Abstract Purpose:To evaluate the state of refraction screening of congenital nasolacrimal duct obstruction(CNLDO)using SpotTM Vision Screener(Welch Allen).

Method:From April 2017 to March 2018, 138 children with epiphora who first visited Ophthalmology Department of Kanagawa Children's Medical Center were included. We examined SpotTM Vision Screener for 94 cases of children with clinical diagnosis of unilateral CNLDO from 6 to 30 months of age(48 boy, average age 13.7±6.2 months). In cases with spherical, cylindrical, anisometropia exceeded±1.0D, were re-examined under condition with accommodative paralysis using instillation of cyclopentolate. Amblyopia risk factor was based on the American Association for Pediatric Ophthalmology and Strabismus(AAPOS)2013 criteria(12-30 months:hyperopia>4.5D, myopia>−3.5D, astigmatism>2.0D, anisometropia>2.5D).

Results:Sixty-three cases(67%)could be examined by SpotTM Vision Screener at the first visit. The average equivalent spherical value in non-mydriatic condition was+0.9±0.64D for non-affected eyes and 0.15±0.69D for affected eyes(n. s.). Six cases(10%)were examined by SpotTM Vision Screener under accommodative paralysis. Mean equivalent spherical values were+2.81±1.05D for non-affected eyes, +3.85±1.81D for affected eyes, and significant differences were seen(p=0.04, paired t-test). Eight cases(13%)(hyperopia;3 cases, astigmatism;5 cases)corresponded to amblyopia risk criteria about refractive error.

Conclusion:Thirteen percent of infants' with unilateral CNLDO corresponded to amblyopia risk factor about refractive error. Refractive screening using SpotTM Vision Screener was useful for infantile CNLDO.
