Objective To observe and analyze the configuration and distribution of vortex veins by indocyanine green angiography (ICGA) combining with widefield 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 widefield contact lens. The patients were divided into high myopia group (15 eyes with diopter ge;-6.0 D) and non high myopia group (17 eyes with diopter lt;-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 inferiortemporal was the most: average 1.53). A total of 160 vortex veins came out from the scleral around the equator area 46 disc diameter (DD) away from the optic disc (964%); 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.
