Incomitant strabismus: does extraocular muscle form denote function?
The paradigm that an "underacting" extraocular muscle is always atrophic or hypoplastic and that an overacting extraocular muscle should always be enlarged leads to inconsistencies with clinical observations. These include findings of "overacting" inferior oblique muscles, superior rectus muscle overaction or contracture syndrome, and normal extraocular muscle diameters in patients with apparen...
متن کاملThe Suh Muscle Hook: A New Muscle Hook for Tight Extraocular Muscles during Strabismus Surgery
Purpose: To introduce an advanced muscle hook to decrease risks and create more feasible extraocular muscle surgeries for physicians. Case Report: Tight extraocular muscles during strabismus surgery could be extremely challenging even in experienced hands due to restricted globe rotation, limited view, and lack of muscle elasticity. Although a variety of surgical instruments have been introduce...
متن کاملExtraocular muscle dynamics in diplopia from enophthalmos.
The mechanism of diplopia from enophthalmos is not well understood. We describe a 55-year-old man who underwent a left transorbital craniotomy for clipping of a basilar aneurysm. The lateral orbital wall was not reconstructed properly, resulting in 8 mm of left enophthalmos. Months after surgery the patient developed diplopia with ocular excursions, although he remained orthotropic in primary g...
متن کاملExtraocular muscle force generation after ricin-mAb35 injection: implications for strabismus treatment.
PURPOSE Ricin-mAb35 is an immunotoxin targeted against skeletal muscle. Previously, we have shown that injection of ricin-mAb35 into rabbit extraocular muscle results in long-term muscle loss, and we have proposed this as a potential treatment for strabismus. In this study, we assessed the effects of ricin-mAb35 injection on extraocular muscle force generation. METHODS Ricin-mAb35, 0.2 microg...
متن کاملIncreasing muscle strength as a treatment for strabismus: sustained release of insulin-like growth factor-1 in rabbit extraocular muscle.
PURPOSE Currently, no drug treatment is available for strengthening underacting extraocular muscles (EOM) in strabismus. We showed previously that single injections of insulin-like growth factor (IGF-1) result in significant but short-term increases in muscle force generation. This study examined the effects of sustained release of IGF-1 on force generation in rabbit superior rectus muscles. ...
