Autoimmune ischemic optic neuropathy associated with positive rheumatoid factor and transient nephrosis.

A young woman had recurrent anterior ischemic optic neuropathy for 18 years. During a recent episode of severe papillopathy in one eye, acute glomerulonephritis, transient low serum complement levels, and a high rheumatoid factor were detected. Despite long and careful follow-up, we could not diagnose systemic lupus erythematosus or any other specific connective tissue or autoimmune disease. We suspect transient disordered immunity may have contributed to provoking acute anterior ischemic optic neuropathy concomitant with acute glomerulonephritis despite the absence of generalized connective tissue disease. An extensive search for immunologic mechanisms in some patients with presumed idiopathic anterior ischemic optic neuropathy may be warranted because immunosuppressive treatment may be beneficial in preventing recurrences.

Mydriasis in giant-cell arteritis.

A previously healthy 60-year-old woman developed headache, cervical pain, bilateral mydriasis (right greater than left), and bilateral conjunctival injection as the sole manifestations of acute giant-cell arteritis.

Autoimmune endotheliopathy and chronic herpetic conjunctivitis.

A migrating endothelial line of keratic precipitates associated with overlying corneal edema suggests an immune attack on the corneal endothelium. This is seen most commonly in corneal allotransplantation rejection. The etiology of such lines in the absence of this condition is unclear. We document the presence of an intranuclear virus compatible with herpesvirus in this condition.

Chronic syphilitic meningitis resulting in superior orbital fissure syndrome and posterior fossa gumma. A report of two cases followed for 20 years.

Two case histories, each spanning more than 20 years, demonstrate the complexity and persistence of modern neurosyphilis. Both patients present uncommon manifestations of neurosyphilis that may be easily overlooked today: superior orbital fissure syndrome, posterior fossa gumma, and bilateral deafness. Computed tomographic scans were performed in both patients but were diagnostically nonspecific, and syphilis serology testing in both serum and cerebrospinal fluid was repeatedly misleading. Numerous mistaken diagnoses were put forward until tissue was finally available for histologic examination. Perhaps the most disturbing aspects of these two cases are the persistent failure of specific treponemal serologic testing to indicate the diagnosis, and the inability of repeated "adequate" and/or supramaximal doses of penicillin to prevent continued neurologic deterioration. We believe that chronic neurosyphilis may demand a reevaluation of current diagnostic and therapeutic practice.

Optic neuropathy associated with chronic lymphomatous meningitis.

A patient with paranasal sinus lymphoma (recognized retrospectively) developed unilateral, acute, self-limited optic neuritis during the course of chronic lymphocytic meningitis with elevated intracranial pressure and headache. Meningeal symptoms were adequately controlled with analgesics alone for 14 months and corticosteroids alone for a subsequent 11 months without evidence of development of other involvement of organs outside the central nervous system (CNS). Eventually, the visual alteration from optic neuritis prompted a repeat evaluation, which disclosed lymphoma in bone marrow. The subject of paraneoplastic optic neuritis is reviewed.

Anterior ischemic optic neuropathy in Buerger's disease.

A 77-year-old man with a history of Buerger's disease developed an anterior ischemic optic neuropathy. This disease, while rare in the United States at the present time, is common in other parts of the world. None the less, this appears to be the first reported case of this type of optic neuropathy in a patient with documented Buerger's disease. A possible mechanism is suggested.

Vascular retinopathy in migraine.

After years of episodic monocular visual loss, two migraineurs suffered sudden, persisting loss of vision from retinal vascular occlusion. One was a 34-year-old woman with systemic lupus erythematosus who showed abnormalities of the cilioretinal arterial and retinal venous circulations. The other was a 62-year-old man with hypertension and arteriosclerosis who had a central retinal vein occlusion. Persisting monocular visual loss is a rare consequence of migraine. Our cases suggest a role for venous lesions. Occlusion of retinal vessels in some migraineurs may result from the synergistic effect of another vascular disorder with the migraine.

Neovascular glaucoma and carotid artery obstructive disease.

Carotid artery obstructive disease, although infrequently diagnosed as a primary or contributing cause of neovascular glaucoma, can produce distinctive characteristics. Decreased perfusion of the ciliary body may decrease aqueous humor production. As a result, such eyes with neovascular glaucoma may occasionally be normotensive or even hypotensive. Fluorescein angiography may show an increased arm-to-retina time and leakage from the major retinal arterioles. Panretinal photocoagulation may not eliminate the anterior segment neovascularization because of anterior segment ischemia. Endarterectomy can significantly increase intraocular pressure as perfusion to the ciliary body returns to normal. These characteristics were found in two patients, a 67-year-old woman and a 49-year-old man, with diabetes and hypertension. In both cases cyclocryotherapy significantly reduced the intraocular pressure and the rubeosis iridis regressed.
