The Result of Canaliculodacryocystorhinostomy with Double Probing in Common Canalicular Obstruction

PURPOSE: To evaluate the results of endoscopic canaliculodacryocystorhinostomy with double probing to resolve common canalicular obstruction. METHODS: A total of 47 patients (56 eyes) with common canalicular obstruction underwent endoscopic canaliculodacryocystorhinostomy. The double probing method was applied to 28 eyes; the remaining 28 eyes were in the control group. The success rate, degree of symptom improvement, and complication rate of the two groups were compared and analyzed. RESULTS: The postoperative success rate was 96% in the group that underwent surgery with the double probing method and 86% in the control group (P=0.160). The rate of symptom improvement without tearing was 86% in the double probing method group and 61% in the control group (P=0.038). Postoperative complication rates such as granuloma formation were 7% and 29% in the study and control groups, respectively (P=0.036). CONCLUSIONS: Endoscopic canaliculodacryocystorhinostomy with double probing to resolve common canalicular obstruction is proven to be effective in enhancing patient satisfaction and lowering complication rates, with no additional costs and risks.

A Case of Macular Edema after Rosiglitazone Use

PURPOSE: To report a case of macular edema after the use of the oral hypoglycemic agent rosiglitazone. METHODS: A 43-year-old man, who had diabetic mellitus and was on oral rosiglitazone therapy, complained of a visual disturbance in his left eye. After fundus examination and optical coherence tomography, macular edema was observed, therefore rosiglitazone therapy was discontinued. RESULTS: After 2 weeks, his visual acuity improved, and macular edema decreased in the left eye on optical coherence tomography. CONCLUSIONS: Rosiglitazone use should be considered as one of the potential causes of macular edema.
