PHLYCTENULAR KERATITIS Meaning and
Definition
-
Phlyctenular keratitis is a medical condition in which small, raised lesions or nodules develop on the cornea, the transparent front part of the eye. These lesions are known as phlyctenules and are typically caused by a hypersensitivity reaction to certain antigens. This condition most commonly affects children and is often associated with underlying systemic conditions such as tuberculosis, staphylococcal infection, or other chronic infections.
The development of phlyctenular keratitis is thought to occur when the immune system reacts to antigens that are present either on the cornea or in the surrounding tissues. This immunological response leads to the formation of phlyctenules, which can cause significant eye discomfort, redness, tearing, and sensitivity to light. In some cases, the phlyctenules may rupture, resulting in the formation of corneal ulcers.
Treatment for phlyctenular keratitis typically involves addressing the underlying cause, such as administering appropriate antibiotics for bacterial infections or antitubercular medications for tuberculosis. Topical corticosteroids may also be prescribed to reduce inflammation and minimize the discomfort associated with the condition. It is important to monitor the condition carefully, as severe or recurrent cases may require more intensive treatment or referral to an ophthalmologist for specialized care.
Overall, phlyctenular keratitis is a relatively rare but potentially serious condition that affects the cornea of the eye. Prompt diagnosis and appropriate management are crucial to prevent complications and preserve vision.

Etymology of PHLYCTENULAR KERATITIS
The term "phlyctenular keratitis" is derived from two components: "phlyctenular" and "keratitis".
1. Phlyctenular: The word "phlyctenular" originated from the Greek word "phlyktaino" (φλυκταίνω), which means "to form small blisters or pustules". Phlyctenular refers to the characteristic small blisters or nodules that develop in certain inflammatory conditions.
2. Keratitis: The term "keratitis" comes from the Greek word "keras" (κέρας), which means "horn" or "cornea", and the suffix "-itis", which denotes inflammation. Therefore, "keratitis" can be translated as "inflammation of the cornea".
