“…16 17 We suppose that the strabismus after cataract surgery also results from muscle hypertrophy induced by bupivacaine. 18 Fibrosis and Figure 1 The patient immediately after bupivacaine injection (above), and at 33 days after injection (below). Informed patient consent was obtained for publication of this figure. scarring, the current putative causes for such strabismus, have not been documented by biopsy, nor found in animal injection studies.…”

“…A hipótese de que a bupivacaína pudesse contri buir para o tratamento do estrabismo foi aventada depois de casos de estrabismo causados pela sua in jeção acidental dentro do músculo durante bloqueio retrobulbar para cirurgia de catarata. O desvio nesses pacientes, inicialmente, foi atribuído simplesmente à miotoxicidade, porém a observação cuidadosa da evo lução clínica permitiu entender o complexo mecanis mo que envolve tanto o aumento da contratilidade, como da rigidez muscular 15,16 . Com o melhor escla recimento do seu mecanismo de ação, a bupivacaína passou a ser usada para tratamento de estrabismo como alternativa à cirurgia.…”

“…Bupivacaine is an anesthetic drug that has been used in peri bulbar and retrobulbar anesthesia for a long time and presents few complications (6) . Many studies have shown that muscles in which bupivacaine was accidentally injected such as in anesthetic blocks for cataract surgery, presented a change in ocular alignment with sub sequent diplopia (7) . Hypertrophy of such muscles after bupivacaine injection has been described (810) .…”
