An evaluation of the monocular estimate method of dynamic retinoscopy.
Monocular Estimate Method (MEM) dynamic retinoscopy is an objective clinical method for determining the accommodative response to a fixed accommodative stimulus. Although MEM has been used in many clinical investigations, it has never been compared with the measurement of accommodative response by the haploscope. This report compares the accommodative responses obtained by MEM and by a haploscopic instrument, the phoroaccommodometer. Linear regression analysis indicates that MEM consistently provides a close approximation to the phoroaccommodometer finding (r = 0.975, p less than 0.001). A conversion table has been generated so MEM findings may be adjusted to correspond with the phoroaccommodometer at higher stimulus values.
