ABSTRACT
AIM: To observe the curative effect of PDT combined with intravitreal injection of ranibizumab treatment for age-related macular degeneration with choroidal neovascularization ( CNV) . METHODS:In accordance with the inclusion criteria, by indocyanine green choroidalangiography ( ICGA ) and optical coherence tomography ( OCT ) examination confirmed the diagnosis of macular CNV in 27 patients (27 eyes), treated with PDT 3 ~ 7d professional intravitreal injection of ranibizumab. At 1, 3, 6mo after treatment, the results of best corrected visual acuity (BCVA), FFA, ICGA, OCT examination and complications were observed. RESULTS: The BCVA improved in 17 eyes ( 63%) , stable in 6 eyes ( 22%) , and decreased in 4 eyes ( 15%) . Before treatment, the average leakage area was 1 005. 69±105. 47μm, it were 875. 54 ± 103. 27μm, and 423. 37 ±79.68μm at 1 and 3mo after treatment, there were significant differences compared with before treatment ( PCONCLUSION: The method that PDT closed CNV combined with intravitreal injection of ranibizumab can effectively block angiogenesis recurrence, reduce the number of PDT treatment again and complications, improve the therapeutic effect.
