摘要
①目的 测量中老年白内障病人的角膜厚度、前房深度、晶体厚度及角膜曲率 ,为角膜屈光手术提供确切的解剖基础。②方法 采用进口A型超声、角膜测厚及角膜曲率仪对中老年白内障病人 10 99只眼的角膜厚度、前房深度、晶体厚度及角膜曲率进行检测并统计分析。③结果 角膜中央厚度为 (5 0 5 .0 0± 4 2 .38) μm ,下方为(6 4 8.4 3± 76 .80 ) μm ,鼻侧为 (6 2 7.4 4± 99.0 5 ) μm。前房中央深度为 (2 .913± 0 .4 6 5 )mm。晶体厚度为 (4 .5 5 2±0 .90 1)mm。角膜曲率 :水平径线 (HK) (94 4 .0 93± 1.74 7)D ,垂直径线 (VK) (4 4 .134± 1.6 13)D。角膜中央厚度男女之间有差别 (t=2 .793,P <0 .0 1)。前房深度与角膜中央厚度呈正相关 (r =0 .138,P <0 .0 5 ) ,与晶体厚度呈负相关 (r =- 0 .2 90 ,P <0 .0 0 1) ,角膜曲率HK与VK呈正相关关系 (r =0 .6 85 ,P <0 .0 0 1)。④结论 该测量可为眼前节疾病的诊断及角膜屈光、青光眼、白内障等手术提供解剖参考。
Objective\ To measure corneal thickness (CT), anterior chamber depth (ACD), lens thickness (LT), and corneal curvature (CC) i n middle aged and elderly patients with cataract, to provide anatomic data for operation of refraction. Methods\ A measurement was done in 1 099 eyes by A mode ultras ound. All the parameters of the items mentioned above were analyzed statistical ly.\ Results\ Central thickness of the cornea was (505.00±42.38)μm, i nferior (648.43±76.80)μm, nasal ( 627.44± 99.05)μm, ACD (2.913±0.465)mm ,LT (4.552±0.901)mm, respectively. Vertical CC and horizontal CC were ( 44.09 3± 1.747 )D and (44.134±1.613)D, respectively. There was a difference b etween male and female in terms of central thickness of the cornea(CT1)( t=2.7 93,P <0.01). There was positive correlation between ACD and CT1 ( r=0.138, P <0.05),vertical corneal curvature (VK) and horizontal corneal curvature (HK) ( r=0.685,P <0.001). There was a negative correlation between ACD and LT ( r=-0.290, P <0.001). \ Conclusion\ This study provides anatomic data for diagnosis of a nterior segment diseases of eye and surgery in corneal refraction, glaucoma and cataract .
