Study Groups

Spot photoscreener
Automated vision screener: Spot Vision Screener VS 100, Welch-Allyn. This photoscreener is a portable device, using an infrared light. It is built to detect amblyogenic risk factors. First of all, the spot photoscreener produces a sounds which attracts the child's attention and helps him shift his gaze towards the device, held at 1 meter in front him. The spot then evaluates for refractive errors, anisocoria, strabismus, ptosis and media opacity. The ophthalmologic evaluation consists of the measure of the visual acuity, ocular alignment, anterior and posterior segment. The patient will be cyclopleged with cycloplegic drops and will be refracted to obtain a cyclopleged refraction. This will determine his refractive error.
