purpose: to evaluate demographics and therapeutic outcomes of patients with third nerve palsy who had been treated between 1999 to 2009 at labbafinejad medical center. methods: in this retrospective study, we evaluated 52 patients with third nerve palsy who had been referred to labbafinejad medical center over a ten-year period. results: in this retrospective study, subjects who had been treate...

PURPOSE To report various clinical presentations and treatment outcomes in a series of patients with extraocular muscle cysticercosis. METHODS This retrospective study reviewed the charts of 43 patients diagnosed with extraocular muscle cysticercosis with computed tomography and orbital B-scan ultrasonography between January 1991 and December 2002. Clinical presentation, results of investigat...

It is difficult to identify the exact cause of ocular motility disturbances in orbital wall fracture patients. By performing CT and ocular motility tests before and after surgery, this study analyzes the functions of the extraocular muscles and determines correlations between the results. Between February 2001 and January 2003, 45 eyes of 45 patients with orbital wall fractures, whose medical r...

D,uke-Elder and Duke-Elder first re ported on the action of choline and nicotine on the mammalian extraocular muscle; this was followed by a study by Brown and Harvey on the cat extrinsic eye muscle. Since then very little investigation has been reported on mammalian extraocular muscle, except by Breinin. Recently, more detailed investigation of cat extraocular muscle has been reported followin...

The purpose of this study is to determine the effect of the extraocular muscles on the response of the eye under static and dynamic loading conditions. Two different types of tests have been performed. First, static displacement tests were conducted utilizing computed tomography to visualize the displacement of the eye within the orbit. Six eyes were tested in situ in matched pairs, one eye wit...

Strabismus may result from abnormal innervation, structure, or function of the extraocular muscles. Abnormalities of the orbital bones or masses within the orbit may also cause strabismus due to indirect effects on the extraocular muscles. This paper reviews some disorders of the orbit that are associated with strabismus, including craniofacial malformations, orbital masses, trauma, and anomalo...

The potential role of sensory feedback from human extraocular muscles has been subjected to considerable speculation in the ophthalmic literature. Extraocular muscles pull against a fairly even load and do not initiate a stretch reflex, even when the eyes are directed toward the boundaries of their respective field of action. These unique working conditions and physiological properties have led...

Extraocular muscles differ from most other skeletal muscles in terms of constituent fiber types and innervation pattern. The rules that govern fiber responses to various experimental interventions for most skeletal muscles, therefore, may not strictly apply to the extraocular muscles. In this study, denervation of the extraocular muscles of Cynomolgous monkeys, Macaca fascicularis, was accompli...

AIM To describe the risk of developing cytomegalovirus (CMV) retinitis after a first episode of extraocular CMV disease in AIDS patients. METHODS A review of the clinical records of 20 AIDS patients, without CMV retinitis, with histologically confirmed extraocular CMV disease, was performed. The main outcome measures were occurrence of CMV retinitis, time to development of CMV retinitis, rela...
