A patient with systemic lupus erythematosus (SLE) and lupus retinopathy showed resolution of subretinal edema documented with fluorescein angiography. Subsequently at autopsy, immunofluorescence studies disclosed ocular deposition of immunoglobulins in the vascular layer of choroid capillaries and basement membranes of ciliary processes and bulbar conjunctivas. To our knowledge, these findings represent the first reported documentation of probable immune-complex ocular vasculitis in lupus retinopathy using immunofluorescent techniques, and they support the hypothesis that lupus retinopathy is caused by immune complex deposition as are other manifestations of SLE.

Of 209 patients who fulfilled the A.R.A. criteria for the diagnosis of systemic lupus erythematosus, 43 were selected for study because each had been treated for at least two years with antimalarials, but had not received antimalarials for at least one subsequent year. In each instance, the antimalarial was discontinued solely because of the development of retinopathy. Each year on antimalarials was matched with a subsequent year off antimalarials for each patient. The year immediately following diagnosis and years of pregnancy were excluded. Paired-t test analysis of matched years revealed that general symptoms (fever, fatigue, weight loss) were less common during years on 500 mg chloroquine daily than during years off the drug (p less than 0.05). Skin manifestations were also less frequent during the years on 500 mg chloroquine daily than during the years off (p less than 0.05). No significant steroid sparing effect was found. However, a greater incidence of flare-ups during the matched years off the drug was statistically significant.

Chloroquine and hydroxychloroquine are widely used in diseases of connective tissue, especially in rheumatoid arthritis and systemic lupus erythematosus. However, various side effects are reported in many publications. In general these side effects are less important, e.g. those on the gastrointestinal tract and drug exanthema. Disorders of the haemopoetic system, the central nervous system, and peripheral neuromyopathy are rare. Only few reports exist about fetal damage. In contrary, severe problems result from eye complications such as reversible keratopathy and mostly irreversible retinopathy. If, however, chloroquine is administered, the necessity of exakt dosage and periodic ophthalmologic controls has to be stressed.

Ocular vascular occlusive disease resulting in severe retinopathy and/or post-thrombotic glaucoma has been extensively discussed in patients with lupus anticoagulant and/or anticardiolipin antibodies (LA/aCL). Inadequate circulation plays an important role in the pathogenesis of another ophthalmic entity--the normal tension glaucoma. We studied 22 patients with normal tension glaucoma (group I) and 23 with chronic open-angle glaucoma (group II) and compared them with a control group (n = 25, group III). LA, aCL, the aCL cofactor beta 2-Glycoprotein I, and other haemostatic parameters including factor VIII:C, von Willebrand factor, factors II, V, VII and plasminogen activator inhibitor were measured. Five out of 22 (22.7%) in group I, five out of 23 (21.7%) in group II and three out of 25 (12.0%) in group III had positive LA and/or aCL. These prevalences were not statistically significantly different. beta 2-Glycoprotein I was normal in all groups. No other parameters were significantly different between groups. These findings do not support the contribution of ocular microvascular occlusive disease, due to elevated aCL, in the pathogenesis of glaucomatous damage.

Retinal vascular manifestation is the most common form of ophthalmic involvement in patients with systemic lupus erythematosus (SLE). Most frequently these consist of cotton-wool spots with or without intraretinal hemorrhages. Although rare, a more severe retinal vaso-occlusive disease, termed retinal vasculitis, has been described. We report on a 37-year-old white female with a 13-year follow-up of chronic discoid lupus erythematosus, which suffered massive bilateral visual loss coincident with the systemic exacerbation of her disease (proteinuria, pneumonia, serositis, leucopenia). The diagnosis of SLE was established with reference to the revised ARA-criteria (American Rheumatism Association). Ophthalmoscopy and fluorescein angiography revealed the typical aspect of a SLE-associated vaso-occlusive retinopathy on both eyes with marked ischemia of the macula. Immediate maximal immuno-suppressive therapy, early performed panretinal photocoagulation and subsequent cryoretinopexy did not stop the progression of the disease. Six months after the initial event vascularisations of the disc and rubeosis iridis occurred, but no secondary glaucoma up to date. In this patient, the almost complete absence of characteristic autoantibodies and immunological markers was striking. The correlation with other lupus manifestations, different therapeutic concepts and prognostic factors in SLE-associated retinal vasculitis are discussed.

We have presented a patient with severe clinical SLE but negative serological tests. This diagnostic difficulty, together with a presentation limited to the skin and an initial response to high dose steroids probably lead to a delay in starting immunosuppression. The finding of a retinopathy was important in deciding on therapy. An excellent response to immunosuppression was seen, with full recovery.

The case of a young woman with a rare syndrome of acute encephalopathy followed by deafness and retinopathy developing over 1 year is reported. Unlike previously described similar cases, she had considerable systemic symptoms and signs including polyarthralgia-arthritis, diffuse myalgia, malar rash, livedo reticularis, night sweats, and fatigue suggestive of systemic lupus erythematosus. However, results of most immunological investigations were repeatedly normal, including antinuclear antibodies. Anticardiolipin antibodies were elevated on one occasion. Cyclophosphamide has been the most effective treatment for exacerbations of the disease, which have continued to occur over 6 years. This microangiopathic syndrome more likely relates to an immunologically mediated vasculitis of small blood vessels than to a thromboembolic etiology.

We analyzed ocular findings from two patients (aged 49 and 60 years) with hydroxychloroquine (Plaquenil, Winthrop Pharmaceuticals, Division of Sterling Drug, Inc., New York, New York) retinopathy. Both patients were treated for systemic lupus erythematosus; one patient was treated with 400 to 800 mg of hydroxychloroquine per day (6.1 to 12.2 mg/kg of body weight/day) over a ten-year period. Cumulative doses were 1,788 and 2,920 g, respectively. Neither patient had ever been treated with chloroquine. One patient complained of glare and difficulty in adjusting to changes in illumination, whereas the other was asymptomatic. Both had bilateral visual acuities of 20/25, pericentral scotomata, and increased final dark-adapted rod thresholds in the two retinal areas that were tested. Fullfield electroretinograms were reduced and delayed, and focal cone electroretinography showed abnormal foveal responses as well. Ophthalmoscopy and fluorescein angiography showed a bull's-eye maculopathy in both eyes of one patient and perifoveal depigmentation in both eyes of the other patient. Retinal function remained stable at follow-up examinations 18 to 24 months after the cessation of hydroxychloroquine treatment. These two cases demonstrate that peripheral retinopathy, as well as maculopathy, can develop in patients who are treated with hydroxychloroquine for systemic lupus erythematosus, and that retinal function may remain stable after discontinuation of hydroxychloroquine treatment.

Three patients with systemic lupus erythematosus (SLE) associated with anti-phospholipid antibodies are reported. All three had severe vaso-occlusive disease: the first had an unilateral vaso-occlusive retinopathy, the second an unilateral central retinal venous obstruction, and the third a bilateral ischemic choroidopathy. The association of these occlusive ocular vascular diseases with the presence of the lupus anticoagulant and other associated factors in SLE is discussed.

A patient with a history of hypertension had a combined central retinal artery and vein occlusion in one eye. She had markedly elevated coagulation profiles, especially the partial thromboplastin time, secondary to circulating lupus anticoagulant. Due to the asymmetric involvement, the presence of the anticoagulant, and the lack of any other signs of retinopathy, we believed that the etiology was thrombotic rather than vasculitic. Detection and measurement of the lupus anticoagulant could serve as a marker of disease and in the assessment of disease activity in the follow-up of these patients.
