INTRODUCTION AND PURPOSE This study examines the sensory and motor results in adult patients with large-angle exotropia treated with nonadjustable bilateral recess-resect procedures. METHODS A consecutive series of adult patients undergoing four-muscle surgery for exotropia ≥ 50(Δ) with no previous surgery were identified by retrospective medical record review. All patients had nonadjustable ...

AIM To investigate the postoperative eye alignment and binocular visual function after early surgery for infantile esotropia. METHODS Both the postoperative eye position and stereopsis were reviewed using the Titmus stereo test in nine patients who received uniocular medial rectus recession and lateral rectus resection under general anaesthesia before 8 months of age and were followed up for ...

A rare case of granular cell myoblastoma is reported in a 37-year-old man where the tumour was situated within the medial rectus muscle. Histological, cytochemical and ultrastructural examination showed it to have features typical of granular cell myoblastoma. It also reacted with chorioembryonic antigen antisera, a sign of primitive cell origin. The findings add further weight to the idea of t...

BACKGROUND To compare the rate of exodrift after a second surgery for recurrent exotropia, in patients grouped to fast versus slow exodrift after their first surgery. To determine whether there is a correlation with surgical outcome, and to evaluate the factors associated with fast exodrift. METHODS Patients with recurrent intermittent exotropia, who underwent contralateral lateral rectus rec...

The present study was conducted to observe the effect of graded mechanical stimuli on occurrence of oculocardiac reflex (OCR). The experiments were carried out in twenty albino rabbits of either sex weighing between 1-2 kg. Changes in heart rate and/or cardiac rhythm (oculocardiac reflex) were studied by applying traction with progressively increasing weights to medial rectus muscle. Mean thres...

Under general anaesthesia the eye position of esotropia generally moved divergently. When retrobulbar anaesthesia was added bilaterally, the eye position moved further in the same direction. In the electromyogram under general anaesthesia the 4 horizontal recti were silent in controls. In many cases of esotropia, however, both medial recti showed a considerable amount of discharge under general...

It seems clear, both from pathological material in humans t°,15 and experiments in monkeysS, 34, that the median longitudinal fasciculus (MLF) carries a stimulus to the medial rectus subnucleus of the oculomotor complex to effect the adductive portion of lateral gaze. The importance of this pathway was emphasized by Shanzer et al. 34, who showed that section of the MLF of the monkey blocked add...
