目的　用 Octopus- 12 3视野计黄斑阈值程序检测早期 AMD黄斑 10°光敏感度 ,探讨其对 AMD早期诊断的临床价值。方法　对早期 AMD患者 6 8眼 ,正常对照 40眼分别检测了中央 10°范围视网膜光敏度、Amsler表和 FFA检查。结果　早期 AMD病人与正常对照组比较 ML S有明显差异性。早期 AMD病人 ML S降低阳性率为 5 0 .77% ,Am sler表检查阳性率为 2 0 % ,FFA检查异常为 35 %。结论　 Octopus自动视野计黄斑阈值检查优于Amsler表中心视野检查及 FFA检查 ,可为 AMD的早期诊断提供有效的方法 Objective To detect the 10 ° photosensitivity of early AMD macula with Octopus-12 3 macular threshold program and to explore its clinical value in the early diagnosis of AMD. Methods Sixty-eight eyes of early AMD and 40 eyes of normal control were examined for central retinal photosensitivity in the 10 ° range, Amsler chart and FFA. Results Early AMD patients compared with the normal control group ML S significant difference. The positive rate of ML S in patients with early AMD was 50.77%, that of Am sler was 20%, and that of FFA was 35%. Conclusion Octopus auto-fluoroscopy is better than Amsler’s central visual field examination and FFA in detecting macular thrombosis, which may provide an effective method for the early diagnosis of AMD
