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.

Main causes of pinguecula

UV exposure
Prolonged unprotected UV exposure degenerates conjunctival tissue, forming protein clumps.
Chronic external irritation
Fine dust, wind, dry air and other irritants make it likely to develop when they continually stress the conjunctiva.
Aging & fatigue
A natural part of ocular aging — symptoms become more pronounced when overwork or inflammation is involved.

Tailored pinguecula care solutions

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

Inflammation control (medication)

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

Cosmetic removal

If appearance causes severe stress, surgical removal can be considered. However, scarring or pseudo-pterygium aftereffects are possible, so decide carefully after a thorough consultation with an experienced specialist.

Progression-control care

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