Objective To evaluate the efficacy and safety of photodynamic therapy (PDT) combined with intravitreal injection of bevacizumab for choroidal neovas cularization (CNV) caused by age-related macular degeneration (AMD). Methods A total of 21 eyes of 21 patients with AMD, which was diagnosed by examination of visual acuity, intraocular pressure, ocular fundus, fundus color photography, fundus fluorescein angiography(FFA), indocyanine green angiography(ICGA)and optic coherence tomography(OCT), were underwent PDT combined with intravitreal injection of Bevacizumab. The patients, 15 males (15 eyes) and 6 females (6 eyes), aged from 56 to 78 years, with the average of 68.6 years. The best corrected visual acuity:counting fingers/10cm0.9, logMAR was 1.04  plusmn; 0.41.CNV located in below or side central fovea of macula. There was obvious leakage of fluorescein which examined by FFA and ICGA. The average of retinal thickness of macular foveal was (258.91  plusmn; 78.66) mu;m. The treatment method of PDT has to according to the way of PDT for TAP and Verteporfin PDT for VIP. Intravitreal infection with 1.5mg bevacizumab was performed after three days under surface anesthesia. Follow-up time was 1, 3, 6, 12 months after the treatment. Results At last visit, the best-corrected visual acuity:counting fingers/10 cm 1.5, logMAR was 1.04 plusmn;0.41, and the differences are statistically significant compared with before. The BCVA improved four or more lines in 6 eyes (28.57%), improved two to four lines in 9 eyes (42.86%), stabilized ( plusmn;1 line or no change) in 6 eyes (28.57%) and decreased in none. The average intraocular pressure was (15.20 plusmn;2.41)mmHg after surgery, and the differences was not statistically significant compared with before(P>0.05). FFA and ICGA showed CNV complete closure in 13 eyes (61.90 %), partial closure in 8 eyes (38.10%). The average of retinal thickness of mac ular foveal was(127.38 plusmn;20.14)  mu;m (P<0.01). Conclusion Combining treatment with PDT and intravitreal injection of Bevacizumab is safe and effective for CNV which caused by AMD. It has significant improvement in BCVA, leakage of CNV and retinal edema. (Chin J Ocul Fundus Dis,2008,24:164-167)
