The American Academy of Ophthalmology practice guidelines recommend laser coagulation for people who have both mild to moderate nonproliferative diabetic retinopathy (NPDR) and clinically significant macular edema outside the fovea; treatment with anti-VEGF drugs is better than laser coagulation for clinically significant macular edema in the fovea.

Intraocular hemorrhage is classified based on the location of the bleeding: Hyphema (in the anterior chamber); Suprachoroidal hemorrhage (SCH) is a rare complication of intraocular surgery in which blood from the ciliary arteries enters the space between the choroid and the sclera.

On ultrasound, Coats' disease appears as a hyperechoic mass in the posterior vitreous without posterior acoustic shadowing; vitreous and subretinal hemorrhage may often be observed. [7] [8] On CT, the globe appears hyperdense compared to normal vitreous due to the proteinaceous exudate, which may obliterate the vitreous space in advanced disease.
Eye injury by impact of small plastic body. Based on the injury to the eyewall (outer fibrous coat of the eye consisting of cornea and sclera) Closed globe injury: the eye globe is intact, but the seven rings of the eye have been classically described as affected by blunt trauma.
