近视似乎是一种扩张性青光眼(expanding glaucoma),其原因是轻度房角异常、玻璃体及巩膜内压力增加。单纯近视是自身应力损害青年扩张性青光眼(salf-inflicted stress juvenile expanding glaucoma);恶性近视是活动性青年扩张性青光眼;先天性近视是非活动性青年扩张性青光眼。玻璃体内及巩膜内压增高:由于睫状肌附着在巩膜突及锯齿缘部脉络膜,当调节时括约肌、锯齿缘、玻璃体前周边部、晶体小带纤维及晶体前囊均向前移。使得括约肌部虹膜紧贴晶体而致玻璃体及小带纤维在晶体-睫状体间隙密集得足以使房水滞留,同时脉络膜被牵紧。这样,玻璃体内压力上升,但前房及脉络膜上腔压却下降。睫状肌不接到高级中枢远处注视的随意命令则玻 Myopia appears to be an expanding glaucoma due to an abnormally mild angle and increased pressure in the vitreous and the sclera. Simple myopia is its own stress-damaged young glaucoma (salf-inflicted stress juvenile); malignant myopia is active youth expansion glaucoma; congenital myopia is inactive youth expansion glaucoma. Vitreous and scleral pressure increased: due to the ciliary muscle attached to the sclera and jagged choroid margins, when the regulation of the sphincter, serrated edge, the anterior vitreous periphery, the crystalline ribbon fibers and the anterior lens capsule are moving forward. Making the sphincter iridology close to the crystal and vitreous and small ribbon fibers in the crystal - ciliary body dense enough to make aqueous humor retention, while the choroid was held tight. In this way, intravitreal pressure increases, but the anterior chamber and suprachoroidal pressure drop. Ciliary muscle does not receive high-level center of the distant gaze of random order is glassy
