目的：确定 Retinomax 和 IOLMaster 眼部生物测量学在学龄前儿童中的可测试性。设计：对洛杉矶县内城区学龄前儿童进行的基于人群的研究。参与者：2545 名 6 至 72 个月大的西班牙裔和 2178 名非裔美国儿童。方法：通过在先前确定的连续人口普查区域内挨家挨户筛查来确定受试者。儿科眼科医生或验光师对所有受试者进行全面的眼部检查。在睫状肌麻痹后，使用 Retinomax 自动验光仪对所有受试者进行屈光不正和角膜曲率测量。尝试使用 IOLMaster 部分相干干涉仪对 30 至 72 个月大的受试者进行眼轴长度测量。主要结果测量：能够获得高置信度的双眼自验光读数或眼轴长度测量值。结果：总体而言，89% 的儿童可使用 Retinomax 设备进行双眼测试，91% 的儿童可使用 IOLMaster 进行测试。可测试性随着年龄的增长而急剧上升，因此到 36 个月大时，98% 的儿童可以使用 Retinomax 设备进行测试，90% 的儿童可以使用 IOLMaster 进行测试。两种设备的整体可测试性或按年龄分层时，不存在一致的性别或种族相关差异。结论：可以使用 Retinomax 和 IOLMaster 设备对幼儿进行可靠的眼部生物测量测试。这可能会影响学龄前儿童白内障和屈光不正的治疗策略。
Purpose: To determine the testability of Retinomax and IOLMaster ocular biometry in preschool children.Design: Population-based study of inner city preschool children in Los Angeles County.Participants: Two thousand five hundred forty-five Hispanic and 2178 African American children 6 to 72 months old.Methods: Subjects were identified by door-to-door screening within previously identified contiguous census tracts. Pediatric ophthalmologists or optometrists performed comprehensive eye examinations on all subjects. Refractive error and keratometry measurements were attempted on all subjects with the Retinomax autorefractor after cycloplegia. Axial length measurements with the IOLMaster partial coherence interferometer were attempted on those subjects ages 30 to 72 months.Main Outcome Measures: Ability to obtain high confidence autorefraction readings or axial length measurements on both eyes.Results: Overall, 89% were testable in both eyes with the Retinomax device, and 91% of the children were testable with the IOLMaster. Testability rose sharply with age, so that by age 36 months 98% of children were testable with the Retinomax device and 90% were testable with IOLMaster. There were no consistent gender- or ethnicity-related differences in testability overall or when stratified by age for either device.Conclusions: Young children can be reliably tested for ocular biometry with the Retinomax and IOLMaster devices. This may impact strategies for management of cataracts and refractive errors in preschool children.
