The loss of vision with fungal keratitis can be quite disabling in terms of economic impact and social consequences. Many people come with fungal keratitis in the only eye and thus become blind due to the disease. The lack of education and proper eye protection in such cases is evidently responsible for their plight. [citation needed]
Corneal ulcers are painful due to nerve exposure, and can cause tearing, squinting, and vision loss of the eye. [ 2 ] [ 3 ] There may also be signs of anterior uveitis , such as miosis (small pupil), aqueous flare (protein in the aqueous humour ), and redness of the eye.
Antibody responses against the viral antigen expression in the stroma can trigger a massive immune response in the eye. The response may result in the destruction of the corneal stroma, [3] resulting in loss of vision due to opacification of the cornea. This is known as immune-mediated stromal keratitis. HSV infection is very common in humans.
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 ...
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.
The symptoms classically attributed to AK include decreased or blurred vision, sensitivity to light (photophobia), redness of the eye (conjunctival hyperemia), and pain out of proportion to physical exam findings. [15] [7] Another clinical feature that can distinguish Acanthamoeba from bacterial causes of keratitis is a lack of discharge from ...
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.

In case of severe vision loss, treatment of choice is penetrating keratoplasty. [ 17 ] Peters anomaly : [ 18 ] Peters anomaly, also known as iridocorneal adhesions or keratolenticular adhesions, is a posterior corneal defect with an overlying stromal opacity, often accompanied by adherent iris strands (Peters anomaly type 1).
