Abstract

To predict the mydriatic status of the cataract patients preoperatively, we performed maximal mydriasis test with stepwise instillations of 1% tropicamide and 2.5% phenylephrine or 10% phenylephrine to the out-patients who was scheduled to have cataract operation. Among 210 eyes of 113 patients, the pupillary size of 167 eyes was dilated to 8mm or more and the other 43 eyes were insufficiently dilated to less than 8mm diameter. In the insufficiently dilated group, we have observed the presumable causes of insufficient mydriasis as follows: posterior synechiae, diabetic autonomic pupillopathy, age-related miosis and unknown. By this test, we could predict the mydriatic status of the cataract patient preoperatively and could prepare the appropriate operative method and equipment effectively.
