Pinguecula
Pinguecula is a common, benign growth on the conjunctiva, the clear membrane covering the white part of the eye. It appears as a yellowish, slightly raised bump near the edge of the cornea. Pingueculae are typically harmless and do not spread to other parts of the eye.
Symptoms:
· Yellowish raised bump on the white of the eye.
· Redness or mild irritation.
· Dry or gritty sensation.
· Burning or itching.
· Watery eyes.
· Discomfort with contact lens wear.
Causes: Pinguecula is strongly associated with long-term environmental exposure and ocular surface irritation.
· Ultraviolet (UV) light exposure: Chronic exposure to sunlight is a major contributing factor in the development of pinguecula.
· Environmental irritants: Wind, dust, smoke, and dry climates can irritate the conjunctiva and contribute to tissue changes.
· Age and repeated exposure: Pingueculae are more common in adults who have spent many years outdoors without consistent eye protection.
· Contact lens wear: Contact lenses may worsen irritation in individuals with pinguecula.
Diagnosis and Tests: Diagnosis is made during a comprehensive eye examination. A slit-lamp examination allows detailed assessment of the growth’s size, shape, and location. Pinguecula is clinically distinguishable from pterygium, which extends onto the cornea.
Management and Treatment:
· Observation and supportive care: If asymptomatic, no treatment is required. Regular monitoring may be recommended.
· Symptom relief: Lubricating artificial tears and avoidance of environmental irritants help relieve discomfort.
· Anti-inflammatory treatment: Short-term anti-inflammatory eye drops may be prescribed if inflammation (pingueculitis) develops.
· Surgical intervention: Surgery is rarely required and is generally reserved for significant discomfort, cosmetic concerns, or interference with contact lens wear.
Prognosis:
· The prognosis for conjunctival cysts is excellent.
· Most remain stable or resolve without complications.
· Removal procedures generally result in full recovery.
· Recurrence may occur, especially if underlying irritation persists.
Prevention: Protective measures help reduce risk and progression:
· Wear UV-protective sunglasses outdoors.
· Use wide-brimmed hats in bright sunlight.
· Protecting eyes from wind and dust.
· Use lubricating drops in dry environments.
When Should I See My Healthcare Provider? Seek evaluation if irritation persists, redness worsens, or vision becomes blurry.
When Should I Go to the Emergency Room? Emergency care is necessary for sudden vision loss, severe eye pain, or signs of infection.
What Questions Should I Ask My Healthcare Provider?:
· Is this definitely a pinguecula?
· How can I reduce irritation?
· Could this develop into pterygium?
· Do I need protective eyewear?
Key Takeaways:
· Pinguecula is a benign conjunctival growth.
· UV exposure and environmental irritation are key risk factors.
· Most cases require no treatment.
· Lubrication and protection reduce symptoms.
· Surgery is rarely needed.
