Abstract:
Objective To investigate the preoperative design and application of the minimum foveolar translocation distance and angle of macular translocation. Methods The fundus fluorescein and indocyanine green angiographies were performed on 53 eyes of 53 patients with classic subfoveal choroidal neovascularization (SCNV), including 42 with exudative age-related macular degeneration and 11 with high myopic macular degeneration. The actual area of macular SCNV and the minimum foveolar translocation distance and angle were analyzed. Results The actual area of SCNV was 0.39~18.00 mm 2 with the mean of (3.08?3.22) mm 2. The designed minimum superior translocation distance was 67~2 240 ?m with the mean of (845.72?425.23) ?m;the minimum designed minimum inferior translocation distance was 53~ 2 430 ?m with the mean of (912.17?547.77) ?m. The minimum designed superior translocation angle was 1~32? with the mean of (13.23?6.68)?;the minimum designed inferior translocation angle was 1~35? with the mean of (14.06?8.46)?. The individual difference of the minimum designed superior and inferior translocation distance was more than 500 ?m in 16 eyes (30.19%), and the difference of translocation angle was more than 10? in 11(20.75%). Conclusion Preoperative design of minimum translocation distance and angle of macular translocation may be helpful to choose the operation program.
