The aim of this study is to evaluate primitively whether the extent and component ofastigmatism influence the regression in degree of spherical (DS) and the best corrected visual acuity (BCVA) of children with hyperopia of +5.00 diopters (D) or greater.Children were screened from outpatient refraction database in the Wenling No.1 Peoples Hospital in Zhejiang province and in Eye & ENT Hospital of Fudan University between June 2005 and December 2015.Eligible eyes were divided into three groups according to the extent of the astigmatism: group of astigmatism ≤-2 D of cylinder,group without astigmatism or with astigmatism >-0.5 D of cylinder, and the group with astigmatism >-0.75 D and ≤-1.75D of cylinder.For the component of astigmatism, eyes with astigmatism as ≤-0.75 D of cylinder were divided into 3 groups: with the rule (WTR), against the rule (ATR) and the group with the oblique.Differences in the changes of BCVA and Refractive error(RE)during follow-up terms were compared within and among groups.Differences in the mean DS or BCVA were not statistically significant between-group according to the extent of the astigmatism at the last visit (P=0.2396 and P=0.2131, respectively).As for the component of astigmatism, the group with the oblique astigmatism had more severe hyperopia than the group of WTR (P<0.0001) and mean BCVA in the group of ATR were inferiorto that of the other two groups (P<0.0001) at the first visit.However, the among-group changes were not significant at the end of the observation (P>0.1).The regression of DS and improvement of the BCVA in children with hyperopia of +5.00D or greater may be irrespective of the component and the extent of astigmatism.

眼压升高被认为是青光眼的定义,青光眼的危险随着眼压水平的增高而增加.目前有观点认为眼压水平被确定为青光眼的主要危险因素,但不是唯一.眼压不是青光眼危险的全部,有些病人即使眼压下降了但疾病仍然在变化.应全面考虑眼压的各个方面和其他影响视神经乳头的因素。（青光眼是多因素疾病，IOP只是其中之一，一些病人存在非IOP依赖的因素，眼压不是青光眼危险的唯一因素，还存在着其他例如OPP和CSF-P等因素；尤其
原发性青光眼，特别是原发性开角型青光眼是持续终身的疾病，因而持续终身的随诊有可能减少失明和严重视功能损伤的危险，分析了眼压与青光眼的关系，总结了其诊断过程中是否需要监测眼压波动以及如何监测，每次随诊均应关注并认真评价患者的用药依从性。另外，突发单眼高眼压除了可能的原发性青光眼或青一睫综合征外，也见于新生血管性青光眼、角膜内皮炎(角膜中央后弹力层皱褶、灰色细小KP)及小梁网炎等。

高度近视眼由于长眼轴的原因,其白内障特点与常规白内障有所不同,甚至有的手术具有巨大挑战.治疗此类白内障必须知晓其临床特点和可能发生的并发症介绍了其解剖特征，采用白内障超声乳化手术进行治疗，高度近视患者IOL常会出现低或负度数，建议仍应囊袋内植入IOL，能降低发生PCO风险，不需要行YAG激光囊膜切开，从而降低RD风险，降低发生RD的风险，IOL是很好的生物屏障，能防止玻璃体前移。唯一为高度近视白内
