OBJECTIVE To describe a reversible neurological condition resembling a crossed midbrain syndrome resulting from high frequency stimulation (HFS) in the midbrain. METHODS Postoperative evaluation of quadripolar electrodes implanted in the area of the subthalamic nucleus of 25 patients with Parkinson's disease (PD) successfully treated by HFS. RESULTS Four of the 25 patients experienced rever...

A 53-year-old woman complaining of vertical diplopia, presented with a localized swelling in the right lower lid. Magnetic resonance imaging studies demonstrated a relatively well-defined mass in the inferior rectus with similar signal characteristics to the muscle. Excisional biopsy of the mass revealed granular cell tumor composed of S-100 positive cells with acidophilic granular cytoplasm an...

OBJECTIVE The effect of radiotherapy on moderate and severe Thyroid associated ophthalmopathy (TAO) was evaluated by various objective and quantitative indexes including T2 signal intensity ratios of orbital MRI inferior rectus and ipsilateral temporal muscle (T2SIR), extraocular muscles (EOM) volume, and the degree of exophthalmos using clinical research with prospective, randomized, double bl...

The diagnosis of Graves' orbitopathy is usually straightforward. However, orbital diseases that mimick some clinical signs of Graves' orbitopathy may cause diagnostic confusion, particularly when associated to some form of thyroid dysfunction. This report describes the rare occurrence of localized inferior rectus muscle amyloidosis in a patient with autoimmune hypothyroidism, who was misdiagnos...

PURPOSE To evaluate the effects of bilateral inferior oblique transposition (BIOT) on horizontal deviation from primary position among patients with bilateral dissociated vertical deviation (DVD) associated with inferior oblique overaction (IOOA) in infantile strabismus. METHODS Retrospective chart review was conducted among 19 patients with infantile strabismus. All patients had DVD and IOOA...

We treated a selected group of patients with superior-half bullous retinal detachments by preoperative bed rest and immobilisation of the affected eye using a temporary inferior rectus suture taped to the brow. Sufficient flattening of the retina was achieved in each case to permit successful simple extrascleral detachment surgery.

Twelve consecutive cases are reviewed of unilateral hypotropia due to various causes. In most of them the presenting complaint was of ipsilateral blepharoptosis. Some patients had undergone previous ineffective surgery. The surgical techniques employed and the results obtained are discussed, with emphasis on the necessity to test for inferior rectus restriction. Some interesting sensory results...

BACKGROUND We studied the incidence and clinical characteristics of persistent diplopia related to anaesthesia for cataract surgery in a general hospital. METHODS This was a retrospective review of anaesthesia for 3587 cataract surgeries. Of all the cases of diplopia referred to the ocular motility clinic after cataract surgery, those involving anaesthesia-related diplopia lasting longer than...

PURPOSE In a previous study, the authors found that recession of an extraocular muscle resulted in atrophy of both the recessed muscle and its antagonist. To determine if atrophy, caused by weakening of an extraocular muscle, results in changes in developed tension in the antagonist, the authors studied force development of the cat lateral rectus muscle after adductor weakening. METHODS Tenot...
