Eye Disease

Pinguecula Pinguecula

A nodule that catches your eye in the mirror —
accurate diagnosis comes first

A yellow nodule that doesn't block vision but causes
foreign-body sensation and redness.

Easily confused with pterygium due to appearance,

so get clear differential diagnosis at Shinsegae
for the right care solution.

3 main causes of pinguecula

Strong UV exposure
Prolonged unprotected UV exposure
degenerates conjunctival tissue, forming protein clumps.
Chronic irritation
Fine dust, wind, dry air and other irritants
continually stress the conjunctiva.
Aging & fatigue
A natural part of ocular aging —
symptoms intensify with overwork or inflammation.

Pinguecula care matched to symptoms

Stepwise management based on accurate diagnosis matters more than rushed surgery

Inflammation control (medication)

For "pingueculitis" — when the pinguecula reddens and swells —
symptom-matched eye drops calm the inflammation
within 3-4 days.

Cosmetic removal

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

Progression-control care

Artificial tears reduce friction
and UV-blocking habits prevent
further tissue degeneration —
careful daily management.
