Conjunctival diseases

The conjunctiva, with most of its surface exposed to the external environment, is susceptible to irritation from external factors and microbial infections, leading to various diseases. Conjunctival diseases encompass a broad category, with conjunctivitis being the most common, followed by degenerative diseases, and also including rare conjunctival tumors. Conjunctivitis: Common types include viral and bacterial conjunctivitis, allergic conjunctivitis, and conjunctivitis caused by foreign body irritation. Conjunctival degenerative diseases: These include pinguecula, pterygium, and conjunctival concretions. Conjunctival tumors: These include primary benign conjunctival tumors, such as conjunctival nevi and conjunctival papillomas, and primary malignant conjunctival tumors, such as conjunctival intraepithelial neoplasia and conjunctival squamous cell carcinoma.
