Intraocular hemorrhage (sometimes called hemophthalmos or hemophthalmia) is bleeding inside the eye (oculus in Latin). Bleeding can occur from any structure of the eye where there is vasculature or blood flow, including the anterior chamber , vitreous cavity, retina , choroid , suprachoroidal space, or optic disc .
Intraocular hemorrhage can also result from elevated intracranial pressure caused by tumors or brain swelling, but this may go unnoticed if Terson's disease is not diagnosed. In order to treat the neurological and ocular components of the illness and avoid long-term visual impairment, early detection and timely intervention are essential.
Intravitreal injection was first mentioned in a study in 1911, in which the injection of air was used to repair a detached retina. [6] [7] [8] There were also investigations evaluating intravitreal antibiotics injection using sulfanilamide and penicillin to treat endophthalmitis in the 1940s, yet due to the inconsistency of results and safety concerns, this form of drug delivery was only for ...
Secondary hemorrhage, or rebleeding of the hyphema, is thought to worsen outcomes in terms of visual function and lead to complications such as glaucoma, corneal staining, optic atrophy, or vision loss. [1] Rebleeding occurs in 4–35% of hyphema cases and is a risk factor for glaucoma. [4]
Intraocular pressure should be measured as part of a routine eye examination. It is usually only elevated by iridocyclitis or acute-closure glaucoma, but not by relatively benign conditions. In iritis and traumatic perforating ocular injuries, the intraocular pressure is usually low.
The procedure is typically done in emergency situations when the intraocular pressure becomes too high, which can damage the optic nerve and lead to blindness if left untreated. [ 2 ] The most common cause of elevated intraocular pressure is orbital compartment syndrome (OCS) caused by trauma, retrobulbar hemorrhage , infections, tumors, or ...
Findings include delayed venous filling, hypofluorescence caused by hemorrhage and capillary nonperfusion, dilation and tortuosity of veins, leakage due to neovascularization and macular edema. Optical coherence tomography is an adjunctive test in branch retinal vein occlusion. Macular edema is commonly seen on optical coherence tomography exams.
