Static retinoscopy results with and without a fogging lens over the non-tested eye.

This study addressed the question: "Should both eyes be fogged during static retinoscopy?" Static retinoscopy measures were taken on young patients. (N = 50; mean age = 9 years, 4 months). Outcomes revealed no differences except with hyperopic patients, where the lack of a fogging lens over the partner eye resulted in a significant underestimate (p less than .001) of the refractive status. This argues against the use of a lens bar for retinoscopy especially in vision screening programs involving young children.

The validity of the Frisby stereotest as a measure of precise stereoacuity.

This paper reports the outcomes of a study that compared the performance of 20 binocular adults on the Frisby stereotest and the TNO. (All subjects were prescreened with the Random-dot E stereotest administered at 1.5 m.) Significant intercorrelations were found (Pearson r = .73; two-tailed p less than .001), adding support to the clinical usefulness of the Frisby stereotest. Other characteristics of the two tests--including communication requirements and administration time--are compared.

A new version of the TVAS: a validation report.

The purpose of this study was to investigate the validity of a revised version of the Test of Visual Analysis Skills (TVAS). Data are presented from testing 198 subjects in two elementary schools with two versions of the TVAS and a second perceptual skills test (VMI). Within-age-group, between-school statistical comparisons strongly support the validity of the revised TVAS.

A procedure for measuring the near-point fusional vergence reserves of young children.

This paper describes a modification of the standard method for measuring near-point fusional vergence reserves that reduces dependency upon patient's verbal responses by employing a fixation target that can be perceived accurately only when viewed binocularly. As such, the procedure is particularly useful with young children whose subjective responses often tend to be unreliable. Data from 34 preschool children are reported.

Screening for perceptual skills dysfunction: an up-date.

The paper argues that the primary-care practitioner has an obligation to screen the visual and auditory perceptual skills of all his/her elementary school-aged patients. Two easy-to-administer tests are described, along with guidelines for interpreting and making decisions on the basis of test outcomes.

The effectiveness of the random dot E stereotest as a preschool vision screening instrument.

Sixty nursery-school children (ages 39--76 months) were screened with a modified-clinical method (visual acuity, retinoscopy, cover test, NPC) and with a relatively new vectographic test for stereopsis--the Random Dot E. Screening outcomes indicate that the RDE was as effective in identifying children for referral as was the modified clinical battery. Implications are discussed.
