Physiological and morphological studies on microcirculation of the eye during accommodation

1. 本文利用腐蚀铸型技术和扫描电镜对食蟹猴睫状体血管和房水流出通道的三维结构进行了研究。(1)纤毛体的动脉供应有纤毛后长动脉和纤毛前长动脉两条通路，但没有旋涡系统，没有静脉引流系统。施勒姆氏管的集热器通道与纤毛循环不相通。(2)自行开发的前房灌注铸造材料在主路和巩膜路填充铸造材料。在巩膜流出时，石膏经小梁网、睫状肌间隙、睫状肌束中的小孔隙及睫状肌上间隙到达脉络膜上间隙。(3)注入阿托品（调节性松弛）或伊洛卡品（调节性痉挛）后，纤毛肌束毛细孔变窄。通过红外验光仪发现了人眼调节的微波动与心脏的脉动之间的关系。用同样的方法测量近视眼的调节。结果表明，眼镜矫正近视者的调节反应小于远视矫正者。

1. We examined the three-dimentional structure of the ciliary vessels and of the outflow routes for aqueous humor in cynomolgus monkeys with the corrosion cast technique and scanning electron microscopy.(1) Arterial supply of the ciliary body had two pathways which were the long posterior and the anterior ciliary arteries, but no venous drainage system was seen without the vortex system. The collector channeles of Schlemm's canal had no communication with the ciliary circulation.(2) The casting material infused into the anterior chamber, the method of which was developed by ourselves, was filled in the main and the uveoscleral routes.In the uveoscleral outflow, the cast reached to suprachoroidal space passing through the trabecular meshwork, the ciliary muscle space, small pores in the ciliary muscle bundles and the supraciliary space.(3) The pores in the ciliary muscle bundles became narrowing after instillation of atropine (accommodation relaxation) or ilocarpine (accommodation spasm).2. Relationship between the microfluctuation of accommodation in the human eyeby an infrared optometer and the pulsatiion of heart was found. Using the samemethod, accommodation of the myopia was measured. As the results, the accommodative responses of the corrected myopia by spectacles were smaller than those ofemmetropia.
