近视是眼科常见的遗传性眼病,正常群体的发病率可高达30.39%,变性近视(≥6D)占6.89%。近年来近视眼中开角型青光眼的患病率明显升高。二者均具有胶原组织的病理改变,变性近视眼巩膜曲率半径增大、变薄而发生眼球扩大。这种薄而膨胀的巩膜对眼压有一定的影响,因而用Schi(?)tz 眼压计测置眼压时往往造成一种假性低眼压,这对变性近视眼中开角型青光眼的诊断往往造成贻误。笔者为研究变性近视 Myopia is a common hereditary ocular ophthalmopathy, the incidence of normal population can be as high as 30.39%, degeneration of myopia (≥ 6D) accounted for 6.89%. In recent years, the prevalence of open-angle glaucoma in myopia was significantly higher. Both have pathological changes of collagen tissue, degenerative myopia scleral curvature radius increases, thinning and ocular enlargement occurred. This thin and swollen sclera has a certain impact on intraocular pressure, and therefore the use of Schi (?) Tz tonometer intraocular pressure to measure the setting often leads to a pseudo-low intraocular pressure, which degenerative myopia in open-angle glaucoma Diagnosis often results in bungling.
