摘要:

&NA;A case is presented in which Horner syndrome occurred on the side of the larger pupil in underlying physiologic anisocoria. The unusual coincidence resulted in ipsilateral ptosis, but with clinically equal‐sized and normally reactive pupils.

摘要:

&NA;Myasthenia gravis (MG) is a neuromuscular disorder that affects skeletal muscles, in particular, the extraocular muscles. Response variability is a hallmark sign. Detailed findings are described in a patient with MG in which the presenting sign was accommodative insufficiency. Objective accommodative findings were recorded 3 years before the onset of myasthenia, soon after the initial diagnosis was made, and then after the treatment commenced with pyridostigmine. In addition, clinical measurements were obtained periodically at different times of the day for various binocular motor functions, including near point of convergence, phoria, fusional and accommodative amplitudes, and relative accommodation. The disease adversely affected all accommodative and vergence findings, with fatigue being the primary disturbance. The therapeutic administration of pyridostigmine improved static measurements of accommodation and vergence and reduced asthenopia. The objective dynamic measurements of accommodation, vergence, and versions were less affected. These findings provide a clear demonstration that both intrinsic and extrinsic ocular muscles may be affected in the prepresbyopic myasthenic patient.

摘要:

Objective:To inform clinicians about the use of magnetic resonance (MR) venography in idiopathic pseudotumor cerebri.Materials and Methods:A prospective study to evaluate for the presence or absence of dural sinus thrombosis using MR imaging and MR venography of the brain in 22 consecutive young, female, overweight patients with typical pseudotumor cerebri.Results:None of the 22 MR imaging and MR venography studies showed venous sinus thrombosis.Conclusion:Magnetic resonance venography might not add significantly to the evaluation of typical idiopathic pseudotumor cerebri but may be indicated in atypical cases (e.g., male, thin, or elderly patients).

摘要:

&NA;In a 25‐year‐old woman with episodic periorbital‐temporal pain who eventually developed a sixth nerve palsy, magnetic resonance imaging revealed a lesion predominantly in the Meckel cave that was found to be a capillary hemangioma arising from the mandibular division of the trigeminal nerve. Hemangiomas of the Meckel cave must be considered in cases of facial pain with a sixth nerve palsy, even if there are no clinical findings of trigeminal neuropathy.

摘要:

&NA;Arteriovenous malformations (AVMs) are anomalous communications between arterial and venous systems without interposed capillaries. These lesions are rarely entirely intraorbital. A case of an arteriovenous communication between branches of the internal and external carotid arterial circulations and the ophthalmic veins located within the orbit is reported. Treatment with embolization resulted in a branch retinal artery occlusion. Attempted direct arterial occlusion of a dural‐based fistula of the eye is a risky procedure. If embolized, AVMs should probably be approached from the venous side, if at all.

摘要:

&NA;A 52‐year‐old patient experienced unilateral third nerve palsy because of cavernous sinus involvement of biopsy‐proven esthesioneuroblastoma. The patient experienced resolution of diplopia after surgical debulking of the tumor. Clinicians should be aware of the neuro‐ophthalmologic manifestations of esthesioneuroblastoma.

摘要:

&NA;Master Jehan Yperman, a medieval surgeon, observed that when the optic nerve is injured, the eye becomes blind and beautiful. This is an attempt to trace the footsteps of this forgotten surgeon and to track the history of the cosmetic use of the belladonna herb, as well as the concept of amaurotic mydriasis.

摘要:

&NA;The presence of increased subarachnoid fluid around the optic nerve as measured by ultrasound has been shown to be associated with elevated intracranial pressure, as well as a number of other conditions. This finding has proved useful for distinguishing optic disc elevation secondary to papilledema from disc elevation attributable to other causes. This report describes a patient with anomalous optic disc elevation and increased subarachnoid fluid around the optic nerve.

摘要:

&NA;Visual loss in patients with encephalotrigeminal angiomatosis or Sturge‐Weber syndrome usually results from secondary glaucoma or from damage to the retrogeniculate pathways by the angiomatous lesions. Optic neuropathy has not been reported as a component of this syndrome. This report describes a patient who developed bilateral optic neuropathy with progressive visual loss associated with diffuse cerebral angiomatosis in the setting of Sturge‐Weber syndrome.
