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.

12 Cases of Retinal detachmant by the scleral buckling procedure

12 cases of retinal detachment treated with scleral buckling Procedure of 4392 visitors the department of ophthalmology. Yonsei University medical school from Feb. 28th 1958 to April 30th 1959. 30 cases of retinal detachment were found 12 cases out of 30 received the scleral buckling procedure, and exhibited the following results. 1) a. Successful, b. Fair 3(25%), c. Failure 2(16.6%). 2) The shorter the duration of retinal detachment existed the better the resutls of the operation was. However in 2 cases of old retinal detachment lasted more than 7 months the results of the operation were also successful. 3) Results of the surgery were more favourable in the cases of having no definite hole. 4) In one case, retinal detachment was recurred a year after the first procedure and a secondary procedure was performed with fair results.
