There is a yellowish mass on the white part of the eye.

A yellowish mass appearing on the white part of the eye may be caused by conditions such as cataracts, pinguecula, or macular disease.

1. Cataracts

Cataracts cause rapid breakdown of lens proteins and fibers, with resulting substances accumulating locally to form yellowish patches. For mild cases, patients may follow medical advice to use medications such as aniodipine eye drops, phacolysin eye drops, or ketorolac tromethamine eye drops for controlled management. In severe cases, surgical treatments such as phacoemulsification cataract extraction and intraocular lens implantation may be considered.

2. Pinguecula

Prolonged exposure of the conjunctival tissue to external factors such as ultraviolet radiation, dust pollution, or welding fumes can lead to conjunctival degeneration and the formation of yellowish spots in the white area of the eye. Under a doctor's guidance, patients may use medications such as fluorometholone eye drops, taurine eye drops, or reduced glutathione eye drops to reduce irritation from external factors and help prevent further progression of the condition.

3. Macular Disease

This condition affects the macular region of the retina, causing symptoms such as yellowing of the white of the eye, blurred vision, and distorted visual perception. As directed by a physician, patients may use medications such as ranibizumab injection, sodium carboxymethylcellulose eye drops, or diclofenac sodium eye drops to slow the progression of macular disease and alleviate the aforementioned symptoms.

Other conditions, such as retinal arteriosclerosis, may also cause similar symptoms. Patients should seek hospital evaluation and diagnosis to confirm the underlying cause before initiating appropriate treatment.
