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

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.

The Studies on the Residual Accommodation of Koreans I. The Residual Accommodation under 1% Atropine and 5% Homatropine Cycloplegia

This study was conducted to determine how much of a residua1 accommodation remained one hour after three instillations of atropine or homatropine in 384 eyes of younger Koreans. The amount of residual accommodation was measured by the blur point method, and the following results were obtained. 1) The average amount of the residual accommodation was 0.96 D under l% atropine and 1.42 D under 5% homatropine. 2) In comparing the two cycloplegic agents, 1% atropine was found to be more effective than 5% homatropine. 3) Residual accommodation under l% atropine and 5% homatropine showed gradually decrease in older patients. 4) No sex difference was found.

A Recent Survey of Pterygium Operation

The authors operated 46 cases of pterygia by the modifed Walter's procedure, which was combined with excision, baring the sclera at the limbus, cautery of the limbus, limbal groove, and transplantation. The following results were obtained. 1) 39 cases out of 46 cases were successfully treated, however 7 cases recurred. The rate of recurrence was 15.2 percent 4 cases of pterygia which recurred received a free graft from the upper bulbar conjunctiva, using a modified Walter's procedure. The results of reoperation were satisfactory in 3 cases. 2) The recurrence rate was greater in cases of the highly vascular, thick, inflamed, and rapid growing type. 3) To date, no evidence of astigmatism and other complications due to the utilization of these modifications have been noted in our cases. 4) The authors believe that good technique, treatment of chronic conjunctival inflammation, and improvement of life environment are the most important factors in the prevention of recurrence. However, the last factor is a very difficult problem in Korea. 5) Using the best developments from several standard surgical procedure for the treatment of pterygia the authors was able to lower their recurrence rate.
