Corneal ulcer, also called keratitis, is an inflammatory or, more seriously, infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma. [ 1 ] [ 2 ] [ 3 ] It is a common condition in humans particularly in the tropics and in farming. [ 4 ]
Microbial keratitis (due to bacterial, fungal, or parasitic pathogens), as opposed to viral keratitis, is more commonly associated with the formation of corneal ulcers. Other risk factors for corneal ulcer formation include contact lens use, keratitis in the setting of eye trauma, underlying corneal disease or ocular surface diseases (such as ...
Peripheral Ulcerative Keratitis (PUK) is a group of destructive inflammatory diseases involving the peripheral cornea in human eyes. [1] The symptoms of PUK include pain , redness of the eyeball, photophobia , and decreased vision accompanied by distinctive signs of crescent-shaped damage of the cornea.
Exposure keratopathy (also known as exposure keratitis) is medical condition affecting the cornea of eyes. It can lead to corneal ulceration and permanent loss of vision due to corneal opacity. Normally, corneal surface is kept moist by blinking. During sleep, it is covered by lids. Increased corneal exposure to the air due to incomplete or ...
This classic herpetic lesion consists of a linear branching corneal ulcer (dendritic ulcer). During eye exam the defect is examined after staining with fluorescein dye. The underlying cornea has minimal inflammation. Patients with epithelial keratitis complain of foreign-body sensation, light sensitivity, redness and blurred vision.
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]
Mooren's ulcer is a rare idiopathic ocular disorder that may lead to blindness due to progressive destruction of the peripheral cornea.Although the etiology of Mooren's ulcer is poorly understood, recent evidence suggests that the pathogenesis of this disease appears to be the result of an autoimmune process directed against molecules expressed in the corneal stroma.
Hypopyon can be present in a corneal ulcer. It can occur as a result of Behçet's disease, endophthalmitis, panuveitis/panophthalmitis, or adverse reactions to some drugs (such as rifabutin). [1] Hypopyon is also known as sterile pus because it occurs due to the release of toxins and not by the actual invasion of pathogens. The toxins secreted ...
