摘要:

A 62-year-old man had progressive visual loss from neurosyphilis while his optic disks appeared atrophic. At no time was there evidence of inflammation of the globe or of either optic disk. The presence of an extremely high IgG index and five oligoclonal bands in the cerebrospinal fluid indicated that the central nervous system was synthesizing antibody specific to Treponema pallidum. Recent investigations indicate that much larger doses of penicillin are necessary for adequate treatment of neurosyphilis than have been recommended previously.

摘要:

A 31-year-old Japanese male with unilateral bouts of transient visual loss lasting for variable periods of time has been observed. In spite of the prolonged duration of some of these attacks (the longest attack lasted 7 1/2 hours), the patient sustained a relatively small amount of functional damage to the retina. Although the exact mechanism underlying these bouts of transient visual loss remains unknown, a discussion of the possible causes of such episodes, as well as the reasons for the relative preservation of vision in spite of the length of these attacks, is included.

摘要:

A 32-year old diabetic female had unilateral reduced vision (20/30) in an eye having the ophthalmoscopic appearance of papillophlebitis of the optic nerve head. After an apparently benign course, with recovery, the optic disc became edematous again and a central retinal vein occlusion blinded the eye. Thereafter, an avascular bilobed mass progressively protruded from the optic nerve head. Computerized tomography demonstrated uniform thickening of the optic nerve from the globe through the optic canal. The radiographic appearance was consistent with an optic nerve glioma or meningioma. Spinal fluid, chest x-ray, and serum angiotensin converting enzyme activity were normal. Tuberculin skin test was positive. Optic nerve biopsy demonstrated a noncaseating granuloma and a subsequent Kveim test was positive. Isolated optic nerve sarcoidosis may exist without other systemic manifestations. The appearance on computerized tomography may be similar to that of an optic nerve glioma or meningioma.

摘要:

Five patients with the Eaton-Lambert syndrome were examined neuro-ophthalmologically. Three were studied using electro-oculographic saccadic velocity recordings. Four complained of blurred vision and all complained of ptosis during the course of their disease. Clinical examination revealed mild ptosis in three of the five patients. Saccadic velocities before exercise were normal. After saccadic exercise, an increase in velocity of up to 40% was noted in two of the three patients studied.

摘要:

The most common permanent neuro-ophthalmologic complication of cardiopulmonary bypass surgery is visual loss. Bilateral lower altitudinal visual field defects were documented in a patient who noted blurred vision following open heart surgery. A difference of opinion existed as to whether the field defects were due to retina-optic nerve or occipital lobe lesions. Two points are emphasized in this report: 1) the field defects were much easier to define on the tangent screen than on Goldman perimetry, and 2) occipital coronal high resolution CT scan confirmed bilateral upper bank calcarine cortex infarctions in this patient.Occipital coronal, thin-section, high-resolution computed tomographic scans are helpful in studying patients with occipital lobe visual field defects.

摘要:

Three cases of painful ophthalmoplegia with acute onset due to an unruptured aneurysm of the intracavernous portion of the internal carotid artery are reported. The possible pathogenetic mechanisms responsible for this unusual mode of clinical manifestation are discussed and the neurovascular relationships of the cavernous sinus are analyzed in respect of is-chemic versus compressive damage to the intracavernous neural structures.

摘要:

The Gunkel chromograph was tested on 81 volunteers with normal color vision as indicated by screening with Ishihara plates and the panel D-15. Most of these color normals located their neutral area superior to the geometric center of the chromogram. A minority located their neutral area at the geometric center. Recognition of this variation may prevent misdiagnosis of chromographs of patients suspected of having color vision defects. All 29 eyes with history and VEP findings consistent with optic nerve demyelinization had enlargement of the neutral area, even though visual acuity could be corrected to 20/20.

摘要:

An acute relapsing orbital inflammatory disease predominantly affecting the extraocular muscles was seen in two patients and is reported here as acute recurrent orbital myositis. The association of this disorder with other systemic diseases such as asthma, sinusitis, upper respiratory infection, Crohn's disease, and serum sickness is discussed. The similarities to other forms of acute orbital inflammatory disease such as orbital pseudotumor are noted, and a possible underlying immunologic mechanism is suggested.

摘要:

A patient with transient monocular rotary-vertical nystagmus demonstrated decreased gain of vertical pursuit and normal vestibulo-ocular reflex on electrooculogram. A supranuclear brain stem lesion, resulting in lack of monocular inhibition of oculomotor neurons, is postulated on the basis of these findings.
