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:通过临床的系统观察研究泪点发生炎症的原因及泪点炎发展转归的临床规律,以及设计实施相应的手术治疗等,显示把泪点炎作为独立疾病列出的必要性。方法:用裂隙灯观察泪点和眼表,并泪道冲洗、探通检查;用微距照相记录泪点典型病变,其中有24眼泪点切除组织进行病理学检查。结果:泪点炎病临床特征:几乎所有泪点炎患者都合并急、慢性结膜炎;多数为泪点单独发炎,少数与后续泪道炎性阻塞疾病合并存在。急性泪点炎少见,溢热泪,泪点局部红肿、痒痛,泪点壁贴合关闭泪点口,以抗炎药物治疗为主。慢性泪点炎多见,溢冷泪,主要有泪点壁软缩,泪点乳头平坦,泪点口向心性缩小;增殖膜覆盖泪点口;泪点壁肿胀、增生贴合关闭泪点口;增生的睑结膜包裹稀薄的积脓包埋泪点口,形成白色隆起的泪点外观四种类型。以手术治疗为主,效果良好。结论:本研究结果显示,泪点炎病多发而常见,有独特的发展转归临床规律,和单独的手术治疗方法,把泪点炎作为独立疾病单独列出,以减少泪道病诊治的疏漏和错误等非常必要。
简介:结膜松弛症是年龄相关性老年性常见眼病,随着人口老龄化加快,患者日趋增多。下睑缘张力高、睑板腺功能障碍及结膜淋巴流动阻塞可能是结膜松弛症诱发因子之一。自身免疫性甲状腺疾病患者结膜松弛症发病率高。结膜松弛症患者球结膜杯状细胞减少,并有形态及超微结构异常表现。结膜松弛症泪液分泌减少,泪膜稳定性下降,泪液中黏蛋白减少,出现调节凋亡相关蛋白质和防御素。细胞凋亡和炎症可能是结膜松弛症发病的原因。结膜松弛症发病机制认为是泪液中IL-1β,IL-6,肿瘤坏死因子-α等炎性因子增加,使结膜成纤维细胞中MMP-1,3,9过度表达,使得MMPs与TIMPs之间失去平衡,可能使胶原纤维融解,弹力纤维变性减少,导致球结膜基质和Tenon囊的过度降解,引起眼表泪液异常的病理循环,而发生结膜松弛症。纤维蛋白胶应用于结膜松弛症手术中,电凝治疗结膜松弛症及开展上方结膜松弛症手术治疗。
简介:目的:探讨角膜地形图引导的个性化切削术(topographyguidedcustomizedablation,TOGCA)治疗高度散光的临床疗效。方法:选择2006-05/09在我院屈光中心接受TOGCA的散光≥-2.00D的复性近视散光患者53例87眼。术前、术后行角膜地形图检查,分析手术前后角膜散光度及散光轴的变化。结果:术后裸眼视力优于术前最佳矫正视力,差异有显著的统计学意义(P〈0.05),无1例最佳矫正视力下降。术前眼总体散光-2.44±0.47D,角膜散光-2.56±0.58D,均为顺规散光。术后眼残留散光-0.17±0.34D,除1例(2眼)发展了-1.00D的散光,其余患眼均在±0.50D以内,角膜散光-0.10--2.60D,平均-0.98±0.46D,部分角膜散光欠矫与非角膜散光因素正相关。散光轴位变化较术前改变约14.13±19.18度。结论:TOGCA治疗高度散光具有良好的可预测性、安全性和有效性。术后散光较术前明显减小,手术前后角膜散光轴均保持了良好的一致性。
