摘　　要：目的 探讨老年人黄斑光敏感度下降的相关因素。方法 应用国产APS-6000B型自动视野分析仪，对120例240眼的老年人进行0°～30°中心视野全阈值检测。其中老年黄斑变性组50眼，青光眼组46眼，糖尿病组44眼，高血压病组40眼，分别与对照组60眼比较。结果 黄斑变性组、青光眼组和糖尿病组的黄斑光敏感度均有不同程度的下降，而高血压病组与对照组相比差异无统计学意义。结论 老年人中老年黄斑变性、青光眼和糖尿病可能是造成老年人黄斑光敏感度下降的重要原因。其发病机制可能与细胞的凋亡、微循环障碍和血流动力学的改变有关。Objective To evaluate the reasons of the decrease of macular light sensitivity in senile people. Methods Two hundred and forty eyes were detected on light sensitivity of central visual field with APS -6000 automatic primary. Age -related maculopathy ,glaucoma,diabetes mellitus and hypertension groups were 50,46, 44 and 40 eyes,respectively. They were all compared with the control （60 eyes） one by one. Results Patients with age -related maculopathy, glaucoma and diabetes mellitus had the reduction of macular light sensitivity, and cases with hypertension were same as the control. There were statistically significant differences in four groups except the hypertension group. Conclusion There may be many reasons involved in the decrease of the macular light sensitivity in senile people;but the age- related and the henlorheological changes may be related with it.
