Development and Preliminary Validation of a Virtual Reality Approach for Measurement of Torsional Strabismus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDouble Maddox rod (DMR), the gold-standard method for in-office measurement of cyclodeviation, requires an examiner and specialized equipment. The objective of this study was to develop a virtual reality (VR) technique for measurement of cyclodeviation and validate this against the DMR.
methodsA VR-DMR was implemented using a smartphone and commercially available VR viewer. The app displayed a line to each eye and accepted touch inputs from the user to rotate the lines into perceived alignment. VR-DMR cyclodeviation measurements were compared with traditional DMR (T-DMR) cyclodeviation measurements in adults with and without strabismus and children without strabismus.
resultsThirty-one subjects were studied (age 5-88 years, 20 with strabismus). VR-DMR had similar test-retest reliability as T-DMR. VR-DMR was highly correlated with T-DMR (r2 = 0.94, linear regression slope 1.12) with a slight positive bias (linear regression y intercept 1°). VR-DMR was preferred by 54% of subjects with 29% having no preference.
conclusionsA VR method of ocular cyclodeviation measurement using sensory techniques was implemented using commercially available hardware. VR measurements compared favorably with gold-standard DMR measurements, and user feedback was positive. The VR methodology has application for in office and home use by nonexperts for purposes of strabismus monitoring.
