The patient has a pimple on the white eyeball, which may be caused by blepharospasm, pterygium, vesicular conjunctivitis and so on.
1. Blepharophimosis: This condition is common in middle-aged and elderly patients, usually for those who have been engaged in outdoor work for a long time or receive direct sunlight. It is usually a white protrusion caused by the growth of conjunctival tissue degeneration. It usually does not affect the patient’s vision, but the patient may experience a foreign body sensation in the eye.
2. Pterygium: In the resting phase, the pterygium is not congested and is white or pink in color. In the active stage, the pterygium will have localized blood vessel dilation and appear flesh red, so it looks like a pimple on the patient’s white eyeball.
3. Vesicular conjunctivitis: Vesicular conjunctivitis is an inflammation caused by the body’s own immune response, which can grow in any part of the white eyeballs, with localized vasodilatation and vesicular elevation, and the patient may suffer from itchy eyes, foreign body sensation and other uncomfortable symptoms.
It is recommended that patients with pimples on the white eyeballs and other discomforts should consult the hospital in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
