What causes brown spots in the white part of the eye?

The white part of the eye, also known as the sclera, may show brownish discoloration due to conditions such as retinitis pigmentosa, subconjunctival hemorrhage, or pinguecula. Specific explanations are as follows:

1. Retinitis Pigmentosa

Retinitis pigmentosa is usually influenced by genetic factors. Degenerative changes in the retinal pigment epithelium may lead to brownish appearances in the sclera, potentially affecting vision. Patients should follow medical advice and use visual aids to alleviate symptoms.

2. Subconjunctival Hemorrhage

Trauma to the conjunctiva or dilation of conjunctival blood vessels may cause vessel rupture, leading to the aforementioned symptoms. Patients may follow medical guidance to use medications such as levofloxacin hydrochloride ophthalmic solution and cefixime capsules to prevent ocular infection.

3. Pinguecula

Pinguecula may be triggered by long-term exposure of the eyes to dust or ultraviolet radiation. Under stimulation from these factors, elevated lesions may develop on the scleral area, causing this symptom. Patients can seek treatment at a qualified medical facility through surgical removal of the pinguecula under microscopic guidance.

In addition, brownish spots in the white of the eye could also result from degenerative changes of the conjunctiva or congenital abnormalities. It is recommended that patients ensure adequate eye rest during treatment.
