Innervated Myotendinous Cylinders Alterations in Human Extraocular Muscles in Patients With Strabismus
PURPOSE To analyze innervated myotendinous cylinders (IMCs) in the extraocular muscles (EOMs) of normal subjects and strabismic patients. METHODS The rectus muscles of 37 subjects were analyzed. Distal myotendinous specimens were obtained from 3 normal subjects, 20 patients with acquired strabismus, 11 with infantile strabismus, and from 3 with congenital nystagmus, and were studied by using ...
متن کاملAbnormal expression of seven myogenesis-related genes in extraocular muscles of patients with concomitant strabismus.
Hyperplasia or hypoplasia of muscles gradually leads to strabismus. Myogenesis-related genes are involved in extraocular muscle development, including myogenic differentiation 1 (MYOD1), myogenin (MYOG), retinoblastoma 1 (RB1), cyclin-dependent kinase inhibitor 1A (P21), cyclin‑dependent kinase inhibitor 1C (P57), insulin-like growth factor 1 (IGF1) and muscle creatine kinase (MCK). This study ...
متن کاملNeurophysiology of extraocular muscles.
E. lye movements may be divided grossly into "tonic" and "phasic" movements. Are both of these principal types produced by the same motor nerves and muscle fibers, or are separate systems present that are functionally suited to each of the types of movements? Morphological and physiological studies demonstrate that at least two and possibly three neuromuscular systems are present in eye muscles...
متن کاملLong-term effects of ricin-mAb 35 on extraocular muscles of rabbits: potential treatment for strabismus.
PURPOSE The immunotoxin, ricin-mAb 35, composed of ricin conjugated to a monoclonal antibody against the nicotinic acetylcholine receptor of skeletal muscle, has been proposed as a potential new agent for treatment of focal muscle dystonias. It has been demonstrated that direct injection of ricin-mAb 35 into rabbit extraocular muscle (EOM) results in significant muscle loss within 1 week. In th...
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...
