We thank Dr Kannan for highlighting the risk of globe perforation due to two-injection technique for peribulbar block in our report.[1,2] Although medial canthus block has lower incidence of globe perforation, we suggest that sub-tenon block is an another safer alternative for primary ophthalmic block.[3] Sub-tenon block indications are same as of peribulbar block. Sub-tenon block can be administered in patients with long axial length where peribulbar block is avoided due to increased chances of globe rupture.[3] Volume of local anaesthetic varies from 3 to 10 ml depending on the type of surgeries. It results in lesser increase in intraocular pressure than peribulbar block.
