Overview
A common benign yellow-white conjunctival degeneration adjacent to the limbus, usually nasal or temporal in the interpalpebral zone. It remains on the conjunctiva and does not grow onto the cornea; that distinction separates it from pterygium. Most cases need reassurance, UV/wind/dust protection, and lubrication. Inflamed pinguecula (pingueculitis) may cause localised redness and irritation. The safety task is to recognise atypical, raised, leukoplakic, pigmented, vascular, rapidly changing, painful, or cornea-involving lesions and route them away from the benign pinguecula pathway.
Recognition
Symptoms: what patients report
- Often asymptomatic and noticed incidentally.
- Foreign-body sensation, grittiness, dryness, or mild irritation.
- Localised redness around the lesion during pingueculitis.
- Symptoms may worsen with UV exposure, wind, dust, dry air, smoke, or prolonged screen-related dryness.
- Vision is usually unchanged unless tear-film disruption or another diagnosis is present.
Signs: what the examination shows
- Yellow-white, slightly raised conjunctival lesion adjacent to the limbus, usually nasal or temporal.
- Lesion remains conjunctival and does not cross onto the cornea.
- Localised conjunctival injection may surround the lesion when inflamed.
- Surface is usually smooth and clinically stable.
- No corneal infiltrate, no epithelial defect over an infiltrate, no AC reaction, and no significant discharge in uncomplicated disease.
- Atypical features include leukoplakia, feeder vessels, irregular borders, pigmentation, rapid growth, raised gelatinous surface, or corneal extension.
