Hyphema is the medical condition of bleeding in the anterior chamber of the eye between the iris and the cornea. [1] People usually first notice a loss or decrease in vision. [1] The eye may also appear to have a reddish tinge, or it may appear as a small pool of blood at the bottom of the iris in the cornea.
The anterior chamber is the aqueous humor-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium. [1] Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. In hyphema, blood fills the anterior chamber as a result of a hemorrhage, most commonly after a blunt eye injury.
A subconjunctival hemorrhage appears as a bright red patch on the white of the eye and is commonly referred to as a burst blood vessel. In hyphema, blood pools in the anterior chamber, where the iris (the colored part of the eye) and the pupil are located. Hyphemas are graded based on the amount of blood covering the cornea.
Uveitis–glaucoma–hyphaema (UGH) syndrome, also known as Ellingson syndrome, is a complication of cataract surgery, caused by intraocular lens subluxation or dislocation. The chafing of mispositioned intraocular lens over iris , ciliary body or iridocorneal angle cause elevated intraocular pressure (IOP) anterior uveitis and hyphema .
This is caused due to iris atrophy usually seen in FHI and exposure of the fragile iris vasculature to the vitreous fluid. The sudden change of pressure in the anterior chamber upon suction induced by the paracentesis, or during cataract surgery, causes bursting of the fragile superficial iris capillaries resulting in micro-bleeding.
Amsler sign also known as Amsler–Verrey sign is the name of the diagnostic finding seen in people with Fuchs heterochromic iridocyclitis (FHI). It is described as presence of blood in the aspirated aqueous fluid, in paracentesis of the anterior chamber, and is caused due to iris atrophy usually seen in FHI and exposure of the fragile iris vasculature to the aqueous fluid.
MVD, which is frequently fatal and is related to the much better-known Ebola virus, is sometimes known as "bleeding eye disease" because it damages people's blood vessels, causing them to bleed ...
Absolute glaucoma (H44.5) is the end stage of all types of glaucoma. The eye has no vision, absence of pupillary light reflex and pupillary response, and has a stony appearance. Severe pain is present in the eye. The treatment of absolute glaucoma is a destructive procedure like cyclocryoapplication, cyclophotocoagulation, or injection of 99% ...
