What is Trans-scleral Cyclophotocoagulation?

The eye contains a liquid called aqueous humor. Excess production or inadequate drainage of this fluid increases the pressure in the eye (intraocular pressure). Trans-scleral cyclophotocoagulation is a laser treatment performed to lower the pressure caused by the overproduction of aqueous humor. The treatment is usually considered only when medications, eye drops, and other surgical procedures are inappropriate or have failed to provide good results and vision is already very poor.

Trans-scleral cyclophotocoagulation is performed under local anesthesia and takes less than 15 minutes to complete. A laser beam is directed on the ciliary body, the structure that produces aqueous humor. This partially destroys the ciliary body, normalizing the pressure inside the eye, while retaining enough ciliary body to produce some amount of fluid. After the surgery, your eye will be bandaged and your doctor may prescribe eye drops to reduce pain.

Like all surgeries, Trans-scleral Cyclophotocoagulation may be associated with complications such as:

  • Blurred vision for a few days
  • Bleeding in the eye
  • Drastic rise or fall in eye pressure
  • Inflammation of the eye
