Extraocular Muscle Repair and Regeneration

Exrraocular Muscle Regeneration in Freeze-Treated Extraocular Muscle Autograffs

New growth of extraocular muscle has been demonstrated in degenerating peripheral nerve autografts implanted between two extraocular muscles. This suggests that extraocular muscle may be lengthened for therapeutic purposes if a suitable matrix can be found to support this new growth. Investigators of peripheral nerve regeneration have found that the basal lamina of freeze-killed skeletal muscle...

Accessory extraocular muscle.

Although on cover test the child maintained fixation easily with either eye, he preferred to view with the right eye. A marked left convergent strabismus was present, the deviation being greater on accommodation; the cover test also showed alternating hypertropia. When fixing with the right eye the horizontal deviation was approximately 35A with left hypertropia and when fixing with the left ey...

Extraocular muscle and Harderian gland degeneration and regeneration after exposure of rats to continuous fluorescent illumination.

Exposure of adult albino rats to continuous cool-white fluorescent illumination caused extensive destruction to the extraocular skeletal muscles (EOM's) and Harderian glands. After 1 day of exposure, leukocytes and macrophages invaded the damaged area and were found among and within the myofibers. After 48 hr of exposure, myoblasts and short myotubes extending from the damaged fibers indicated ...

Regulation of skeletal muscle size, regeneration and repair.

Ultrastructure of mepivacaine-induced damage and regeneration in rat extraocular muscle.

Adult rats were given a single retrobulbar injection of 50 microliters of 2.0% mepivacaine and the lateral rectus muscles were examined ultrastructurally at intervals from 15 min to 30 days post-injection. There were three purposes of the study: (1) to determine the extent of muscle fiber damage caused by the anesthetic; (2) to document the subsequent course of muscle fiber regeneration; and (3...
