A white bump on the inner corner of the patient’s eye may be caused by conjunctival disease and lacrimal sac disease. 1. Conjunctival diseases: patients with blepharophimosis, pterygium and other conjunctival diseases may have white bumps in the inner corners of the eyes. A triangular, slightly elevated plaque with a triangular base toward the cornea appears in the bulbar conjunctiva near the corneal limbus at the site of the blepharospasm. Pterygium is a redundant organism that may appear as an elevated lesion on the cornea at the beginning of the symptoms. 2. Lacrimal sac disease: Lacrimal sac disease includes dacryocystitis, dacryocystic cyst, etc. Patients may have elevated lesions in the lacrimal sac area, and patients may have a slight swelling sensation, and a painful sensation when they press gently with their fingers. Dacryocystic cysts present as a cystic mass in the lacrimal sac area, and can also be accompanied by tearing, pus spillage, and other discomforts. Patients with white bumps in the eye are advised to seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
