In order to get accurate three-dimensional data of extraocular muscles that can be used to build an acceptable static display model of the eye, the anatomic structure of the extraocular muscles was analyzed and the rough shape of the muscles had been grasped.

为了获取较为精确的外肌的活体立体数据,以便利用计算机建立人们易于接受的部组织的静态显示模型,本文首先对外肌的解剖结构进行了分析,初步把握了外肌的结构形态。

The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

逆地振型水平半规管良性阵发位置性眩晕的3种耳石可能位置如下:水平半规管前臂的管耳石、管侧的顶帽沉石(canal side cupulo-lithias1s)与囊侧的顶帽沉石,本文报告3例以快速转头治疗逆地振型水平半规管良性阵发位置性眩晕成功的病例,显示快速转头法对囊侧的顶帽沉石具迅速有效的治疗效果,对於逆地振型水平半规管良性阵发位置性眩晕的治疗,作者建议先以快速转头作治疗性诊断,若病人马上复原,诊断为囊侧的顶帽沉石;若振转为向地型,则诊断为水平半规管前臂的管耳石或管侧的顶帽沉石,进一步再以向地型的耳石复位法治疗病人。

AIM:To investigate and analyze the central corneal thickness of hyperopic eyes and assess the safety of LASIK for hyperopia.

目的:应用角膜测厚仪测量和分析远视的中央角膜厚度,探讨LASIK治疗远视的安全性。方法:回顾性统计分析102例204远视的中央角膜厚度,并与激光切削深度做对比。

After birth, eye small, short axial length, so almost all of hyperopia, hyperopic astigmatism or both, as the age increased, the development of eyes have grown up, axial growth, development can become the focus squarely (no hyperopia, myopia, astigmatism).

RESULTS: A total of 45 eyes from 45 patients were treated with the Ahmed glaucoma valve implant and its combination surgery. At a mean follow up of 9.7 months (range3~18months), the mean intraocular pressure was reduced from 36.8±12.3mmHg before the implant surgery to 18.0±4.5mmHg at the last follow up after surgery. The success rate was 87%.The best postoperative corrected visual acuity improved 16 eyes(35%).Transient postoperative hypotony and shallow anterior chamber occurred in 20% of cases. The common postoperative complication in later was the formation of encapsulated bleb(13%).

结果:难治性青光45例(45)实行了Ahmed青光阀植入术或联合晶状体摘除、玻璃体切割、人工晶状体植入术等;术后平均观察(3~18)9.7mo;患者术前的平均压36.8±12.3mmHg,术后平均压18.0±4.5mmHg;手术成功率87%;术后最佳矫正视力提高16(35%),视力无变化21(47%),视力降低8(18%);术后早期最常见的并发症是一过性浅前房及低压,发生率为20%,晚期最常见的并发症是滤过泡包裹,发生率是13%。
