Concretions appear to be epithelial inclusion cysts filled with epithelial and keratin debris, as well as mucopolysaccharide and mucin. They are seen as small, yellow-white dots in the palpebral conjunctiva of older patients or patients who have had chronic conjunctivitis. Concretions are almost always asymptomatic, but they may erode the overlying epithelium, causing foreign-body sensation. If symptomatic, concretions can be easily removed under topical anesthesia.
