Purpose: Age related macular degeneration is the leading cause of visual loss in the developed world. Several methods of treatment have been used for choroidal neovascular membrane (CNV) in age related macular degeneration (AMD).The purpose of this study is to evaluate the clinical features, treatment results and complications of patients with occult choroidal neovascular membrane due to AMD treated with transpupillary thermo therapy (TTT). Methods: A prospective study was conducted at the Prince Charles Eye Unit (King Edward VII hospital, Windsor, UK, SL4 3DP) to evaluate the clinical features, treatment results and complications of patients with occult choroidal neovascular membrane due to AMD treated with transpupillary thermo therapy (TTT).20 patients were treated with TTT delivered over one to two sessions and followed up by clinical examination and fluorescein angiography for an average period of three months (range: 5- 20 months) Results: 4 patients (20%) showed objective improvement, 9 patients (45%) maintained their visual acuity at the same level and 7 patients (35%) showed deterioration of vision objectively. Conclusions: This preliminary study demonstrates that TTT appears to be an effective treatment for CNV. Longer follow up is necessary to assess for the recurrence of CNV.
