目的:探讨眼底荧光素血管造影(fundus fluorescein angiog-raphy, FFA)在年龄相关性黄斑变性(age-related macular degeneration, AMD)患者中的特征及临床意义。方法:用日本Nikon NF-505眼底照相机对112例149眼进行FFA检查。结果:在149眼中,萎缩型90眼(60.4%),渗出型59眼(39.6%),依据CNV造影特点和CNV与黄斑中心凹的距离分为中心凹下CNV包括经典型7眼,隐匿型26眼,盘状瘢痕化9眼,旁中心凹CNV包括经典型2眼,隐匿型12眼,中心凹外CNV3眼均为隐匿型。结论:FFA可以发现AMD患者的CNV,并能分辨其性质和部位,有助于指导治疗和评价预后。
Objective: To investigate the characteristics and clinical significance of fundus fluorescein angiog-raphy (FFA) in patients with age-related macular degeneration (AMD). Methods: 112 cases of 149 eyes underwent FFA examination with Japanese Nikon NF-505 fundus camera. Results: In 149 eyes, there were 90 eyes (60.4%) of atrophic type and 59 eyes (39.6%) of exudative type. According to the characteristics of CNV and the distance between CNV and the foveal fovea, CNV was divided into classic 7 eyes, Type 26 eyes, 9 disc disciform scars, paravalveolar CNV, including the classic 2 eyes, concealed 12 eyes, fovea CNV3 eyes are occult. Conclusion: FFA can detect CNV in patients with AMD and distinguish its nature and location, which can help guide the treatment and evaluate the prognosis.
