A 20 years female is diagnosed to have pterygium. She does not have any clinical symptoms except lor cosmetic concern. Treatment should be –
**Core Concept**
Pterygium is a common ocular surface disorder characterized by the growth of a fibrovascular tissue on the conjunctiva, often covering the cornea. This condition is more prevalent in individuals exposed to high levels of ultraviolet radiation, particularly in tropical or subtropical regions.
**Why the Correct Answer is Right**
The management of pterygium typically involves surgical excision, especially when the growth causes significant cosmetic concern or impairs vision. The surgical approach may include a conjunctival autograft or a simple excision of the pterygium. The primary goal is to remove the affected tissue while preserving the underlying corneal integrity. In cases where the pterygium is recurrent, additional treatments such as beta irradiation or mitomycin C application may be considered to prevent regrowth.
**Why Each Wrong Option is Incorrect**
**Option A:** Medical management with topical corticosteroids or immunosuppressive agents is not the primary treatment for pterygium, as these options may not effectively prevent recurrence.
**Option B:** Conservative management with sunglasses and avoidance of UV radiation exposure may be beneficial in preventing pterygium growth, but it is not an effective treatment option for an existing pterygium causing cosmetic concern.
**Option C:** Laser therapy is not a standard treatment for pterygium, as it may not effectively remove the affected tissue or prevent recurrence.
**Clinical Pearl / High-Yield Fact**
Pterygium is often associated with UV radiation exposure, and individuals with a history of prolonged exposure to the sun, particularly in tropical regions, are at a higher risk of developing this condition.
**Correct Answer: C. Laser therapy is not a standard treatment for pterygium, as it may not effectively remove the affected tissue or prevent recurrence.**
