Abstract

Purpose: To collect the normal value data of corneal hysteresis in Thais and study the variation of corneal hysteresis in glaucomatous eyes.

Methods: Retrospective cross-sectional study of corneal hysteresis (CH) in healthy non-glaucomatous and glaucomatous eyes. Demographic data, type and staging of glaucoma, Goldmann applanation tonometry (GAT) and ocular response analyzer parameters; CH, corneal-compensated intraocular pressure (IOPcc) and Goldmann-correlated intraocular pressure (IOPg) were collected.

Results: Data from one eye of 465 normal participants were included for the normal value data of CH. Mean CH, IOPcc and IOPg were 10.18 ± 1.48, 15.01 ± 3.04 and 14.16 ± 3.06 mmHg, respectively. Average age was 57.21 ± 14.4 years. CH at the fifth percentile was 8.0 mmHg. Women had significantly higher CH than men (10.29 ± 1.46 vs 9.90 ± 1.49 mmHg, p=0.009). Moderate negative correlation was found between age and CH, r = -0.338, p<0.001. There were 695 glaucomatous eyes from 429 patients including primary-open angle glaucoma (POAG), primary close-angle glaucoma (PACG), normal tension glaucoma (NTG) and ocular hypertension (OHT). CH in each glaucoma type and severity stage (early, moderate and severe) were as follows: POAG: 8.74 ± 1.52 mmHg (9.22 ± 1.47, 8.74 ± 1.23 and 7.92 ± 1.40 mmHg, p<0.001), PACG: 9.09 ± 1.72 mmHg (9.85 ± 1.45, 9.04 ± 1.68 and 8.45 ± 1.74 mmHg, p= 0.004), NTG: 9.55 ± 1.67 mmHg (9.47 ± 1.38, 9.75 ± 2.42 and 9.77 ± 1.34 mmHg, p 0.525) and OHT: 10.10 ± 1.40 mmHg.

Conclusion: Compared with normal value data of corneal hysteresis, CH in glaucomatous eyes was lower. The more advanced glaucoma stage was associated with lower CH. Arising from normal value data, a low percentile of CH could be applied as the deviation value from normal and this dynamic property of CH could represent a glaucoma predictor in an effort to improve glaucoma care.

泰国人角膜迟滞及青光眼患者角膜迟滞的变化。

目的:收集泰国人角膜迟滞正常值资料，研究青光眼角膜迟滞的变化。方法:对健康非青光眼和青光眼的角膜迟滞(CH)进行回顾性横断面研究。人口统计学资料、青光眼的类型和分期、Goldmann眼压计(GAT)和眼反应分析仪参数;采集CH、角膜代偿性眼压(IOPcc)和goldmann相关眼压(IOPg)。结果:选取465例正常人单眼CH正常值资料，平均CH、IOPcc和IOPg分别为10.18±1.48、15.01±3.04和14.16±3.06 mmHg。平均年龄57.21±14.4岁。第五百分位的CH为8.0 mmHg。女性CH明显高于男性(10.29±1.46 vs 9.90±1.49 mmHg, p=0.009)。年龄与CH呈中度负相关(r = -0.338, p)。结论:青光眼CH较角膜迟滞正常值低。青光眼分期越晚，CH值越低。根据正常值数据，低百分比的CH值可以作为与正常值的偏差值，而CH的这种动态特性可以作为青光眼的预测指标，以改善青光眼的护理。

期刊介绍： Clinical Optometry is an international, peer-reviewed, open access journal focusing on clinical optometry. All aspects of patient care are addressed within the journal as well as the practice of optometry including economic and business analyses. Basic and clinical research papers are published that cover all aspects of optics, refraction and its application to the theory and practice of optometry. Specific topics covered in the journal include: Theoretical and applied optics, Delivery of patient care in optometry practice, Refraction and correction of errors, Screening and preventative aspects of eye disease, Extended clinical roles for optometrists including shared care and provision of medications, Teaching and training optometrists, International aspects of optometry, Business practice, Patient adherence, quality of life, satisfaction, Health economic evaluations.
