Phlyctenular pannus is a medical term used to describe a specific type of inflammation of the cornea that causes the formation of nodules or blisters. The term is spelled using the International Phonetic Alphabet (IPA) transcription system, which breaks down the pronunciation into individual sounds. The first syllable is pronounced "flɪk" (as in flick), the second syllable is pronounced "ten" (as in ten), and "ular" is pronounced "jʊlər." "Pannus" is pronounced "pænəs." Correct spelling is essential for medical professionals to ensure clear communication and accurate diagnoses.
Phlyctenular pannus is a medical term used to describe an inflammatory condition that affects the cornea, which is the clear, dome-shaped front part of the eye. This condition is characterized by the formation of small, painful sores called phlyctenules, which are typically located near the corneal margin.
The term "phlyctenular" refers to the presence of these phlyctenules, which are small bumps or vesicles filled with fluid. They usually develop as a result of an immune response, often in association with certain infections or allergies. Pannus, on the other hand, refers to the development of a vascularized tissue over the surface of the cornea.
Phlyctenular pannus is primarily seen in children and young adults, and it is commonly associated with conditions such as tuberculosis, staphylococcal infection, or chronic blepharitis. The presenting symptoms include eye redness, foreign body sensation, photophobia (sensitivity to light), and tearing.
If left untreated, phlyctenular pannus can lead to corneal scarring, which may result in long-term visual impairment. Therefore, prompt diagnosis and appropriate management are crucial. Treatment options include topical corticosteroids to reduce inflammation, antibiotics to address any underlying infection, and artificial tears to alleviate symptoms of dryness.
In conclusion, phlyctenular pannus is an inflammatory condition of the cornea characterized by the presence of small painful sores called phlyctenules. It requires immediate medical attention to prevent potential complications and preserve visual function.

The word "phlyctenular pannus" is a medical term used to describe a specific eye condition. To understand its etymology, let's break down the word:
1. Phlyctenular: This term comes from the Greek word "phlyktein", which means "to blister" or "to form a blister". In medical terminology, it refers to the formation of small blisters or pustules on the skin or mucous membranes.
2. Pannus: This term originates from Latin and means "a cloth" or "a sheet". In ophthalmology, pannus refers to a condition where excessive vascular tissue grows over the cornea.
Therefore, combining these two terms, "phlyctenular pannus" describes an eye condition where small blisters (phlyctenules) form, which can eventually lead to the growth of excessive vascular tissue on the cornea.
