Prospective Evaluation of Photoscreeners in the Pseudophakic Eyes of Children

Abstract To compare refractive data of Plusoptix AO9 (Plusoptix, Inc., Atlanta, GA) and Spot (Welch Allyn, Skaneateles Falls, NY) photoscreeners with retinoscopy in pseudophakic eyes of children. In this prospective study, patients underwent testing with the Plusoptix and Spot photoscreeners prior to their examination by a pediatric ophthalmologist masked to the results of both photoscreeners. Data including testability and estimated refractions were entered into a Research Electronic Data Capture database for statistical analysis. For bilateral pseudophakia, one randomly selected eye was included in the analysis. Forty-four eyes were included, with a mean age of 7.4 ± 4.8 years. Refraction was estimated in all eyes using retinoscopy, but a refractive estimate was obtained in only 11.3% (5 of 44) of eyes using the Plusoptix binocularly and 63.6% (28 of 44) of eyes using the Spot. Compared to retinoscopy, the Plusoptix showed a mean difference of -0.80, 0.10, and -0.75 diopters (D) for sphere, cylinder, and spherical equivalent, respectively (P > .05). Comparable values for the Spot were 0.18, -0.26, and 0.05 D, respectively (P > .05). Compared to retinoscopy, the Plusoptix showed a mean absolute difference of 1.30, 0.80, and 1.25 D for sphere, cylinder, and spherical equivalent, respectively (P > .05). Similar values for the Spot were 1.38, 0.88, and 0.97 D, respectively (P > .05). Refraction was estimated in a higher number of pseudophakic eyes of children using the Spot as compared to the Plusoptix. The Spot may be useful to evaluate myopic shift in pseudophakic eyes of children. [J Pediatr Ophthalmol Strabismus. 2016;53(3):146-149.].
