Pinguecula (pin gwe'
cue la)
A pinguecula is a benign, yellowish
growth that forms on the conjunctiva They usually grow near the cornea
on the nasal side. Pingueculae (plural form of pinguecula) are thought
to be caused by ultraviolet light and are most common among people who
spend a great deal of time outdoors.
This growth does not affect
vision, but may cause irritation if it becomes elevated. In rare cases,
the pinguecula may gradually extend over the cornea, forming
a pterygium.
SIGNS AND SYMPTOMS
Pingueculae are harmless
growths and rarely cause symptoms.
• Yellowish, raised area on the
conjunctiva
• Irritation and scratchiness
• Dry eye
• Occasional
inflammation of the conjunctiva
• Redness if the area becomes
irritated
DETECTION AND DIAGNOSIS
Pingueculae can often be seen
with the naked eye; however, the doctor diagnoses the growth with a
careful examination with a slit lamp microscope.
TREATMENT
Because of their benign nature, pingueculae rarely require treatment.
Occasionally, the growth may become inflamed, causing irritation and
dryness. The doctor may prescribe artificial tears for lubrication and
mild anti-inflammatory medication to reduce swelling.
