Prospective Comparison of the Pediatric Ophthalmologist Refraction and Vision Screener in Pseudophakic Eyes of Children
Narrative Responses:
Purpose
To evaluate the performance of the photoscreener plusoptiX A09 (P) and Spot (S) in measuring refraction by comparing them with retinoscopy (R) in pseudophakic eyes of children.
Methods
Prospective cross-sectional evaluation to compare data from R performed by pediatric ophthalmologis with refraction obtained using P and S performed by a lay screener. For bilateral pseudophakia, randomly selected one eye was included in analysis. After informed consent, patients underwent testing with the P and S prior to their examination by a pediatric ophthalmologist masked to the results. Data including estimated refractions were entered into a REDCap database for statistical analysis. Statastical analysis was performed using Chi-square test and pair-T rest.
Results
Forty-two eyes were included, with a mean age of 8.1 ±5.6 years. Refraction was estimated in all eyes using retinoscopy, however, in 11.9 % (5/42) in P group and in 61.9% (26/42) of S group (P <0.001). Compared to R, the P showed a mean difference of -0.8, 0.1, and -0.75 for sphere, cylinder and spherical equivalent respectively (P >0.05). Similar values for S were 0.01, 0.16 and 0.09 D respectively (P >0.05).
Conclusion
Refraction was estimated in higher number of pseudophakic eyes of children using Spot as compared to Plusoptix. When refraction was obtained, it was comparable to pediatric ophthalmologist measured reading.
