Abstract: The purpose of present study is to evaluate the efficacy of TTT in treatment of myopic choroidal nonvascular membranes (SNVMs). The study included 25 eyes of 25 different patients all suffering from myopic SNVMs. Another 10 eyes of 10 patients were not treated by TTT and were used as control. Marked improvement in the visual acuity of patients suffering from myopic SNVMs in 80% of cases. In the control group, 70% of cases showed deterioration in their VA, whereas the rest 30% remained unchanged. TTT is an effective method in treating myopic SNVMs, as well as an adjuvant therapy for other treatment modalities as PDT. (Photodynamic therapy).
