[ 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.
Ophthalmology. Recurrent corneal erosion is a disorder of the eyes characterized by the failure of the cornea 's outermost layer of epithelial cells to attach to the underlying basement membrane ( Bowman's layer ). The condition is excruciatingly painful because the loss of these cells results in the exposure of sensitive corneal nerves.
Neurotrophic keratitis ( NK) is a degenerative disease of the cornea caused by damage of the trigeminal nerve, [ 1] which results in impairment of corneal sensitivity, spontaneous corneal epithelium breakdown, poor corneal healing and development of corneal ulceration, melting and perforation. [ 2] This is because, in addition to the primary ...
When eyes are untaped during general anaesthesia, the incidence of ocular injury has been reported to be as high as 44%. [ 1][ 2] If tape is used to hold the eyes closed, ocular injury occurs during 0.1-0.5% of general anaesthetics, and is usually corneal in nature. [ 3][ 4] Intraoperative eye injuries account for 2% of medico-legal claims ...

Acanthamoeba keratitis ( AK) is a rare disease in which amoebae of the genus Acanthamoeba invade the clear portion of the front ( cornea) of the eye. It affects roughly 100 people in the United States each year. [ 2] Acanthamoeba are protozoa found nearly ubiquitously in soil and water and can cause infections of the skin, eyes, and central ...
Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense direct or reflected sunlight) or artificial (e.g. the electric arc during welding) sources. Photokeratitis is akin to a sunburn of the cornea and conjunctiva.
Corneal perforation. Corneal perforation is an anomaly in the cornea resulting from damage to the corneal surface. A corneal perforation means that the cornea has been penetrated, thus leaving the cornea damaged. The cornea is a clear part of the eye which controls and focuses the entry of light into the eye. Damage to the cornea due to corneal ...
