The word "phlyctenular" is not a commonly used term, but it is found in medical literature to describe a type of inflammation in the eye. The spelling of this word can be explained using the International Phonetic Alphabet as /flɪkˈtɛnjʊlər/. The "ph" at the beginning of the word is pronounced as an "f" sound, while the "y" is pronounced as an "i" sound. The "ct" in the middle of the word is pronounced as "k", and the final "ar" is pronounced as "ər".
Phlyctenular is an adjective that refers to a medical condition related to the appearance of small, inflammatory nodules or pustules on the surface of the eye or skin. Derived from the noun "phlyctenule," this term typically describes a specific type of inflammation known as phlyctenular keratoconjunctivitis.
In ophthalmology, phlyctenular keratoconjunctivitis is an inflammatory condition affecting the conjunctiva and cornea of the eye. It is characterized by the formation of small, tender, and raised bumps called phlyctenules on the conjunctiva—a thin, transparent membrane that covers the front surface of the eye. These phlyctenules may also develop on the cornea, the clear dome-like structure that covers the iris and pupil.
Phlyctenular keratoconjunctivitis usually occurs as a result of an immune response triggered by an allergic reaction or an infection, typically staphylococcal bacteria or tuberculosis. Symptoms of this condition commonly include eye redness, itching, excessive tearing, and sensitivity to light. In severe cases, it may cause blurry vision and corneal ulcers. Treatment typically involves addressing the underlying cause, such as administering antibiotics or prescribed eye drops, and managing the associated inflammation. Additionally, artificial tears, cool compresses, and avoiding known allergens may help alleviate symptoms.
Overall, phlyctenular describes the clinical presentation of inflammation in the form of small, raised lesions on the eye or skin and is most frequently used within the context of phlyctenular keratoconjunctivitis.

The word "phlyctenular" is derived from the Latin word "phlyctaena" which means "blister". The Latin term is ultimately derived from the Greek word "phluktaino", which also has the same meaning. The suffix "-ular" is used to indicate "pertaining to" or "resembling", hence "phlyctenular" refers to something that resembles or relates to blisters.
