Testability by Age and Ethnicity with Retinomax and IOLMaster Devices. $280.83. Tonic accommodation: a review, II. A recent Danish paediatric ophthalmic cohort study on the effects of extreme prematurity in survivors now aged 34 years was conducted with a primary focus on development (retina or brain) when visual ability was subnormal.19 The refractive value was taken from the cycloplegic Retinomax printout after a single application of cyclopentholate 1% eye drops. Acta Ophthalmol Suppl 1976; 128: 3245. Squares, triangles base down, and dots specify the preterm subgroups. A constantly changing color display, both on the outside and inside of the device, also keeps children involved during the process. Non-cycloplegic screening for amblyopia via refractive findings with the Nikon Retinomax hand held autorefractor in 3 year old kindergarten children. Fledelius HC . Comparison of the Retinomax hand-held autorefractor versus - PubMed MeSH In the text, Snellen equivalents are presented as decimal values. Standardized Gold Standard Eye (GSE) examinations were performed by optometrists or ophthalmologists who were experienced working with children.6,30 GSE examinations were conducted in a specially equipped vision van parked at each Head Start Center. Subjects refusing cycloplegia were not included in the analysis. Using a low or missing confidence number as the sole criterion, only 14 of the 234 children aged 4 years (6%) would have been identified as candidates for full paediatric ophthalmic status on the suspicion of reduced visual acuity, and 5 would have been false positives.

Similarly, IOLMaster testability rates rise in children so that by age 36 months nearly all children can be tested (Fig 2). Approximately half of children are testable at 6 months of age.

There has been a recent emphasis on examining preschool children to detect refractive errors and risk factors for amblyopia, as well as for understanding normal development of the eye.1 Concomitantly, automated and portable noncontact technologies for purposes of ocular biometry have been developed.2,3 Such technologies may be intimidating and require patient cooperation. .

ROC analysis of the accuracy of noncycloplegic retinoscopy, Retinomax autorefractor, and Sure Sight vision screener for preschool vision screening. The Retinomax device used by professionals has previously been demonstrated to be 64% sensitive for detecting highly amblyogenic refractive errors at 90% specificity in 36-month-old children.5 Testability in that group was >99%, based on achieving any confidence reading, and 95.4%, based on achieving a confidence reading 8 within 3 attempts in either eye without cycloplegia.6 Cycloplegia increases the accuracy of the Retinomax and other autorefractors when used on children.7,8 By 36 months of age, we were able to achieve similar (98%) testability with the Retinomax with cycloplegia with the stricter confidence reading (8) recommended by the manufacturer (Fig 1).

Cycloplegic or noncycloplegic axis values were not different between any method. At all refractive levels, however, the variation seemed unpredictable, and empirical correction factors based on non-cycloplegic refractometer printouts could not be outlined. For the evaluation of EIM, the one-drop-only regimen provides a conservative estimate. 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.
