Although metastatic tumors of the pituitary gland and the sellar region are not common, they may radiographically mimic a pituitary tumor. Because the metastasis frequently involves the posterior lobe and because lateral extension to the cavernous sinus is common, patients may present with ptosis, diplopia, or diabetes insipidus. Decrease in anterior pituitary function is less common. Metastatic tumors contain abundant vascular networks, as evidenced by frequent blush on cerebral angiography and increased bleeding at operation. We report the case of a 57-year-old woman who presented with rapid onset of bilateral ptosis and ophthalmoplegia and was found to have a metastatic carcinoma within the pituitary gland.

Thirty-eight patients with computed tomography (CT)-proven orbital fractures and diplopia were studied prospectively to determine the efficacy of steroids in the medical management of orbital fractures. The protocol is based on double-blind assignments to steroid (ST) and non-steroid (NT) treatment groups. Outcome analysis was based on sorting fractures into three CT classes: I-without soft tissue prolapse (n = 15); II-with soft tissue prolapse (n = 14); and III-CT evidence of inferior rectus entrapment (n = 9). Results included resolution of diplopia without surgery in both ST and NT groups in CT classes I and II. Median time course of resolution was compressed to less than 5 days in the ST treatment group, however, versus 13 days in the nontreatment group. All fractures in class III had residual diplopia with five of nine patients having surgical results that were enhanced in the ST treatment group. In addition, enophthalmos was unmasked in the ST treatment group within 1 week of treatment versus 5 months without treatment. A protocol for medical management and surgical decision-making in blowout fracture is presented.

The response of eye movements to edrophonium is easily missed by clinical observation alone. Binocular horizontal ten degree saccades were recorded by infrared oculography, whilst the vision of one eye was occluded, before and after fatigue repeated intravenous injection of dilute edrophonium, and fatigue induced during anticholinesterase inhibition by intravenous edrophonium, in 26 patients with diplopia or ptosis of uncertain aetiology. The most reliable criterion of a positive response was an increase in the amplitude of the saccades of the fixating eye by 10% or more after each of several injections of dilute edrophonium. The response was positive in 13 patients and was difficult to observe clinically when the responses of the saccades of the eyes moving conjugately were unequal and when the patient presented with ptosis and no diplopia. Edrophonium infrared oculography proved to be a sensitive test for weakness due to the neuromuscular junction defect of myasthenia gravis affecting extraocular muscles.

Between July 1984 and March 1985, 51 injections of type A botulinum toxin were given to 39 patients aged 11 to 81 years with various types of strabismus, including paralytic strabismus, sensory exotropia, consecutive and residual postsurgical deviations and partially accommodative esotropia. All deviations were documented by orthoptic assessment and photography. After treatment the patients were followed for up to 3 years. The beneficial effects of a single injection were modest, and a second injection was often necessary to achieve satisfactory ocular alignment. Thirteen of the 26 patients (50%) with nonparalytic strabismus and 10 of the 13 patients (77%) with paralytic strabismus had a good outcome (final deviation 12 prism dioptres or less). Adverse side effects included transient ptosis and diplopia and inadvertent vertical deviation. Twenty-one consecutive cases of nonparalytic horizontal strabismus treated with adjustable sutures were also reviewed. The results in these patients were more predictable and longer lasting than those in the patients who received botulinum toxin.

The patient was a 52-year-old woman who was initially admitted to our hospital with a recent history of diplopia, ptosis and visual impairment on the right, adding to 6 years history of the right orbital pain and temporal headache. She had gradually developed pain and fatigue of the right knee since childhood and had been suffered from multiple subcutaneous tumor in the both hands and the right foot from youth onward. On neurological examination, she has had right exphthalmos and 3rd and 6th cranial nerve palsies on the right. Skull X-ray and CT scan showed parasellar calcified mass on the right. In chromosome examination, the inversion of the No. 1 chromosome was disclosed by the Q- and C-band dyeing of her leucocytes and skin culture. Cavernous hemangioma of her skin lesion and enchondroma of the skeletal lesion were diagnosed by X-ray examination and histological specimen, indicating so-called Maffucci's syndrome. One year and a half later, she was readmitted to our institution, because of progressive visual loss on the right and left hemiparesis. Malignant change of the parasellar lesion was suspected by the clinical course and neuroradiological findings and was confirmed histologically by the second peration. During postoperative course, intratumoral hemorrhage had occurred twice and the patient died, and postmortem examination confirmed her clinical affair. This is the case which was clarified malignant transformation of enchondroma in the parasellar region, and is the first case verified the chromosome abnormalities in Maffucci's syndrome.

Eight consecutive patients with acquired deviations due to dysthyroid ocular myopathy were injected with botulinum A toxin for relief of their diplopia. Seven patients were acute in the onset of symptoms and one was chronic. All showed improvement in motility and experienced a reduction if not total relief of their symptoms. Six patients required reinjection. Complications were limited to transient ptosis, transient involvement of adjacent muscles and transient but prolonged paralysis that eventually resolved. No systemic complications were noted. We conclude that chemodenervation with botulinum A toxin may have a role in the management of dysthyroid ocular myopathy not amenable to prism treatment and may act as an adjunct to or eliminate the need for surgical correction in some patients.

In 12 patients with minimal oculomotor nerve deficits due to unruptured intracranial aneurysm, the nerve-related findings were incomplete and at least one element (ptosis, mydriasis, or extraocular muscle weakness) was spared in every patient. Although symptomatic, the affected cranial nerve III functions were only partially lost. Six patients had ptosis and mydriasis, three had ptosis and diplopia, two had mydriasis and diplopia, and one had mydriasis alone. Eleven patients had accompanying headaches that were remarkably variable and difficult to categorize. Cerebral angiography showed the aneurysms, but computed tomography missed one third of them. The symptomatic aneurysm arose from the internal carotid artery in six patients, and from the distal basilar artery in six. Fragments of a cranial nerve III palsy associated with recent onset and ipsilateral headache suggest an enlarging internal carotid or distal basilar artery aneurysm.

Six weeks after a traffic accident a patient presented with enophthalmos of 6 mm on the right side, a marked divergent squint, and double vision in all directions of gaze. CT scans showed a posterior medial, and inferior fracture of the orbit with tissue prolapse. In the course of surgery it became clear that an antral balloon alone would not be sufficient to push back the prolapsed tissue in the ethmoidal region. For this reason an additional, smaller (Lincoff-Kreissig) balloon was inflated in this region. The procedure was successful.

Forty-eight patients were given serial injections of botulinum toxin in their eyelids for treatment of eyelid spasm during a two-year interval. Ninety-four percent obtained relief of spasm from botulinum toxin injection. The duration of the spasm-free interval as well as the incidence of ptosis and of diplopia was dose dependent. The marked increase in the incidence of these side effects with only a small increase in the duration of the spasm-free interval, when a dose of 25 units per lid was used, leads the authors to conclude that this dose is too high and should not be used. Since diplopia was most commonly caused by paresis of the inferior oblique muscle, and since blepharospasm usually can be controlled by excising the upper lid protractors, further studies are required to determine whether lower lid injection is necessary and, if it is found to be so, whether injecting only the lateral portion of the lid would be adequate.

We examined two sisters with lid retraction on adduction, the classic sign of levator-oculomotor synkinesis. In both women, the left eye was involved. No history of trauma or ocular surgery or complaints of diplopia were elicited, and both had good visual acuity and full ocular motility. Each exhibited 2 mm of left upper lid elevation on adduction and 4 to 6 mm of lid elevation on adduction with depression. In one of the sisters, 1 mm of ptosis was present in straight ahead gaze in the involved eye, which increased to almost 2 mm on abduction, but full levator function was observed. Four other family members in three consecutive generations were similarly affected, suggesting an autosomal-dominant mode of inheritance. To our knowledge, this type of isolated levator-oculomotor synkinesis has not been reported previously on a congenital and inherited basis.
