Conjunctival concretion refers to yellowish-white deposits that appear on the surface of the palpebral conjunctiva. This condition is commonly observed in patients with chronic conjunctivitis or in elderly individuals. The concretions are formed by coagulated desquamated epithelial cells and degenerated leukocytes. Patients are generally asymptomatic, and treatment is typically not required. If the concretion projects above the conjunctival surface, causing foreign body sensation or corneal abrasion, it can be removed under topical anesthesia using a foreign body needle or a fine blade.
