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 .
It appears as an aftereffect of an intracranial hemorrhage (such as traumatic brain injury or subarachnoid hemorrhage). Intraocular bleeding results from the condition's abrupt and severe rise in intracranial pressure, which is then conveyed to the eyes through the optic nerve sheath. Terson's syndrome's most frequent cause.
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 most common cause of elevated intraocular pressure is orbital compartment syndrome (OCS) caused by trauma, retrobulbar hemorrhage, infections, tumors, or prolonged hypoxemia. [3] Absolute contraindications to canthotomy include globe rupture. Complications include bleeding, infections, cosmetic deformities, and functional impairment of ...

Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
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]
Subgaleal hemorrhage, also known as subgaleal hematoma, is bleeding in the potential space between the skull periosteum and the scalp galea aponeurosis (dense fibrous tissue surrounding the skull). Symptoms
