Comparison of SureSight autorefractor and plusoptiX A09 photoscreener for vision screening in rural Honduras.

Purpose: To evaluate the SureSight autorefractor and compare it to the plusoptiX A09 photoscreener in the detection of amblyopia risk factors in a cohort of Honduran children examined during medical mission work and to assess the utility of both devices in the rural setting.

Methods: The medical records of patients who had undergone SureSight autorefractor screening, plusoptiX photoscreening, and a gold standard pediatric ophthalmology examination, including cycloplegic refraction, during a recent medical mission trip to Honduras were retrospectively reviewed.

Results: A total of 216 children were examined. Of these, 9 (4%) were found to have amblyopia risk factors based on the current referral criteria of the American Association for Pediatric Ophthalmology and Strabismus on ophthalmological examination. The plusoptiX was found to have 89% sensitivity and 80% specificity; the SureSight, using manufacturer's referral criteria, was found to have sensitivity of 89% and specificity of 71%.

Conclusions: Both devices were found to be reliable vision screening devices when used on the general population of remote villages in Honduras, although the specificity of the plusoptiX A09 was higher.
