吲哚青绿血管造影联合广角接触镜观察涡状静脉

目的 应用吲哚青绿血管造影（ICGA）联合Staurenghi 230广角接触镜观察和分析人眼涡状静脉的形态及其分布特征。 方法 对28例32只眼进行广角接触镜联合ICGA检查。受检者中女性16例19只眼，男性12例13只眼；年龄28～84岁，平均年龄71岁。根据受检眼不同屈光度分为高度近视组和非高度近视组，前者15只眼，屈光度数≥－6.0 D；后者17只眼，屈光度数＜-6.0 D或正视。 结果 本组受检者中，共发现166支涡状静脉，其中，漩涡状118支，占71.1%；粗条纹状34支，占20.5%；不规则状14支，占8.4%。右眼发现涡状静脉71支，平均每一只眼有涡状静脉507支；左眼发现涡状静脉95支，平均每一只眼有涡状静脉5.28支。颞下、鼻下、颞上及鼻上象限发现的涡状静脉数分别为47、42、39、38支，平均每个象限1.34支，以颞下象限最多，每一只眼平均为1.在赤道部附近，距视盘约4~6 个视盘直径（DD），占964%；6支涡状静脉出巩膜点距离视盘较近约3～4 DD,占3.6%。123支涡状静脉可见明显壶腹，占74.1%，壶腹方向以平行或垂直于眼底水平线者多见。高度近视组和非高度近视组在涡状静脉数目、形态上差异无统计学意义。 结论 人眼涡状静脉形态呈漩涡状、粗条纹状、不规则状；高度近视眼与非高度近视眼涡状静脉分布特征基本一致，均以颞下象限最多，出巩膜点多在距视盘约4~6 DD处，多数可见明显壶腹。广角接触镜下ICGA检查视角广，能在一个视野内同时观察到几乎全部的涡状静脉。

An observation of vortex veins by indocyanine green angiography and wide-field lens

Objective To observe and analyze the configuration and distribution of vortex veins by indocyanine green angiography (ICGA) combining with wide field contact lens system. Methods A total of 28 patients (32 eyes), including 16 females (19 eyes) and 12 males (13 eyes) with the age of 28-84 (average 71), were examined by ICGA combing with wide field contact lens. The patients were divided into high myopia group (15 eyes with diopter ≥-6.0 D) and non high myopia group (17 eyes with diopter <-6.0 D or normal sight). Results A total of 166 vortex veins were detected, including 118 circinate veins (71.1%), 34 thick-stripe-like veins (20.5%), and 14 irregular vein (8.4%). There are 71 vortex veins in the right eyes with average 5.07 vortex veins in each eye; and 95 veins in the left eyes with average 5.28 vortex veins in each eye. The number of vortex veins at in the inferior temporal, inferior-nasal, over-temporal and over-nasal retina was 47, 42, 39, and 38, respectively, with average 1.34 vortex veins in each quadrant (the inferior temporal was the most: average 1.53). A total of 160 vortex veins came out from the scleral around the equator area 4 6 disc diameter (DD) away from the optic disc (964%); the other 6 vortex veins came out at the point 3-4 DD away from the optic disc (3.6%). A total of 123 (74.1%) vortex veins had ampullae with different directions. Horizontal and vertical ampullae were most common. There was no difference in numbers and configuration of vortex veins beween the two groups. Conclusion The vortex veins has circinate, thick-stripe-like, and irregular configurations; the distribution of vortex veins in eyes with high myopia or non high myopia is almost accordant. ICGA combining with the wide-field contact lens examination can observe all of the vortex veins within a single visual field.
