Phlyctenular Conjunctivitis Association
Phlyctenular conjunctivitis is an allergic-type reaction that occurs on the conjunctiva, often appearing as small, yellowish-white nodules or bumps (phlyctenules).
Key Association: This condition is primarily associated with bacterial hypersensitivity, most commonly seen in individuals with latent or active Tuberculosis.
The immune system reacts to bacterial antigens, leading to inflammation and the formation of phlyctenules. While other conditions can cause conjunctivitis, Tuberculosis is the classic association for phlyctenular presentations.
- Tuberculosis: Primary association due to delayed hypersensitivity reaction to tuberculoprotein.
- Syphilis: Less commonly associated with phlyctenular conjunctivitis compared to Tuberculosis.
- Stevens Johnson syndrome: A severe mucocutaneous reaction, different presentation.
- Leprosy: Can cause various ocular manifestations, but not the typical cause of phlyctenular conjunctivitis.
Therefore, Tuberculosis is the most recognized condition linked to phlyctenular conjunctivitis.
