Keratitis is a condition in which the eye's cornea, the clear dome on the front surface of the eye, becomes inflamed. [1] The condition is often marked by moderate to intense pain and usually involves any of the following symptoms: pain, impaired eyesight, photophobia (light sensitivity), red eye and a 'gritty' sensation. [2]
Lagophthalmos, the inability to close the eyelids completely is the main cause of exposure keratopathy.Common cause of lagophthalmos is facial nerve (CN VII) palsy. Facial nerve function may affect in several conditions like cerebrovascular accident, head trauma, brain tumors, Bell's palsy etc. Physiological inability to close the eyelids during sleep (nocturnal lagophthalmos) may also cause ...
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 ]
Thygeson's superficial punctate keratopathy (TSPK) is a disease of the eyes.The causes of TSPK are not currently known, but details of the disease were first published in the Journal of the American Medical Association in 1950 by American ophthalmologist Phillips Thygeson (1903–2002), after whom it is named.
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.
Band keratopathy has several causes. These causes include uveitis, interstitial keratitis, superficial keratitis, phthisis, sarcoidosis, trauma, intraocular silicone oil, systemic diseases (high levels of calcium in the blood, vitamin D intoxication, Fanconi's Syndrome, low levels of phosphorus in the blood, gout, milk-alkali syndrome, myotonic dystrophy, and chronic mercury exposure).
Degenerative diseases such as pterygiums and Terrien's marginal degeneration may also be responsible. [1] Traumatic causes of CNV include ulceration, alkali burns, and stem cell deficiency. [1] One of the most common causes of corneal neovascularization is iatrogenic pathology from extended contact lens wear.
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.
