Description

<p> The waveform in the resting state of accommodation under fogging was analyzed using an advanced objective accommodometer (ARK-1s, NIDEK) in normal eyes of participants of various ages. The subjects were 219 persons (219 eyes) between 6 years and 47 years old without eye diseases affecting accommodation (81 males, 138 females; mean age, 16.7 ± 9.3 years old). The mean spherical equivalent of the subjects was -3.04 ± 2.31 D. Eyeblink and the rate of poor fixation (deletion rate) were used as indices representing the measurement reliability of models used for measurements in this study, and double the standard deviation of the refractivity (accommodation variation) was used as an index representing the stability of accommodation. The median deletion rate was 13.2%, and there was a tendency for the deletion rate to become higher as the cylindrical power became higher (p<0.005). The median accommodation variation was 0.15 D, and there was a tendency for the accommodation variation to become higher as age is low (p<0.05).</p><p> The ARK-1s was usable for measurement of accommodation even in young patients. It was suggested that the accommodation variation in the resting state of accommodation is affected by age in normal eyes.</p>
