Blepharoconjunctivitis

**Blepharoconjunctivitis** is an ophthalmic condition characterized by concurrent inflammation of the eyelid margins and the conjunctiva.

Affecting pediatric and adult populations, it often arises as an extension of anterior or posterior blepharitis—frequently driven by meibomian gland dysfunction, bacterial colonization (predominantly *Staphylococcus* species), viral infections, parasitic infestation, or allergic hypersensitivity.

This localized dysbiosis and inflammatory response disrupt tear film stability and epithelial integrity across the continuous ocular surface.

Defining clinical features include eyelid margin erythema, crusting or collarettes along the eyelashes, conjunctival hyperemia, ocular discharge, pruritus, burning, and a foreign body sensation, which may be complicated by secondary superficial keratitis.
