摘　　要：目的　研究病理性近视黄斑区脉络膜新生血管的临床特点及发病机制。方法　对1 2 1只眼的高度近视患者作视力、眼底检查及荧光素眼底血管造影检查 ,并分析其临床特点。结果　观察病例中病理性近视黄斑区视网膜下新生血管发生的构成比为 3 0 6%。病理性近视黄斑区视网膜下新生血管与近视度数、漆样裂纹形成、黄斑区缺血等因素有关。结论　发生于中心凹的新生血管出血是严重影响视力的主要原因。OBJECTIVE To study mechanism and clinical characteristics of subretinal neovascularization in macular zone of patients with pathologic myopiaMETHODS Visual acuity and fundus were examined, and fundus fluorescein angiography(FFA) was performed in 121 eyes with pathological myopia Data of these examinations were analyzed statistically RESULTS Ratio of subretinal neovascularization found in macular zone of the patients with pathological myopia was 306%Subretinal neovascularization of macular zone in the patients with pathologic myopia is interrelated with ocular diopter, lacquer cracks, and disruption of macular circulation CONCLUSION Fovea hemorrhage caused by subretinal neovascularization is primary reason, which result in impairment of visual acuity sharply
