高度近视主要变化在黄斑,但很难发现其血行情形,现以高速摄影进行研究。(本文曾在23届世界眼科学术会上发表)。选600D以上近视共105眼,年龄20—68岁,全矫视力都在0.5以下,以大型眼底镜及萤光素眼底血管造影等方法研究。观察结果: (一)视乳头血行: 1、深层血管,认为是由脉络膜而来,因附近组织退行性变,故能在近视弧斑与乳头缘平行处可清楚看到Zinn-Haller血管环走行,血管向心入乳头深处,血管丰富,并有后睫状血管及脉络膜血管分枝混入乳头中。 The main changes in high myopia in the macula, but it is difficult to find the blood situation, are high-speed photography research. (This article was published in the 23rd World Conference of Ophthalmology). Selected more than 600D myopia, a total of 105 eyes, aged 20-68 years old, the whole correction of visual acuity in 0.5 below, with large fundus fundus fluorescein fundus angiography and other methods. Observations: (A) optic disc blood line: 1, deep blood vessels, that is from the choroid, due to the nearby tissue degeneration, it can be in the myopia arches and nipple edge can be clearly seen parallel to the Zinn-Haller vascular ring walk , Blood vessels into the heart deep into the nipple, rich in blood vessels, and posterior ciliary vessels and choroidal blood vessels mixed into the nipple.
