In the first trial, the within-session repeatability of the AA was measured in 79 subjects between 18 and 30 years of age using DR and two subjective procedures, namely the modified push-down MPD and minus lens ML techniques.
In a second trial, the inter-session repeatability of the AA was assessed in 76 subjects by a single evaluator with a time interval of 7 days between the first and second sessions.

It consists of a typical electric retinoscope with a small revolving disk which contains various small figures and letters electrically illuminated by a special device and situated just below the reflecting mirror, and is the object which the patient fixes on when the presbyopic error is estimated.
Dynamic retinoscopy DR is an objective technique for assessing maximum accommodative responsivity.
