ABSTRACT Five subjects showing slow accommodative responses were given orthoptic treatment. Speed of accommodative response improved after 3 to 6 weeks. No regressions were evident 18 weeks after the cessation of training. Slow accommodative responses were found in subjects with normal phorias and fusion limits. The technique of dynamic photorefraction is introduced for the clinical measurement of accommodative time characteristics.
Bobier et al. (Mon,) studied this question.
