• Detection of Amblyogenic Refractive Error Using the Spot Vision Screener in Children OPTOMETRY AND VISION SCIENCE Gaiser, H., Moore, B., Srinivasan, G., Solaka, N., He, R. 2020; 97 (5): 324-331

  Abstract

  Vision screenings are conducted to detect significant refractive errors, amblyopia, and ocular diseases. Vision screening devices are desired to have high testability, sensitivity, and specificity. Spot has demonstrated high testability, but previous reports suggest that the Spot has low sensitivity for detecting amblyogenic hyperopia and moderate sensitivity for amblyogenic astigmatism.This study assessed the concurrent validity of detecting amblyogenic refractive errors by the Spot (v.1.1.50; Welch Allyn Inc., Skaneateles Falls, NY) compared with cycloplegic retinoscopy.A total of 475 subjects (24 to 96 months) were screened by Spot and then received a masked comprehensive examination. Sensitivity and specificity, Bland-Altman plot, receiver operating characteristic area under the curve, and paired t test were evaluated by comparing the results of the Spot (v1.1.50) using the manufacturer referral criteria with the results of the comprehensive examination using the 2013 American Association for Pediatric Ophthalmology and Strabismus criteria.The Spot (v.1.1.50) referred 107 subjects (22.53%) for the following: 18.73% (89/475) astigmatism, 4.63% (22/475) myopia, 0.42% (2/475) hyperopia, and 2.11% (10/475) anisometropia. The sensitivity and specificity of the Spot vision screener for detecting amblyogenic risk factors were 86.08% (95% confidence interval [CI], 76.45 to 92.84%) and 90.15% (95% CI, 86.78 to 92.90%). Areas under the curve were 0.906 (95% CI, 0.836 to 0.976) for hyperopia, 0.887 (95% CI, 0.803 to 0.972) for spherical equivalent, and 0.914 (95% CI, 0.866 to 0.962) for astigmatism. A modified hyperopia criteria cutoff of greater than +1.06 D improved the sensitivity from 25 to 80% with 90% specificity. The current cutoff criterion, greater than -1.75 D, for astigmatism seemed optimal.This study shows that the Spot vision screener accurately detects low spherical refractive errors and astigmatism. Lowering the hyperopia cutoff criteria from the current Spot screener referral criteria improves the sensitivity with desired (high) specificity.

• Validity of the Spot Vision Screener in detecting vision disorders in children 6 months to 36 months of age JOURNAL OF AAPOS Srinivasan, G., Russo, D., Taylor, C., Guarino, A., Tattersall, P., Moore, B. 2019; 23 (5): 278-279

  Abstract

  To evaluate the Spot Vision Screener in detecting targeted vision disorders compared to cycloplegic retinoscopy in children <3 years of age.Children, ages 6 months to 36 months underwent vision screening using the Spot Vision Screener. Results were compared to results of comprehensive eye examinations. Validity of the Spot was evaluated by calculating the area under the curve (AUC); the receiver operating characteristics (ROC) were used to determine optimal sensitivity and specificity for detection of targeted vision disorders.A total of 249 children were included. The AUC for detecting targeted vision disorders as defined by the study specific criteria using the Spot was 0.790. Compared to cycloplegic retinoscopy, the Spot underestimated hyperopia by 1.02 D (95% CI, 0.86-1.17 D). For hyperopia ≥4.5 D spherical equivalent (n = 10), the mean difference between the Spot and cycloplegic retinoscopy was 3.46 D (95% CI, 1.95-4.98 D). In contrast, the Spot overestimated astigmatism compared to cycloplegic retinoscopy (-1.00 D vs -0.48 D; P < 0.001) by -0.52 D (95% CI, 0.43-0.62 D).The Spot Vision Screener showed good overall validity in detecting targeted vision disorders. It was within 0.5 D and 1 D of cycloplegic retinoscopy with regard to low hyperopia and astigmatism. Higher hyperopic spherical equivalent refractive errors showed larger differences in mean values between the Spot and cycloplegic retinoscopy.
