Background: Bupivacaine injected into animal muscles induces a cycle of myotoxicity, degeneration, regeneration and hypertrophy of muscle fibres, without adverse effects on other tissues. This induced hypertrophy can be harnessed to treat strabismus. Methods: Bupivacaine, 4.5 ml of a 0.75% solution, was injected into the right lateral rectus (RLR) muscle of a patient who had diplopia and who showed 14-prism-dioptres oesotropia. Results: RLR paresis persisted for 7 days. Then, the RLR regained…

There was an increase of muscle thickness in both botulinum toxin A and bupivacaine injected muscles after 30 days of injection when measured by ultrasonography, and this change was more pronounced on lateral rectus muscles after bupvacaine injection.

Although BUP is promising non-surgical strabismus management, however, it has its own limitations, the need for direct infusion of a relatively large volume of BUP may be one of its major drawbacks that limits its usage in an office method.

Bupivacaine injection in the antagonist of a recessed extraocular muscle (EOM) appears to add an effect to the standard dose-response of a muscle recession, and for patients with esotropia, a single MR recession combined with bupvacaine in the LR can produce a successful motor alignment.

The symptoms of two patients improved and an increase of muscle cross-sectional area was observed, however, it is necessary to be prudent when employing intramuscular bupivacaine in oculomotor paresis treatment until there are more and larger studies.

Bupivacaine injection increased the EOM tension in rabbits to some extent and NO augmented the effect of bupivacaines, and the enlargement of the muscle fibers after bupavicaine injection was shown histopathopathically.

The rightward shift in the length-tension curve of EDL muscles 60 days after bupivacaine injection is likely to contribute to the mechanism for their previously observed protection from contraction-induced injury.

Changes recognised when regeneration was essentially 'complete' are reminiscent of changes that occur in muscles following compensatory hypertrophy produced by synergist ablation, and suggest that the EDL muscle is being made to do more active work and is being influenced by passive forces imposed on it.

Both active and passive stretch of the rectus muscles produced by strabismus surgery dramatically upregulated the processes of satellite cell activation, integration of new myonuclei into existing myofibers, and concomitant upregulation of immature myosin heavy chain isoforms.

It is concluded that increased intracellular levels of Ca++ ions may play a part in the pathogenesis of muscle injury induced by bupivacaine and that their source may be the sarcoplasmic reticulum.

Since the sequence of fiber breakdown induced by BPVC administration was similar to that of progressive muscular dystrophy, this chemical will be one of the most useful tools for studying the pathophysiology of fiber necrosis and regeneration in diseased muscle.
