Transpupillary Thermotherapy (TTT) is a special form of Laser treatment for Choroidal Neo Vascular Membrane (CNVM) due to various causes like – Age related Macular Degeneration (AMD), High Myopia, idiopathic and post inflammatory. Transpupillary Thermotherapy (TTT) is a low energy, long exposure laser treatment using a special Diode laser. This gently heats up the tissues leading to closure of the abnormal new vessels (CNVM) with minimum or no damage to the surrounding normal tissue.

It is particularly indicated in a specific type of CNVM, i.e., the occult type. It is also a suitable alternative to the more expensive Photo Dynamic Therapy (PDT) laser. This procedure itself takes only a few minutes and is usually painless and without any significant side effects. Since there is no dye injected, there is no risk or special precautions for photosensitivity, and the patient can go back to normal routine after it.

TTT is very effective in stabilizing vision; though repeat treatment sessions may be needed for recurrent or persistent CNVM. The aim of the treatment is to try and preserve and stabilize the vision, and not to improve vision. A large number of patients achieve stabilization of vision; some of the patients may even notice some improvement in vision also. It is mandatory for the patients to maintain very regular follow up after this treatment, and monitor their vision regularly with the help of Amsler Grid.
