Pinguecula

A yellow bump on the white of the eye not a simple irritation, but pinguecula.

It may not obstruct vision, but it is a yellow nodule you notice every time you look in the mirror.
Often confused with pterygium, Gangnam Tokyo Eye Clinic provides
accurate differential diagnosis and personalized management plans.

Pinguecula

What is Pinguecula?

It is a yellowish, raised nodule formed by the degeneration
of the conjunctival tissue on either side of the cornea, where protein and fat accumulate.

It commonly appears on the nasal side of the sclera and, unlike pterygium,
does not invade the cornea, which is the key difference.
Although it does not grow rapidly, inflammation caused by fatigue or irritation
can make it
appear more prominent as it becomes red and swollen.

Main Causes of Pinguecula

Pinguecula is a signal of 'irritation' sent by the eye.

1Inflammation Management (Medication)

When 'pingueculitis' occurs with redness and swelling around the pinguecula, eye drop treatment can provide rapid relief within 3-4 days.

2Cosmetic Removal Surgery

If there is no vision impairment but significant cosmetic stress, surgical removal may be considered. However, due to concerns about scarring or pseudo-pterygium complications, consultation with an experienced specialist is essential.

3Progression Control Care

Use artificial tears frequently to reduce friction, and make UV protection a daily habit to prevent worsening degeneration.
