Conjunctival concretion

Chronic conjunctivitis (e.g. trachoma) and aging factor are two causes of conjunctival concretion, which will make the conjunctiva cellular degeneration to produce an epithelial inclusion cyst, filled with epithelial cells and keratin debris. After calcification, the conjunctival cyst hardens and forms a conjunctival concretion. Congenital conjunctival concretion condition is also more common.^{[citation needed]}

Conjunctival concretions can be single, also multiple, less confluent. There is no difference between the site of the occurrence on the upper and lower eyelid, nor right or left eye. The vast majority of concretions are in the conjunctival surface rather than deep. There is no difference in age for predilection or incidence of concretions, due to the causes of conjunctivitis, aging, and even congenital factor.^{[citation needed]}

For statistical purposes Conjunctival Concretion is classified under the World Health Organization's ICD-10 category of H11.129^[1] and the ICD-11 category of 9A61.6.^[2]

Conjunctival concretions can be seen easily by everting the eyelid. The projecting concretions can be removed if they are causing concerning symptoms. Removal can be performed by an eye doctor. Sometimes just a needle or a scalpel is used to remove the concretion under local light anesthesia of the conjunctiva in adults.^{[citation needed]}
