The Studies on the Residual Accommodation of Koreans II. The Residual Accommodation under 0.5% Scopolamine and l% Cyclogyl Cycloplegia

ABSTRACT

This study was conducted to determine how much of a residual accommodation remained under 0.5% scopolamine and 1% cyclogyl in young Koreans ranged from 6 years to 20 years. The amount of the residual accommodation was measured by the blur point method, and the following results were obtained. 1) The average residual accommodation for 150 eyes was 0.99 D under 0.5% scopolamine and for 96 eyes was 1.53 D under 1% cyclogyl. 2) In comparing the cycloplegic agents, 0.5% scopolamine was almost parallel with 1% atropine (0.96D) and 1% cyclogyl was almost parallel with 5% homatropine (1.42 D). 3) The residual accommodation under 0.5% scopolamine and 1% cyclogyl showed a gradual decrease with increasing age as Erst reported for 1% atropine and 5% homatropine. 4) In comparing with foreign countries, the residual accommodation in Koreans was at a similar level with white people.
