A comparison of the effects of cycloplegics on accommodation ability for distance vision and on the apparent near point.
The relationship between distance accommodation ability and the near point of accommodation (NPA) was investigated following the instillation of a cycloplegic. A high correlation between the two parameters was found (p less than 0.001). It is suggested that the effect of a cycloplegic may be more directly assessed using distance accommodation measurement and, in the case of young children, with more ease. A limit of 0.75 D of distance accommodation ability is suggested as a threshold for satisfactory cycloplegia.
