A white spot on the patient’s eye may be caused by keratitis, corneal scarring, eye stones, etc. The patient can follow the doctor’s instructions to use medication or surgical treatment to alleviate the eye discomfort, and the specific treatment is related to the patient’s condition. Patients with keratitis may experience eye pain, photophobia, tearing, eyelid spasms and other discomforts. Inflammation in the corneal tissues can lead to clouding and edema of the otherwise clear cornea, reducing its transparency and resulting in the appearance of white patches on the patient’s eyeballs. Patients can use antibiotics such as tobramycin eye drops as prescribed by their doctor to reduce the inflammatory response and promote the recovery of corneal lesions. Corneal scarring is caused by trauma to the cornea or untimely treatment of inflammation, resulting in the formation of scarring during the process of local tissue repair, which also looks like white patches in appearance. If it affects the patient’s vision, the patient may be eligible for a corneal transplant to improve vision. Patients with ocular calculi may also have white spots on top of their eyes. The etiology is unknown, and may be related to long-term work in sandy areas and high intraocular secretions. Long-term stimulation by sand and wind can gradually form ocular calculi, and patients can undergo ocular calculi removal under a slit lamp after surface anesthesia in order to alleviate ocular discomfort. Patients with white spots on the eyes are advised to seek prompt medical attention to assess their condition and undergo treatment under the guidance of a doctor.
