“…16,26 In children, the reported repeatability differs widely among researchers (±0.23-0.85 mm), 17,18 presumably because the repeatability is dependent on how much cooperation was obtained from the children. Compared with these values, the repeatability of the IOLMaster measurement that we found in children was 5 to19 times more precise.…”

“…Another advantage of this device is its high precision. 15,16 In children, Carkeet et al 17 and Hussin et al 18 reported that test-retest repeatability of this measurement was ±0.047 mm and ±0.04 mm, respectively (Table 1). However, these studies provided no information regarding refractive errors in the subjects, and thus it is still unknown whether the reported repeatability can be expected in children with a wide range of refractive errors.…”

“…The repeatability of ultrasound biometry in children was found acceptable in a previous study. 30 The optometrists performing the above effi cacy measurement and visual acuity testing were masked regarding the treatment that the children received. To detect any adverse effects, careful and comprehensive examination, including slit-lamp and fundus examination, was performed by a single ophthalmologist for all subjects on a trimonthly basis.…”

“…Partial coherence interferometry has not been previously studied in preschoolers, but it has been demonstrated to be more reproducible than A-scan ultrasonography in measuring axial length in school age children. 9,10 Ophthalmologists and optometrists with pediatric subspecialty training performed all of the tests in this study. Testability of preschoolers with these devices using non-professionals in a screening setting may thus be less.…”

Testability of the Retinomax Autorefractor and IOLMaster in Preschool Children

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.Correspondence and reprint requests to Rohit Varma, MD, MPH, Doheny Eye Institute, Department of Ophthalmology, 1450 San Pablo Street, Room 4900, Los Angeles, CA 90033-9224. rvarma@usc.edu. * For members of the Study Group, see "Appendix" (available at http://aaojournal.org).The authors have no proprietary or commercial interest in any materials discussed in the article. . These devices can also be used in the management of amblyogenic cataracts for calculating intraocular lens (IOL) power and postoperative spectacle or contact lens correction. The reliability of these and other biometric technologies has been validated in adults but has not been thoroughly validated in preschool children. The purpose of this study is to determine the testability of these two instruments in a large population-based cohort of preschool Hispanic and African American children. HHS Public Access Materials and MethodsThe Multi-ethnic Pediatric Eye Disease Study (MEPEDS) is a population-based study designed to (1) estimate and compare the prevalence of strabismus, amblyopia, and refractive error in a sample of African American, Asian American, Hispanic/Latino, and non-Hispanic Caucasian 6-to 72-month-olds and (2) evaluate the association of selected demographic, behavioral, biological, and ocular risk factors with these ocular disorders. To date, examination of the African American and Hispanic/Latino populations has been completed. Assessment of the other ethnic groups is being initiated. Thus, we are reporting the results for African American and Hispanic/Latino children only.Subjects are identified by door-to-door screening of families within 35 previously identified contiguous census tracts in Los Angeles County.

Repeatability of IOLMaster Biometry in Children

Abstract: Partial coherence interferometry techniques, such as that used by IOLMaster, should be considered as the standard technique for axial length measurement in children because they are noninvasive, highly precise, and easy to use.
