The expanding ophthalmologic spectrum of Lyme disease

The Uveo-Meningeal Syndromes

BACKGROUND

The uveo-meningeal syndromes are a group of disorders that share involvement of the uvea, retina, and meninges.

REVIEW SUMMARY

We review the clinical manifestations of uveitis and describe the infectious, inflammatory, and neoplastic conditions associated with the uveo-meningeal syndrome.

CONCLUSIONS

Inflammatory or autoimmune diseases are probably the most common clinically recognized causes of true uveo-meningeal syndromes. These entities often cause inflammation of various tissues in the body, including ocular structures and the meninges (eg, Wegener granulomatosis, sarcoidosis, Behcet disease, Vogt-Koyanagi-Harada syndrome, and acute posterior multifocal placoid pigment epitheliopathy). The association of an infectious uveitis with an acute or chronic meningoencephalitis is unusual but occasionally the eye examination may suggest an infectious etiology or even a specific organism responsible for a meningeal syndrome. One should consider the diagnosis of primary ocular-CNS lymphoma in patients 40 years of age or older with bilateral uveitis, especially with prominent vitritis, that fails to respond to treatment or who has associated neurologic findings. A paraneoplastic disorder has been described in patients who have combined optic neuritis and retinitis defined serologically by the presence of a paraneoplastic IgG autoantibody CRMP-5-IgG. These patients may have an inflammatory vitritis and may have signs of cerebrospinal fluid inflammation.

Lyme disease complicated with pseudotumor cerebri

To our knowledge, pseudotumor cerebri as a complication of Lyme disease has been described only in children. We report the first case of an adult with pseudotumor cerebri due to Lyme disease and the use of serial lumbar punctures as the sole therapy.

Central nervous system Lyme disease

Lyme disease is a disease caused by the spirochete, Borrelia burgdorferi. It is transmitted to humans via a bite from an infected tick. It has several classic stages or categories of illness, including early localized disease, early disseminated disease, and late disease. The focus of this article is on the manifestations, diagnosis, and treatment of Lyme disease of the central nervous system.

Optic neuropathy in children with Lyme disease

Involvement of the optic nerve, either because of inflammation or increased intracranial pressure, is a rare manifestation of Lyme disease. Of the 4 children reported here with optic nerve abnormalities, 2 had decreased vision months after disease onset attributable to optic neuritis, and 1 had headache and diplopia early in the infection because of increased intracranial pressure associated with Lyme meningitis. In these 3 children, optic nerve involvement responded well to intravenous ceftriaxone therapy. The fourth child had headache and visual loss attributable to increased intracranial pressure and perhaps also to optic neuritis. Despite treatment with ceftriaxone and steroids, he had persistent increased intracranial pressure leading to permanent bilateral blindness. Clinicians should be aware that neuro-ophthalmologic involvement of Lyme disease may have significant consequences. If increased intracranial pressure persists despite antibiotic therapy, measures must be taken quickly to reduce the pressure.

Symptomatic intraocular inflammation in multiple sclerosis

PURPOSE

The aim of this study was to determine the type and outcome of uveitis in patients with multiple sclerosis.

METHODS

A retrospective study of 16 patients attending the uveitis clinic who had a clinically definite diagnosis of multiple sclerosis and symptomatic intraocular inflammation. The type of uveitis and complications present as well as the outcome of therapeutic intervention, either medical or surgical, was determined.

RESULTS

Chronic, bilateral anterior uveitis was present in six patients. Secondary cataracts requiring surgery occurred in 10 eyes, and trabeculectomy was done on five eyes for secondary glaucoma. Symptomatic vitritis (visual blurring and/or visually significant floaters) occurred in eight patients and was bilateral in four. Occlusive peripheral retinal vasculitis with subsequent areas of ischaemia and neovascularization requiring panretinal laser photocoagulation developed in eight eyes, five of which also required vitrectomy. Other posterior segment complications included macular oedema (four) and epiretinal membrane involving the macula (two). Five patients required systemic steroids for control of posterior uveitis. The median visual improvement following cataract surgery or vitrectomy was 3 Snellen lines to a median visual acuity of 6/18.

CONCLUSIONS

A wide range of clinical patterns of uveitis, which may be both symptomatic and sight-threatening, occur in patients with multiple sclerosis. In addition, the complications of uveitis may cause significant visual morbidity, much of which is amenable to appropriate surgical intervention. It is important that these potentially remediable conditions are recognized and treated to ensure that patients with multiple sclerosis retain optimum visual function.

Tick-borne diseases

Tick-transmitted infectious agents have assumed increased importance as causes of human disease in the United States. During the past two decades, Lyme borreliosis, ehrlichiosis, and babesiosis have emerged as newly described tick-borne infectious diseases of significance for pediatricians and pediatric neurologists. In fact, the highest rates of infection for Lyme disease and Rocky Mountain spotted fever (RMSF), by decade of age, are in childhood. As such, tick-borne infectious disease are of considerable public health concern, particularly for children residing in endemic regions. RMSF and human ehrlichioses can be life-threatening but are also eminently treatable when recognized early. Delays in diagnosis and treatment can lead to adverse outcomes. This article reviews the clinical and epidemiological features of Lyme borreliosis, RMSF, and ehrlichiosis, important causes of neurological illness among children, and summarizes current therapeutic and preventive strategies.

Glaucoma associated with uveitis

Raised intraocular pressure is a common and frequently serious complication of anterior uveitis. The milieu of inflammatory cells, the mediators they release, and the corticosteroid therapy used to treat the uveitis can participate in the pathogenesis of uveitic glaucoma. These factors alter the normal anatomic structure of the anterior chamber and angle, influencing aqueous production and outflow. These changes act to disrupt the homeostatic mechanisms of intraocular pressure control. Structural changes in the angle can be acute, such as in secondary angle closure with pupillary block glaucoma, or chronic, such as combined steroid-induced and secondary open angle glaucoma. Management of uveitic glaucoma may be difficult because of the numerous mechanisms involved in its pathogenesis. Diagnostic and therapeutic decisions are guided by careful delineation of the pathophysiology of each individual case. The goal of treatment is to minimize permanent structural alteration of aqueous outflow and to prevent damage to the optic nerve head. This article reviews the pathogenesis of uveitic glaucoma, with specific attention to etiology. Medical and surgical therapies are also discussed, with emphasis on the more recent developments in each category.

Patterns of uveitis as a guide in making rheumatologic and immunologic diagnoses

OBJECTIVE

To describe the patterns of clinical presentation in a series of 407 patients with uveitis and to establish the relationship between these patterns and the final diagnosis.

METHODS

Patients were referred to the Uveitis Clinic of a tertiary hospital from January 1992 to January 1996. All patients received a complete ophthalmologic examination, and a general clinical history was obtained. The current International Uveitis Study Group classification system was used for anatomic classification. To establish the final diagnosis of the most common entities causing uveitis, current diagnostic criteria were used. A discriminant analysis, with diagnostic grouping as the outcome variable and the clinical presentation features as discriminating variables, was performed.

RESULTS

With our classification system, 66.5% of the cases could be correctly classified according to the clinical pattern and morphologic findings. By diagnostic groups, discriminant analysis showed that 75% of patients with Behçet's disease, 77.1% of those with spondylarthropathy (including inflammatory bowel disease), 33.3% of those with sarcoidosis, 97.9% of those with toxoplasmosis, 85.7% of those with Vogt-Koyanagi-Harada syndrome, 100% of those with herpes, and 50.4% of those with idiopathic uveitis were correctly classified. In the miscellaneous group, which included disease entities with fewer than 5 cases, 42.9% were correctly classified.

CONCLUSION

Rheumatologic evaluation of the patient with uveitis can be more cost-effective if the referring ophthalmologist follows the classification system described herein, allowing a tailored approach in which only specific and necessary diagnostic tests are used.

Ocular manifestations of Lyme disease

Although ocular manifestations of Lyme disease have long been noted, they remain a rare feature of the disease. The spirochete invades the eye early and remains dormant, accounting for both early and late ocular manifestations. A nonspecific follicular conjunctivitis occurs in approximately 10% of patients with early Lyme disease. Keratitis occurs often within a few months of onset of disease and is characterized by nummular nonstaining opacities. Inflammatory syndromes, such as vitritis and uveitis, have been reported; in some cases, a vitreous tap is required for diagnosis. Neuro-ophthalmic manifestations include neuroretinitis, involvement of multiple cranial nerves, optic atrophy, and disc edema. Seventh nerve paresis can lead to neurotrophic keratitis. In endemic areas, Lyme disease may be responsible for approximately 25% of new-onset Bell's palsy. Criteria for establishing that eye findings can be attributed to Lyme disease include the lack of evidence of other disease, other clinical findings consistent with Lyme disease, occurrence in patients living in an endemic area, positive serology, and, in most cases, response to treatment. Management of ocular manifestations often requires intravenous therapy.

Long-term effects of ceftriaxone treatment on intraocular Lyme borreliosis

Twelve patients with intraocular Lyme borreliosis suffering from vitreitis were treated with ceftriaxone intravenously. Eight patients had definitive Lyme borreliosis, and tentative diagnosis was made in four patients. After treatment with ceftriaxone, all 12 patients were followed up for more than one year. Vitreitis diminished in all patients and visual acuity improved in six patients. The best results were achieved in patients with definitive Lyme borreliosis.

Systemic viral infections and their retinal and choroidal manifestations

Viruses are one of the most common causes of infections involving the posterior segment of the eye. Such infections can occur either on a congenital or an acquired basis, and may affect primarily the retina or the choroid. Congenital cytomegalovirus (CMV) and rubella infections may result in retinitis. CMV retinitis is also the most common cause of acquired viral retinitis, primarily because of the acquired immunodeficiency syndrome (AIDS). Other types of viral retinitis, such as those caused by herpes simplex or herpes zoster, can occur in immunocompromised or immunocompetent individuals. Retinitis or choroiditis caused by viruses such as measles, influenza, Epstein-Barr virus, and Rift Valley fever virus, typically occurs subsequent to an acute viral systemic illness. The systemic and ocular manifestations, as well as the histopathology, laboratory tests, differential diagnoses, and treatment regimens for each of the individual viruses are discussed in detail.

Lyme borreliosis--a review and present situation in Japan

The skin diseases Erythema (chronicum) migrans (ECM, EM), Lymphadenosis benigna cutis (LABC), and Acrodermatitis chronica atrophicans (ACA) have long been described in northern Europe, and dermatologists are very familiar with these manifestations, which have been successfully treated with penicillin for about 40 years without the causative agent being known. Certain neurologic symptoms could be linked to tickbites during the 1920's and later also to EM. In 1977, Steere et al. reported a new form of inflammatory arthritis, mainly in school children in the community of Lyme, Connecticut, U.S.A., which they could also associate with preceding erythema and tickbites. Five years later, Burgdorfer was able to isolate Borrelia spirochetes from Ixodes ticks, which are known to be vectors of Lyme disease as well as of EM and ACA. The following year, Borrelia spirochetes were also isolated from Ixodes ticks and from skin lesions of patients in Sweden and Germany. These findings resulted in a large number of reports of new discoveries related to this infection, which is now known under the names of tick-borne or Lyme borreliosis and, in the U.S., also as Lyme disease or Lyme arthritis. It has proven to be a great imitator disease, mainly through its involvement of the neurological system, and to be far more widespread than previously thought. The full course of the disease is not yet known, however it is clinically, like another spirochetosis, syphilis, divided into early and late stages. Manifestations involve mainly the skin, the joints, the nervous system (Neuroborreliosis), and the heart. Antibiotic treatment is effective, especially in the early stages. Like syphilis, the disease can be self-healing without treatment. People who are exposed to ticks should be aware of the risk of contracting this disease, also in Japan where Ixodes ticks have been shown to be carriers of Borrelia spirochetes. Cases, particularly of EM, but also with neurological symptoms, have already been diagnosed in Hokkaido, Honshu, Shikoku, and Kyushu. As Lyme borreliosis is now proven to exist in Japan, it is beneficial for dermatologists to know about the various presentations of this disease. This paper will briefly summarize the historical background, the clinical stages, the diagnosis, and the treatment of Lyme borreliosis, with a summary of the present situation in Japan.

Lyme disease: neurologic and ophthalmic manifestations

Lyme disease is tick-borne infection which produces early and late manifestations in many organ systems. Prominent symptoms and signs occur in skin, heart, joints and nervous system. Many ocular and neuro-ophthalmic abnormalities recently have been attributed to Lyme disease, but some cases have not been well established as direct sequelae. This review of the contemporary state of knowledge about Lyme disease was undertaken so that more rigorous criteria can be applied in future diagnosis.

The many faces and phases of borreliosis. I. Lyme disease

Lyme disease is increasingly being reported throughout the United States and many parts of the world. Borrelia burgdorferi, the etiologic agent of Lyme disease, is a spirochete that, not unlike the treponema of syphilis, can cause a spectrum of disease from the initial skin lesion, through widely varied symptoms and signs, to chronic neurologic and arthritic disability. The borrelial spirochete and Lyme disease are the subject of this review. A subsequent article will review other definite and possible cutaneous manifestations of borreliosis.

Episcleritis, conjunctivitis, and keratitis as ocular manifestations of Lyme disease

A 35-year-old woman presented with a bilateral palpebral follicular conjunctivitis. Subsequently, she developed a bilateral keratitis and, on a separate occasion, an episcleritis that was associated with a recrudescence of Lyme disease and poor compliance with the antibiotic regimen. Both the keratitis and episcleritis cleared completely after topical corticosteroid therapy and reinstitution of appropriate antibiotic treatment. This report emphasizes the importance of collaboration between internal medicine and ophthalmologic specialists during the long-term management of Lyme disease.

Ocular Lyme disease: case report and review of the literature

Lyme disease is an emerging new spirochaetal disease in which ocular complications may arise. We have seen a 45-year-old woman who developed unilateral endophthalmitis leading to blindness during the course of this disease. Ocular tissue showed the characteristic spirochete. A literature review shows that the commonest ocular manifestation of Lyme disease is a mild conjunctivitis, but other symptoms may include periorbital oedema, oculomotor palsies, uveitis, papilloedema, papillitis, interstitial keratitis, and others. Ophthalmologists treating patients from Lyme disease endemic areas need to be aware of the protean clinical manifestation of this disease.

Orbital myositis with Lyme disease

We examined, treated, and followed up for nine years a 5-year-old girl with active Lyme disease and orbital myositis. Clinically, the patient demonstrated typical symptoms for each of the major stages of Lyme disease, including fever, erythema chronicum migrans, aseptic meningitis, Bell's palsy, and arthritis. She subsequently developed clinical and computed tomographic evidence of orbital myositis. Although orbital myositis is generally considered to be an idiopathic inflammation, our findings suggest that in certain patients it may be a manifestation of Lyme disease.
