Milky white protrusions on the white globe of a patient’s eye can be caused by infection of the conjunctiva, immune response, hypersensitivity reaction, or post-traumatic scar repair. Milky white prominence on the white eyeball of a patient can be secondary to conjunctival inflammatory reaction due to conjunctival infection, immune or hypersensitivity reaction, etc. When conjunctivitis occurs, the patient may have conjunctival congestion and hyperplasia, which may lead to papillary hyperplasia and follicle formation, and the patient may have milky white prominence on the white eyeball. Ocular trauma patients with conjunctival scar repair or prolonged exposure of the conjunctiva leading to blepharospasm can also develop a milky white prominence of the white eyeball, the specific cause and treatment of which is recommended to consult an ophthalmology clinic. There are many reasons for the appearance of milky-white protrusions on the white eyeballs of patients, and the diagnosis should be made by slit-lamp microscopy and other ancillary examinations combined with the relevant medical history. It is recommended that patients with milky-white protrusions on the white eyeballs consult an ophthalmologist promptly for evaluation of their condition and treatment as prescribed by the doctor.
