous hemorrhage of the human eye in association with subarachnoid hemorrhage. Vitreous hemorrhage of the eye can also occur in association with intracranial hemorrhage and elevated intracranial pressure (ICP). Intraocular hemorrhage can be a subretinal, retinal, preretinal, subhyaloidal, or intra-vitreal hemorrhage. Its likely cause is a rapid increase in ICP. The classic presentation is in the subhyaloidal space, which is beneath the posterior vitreous face and in front of the retina.In subarachnoid hemorrhage, 13% of patients have Tersons syndrome, which is associated with more severe SAH (higher Hunt-Hess score, a marker of severity), and risk of death is significantly increased.The first known report of the association was by the German ophthalmologist Moritz Litten in 1881. Still, French ophthalmologist Albert Tersons name is more commonly associated with the condition after a report by his hand from 1900. References

NICE classification
In colonoscopy, colorectal polyps can be classified by NICE (Narrow-band imaging International Colorectal Endoscopic):

Treatment
Polyps can be removed during a colonoscopy or sigmoidoscopy using a wire loop that cuts the stalk of the polyp and cauterises it to prevent bleeding. Many "defiant" polyps—large, flat, and otherwise laterally spreading adenomas—may be removed endoscopically by a technique called endoscopic mucosal resection (EMR), which involves injection of fluid underneath the lesion to lift it and thus facilitate endoscopic resection. Saline water may be used to generate lift, though some injectable solutions such as SIC 8000 may be more effective. Minimally invasive surgery is indicated for polyps that are too large or in unfavorable locations, such as the appendix, that cannot be removed endoscopically. These techniques may be employed as an alternative to the more invasive colectomy. Follow-up
By United States guidelines, the following follow-up is recommended:
