H11.053

Clinical Causes: Excessive exposure to sunlight and ultraviolet (UV) radiation Chronic eye irritation from dust, wind, or pollution Genetic predisposition in some individuals Environmental factors contributing to conjunctival changes

Key Symptoms: Gradual growth of a fleshy, pinkish tissue on the conjunctiva near the cornea Raised, thickened tissue that extends onto the corneal surface Burning sensation or eye irritation Redness and inflammation around the affected area Possible visual disturbances if the growth encroaches on the cornea Typically bilateral, affecting both eyes progressively over time

Diagnosis Path: Diagnosis of peripheral pterygium involves a thorough eye examination by an eye care professional. The clinician will examine the conjunctiva and cornea, noting the size, location, and appearance of the growth. Slit-lamp microscopy helps in assessing the extent of tissue involvement. Additional tests are usually not necessary but may include careful measurement of the growth's progression over time to monitor changes. No laboratory tests are typically required for diagnosis.

Treatment Protocols: Management of peripheral pterygium depends on its size, growth rate, and effects on vision or comfort. Common approaches include: - Observation: Small, asymptomatic pterygia may simply be monitored regularly. - Medical treatment: Use of lubricating eye drops or anti-inflammatory medications can alleviate symptoms but do not prevent growth. - Surgical removal: Indicated if the pterygium causes significant visual impairment, discomfort, or cosmetic concerns. Surgery involves excision of the growth, often with adjunct procedures to reduce recurrence. - Postoperative care: Includes anti-inflammatory eye drops and follow-up visits to monitor healing and prevent recurrence. Prevention strategies stress protecting eyes from UV radiation through sunglasses and hats, reducing exposure to irritants, and wearing protective eyewear in harsh environments.
