Pinguecula is a benign growth of the conjunctiva, the clear tissue that covers the white part of the eye. It usually appears as a yellowish, raised bump on the side of the cornea, often on the nasal side. It is commonly associated with exposure to sunlight, dust, and wind.
Causes:
- UV radiation: Prolonged exposure to sunlight is a primary cause.
- Environmental factors: Wind, dust, and dry conditions may contribute.
- Age: It tends to develop with age, especially in people over 40.
Management:
- Observation: Most cases don't require treatment unless symptoms occur.
- Artificial tears: For dryness or irritation.
- Steroid eye drops: If inflammation is present.
- Surgical removal: Rarely needed unless the pinguecula interferes with vision or causes significant discomfort.
Prevention:
- UV protection: Wearing sunglasses with UV protection to reduce sun exposure.
- Protective eyewear: In windy or dusty environments.
- Moisturizing eye drops: To prevent dryness and irritation.
Pinguecula is typically harmless, but if it causes discomfort or affects vision, it should be evaluated by an eye care professional.
