Objective To evaluate the change of blood sugar in diabetic patients after vitrectomy and analyze the relative reasons. Methods Nineteen diabetes II patients (20 eyes) who underwent vitrectomies received the tests of blood sugar preoperatively, and 1～2 hours, 1, 3, and 5 days postoperatively. Analysis of variance, apaired Student rsquo;s t-test, and correlation analysis were used to analyze the change of postoperative blood sugar and correlation between postoperative blood sugar change and its relative factors. Results Postoperative blood sugar increased significantly compared with the preoperative one (P lt;0.05),reached the peak 1～2 hours postoperatively, and reached almost the preoperative level 5 days postoperatively (P gt;0.05). There was a positive correlation between blood sugar increase and operation time, preoperative blood sugar level, and diabetic duration (P lt;0.05). Postoperative blood sugar was relative to potentiated anesthesia. Conclusion There is a regularity that blood sugar increases just postoperatively and reaches the preoperative level 5 days postoperatively. The relative factors to blood sugar change include preoperative blood sugar level, diabetic duration, operation time, and potentiated anesthesia. (Chin J Ocul Fundus Dis,2000,16:157-159)
