Primary and secondary overacting inferior oblique muscles: an ultrastructural study.
نویسندگان
چکیده
Biopsy material from primary and secondary overacting inferior oblique muscles were examined by light and electron microscopy. Most muscle fibres were in different stages of atrophy. A high variation of alterations was encountered in all muscles. The most striking abnormalities were huge accumulations of mitochondria and muscle vacuolisation related mainly to the enlargement of the tubules of sarcoplasmic reticulum. The mitochondrial aggregates and vacuolisation occupied more muscle surface in the inferior muscles of primary overaction than those of secondary overaction.

Capillaries of human overacting extraocular muscles.
The capillaries of overacting inferior oblique muscles from children with strabismus and of dog inferior oblique muscles were ultrastructurally described. Biopsy material was used in all instances. The mean diameter of the capillary lumen was 2.03 microns for the human inferior oblique and 2.76 microns for the dog inferior oblique. Quantitative estimates of capillary basement membrane width wer...
متن کاملComparison of inferior oblique muscle weakening by anterior transposition or myectomy: a prospective study of 20 cases.
BACKGROUND/AIMS Among the various weakening techniques of inferior oblique muscle overaction, the most commonly used techniques include myectomy, recession, and anterior transposition. Anterior transposition and myectomy were compared to evaluate the surgical results in inferior oblique overaction. METHODS 20 children with bilateral +3 overacting inferior oblique muscles underwent a prospecti...
متن کاملIncreased frequency of activated satellite cells in overacting inferior oblique muscles from humans.
PURPOSE Strabismus is an oculomotor disorder in which there is a misalignment of the visual axes of the eyes. Inferior oblique muscle (IOM) overaction is a common finding in comitant horizontal strabismus, but its origin is unclear. Recent studies have demonstrated that myogenic satellite cells (SCs) are still activated in adult extraocular muscles, with continuous myonuclear addition in normal...
متن کاملIncomitant 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 double-bellied inferior oblique muscle: clinical correlates.
PURPOSE We previously reported an 8% incidence of double-bellied inferior oblique (IO) muscles at the surgical capture site (10-12 mm from insertion) in cadaveric specimens. This companion study sought to determine how often this anomaly is encountered at surgery for clinically overacting IO muscles and whether clinical findings or surgical outcomes in cases with double-bellied muscles differ f...
