The difference between trachoma and conjunctival concretions.
Trachoma is caused by Chlamydia infection, while eye concretions are generally caused by chronic inflammation leading to lipid accumulation. When the eyelids show symptoms of trachoma, proliferative follicles and proliferative tissues in the eyelids form cobblestone changes. The concretions are white and located subconjunctivally, generally deep enough not to affect the eyes, but if superficial, they protrude into the palpebral conjunctiva and can cause certain wear to the eyes. Symptoms such as a foreign body sensation, burning sensation, and increased secretions can result from both trachoma and eye concretions. For treatment, eye drops are used for trachoma, and the eye concretions are removed under topical anesthesia, which alleviates the symptoms.
