1/80. Pituitary macroadenoma manifesting as an isolated fourth nerve palsy.

    PURPOSE: To describe an unusual ophthalmic manifestation of a pituitary adenoma. methods: Case report. RESULTS: A 32-year-old man had left supraorbital and frontal headaches and new-onset vertical diplopia. Examination showed a left fourth nerve palsy and increased vertical fusional amplitudes. magnetic resonance imaging disclosed a sellar mass consistent with a pituitary macroadenoma. CONCLUSION: A pituitary adenoma may rarely manifest with an isolated fourth nerve palsy.

2/80. Spontaneous intracranial hypotension.

    PURPOSE: To describe a patient with classic presentation of spontaneous intracranial hypotension and subsequent improvement with targeted epidural blood patch. methods: Report of one case and review of the literature. RESULTS: Examination of cerebrospinal fluid after lumbar puncture disclosed a reduced opening pressure, an increased level of protein, and lymphocytic pleocytosis. magnetic resonance imaging of the brain with gadolinium showed diffuse enhancement of the pachymeninges, no evidence of leptomeningeal enhancement, and chronic subdural fluid collection. Radionuclide cisternography demonstrated reduced activity over the cerebral convexities, early accumulation of radiotracer in the urinary bladder, and direct evidence of leakage at the cervicothoracic junction (C7-T1). Clinical, laboratory, and radiologic features were consistent with the diagnosis of spontaneous intracranial hypotension. Therapy with a targeted epidural blood patch resulted in the rapid resolution of symptoms. CONCLUSIONS: In this report, we describe a classic case of spontaneous intracranial hypotension in a 63-year-old man with an initial presentation of postural headaches, blurred vision, pain in the left eye, diplopia on left gaze, and neck soreness.

3/80. Rosai-Dorfman disease presenting multiple intracranial lesions with unique findings on magnetic resonance imaging. Case report.

    Rosai-Dorfman disease (RDD) is a rare idiopathic histoproliferative disease affecting the systemic lymph nodes. Although an extranodal lesion has also been recognized, central nervous system involvement is extremely rare. To the authors' knowledge, only 20 cases of intracranial lesions have been reported previously. Intracranial RDD is clinically and radiologically difficult to distinguish from meningioma, and histological examination is essential for a definitive diagnosis. The authors treated a large frontal lobe tumor associated with multiple meningeal nodules in a 67-year-old patient presenting with diplopia and headache. Radiological examination indicated that the mass was an inflammatory lesion rather than a meningioma. Microscopically the lesion consisted of mixed inflammatory infiltrate with marked emperipolesis, which is characteristic of RDD. A review of the literature and a discussion of the differential diagnosis of this rare lesion are also presented.

4/80. Castleman disease presenting with ophthalmic signs and symptoms.

    PURPOSE: To describe a patient with multicentric Castleman disease who was initially examined with ophthalmic signs and symptoms. methods: Case report. A 71-year-old man was initially examined with swelling of both upper eyelids and diplopia of 2 months' duration. RESULTS: Medical evaluation and right axillary lymph node biopsy disclosed Castleman disease. Systemic corticosteroid treatment temporarily resolved signs and symptoms, but the patient died of recurrence with cytomegalovirus and aspergillus infection 10 months after initial examination. CONCLUSIONS: Multicentric Castleman disease is a rare but distinct disorder that may present initially with ocular signs and symptoms. This disease must be included in the differential diagnosis of orbital pseudotumor and lymphoma.

5/80. Divergence paralysis & intracranial hypertension due to neurobrucellosis. A case report.

    CASE REPORT: A 22 year old female presented with sudden onset of uncrossed diplopia at distance, intracranial hypertension, esotropia and was evaluated. Microbiological tests of CSF and sera showed for brucellosis and the patient received therapy for this and her intracranial hypertension. The papilledema, headache, esotropia and diplopia all disappeared after therapy. CONCLUSIONS: Diagnostic tests for brucella must be considered for patients who have divergence palsy and papilledema, especially those living in endemic areas.

6/80. Fresnel membrane prisms: clinical experience.

    BACKGROUND: There are few published reports on the clinical application of Fresnel membrane prisms in the treatment of diplopia in adults. The authors describe the use of these prisms in patients with fourth and sixth cranial nerve palsies, restrictive motility caused by thyroid-related orbital disease, and convergence insufficiency. methods: Of 209 patients who had been treated with Fresnel prisms, 141 were selected. The database included patients from a private practice in Montreal, seen from 1988 to 1996, and patients seen by orthoptists in the ophthalmology department of a children's hospital in Montreal between 1992 and 1996. All the patients had diplopia associated with fourth (48 patients) or sixth (43 patients) cranial nerve palsy, thyroid-related orbitopathy (18 patients) or convergence insufficiency (32 patients). After qualitative and quantitative assessment of the ocular misalignment, a Fresnel prism was selected for power and axis and for appropriate location on the spectacle lens. Ocular dominance and side of paresis or restriction were also considered in the placement of the prism. The patient's response to treatment was documented. RESULTS: The Fresnel prisms were oriented horizontally in 72 patients (51%), vertically in 55 (39%) and obliquely in 14 (10%). They were placed on the spectacle lens before the nondominant eye in 127 cases (90%), either covering the entire lens, or on the upper or lower segment or both. The patients were followed for an average of 15 (range 2 to 96) months. Of the 141 patients 113 (80%) had a successful outcome, with relief of their diplopia. Twenty-seven patients (19%) eventually had the prismatic correction ground into the lens, 70 (50%) chose to wear the Fresnel prism on a permanent basis because incorporation into the lens was not possible or because of cost, and 17 (12%) used the Fresnel prism as a temporary device before or after surgery. Most patients who converted to incorporated prisms did so when the prismatic power became stable, usually after 6 to 8 months. Eight patients (6%) stopped using the prism because of associated side effects, such as blurred vision, persistent diplopia, torsion or optical aberrations. INTERPRETATION: The Fresnel prism is an excellent device in treating diplopia in adult patients. It is a reasonable permanent option when incorporating the prism into the spectacle lens is not possible. A fused blurred image caused by a Fresnel prism placed in front of the nondominant eye is preferable to double but clear images.

7/80. Orbital emphysema and diplopia following thoracotomy.

    PURPOSE: To describe the clinical and radiological findings in a patient with diplopia and orbital emphysema following thoracotomy. methods: Reported is a 71-year-old woman who presented with diplopia several days following thoracotomy. RESULTS: physical examination revealed diffuse subcutaneous emphysema and a right hypertropia. Head computed tomography revealed facial and palpebral subcutaneous emphysema extending into the infratemporal fossa and orbits bilaterally. A chest tube was replaced and her diplopia resolved. CONCLUSIONS: subcutaneous emphysema can lead to diplopia and orbital emphysema in the absence of orbital trauma. Contrary to previously suggested mechanisms of orbital emphysema associated with subcutaneous emphysema, computed tomography imaging suggested that air entry into the orbit in this case was through the inferior orbital fissure.

8/80. Cranial nerve palsy and intracranial subdural hematoma following implantation of intrathecal drug delivery device.

    BACKGROUND AND OBJECTIVES: Complications related to cerebrospinal fluid (CSF) leak and low CSF pressure can occur following placement of an intrathecal drug delivery device. methods: A 58-year-old man with chronic, intractable lower back pain underwent implantation of an intrathecal drug delivery device. On the fourth postoperative day, he developed a postural headache and diplopia with findings compatible with left sixth cranial nerve palsy. The headache subsequently became constant and nonpostural. Cranial magnetic resonance imaging was obtained that showed the presence of a posterior subdural intracranial hematoma. Conservative treatment for postdural puncture headache did not improve the symptomatology. Therefore, an epidural blood patch was performed that produced rapid improvement and eventual resolution of symptoms. CONCLUSIONS: Intrathecal catheter implantation can result in CSF loss that might not resolve promptly with conservative therapy. In this case, epidural blood patch proved to be a safe and effective form of treatment.

9/80. Fronto-orbitonasal intradiploic meningioma in a child.

    Intradiploic meningioma, which may be classified as a subgroup of intraosseous meningioma, is a rarely encountered disorder. To date, less than 10 cases have been reported. Here, we report a case of fronto-orbitonasal intradiploic meningioma. A 12-year-old female with exophthalmos and diplopia was operated on for a cranial intradiploic mass lesion. Histopathological evaluation of the specimen confirmed the diagnosis of intradiploic psammomatous meningioma. Her exophthalmos did not change, but the diplopia disappeared. This case is unique in that it is an extensive case of intradiploic meningioma of the orbital roof and frontal base in a child. Intradiploic meningiomas generally are of psammomatous type. Especially tumors adjacent to the orbita cause exophthalmos; cases located on the other side of the calvarium may not cause any symptom or sign other than headache or sometimes a mass on the scalp. Treatment, as with meningiomas located in the intracranial cavity, is total resection of the lesion.

10/80. blepharoptosis-induced superior keratoconus.

    PURPOSE: This clinical case report demonstrates blepharoptosis-induced corneal steepening and its subsequent resolution after blepharoptosis surgery. methods: A 62-year-old man complaining of blurred vision without apparent cause on clinical examination underwent keratometry and computerized corneal topography, which revealed superior corneal steepening in both eyes. Bilateral upper eyelid blepharoptosis surgery was performed. RESULTS: Three months after blepharoptosis surgery, repeat computerized corneal topography revealed normal corneal contours with improved vision in both eyes. CONCLUSIONS: blepharoptosis is a common condition that may induce superior corneal ectasia that is not evident by manifest refraction, slit-lamp examination, or keratometry. Computerized corneal topography can help detect such subtle corneal abnormalities and guide therapy.
