About

Pediatric eye patients receive infrared photoscreener screening and skiascopy as a part of routine examination to compare ability to detect amblyopia risk factors.

Full description

Patients: Pediatric eye and adult strabismus patients undergoing routine examinations in a private ophthalmology practice.

Interventions: Infrared photoscreener / remote autorefractor such as 2 Winner (2WIN) ("Adaptica" - Padova, Italy) without and with infrared corneal reflex occluder. Child-friendly skiascopy before and after cycloplegic refraction.

Outcome: Amblyopia Risk Factors from comprehensive eye exam including refraction and strabismus.

Risk factors defined by American Association for Pediatric Ophthalmology and Strabismus (AAPOS) 2003 and 2013 guidelines.

**Please note that 2 Winner has nothing to do with actual device, but was required by the Clinical Trials Web entry.**

Enrollment: 471 patients

Sex: All

Ages: 1 week to 90 years old

Photoscreener (2WIN)

Description:

Accommodation, refraction and ocular alignment are estimated by infrared photoscreener using the photoscreener device. Photoscreener screening makes use of light crescent quantification from off-axis flash-to-lens in a camera.

Treatment:

Device: 2WIN photoscreener

school bus skiascopy

Description:

Refractive error estimated by child-friendly skiascopy rack holding lenses from +1.00 D to +10.00 D and -5.00 D. Skiascopy is a common, old-fashioned form of retinoscopy.
