简介：波前像差引导的准分子激光角膜屈光性手术的出现,使个体化切削成为可能,通过矫正人眼生理系统的高阶像差,人们期望获得超常视力及对比敏感度.但由于像差会受到衍射和散射影响,同时还会随时间、泪膜厚度、瞳孔大小以及调节的变化而波动,从而影响得到无像差的视网膜成像.无像差的视网膜成像还要受到视网膜采样以及大脑神经系统识别等因素的影响.因此,个体化切削不一定能产生超常视力.

简介：眩晕是指患者感受周围环境或自身运动时产生的运动幻觉。眩晕症是最常见的临床综合征之一。Neuhauser报道眩晕症的患病率约为4．9％，发病率约为1．4％，而周围性眩晕是眩晕症的重要组成部分，约占眩晕门诊中的20．5％。引起眩晕的疾病种类很多，不同疾病引起眩晕的原因是不一样的。按照病变部位的不同，眩晕可以分为周围性眩晕和中枢性眩晕两大类。

简介：目的探讨一种规范化的的高度近视白内障超声乳化方式,总结手术注意点。方法选取高度近视白内障患者91例（91眼）均予以超声乳化联合人工晶体植入术治疗并总结。结果所有病例的术后裸眼视力均优于术前裸眼视力。术后第1天裸眼视力≥0.2共72眼（79.12%）,≥0.5共37只眼（40.66%）;术后3月裸眼视力≥0.2共85只眼（93.41%）,≥0.5共42只眼（46.15%）。最佳矫正视力≥0.2共89只眼（97.80%）,最佳矫正视力≥0.5共72只眼（79.12%）。术前散光度平均1.10D±0.78D,术后3月散光度平均1.25D±0.72D。术后散光度与术前散光度比较,差异无显著性（t=1.166,P=0.261）。无瞳孔严重变形、视网膜脱离、囊样黄斑水肿、瞳孔夹持、青光眼以及顽固性葡萄膜炎等并发症。结论低能量,高负压,低灌注,连续环形撕囊,双手劈核技术对于高度近视白内障患者更加安全有效。

简介：目的探讨数字化多媒体系统矫治训练对大龄儿童弱视的治疗效果。方法选取2013年1月至2016年1月我院门诊收治的大龄弱视患儿86例（128眼）,作为研究对象。根据患儿治疗方案的差异将其分为观察组与对照组,对照组45例患儿接受常规综合治疗措施,观察组41例患儿接受数字化多媒体系统治疗,比较两组患儿治疗后双眼视功能变化及疗效。结果观察组患儿治疗后总有效率明显高于对照组,并且观察组患者立体视改善率明显高于对照组,P〈0.05,差异具有统计学意义。结论对大龄弱视患儿采取数字化多媒体系统治疗可有效改善患儿弱视症状,提高患儿双眼视功能,缩短患儿视功能障碍治疗时间,具有临床应用及推广价值。

简介：目的分析个性化角膜切口对白内障术后角膜散光及裸眼视力的影响。方法90例（106眼）白内障患者分为2组，试验组选择位于角膜最大屈光度径线上透明角膜切口，对照组选择11：00处的透明角膜切口，行白内障超声乳化人工晶状体植入术。术前及术后1周、1个月、3个月分别检测患者角膜散光及视力情况。结果术后1个月和3个月试验组裸眼视力分别为（4．9±0．15）、（5．0±0．15），显著优于对照组的（4．8±0．18）、（4．8±0．20），差异有统计学意义（P〈0．05）。术后1个月和3个月试验组角膜散光度分别为（0．78±0．39）、（0．79±0．40），明显低于对照组的（1．53±0．32）、（1．52±0．28），差异有统计学意义（P〈0．05）。结论白内障患者术前大多存在〈1．5D的角膜散光。采用个性化角膜切口可降低白内障手术角膜源性散光，术后视力恢复好，是一种简便、可行的手术切口。（中国眼耳鼻喉科杂志，2013，13：168—169，172）

简介：目的：探讨首选个体化巩膜扣带术治疗孔源性视网膜脱离的临床效果。方法：回顾分析92例95眼孔源性视网膜脱离伴增生性玻璃体视网膜病变C1级以下的病例,根据裂孔位置、数目、视网膜脱离的形态等首选放液或者不放液的巩膜扣带术,个别病例辅以玻璃体腔注气术。随访时间7～48（平均10.2）mo。结果：视网膜一次手术复位成功90眼（95%）,视力由术前的4.03±0.42到术后的矫正视力4.58±0.33。结论：首选个体化巩膜扣带术治疗孔源性视网膜脱离能够用最小量的手术、最小的创伤,获得较高的视网膜复位率和较好的视功能。

简介：目的对临床可疑青光眼患者进行长期的偏振激光扫描仪联合个体化角膜补偿技术（scanninglaserpolarimetrywithvariablecornealcompensation，GDxVCC）随访，分析GDxVCC对该类患者的诊断价值。方法选取门诊可疑青光眼的眼底检查视乳头杯／盘比（C／D）≥0．4，或双眼不对称且C／D差值〉10．2，静态视野检查结果正常患者68例，随访前后均用GDxVCC检查（采用相同的角膜补偿值）。如双跟C／D值相同，随机选取1眼，如C／D值不同，则选取C／D值大的1眼，对结果进行t检验统计学分析。结果随访时间6～30个月，平均（12．5±7．0）个月，眼底C／D值为0．57±0．17。随访前后GDxVCC检查：椭圆平均值分别为50．33±7．72和49．66±8．12，上方平均值为58．72±13．56和58．18±12．01，下方平均值为60．71±11．31和59．13±11．95，神经纤维指数为30．85±19．62和33．03±21．22，差异无统计学意义，但从绝对数值上，椭圆平均值、上方平均值和下方平均值变小，神经纤维指数变大。其中7例（10．3％）诊断为青光眼，21例（30．9％）排除青光眼，40例（58．8％）仍需进一步随访。结论对临床怀疑青光眼的患者应长期进行随访，GDxVCC随访对青光眼的诊断有一定的价值。（中国眼耳鼻喉科杂志，2009，9：92—94）
