Road traffic accidents (RTAs) with head and facial trauma may also have an eye injury – these are usually severe in nature with multiple lacerations, shards of glasses embedded in tissues, orbital fractures, severe hematoma and penetrating open-globe injuries with prolapse of eye contents. Other causes of intraocular trauma may arise from ...
The prognosis for penetrating head injuries varies widely. [11] Penetrating facial trauma can pose a risk to the airway and breathing; airway obstruction can occur later due to swelling or bleeding. [12] Penetrating eye trauma can cause the globe of the eye to rupture or vitreous humor to leak from it, and presents a serious threat to eyesight ...
A penetrating globe injury with a retained foreign object, called an intraocular foreign body, has a different prognosis than a simple penetrating trauma. Therefore, intraocular foreign body injuries are considered a distinct type of ocular injury. [4] Open-globe injuries are also classified by the anatomic region or zone of injury: Zone 1 ...
Sympathetic ophthalmia (SO), also called spared eye injury, is a diffuse granulomatous inflammation of the uveal layer of both eyes following trauma to one eye. It can leave the affected person completely blind. Symptoms may develop from days to several years after a penetrating eye injury. It typically results from a delayed hypersensitivity ...
Corneal abrasion is a scratch to the surface of the cornea of the eye. [3] Symptoms include pain, redness, light sensitivity, and a feeling like a foreign body is in the eye. [1] Most people recover completely within three days. [1] Most cases are due to minor trauma to the eye such as that which can occur with contact lens use or from ...
A subconjunctival hemorrhage can often occur without any obvious cause or harm to the eye. A strong enough sneeze or cough can cause a blood vessel in the eye to burst. Hyphema is a result of blunt or penetrating trauma to the orbit that increases intraocular pressure, causing tears in the vessels of the ciliary body and iris.
Symptoms of endophthalmitis include severe eye pain, vision loss, and intense redness of the conjunctiva. [1] Bacterial endophthalmitis more commonly presents with severe and sudden symptoms whereas fungal causes have a more insidious onset and severity, with 80% of ocular candidiasis (both chorioretinitis and endophthalmitis) being asymptomatic. [3]
Causes can include coughing, vomiting, heavy lifting, straining during acute constipation or the act of "bearing down" during childbirth, as these activities can increase the blood pressure in the vascular systems supplying the conjunctiva. Other causes include blunt or penetrating trauma to the eye.
