Ocular calculi, or white granules that occur mostly in the lid conjunctiva. They are hard but not real stones, formed by the accumulation of epithelial cells and secretions from the conjunctiva. Ocular calculi are usually found in adults, mainly in patients with trachoma or chronic conjunctivitis, which are chronic eye diseases. They are more common in the upper eyelid, where small hard white dots, like grains of rice, protrude from the lid conjunctiva, either in scattered dots or in clusters. When the inflammation reaches a certain level and gradually exposes itself on the surface of the conjunctiva, there will be a foreign body sensation, even causing corneal abrasions, and in severe cases, corneal erosion. The treatment of ocular calculi is relatively simple. When the patient has obvious symptoms, the stone is removed with a sterile syringe needle under surface anesthesia by a medical professional. As mentioned above, eye stones should be treated promptly, especially in the early stages, and promptly when eye discomfort occurs. After treatment, it is also important to maintain eye hygiene to prevent chronic inflammation of the eye.
