The advent of a new technique that is considered much safer than previously established one leads to its rapid adoption. This usually leads to the identification of previously unreported complications of the new technique, and a re-assessment of its position in clinical care, which is precisely the state of play with the sub-Tenon's block. The sub-Tenon's block was introduced into the clinical practice in early 1990. A systematic recent search of subject headings such as complications of sub-Tenon's block, subtenon, orbital block, orbital block complications, and orbital anaesthesia was performed in Medline, EMBASE, and Cochrane database. Indeed there are complications of sub-Tenon's block published as case reports and the exact incidence of these complications is not known. Management and preventive measures of these complications are described. Although the sub-Tenon's block appears to be relatively safer than needle-based blocks but a proper prospective, randomized, double-blind controlled trial is essential for scientific proof that sub-Tenon's block is better than needlebased blocks.

“…However, complications that have been reported are more or less similar to those associated with other methods of local infiltration anesthesia used for cataract surgery, namely globe perforation, 5 severe orbital hemorrhage, 6,7 transient occlusion of the central retinal artery, 8 damage to extraocular muscles leading to diplopia, 9 and orbital cellulitis. [10][11][12] All previously reported cases of orbital cellulitis were treated with parenteral antibiotics in conjunction with systemic steroids. Our patients were treated with oral steroids alone or in conjunction with oral antibiotics, and they showed similar resolution without complications.…”

Two cases of orbital swelling after sub-Tenon's anesthesia are reported. The first patient presented 3 days postoperatively with proptosis and conjunctival chemosis. Computed tomography showed nonspecific inflammation of the orbital soft tissue. Signs and symptoms resolved after systemic steroids. The second patient presented with similar signs and mild pain on the fourth postoperative day. Computed tomography showed a similar diffuse orbital inflammation. The patient was treated with oral steroids and antibiotics, and all inflammation subsided within 4 weeks. Both patients had uneventful cataract surgery, were apyrexial, and were generally well. A few possible mechanisms for these episodes are infection, reaction to povidone-iodine or sub-Tenon's anesthetic, or trauma due to the sub-Tenon's cannula.
