- A physical examination can be done by your doctor using a slit lamp to diagnose a pterygium.
- Visual acuity test, Corneal topography and Photo documentation are some additional tests that may be required for diagnosing a pterygium
- Surgery is recommended to remove the pterygium if eye drops or ointments does not provide relief.

- The pterygium surgery is a minimally invasive surgery that generally takes 30 to 45 minutes.
- Sedation will be given to you to numb your eyes so that discomfort during surgery can be prevented.
- Then the surrounding areas will be cleaned by the doctor.
- The pterygium along with some associated conjunctiva tissue will be removed by the doctor.
- The pterygium will be replaced with a graft of associated membrane tissue once it is removed to prevent recurrent pterygium growths.
- Sutures or fibrin glue will be used by the doctor to secure the conjunctiva tissue graft in its place, once the pterygium is removed.
- The possibility of recurring pterygia will be reduced by this procedure.
- Dissolvable sutures can cause more discomfort postsurgery, and the recovery time can be extended for several weeks.
- Inflammation and discomfort can be reduced while the recovery time can be reduced to half using fibrin glue, compared to using sutures.
- Fibrin glue may carry the risk of transmitting viral infections and diseases as it is a blood derived product.
- Fibrin glue is also more expensive than sutures.
- Bare sclera technique to remove pterygia from the eye is another option, though it carries an increased risk of pterygium recurrence with it.
- The pterygium tissue will be removed without replacing it with a tissue graft which leaves the underlying white of the eye exposed to heal on its own.
- The risks from sutures or fibrin glue can be eliminated by using Bare sclera technique. However, there is a high chance of pterygium regrowth, and at a larger size.
