[The relation between resting point of accommodation and refractive state].
The refractive state in darkness (dark focus of accommodation) was measured in 224 eyes of 112 young subjects with a Canon Autoref R1 and differences of the refractive state in dark and bright rooms were studied. The dark focus of accommodation was also compared with refractive error after instillation of 1% cyclopentlate hydrochloride. Accommodation was almost entirely responsible for myopic shift in the dark focus of accommodation. Myopic shift was larger in hyperopic eyes than in myopic eyes, but hyperopic shift occurred in markedly hyperopic eyes. In emmetropic and myopic eyes, the degree of hyperopic shift by cycloplegia had no parallel relationship with that of myopic shift in the dark focus of accommodation.
