摘要:

Three patients with developmental abnormalities of the optic disc (two morning glory anomalies and one retinochoroidal-optic disc coloboma) had angiographically documented aberrancies of the carotid circulation including large trunk occlusions, moya-moya-like collaterals, dolichoectasia, and absent ophthalmic artery. Although developmental optic disc abnormalities have been linked with other problems such as basal encephalocele, congenital heart defects, and eyelid hemangiomas, these three patients are the first to our knowledge to have related malformations of the intracranial circulation. We suggest, therefore, that the presence of a congenital optic disc anomaly may herald a similar defect in the cerebral circulation.

摘要:

A 38-year-old woman presented with a bilateral, chronic, progressive optic neuropathy following Jejunoileal bypass surgery for morbid obesity. Standardized A-scan orbital echography revealed grossly swollen optic nerve sheaths with a positive 30° test, indicating increased subarachnoid fluid. Review of reported complications of Jejunoileal bypass surgery revealed no similar case of what might be termed the “optic nerve ascites syndrome.”

摘要:

A case of Wegener's granulomatosis is reported which manifested episcleritis followed by scleritis, and followed in turn by separate episodes of right and left orbital pseudotumor spanning 15 years prior to respiratory tract disease. The unusually protracted progression of symptoms in this case may be explained on the basis of the histopathological findings. Areas of fibrinoid necrosis of connective tissue occurred alone or alternated with areas of nongranulomatous fibrinoid necrosis of blood vessel walls. Granulomatours vasculitis was not observed. This histopathological picture is pathog-nomic of early cases of Wegener's granulomatosis which run especially protracted courses.

摘要:

We present a case of gaze palsy caused by a pontine tuberculoma associated wih cryptic disseminated tuberculosis. The only symptoms in this patient were those caused by her gaze abnormality despite the presence of disseminated tuberculosis that was later confirmed at autopsy.

摘要:

A 24-year-old female developed bilateral internu-clear ophthalmoplegia with exotropia and loss of convergence, in association with a tuberculous granuloma situated in the midline midbrain at the level of the third ventricle. We labeled this case Webino (after Martin Lubow), and to our knowledge, this is the first reported case occurring in association with an intraparenchymal tuberculous granuloma.

摘要:

Optic nerve dysfunction occurred several weeks after traumatic carotid-cavernous fistula developed in a 21-year-old man. Vision was completely restored after the fistula was closed with an intra-arterial detachable balloon. By carefully monitoring visual function in patients with traumatic carotid-cavernous fistulas, delayed optic neuropathy can be recognized and treated successfully.

摘要:

Three patients with pseudotumor cerebri developed transient vertical ocular motor abnormalities. All had associated sixth nerve palsies and two had significant abnormalities of visual acuity and fields. Effective treatment of elevated intracranial pressure (ICP) resulted in resolution of the motility disturbance in all cases. This unusual oculomotor feature of elevated ICP may be due to skew deviation or fourth nerve palsy, but in either instance it is not a localizing sign.

摘要:

We report two cases of pseudotumor cerebri with subretinal hemorrhages. Bilateral Juxtapapillary subretinal neovascular membranes were present in one. A unilateral hemorrhage occurred adjacent to a small anomalous optic disc in the other. Subretinal hemorrhages in papilledema may occur from Juxtapapillary subretinal neovascular membranes that evolve rapidly and then involute. The relationship of the appearance and subsequent evolution of such Juxtapapillary subretinal neovascular membranes to the course of the intracranial pressure is discussed. Occurrence in one eye may presage occurrence in the other eye, making control of intracranial pressure important once one eye is afflicted. Fortunately, severe permanent visual loss remains unreported.Some anomalous small optic discs may be particularly at risk for subretinal hemorrhage from papilledema because preexisting axonal crowding is aggravated by the swelling of the optic nerve from elevated intracranial pressure.Conditions related to the Valsalva maneuver that chronically or intermittently elevate intracranial pressure further and produce elevated cephalic venous pressure should be avoided.

摘要:

A patient with bilateral trochlear nerve palsies is presented. Computed tomographic (CT) brain scan localized an anterior cerebellar vermis lesion compressing the area caudal to the inferior colliculi where the fourth nerves decussate and exit the dorsal brain stem. This lesion was probably responsible for the bilateral trochlear nerve dysfunction. Pertinent anatomy and pathologic involvement are discussed.
