A case of type I Arnold-Chiari malformation of anomalous onset.

A case of type I Arnold-Chiari malformation, with onset of diplopia, without associated medullar alteration, is presented. The symptomatology remained unique and had transitory presentation for many years with negative ophthalmic examinations. Attention is drawn to the great variability of the syndrome's presenting symptoms confirming the importance of MR in the diagnostic course and of evoked potentials of the brain stem to follow progress of the illness.

[Multiple and recurrent paralysis of cranial nerves: primary Gougerot-Sjögren syndrome].

Over a period of 10 years, a 49-year-old man had 3 episodes of recurrent cranial nerve palsy regressing within a few weeks. Each episode was accompanied with acute inaugural headache and diplopia and once with sensory impairment of the trigeminal nerf and once with tinnitus. The diagnosis of Goujerot-Sjögren's syndrome was retained after demonstration of hypergammaglobulinaemia, a positive Rose Bengale test and histological examination of biopsy specimens from the accessory salivary glands which revealed advanced typical lesions. Clinically, impaired secretion was not obvious.

Ophthalmic manifestations of vertebral artery dissection. Patients seen at the Mayo Clinic from 1976 to 1992.

PURPOSE: To determine the ophthalmic manifestations of vertebral artery dissections. METHODS: Fifty-one separate episodes of vertebral artery dissections evaluated at the Mayo Clinic from 1976 through 1992 were studied. In all cases, the diagnosis had been documented with angiography. RESULTS: There were 28 men and 19 women (mean and median age, 39 and 40 years, respectively; range, 8-61 years). There were ophthalmic findings in 86% of the episodes. Visual symptoms, in decreasing order of frequency, were diplopia (45% of the episodes), blurred vision (14%), transient visual dimming (8%), oscillopsia (4%), photophobia (4%), upside-down vision (2%), positional transient visual obscuration (2%), and unilateral dry eye (2%). Ophthalmic signs in decreasing order of frequency were nystagmus (37% of the episodes), ocular misalignment (cranial nerve palsy or skew) (33%), Horner syndrome (27%), decreased corneal sensation (22%), ptosis (16%), visual field defect (10%), abnormal pursuits and saccades (6%), ocular bobbing (4%), internuclear ophthalmoplegia (4%), anisocoria (4%), and pinpoint pupils (2%). CONCLUSION: Vertebral artery dissections occur in a relatively young population. Most of the patients in our study had ophthalmic manifestations at the time of diagnosis. Heightened awareness of this entity should enable the consulting ophthalmologist to have a role in the diagnosis and treatment of vertebral artery dissection.

[Diagnosis and results of treatment of blow-out fracture of the orbital floor].

In the last 20 years, 273 patients with blow-out fracture of the orbital floor were treated. Surgery was performed in 242 of them (88.6%). The typical features of this type of fracture as well as the methods and results of treatment are presented. Criteria of the recovery were disappearance of diplopia and decrease of enophthalmos.

[Pituitary abscess, treated by medication].

Pituitary abscesses are rare. The case reported here concerns a 28-year old African. Gradual development of diplopia over 6 months was the first clinical manifestation. Three months later this development had reached a more severe and infectious context, with complete right ophthalmoplegia, meningitis and coma (GCS = 9). CT scan showed an image in favour of a pituitary abscess with suprasellar extension, associated with thrombophlebitis of the cavernous sinus. An antibiotic therapy consisting of cefotaxime and metronidazole administered for 1 month, and netilmicin for 15 days succeeded in controlling the infectious syndrome. This resulted in cure of visual disorders, reduction in size of the CT scan image and reconstruction of the pituitary sella which had been destroyed. The diagnosis of pituitary abscess should be made when confronted with an infectious syndrome (unexplained fever, repeated meningitis). CT does not recognize the nature of the hypophyseal mass it shows: necrosis of a pituitary adenoma, giant aneurysm or craniopharyngioma may mimic local infection. Surgery confirms the diagnosis and is regarded as the best treatment. The patient's life is threatened when meningitis is present, and the functional prognosis is poor when recovery from visual disorders is compromised due to late diagnosis. In this paper a comparative analysis of the clinical course of the disease and therapeutic data in our patient is presented and compared with other reported cases.

Visual illusions and hallucinations.

Visual illusions and hallucinations may accompany a wide variety of disorders with many different aetiologies; therefore, they are non-specific phenomena. Lesions in the visual pathway may be associated with visual misperceptions. In these cases more exact information about the misperceptions--whether they are monocular or binocular, present in the whole visual field or a hemifield--may contribute to diagnostic accuracy and to a more comprehensive understanding of the patient and his state of mind. Illusions such as perseveration, monocular diplopia and polyopia, and dysmorphopsia may also occur in healthy individuals, but they are found most often in patients with epilepsy, migraine and stroke. These phenomena do not permit exact localization and definition of an aetiology, but lesions in the occipital and occipitotemporal regions near the visual pathway are involved in most cases. Hallucinations always represent a pathological form of perception. They are classified as unformed (photopsias) or formed (complex). Photopsias may be described in terms of colour, shape and brightness. Their wide variety makes it difficult, if not impossible, to arrive at an exact description of their aetiology, but it is possible to define their anatomical origin in some cases. Complex hallucinations suggest an occipitotemporal locus. Whether they appear in the whole visual field or in the hemifield may prove decisive in determining pathogenesis. A number of characteristics permit a rough classification of these phenomena. Complex hallucinations accompany physical illness and are susceptible to psychodynamic interpretation.

Sixth nerve palsy: an unusual manifestation of preeclampsia.

BACKGROUND: Neurologic abnormalities may occur in pregnancy as a manifestation of neurologic or systemic disease. We present an unusual case of preeclampsia presenting with a sixth nerve lesion. CASE: A 33-year-old woman, gravida 2, presented at 38 weeks' gestation with sixth nerve palsy. She was hypertensive and proteinuric, with plasma urea of 24 mg/dL. Labor was induced and hypertension escalated in the early puerperium, with concomitant worsening diplopia. Blood pressure control and resolution of preeclampsia were followed by resolution of the sixth nerve lesion. There was no evidence of other pathology on extensive investigations. CONCLUSION: Sixth nerve palsy is an unusual manifestation of preeclampsia.

Orbital emphysema. Staging and acute management.

BACKGROUND: Orbital emphysema is usually a benign, transient phenomenon. Rarely, the intraorbital air mass can cause central retinal artery occlusion. Because of the potential for severe visual loss, the rapid diagnosis and management of this condition are essential. Currently, there is no standard protocol for the treatment and management of severe orbital emphysema. To develop a management algorithm, the authors reviewed the records of eight patients with orbital emphysema, in addition to nine other reported patients with ocular dysfunction. METHODS: Retrospective review of patients with orbital emphysema who have proptosis, diplopia, or loss of vision. RESULTS: Orbital emphysema is associated with small orbital fractures. The location of the intraorbital air mass usually correlates with the fracture location. A four-stage classification system of orbital emphysema is developed. This staging system is helpful in constructing an acute diagnostic and management algorithm for orbital emphysema. CONCLUSION: Understanding the pathophysiology of orbital emphysema is important in developing a rational approach to manage this potentially sight-threatening condition. Treatment using a needle-coupled open syringe filled with saline allows direct monitoring of the air mass during decompression.

[A 62-year-old man with multiple cranial nerve palsies on the right side and a pelvic mass].

We report a 62-year-old man with a pelvic mass, who developed multiple cranial nerve palsies on the right side. He was well until the summer of 1977 when he developed a numb sensation in the sacral region. In the next year, a huge tumor was found in the sacral area in another hospital. Most of the tumor was resected at that time. Post-operative course was uneventful. In July 1988, there was an onset of weakness in his legs, gait disturbance, and dysuria. Myelography at the above hospital revealed a complete block at the seventh thoracic level. He was treated by laminectomy and post-operative radiation. In June 1990, he developed a neuralgic pan in his right leg. Two months later, he noted diplopia, deafness in his right ear, and swallowing difficulty. He was admitted to our hospital for further work up on January 14th of 1991. On admission, he was afebrile. General physical examination revealed a 4 cm had mass in his right anterior chest attaching the rib. Gynecomastia was noted bilaterally. Liver was felt by 5 cms under the right hypochondrium. The edge of the liver was firm. On neurologic examination he was an alert and mentally sound man. His higher cerebral functions were intact. In the cranial nerves, complete palsy of the abducens nerve, mild nerve deafness, paresis of the soft palate, atrophy and weakness of the sternocleidomastoid and upper trapezium muscles, all on the right side, deviation of the tongue to the right, slurred speech, and dysphagia were observed. The neck was supple. He was able to walk with a support. Mild weakness was present in his right lower extremity. Both legs were spastic. No ataxia or involuntary movements were noted. Deep reflexes were symmetric and normally active. No sensory loss was observed. No meningeal signs were present. Pertinent laboratory findings included moderate anemia (Hb 8.8 g/dl), LDH 2,631 U/l, CRP 7.4 mg/dl. The CSF was under an increased pressure (OP 260 mmH2O) containing 2 lymphocytes/ml, 43 mg/dl of protein, and 49 mg/dl of glucose. Radiologic examinations revealed a destructive change in the sacrum, lytic lesions in the seventh thoracic spine and in the clivus.(ABSTRACT TRUNCATED AT 400 WORDS)

Is there a need for binocular vision evaluation in low vision?

The purpose of this study was to determine the need for a binocular vision evaluation in the management of low vision patients. Thirty subjects were selected with visual acuities of at least 6/60 in each eye. Twenty-three had age-related macular degeneration as the primary ocular pathology and seven had various other ocular conditions. The binocular vision evaluation comprised: detailed history and symptoms with an emphasis on the occurrence of near vision problems; modified binocular vision assessment which included cover test at near, ocular movements, convergence, Bagolini glasses, horizontal vergence reserves and prismatic measurement of any observed anomaly. History and symptoms revealed horizontal and vertical diplopia, jumbling of print, asthenopia, intermittent blurring and print being too small. Binocular vision assessment revealed exophoria at near, manifest horizontal deviations, convergence insufficiency, and vertical muscle imbalance. These anomalies occurred either singly or in combination. The results indicate that there is a need for binocular vision evaluation in low vision in order to reveal near vision disorders that may be partly attributable to binocular vision anomaly and not solely due to ocular pathology. This information should facilitate the implementation of the appropriate course of optometric management for these patients.

Evenoming by Bungarus multicinctus (many-banded krait) in Hong Kong.

We describe the clinical course of two cases of envenoming by the many-banded krait (Bungarus multicinctus). A man developed generalized paralysis and respiratory failure with transient hypertension. Nerve conduction studies revealed normal motor and sensory conduction velocities with reduced motor unit action potential amplitudes consistent with neuromuscular blockade. He showed a slight transient response to the banded krait (B. fasciatus) antivenom but required ventilatory support for 8 days. After the fourth day, there was some response to treatment with anticholinesterase. Another man developed diplopia, dysphagia and leg weakness but recovered spontaneously after 48 hours.

[Multiple myeloma presenting as parasellar syndrome and cranial nerve palsies].

Cranial and intracranial locations have been rarely reported in multiple myeloma. Their occurrence as a harbinger of multiple myeloma seems to have a particular significance. In this report, we discuss a case of multiple myeloma presenting as parasellar syndrome and cranial nerve palsies. A 75-year-old woman was admitted to the hospital in June, 1994, with a 3-month history of headache and a 3-week history of diplopia and photophobia. Physical examination revealed right third, fourth and sixth cranial nerve palsies. MRI scan demonstrated a homogeneous, voluminous mass, isointense in T1-weighted images with the cerebral parenchyma and hyperintense in T2-weighted images, occupying the sphenoid sinus and extending within the sella turcica and right cavernous sinus. Lying above the mass and apparently separated from it by a thin rim of hypointensity was a normal pituitary gland. X rays revealed destructive changes of the sella turcica. A minimal disturbance of endocrine function together with a radiologically abnormal pituitary fossa indicated that the primary lesion might lie outside the pituitary fossa. A diagnosis of IgG-kappa type multiple myeloma was made by pertinent laboratory studies. She received local radiation to the intracranial mass (50 Gy) and conventional chemotherapy. Sixteen months after the therapy she is in good health.

Do patients with facial trauma to the orbito-zygomatic region also sustain significant ocular injuries?

A retrospective study of orbito-zygomatic injuries presenting to eye casualty over 3-year period revealed the majority of patients with pure orbital "blow-out' fractures had no other associated ocular abnormalities and 96% of these patients had a visual acuity of 6/9 or greater at discharge. In contrast only 74% of patients with multiple facial fractures had a visual acuity of 6/9 or greater at discharge. Severe ocular trauma was uncommon in patients with orbito-zygomatic injuries. Decrease in visual acuity was the main clinical finding accompanying significant eye injury. Early ophthalmic assessment is recommended in these cases to exclude potentially serious complications such as traumatic optic neuropathy. All patients with blow-out fractures managed conservatively had complete resolution of troublesome diplopia without extra-ocular muscle surgery.

Ocular neuromyotonia--an unusual ocular motility complication after radiation therapy for nasopharyngeal carcinoma.

The incidence of nasopharyngeal carcinoma is high amongst the Chinese population in Singapore. Abnormal ocular motility, like abducens nerve palsy, is often a presenting feature. Ocular motility problems can also arise as a complication from the treatment or tumour recurrence. This is a case report of a patient who had been treated for nasopharyngeal carcinoma with radiotherapy 13 years ago. She presented with paroxysmal diplopia and the clinical findings were consistent with ocular neuromyotonia. She responded favourably to oral carbamazepine. Ocular neuromyotonia is uncommon and it has never been reported in the local literature. Recognition of the condition is of both diagnostic and therapeutic significance.

Strabismus induced by radial keratotomy.

The history of a woman who developed diplopia after radial keratotomy is reported. Examination showed that this was the result of the appearance of accommodative esotropia. Some complications of refractive surgery reported in the literature were reviewed. It is the current policy of the U.S. military services to disquality an applicant for entry who has undergone refractive surgery. Based on this review of complications it is argued that this is still the correct policy.

[A case of Nothnagel syndrome].

A 72-year-old woman developed a sudden onset of bilateral ptosis, diplopia and gait disturbance. Neurological examination revealed bilateral oculomotor palsies, truncal ataxia, and transient slight weakness in the right upper extremity. She was diagnosed to have Nothnagel syndrome. T2-weighted MRI disclosed a high signal intensity lesion at the left paracentral portion of the upper midbrain in addition to the bilateral medial thalamic lesions, while brain CT showed only the thalamic lesions. Brain MRI was useful for detecting the small midbrain lesion.

[Ophthalmologic causes of traffic accidents].

The review deals with association of traffic accidents and visual state of drivers. The study in healthy professional drivers covered influence of visual defect patterns (short sight, lower visual acuity, unilateral amblyopia and single eye) on quality of car driving. The driving quality appeared to be influenced by factor causing lower visual acuity (changes in refraction and opacity of transparent eye structures). Binocular vision plays insignificant role in driving and maneuvering. Lower quality of maneuvering results mainly from diplopia, but not from loss of stereoscopic vision.
