Hemorrhages were graded as follows: 1) spot ecchymosis of eyelid and or subconjunctival hemorrhage; 2) eyelid ecchymosis involving half of the lid surface area; 3) eyelid ecchymosis all around the eye,no increase in intraocular pressure; 4) retrobulbar hemorrhage with increased intraocular pressure. ·RESULTS: In group A,grade 1 was observed in 13 patients(1.74%) and grade 2 in 2 patients(0.26%). In group B,grade 1 was observed in 12 patients(1.6%) and grade 2 was absent. No 3 or 4 hemorrhage grade was encountered in both groups. There was not significant difference in grade 1 hemorrhage between both groups(P =0.21). ·CONCLUSION: Oral anticoagulants were not associated with a significant increase in potentially sight-threatening local anesthetic complications.展开更多
