Pinguecula

A yellow nodule on the white of the eye — an accurate diagnosis matters

Pinguecula is a condition in which part of the conjunctiva (the white of the eye) degenerates into a raised, yellowish nodule.

It usually doesn't affect vision but can cause a foreign-body sensation or redness, and since it looks similar to pterygium it is easily confused with it, so an accurate diagnosis is needed.

Pinguecula

Main causes of pinguecula

  • UV exposure

    UV exposure

    Prolonged unprotected UV exposure degenerates conjunctival tissue, forming protein clumps.

  • Chronic external irritation

    Chronic external irritation

    Fine dust, wind, dry air and other irritants make it likely to develop when they continually stress the conjunctiva.

  • Aging & fatigue

    Aging & fatigue

    Can develop as aging and ocular irritation accumulate; redness and foreign-body sensation worsen with fatigue or inflammation.

Tailored pinguecula care solutions

Stepwise management based on accurate diagnosis matters more than rushing to surgery

1

Inflammation control (medication)

When 'pingueculitis' occurs — the pinguecula reddening and swelling — symptom-matched eye drops relieve the inflammation and discomfort.

2

Cosmetic removal

If appearance causes severe stress, surgical removal can be considered — decide carefully after a thorough consultation with an experienced specialist.

3

Progression-control care

Reduce friction with artificial tears and adopt UV-blocking habits so that tissue degeneration does not worsen, with careful daily management.
