The oculocardiac reflex was quantitatively studied in 15 patients with strabismus. The reflex was observed in all patients when the medial rectus and inferior oblique muscles were stretched; the medial rectus muscle had a lower threshold than the inferior oblique. Bradycardia was evoked in 7 of the 15 patients when the lateral rectus was tractioned with tensions of 50 g and 600 g. The oculocard...

BACKGROUND Lack of standardised orbital MR protocols leads to a situation, when each institution/centre may arbitrarily choose sequence parameters. Therefore, the results obtained and published by the authors may not be compared freely, and what is most important may not be considered fully reliable. Signal intensity (IS) and T2 time (T2) are important parameters in estimation of inflammatory p...

We described the clinical, surgical details and results (motor and sensory) of the retrieving procedure of traumatically avulsed muscles in three patients with no previous history of strabismus or diplopia seen in the Department of Ophthalmology, State University of Campinas, Brazil. The slipped muscle portion was reinserted at the original insertion and under the remaining stump, which was sut...

PURPOSE To investigate the distribution of the intermediate filament (IF) proteins desmin, vimentin, and nestin in human extraocular muscles (EOMs). METHODS Healthy adult EOM samples were serially sectioned (5 and 1 μm) and processed for immunohistochemistry, with specific antibodies (Abs) against desmin, vimentin, and nestin and different myosin heavy chains (MyHCs), including the newly char...
