超声生物显微镜和光学测量仪对闭角型青光眼前房深度及角膜厚度测量的比较

目的探讨超声生物显微镜(Ultrasoundbiomicroscope,UBM)与光学测量仪测量闭角型青光眼前房深度值及角膜厚度值是否存在差异.方法应用德国产Zeiss-Humphrey840UBM、瑞士产Haag-Streit前房深度计及角膜厚度计测量闭角型青光眼17例(32只眼)的前房深度和角膜厚度并进行统计分析.结果17例(32只眼)UBM测量的平均前房深度为(1.939±0.199)mm,前房深度计测量的结果为(1.882±0.254)mm,两者有显著性差异(P＜0.05);UBM测量的平均角膜厚度为(0.579±0.077)mm,角膜厚度计测量的结果为(0.581±0.060)mm,两者之间无显著性差异(P＞0.05).结论UBM测量的前房深度值大于前房深度计测量值,而UBM与角膜厚度计测量的角膜厚度值相似.UBM可以精确地测量前房深度与角膜厚度.

双眼自发性晶状体悬韧带松弛致继发闭角型青光眼一例

双眼自发晶状体悬韧带松弛,导致前房波动,进行性近视加重,继发闭角型青光眼的病例在临床比较少见。本病例报道了1例25岁女性双眼自发晶状体悬韧带松弛不伴有晶状体脱位及形态异常,出现双眼前房波动,近视加重,最终继发双眼闭角型青光眼。经过局部抗炎、散瞳处理和"PHACO IOL(Phacoemulsification intraocular lens)植入 前段玻璃体切除术"将IOL置于睫状沟后,患者眼压得到控制、视力基本矫正至正常。眼科学报2007;23:243-246.     

泪膜改变对Goldmann眼压测量值的影响

目的:探讨泪膜改变对Goldmann压平眼压计测量值的影响.方法:将68例(136只眼)受检者随机分为2组,每组34例.随机选择一只眼作为实验眼.另一只眼作为对照眼.A组的实验眼采用右旋糖苷70滴眼液滴眼,B组的实验眼采用粘弹剂Viscoat滴眼.采用Goldmann眼压计测量2次眼压,比较滴眼前、后测量值的差异.结果:A组对照眼第1、2次的眼压测量值分别为(14.44±2.68)mmHg(1 mmHg=0.133 KPa)、(14.47±2.69)mmHg,两次眼压测量值的差异无统计学意义(t=-0.329,P=0.744).实验眼滴右旋糖苷70滴眼液前、后的眼压测量值分别为(14.41±2.63)mmHg、(12.94±2.59)mmHg.两次眼压测量值的差异有统计学意义(t=13.949,P=0.000).B组对照眼第1、2次的眼压测量值分别为(14.29±2.96)mmHg、(14.35±3.12)mmHg,两次眼压测量值的差异无统计学意义(t=-0.466,P=0.644).实验眼滴Viscoat前、后的眼压测量值分别为(14.53±3.13)mmHg、(11.18±3.07)mmHg,两次眼压测量值的差异有统计学意义(t=22.126,P=0.000).两组的实验眼滴眼后的眼压均呈一致性的下降.结论:泪膜的改变可以使Goldmann压平眼压计的测量值产生偏差.     

努力提高光相干断层扫描检查结果的认知水平提升检查的临床应用价值

原发性先天性青光眼患者术后生活质量的评价

Objective To evaluate the 23-item scale of Quality of Life (QOL) for patients with primary congenital glaucoma (PCG). Methods It was a cross-sectional study. The QOL scale specific for patients with PCG was firstly evaluated on 51 patients with PCG following antiglaucomat surgery at last follow-up visit (7.80 years±2.93 years with a median at 7 years) and 50 participants with normal visual acuity (VA) as control. All participants were aged 5-20 years old. The QOL of PCG was evaluated with type of disease, severity, surgical outcome, postoperative VA, age, gender and personality by using single-factor correlation analysis and multiple-factor stepwise regression analysis. Results The PCG-QOL scale achieved good reliability, validity and responsibility for PCG and 23-item were all qualified for QOL evaluation of PCG. The total scores of QOL in patients with PCG were significantly lower than those of normal individuals (PCG 60.22±10.02,normal individuals 71.41±10.11;t=5.682, P=0.000). Single-factor correlation analysis showed that the total scores of QOL were associated significantly with the severity of glaucoma (F=24.026, P=0.000), surgical outcome (t=2.638, P=0.009) and postoperative VA (F=11.248, P=0.000) ; The visual function scores were associated significantly with the severity (F=12.677, P=0. 000) and postoperative VA (F=10.369, P=0.000) ; The self-care ability scores were associated significantly with the severity (F=11.064, P=0.000) and surgical outcome (t=2.297, P=0.042) ; The social and mental scores were all correlated significantly with the severity (F=6.869, P=0.020; F=5.721, P=0.019) and personality (t=4.352, P=0.009 ; t=2.297, P=0.042). Multiple-factor stepwise regression analysis showed that there were significant correlations between total scores and the severity (β=-6.985, P=0.001 ), postoperative VA (β=-4.978, P=0.003 ) and personality (β=-5.201, P=0.020). Conclusions The PCG-QOL scale could be used for evaluating the QOL of PCG patients aged 5-20 years. The main factors that influence on the QOL of patients with PCG are severity of the disease, postoperative VA and personality. Preventing progression of glaucoma, improving VA and giving right psychological guidance may improve the QOL of patients with PCG.
