Out of Results: 75 participants in each group percentage with grade 0 pain in posterior subtenon's group was 64(83 %) as compared to 6( 8%) in peribulbar group. Among all 20 (27%) participants of peribulbar group and 2 (3%) of posterior subtenon's group had attained complete akinesia. Both the groups had experienced similar amount of lid movements. Occurrence of complications like chemosis and sub conjunctival hemorrhage was noted more in posterior subtenon's group when compared to peribulbar group |
