General examination of the eye was carried out in 22 patients with systemic lupus erythematosus (SLE) and in 10 with scleroderma. 3 of the SLE and 2 of the scleroderma patients had keratoconjunctivitis sicca. Fluorescein angiography showed abnormalities of the retinal vasculature in one of a subgroup of 12 SLE patients and one of 10 scleroderma patients. None of the 12 SLE patients had abnormalities of the choroidal vasculature, while 5 of the 10 scleroderma patients had patchy areas of nonperfusion of the choroidal capillary bed.

Four patients with systemic lupus erythematosus (SLE) developed an unusual form of occlusive retinal arterial disease. The most prominent clinical features of this disorder were deposition of yellow-white material in retinal arterial walls and evidence of multifocal retinal arterial occlusion. Fluorescein angiographic findings included nonperfusion of the obstructed arteries and the retinal capillary beds fed by them, and fluorescein leakage at the sites of involvement of the retinal arteries. This ocular complication of SLE is presumably a manifestation of the widespread systemic vascular problems seen in this disorder. It may be more common in patients with lupus involving the CNS.

Interstitial immune complex nephritis in patients with systemic lupus erythematosus (SLE). Renal tissues from 45 patients with SLE nephritis, 34 patients with idiopathic membranous nephropathy (IMN) and 77 patients with minimal glomerular disease (MGD) were studied by light, immunofluorescence and electron microscopy. Interstitial nephritis characterized by focal or diffuse infiltration of inflammatory cells, tubular damage and interstitial fibrosis was observed in 66% of SLE patients. Fluorescein-conjugated antibodies to immunoglobulins or complement or both were bound to peritubular capillaries, interstitium and tubular basement membranes (TBM) in 53% of patients with a granular pattern corresponding to opaque deposits seen by light or electron microscopy or both. Antibodies reactive with thymidine or cytosine or both were bound to interstitial structures in 19% of patients tested and showed the same granular distribution. Interstitial cellular infiltration was rare and deposits of immunoglobulins and complement were rare or absent in IMN and MGD, whereas deposits of DNA products were never observed. The findings are consistent with the interpretation that in patients with SLE nephritis immune deposits, presumably containing DNA-anti-DNA complexes, localize in peritublular capillaries, TBM and interstitum, thereby producing an inflammatory reaction which contributes to development and evolution of renal diseases.

The lupus of NZB/NZW F1 female mice is associated with immune complex glomerulonephritis and premature death. Cyclophosphamide and 15(S)-15 methyl PGE1 therapy halt disease progression. Fluorescein conjugated antibodies were utilized to label specific leukocytes and the subsets were quantitated using a Fluorescence Activated Cell Sorter. Normal outbred CD-1 female mice showed a decrease in absolute T and B cell numbers with age, but the ratio of T and B cells remained essentially constant through 9 months of age. By contrast the NZB/W female mice showed decreased numbers of total lymphocytes relative to CD-1 controls at all ages. Moreover relative to CD-1s, there was a far greater decrease in T cell numbers (7 x for NZB/W versus 2 x for CD-1) and B cell numbers failed to decrease with age. The characteristic decline in T lymphocyte numbers and relative increase in B cell numbers in NZB/W mice were corrected with cyclophosphamide and PGE1 therapy. However, there was no selective modification of T cell subsets (L3T4+ or Ly2+) with therapy. Our investigation suggests correction of the abnormal T/B cell ratio may be a useful marker of therapeutic activity in NZB/W mice.

We measured levels of complement anaphylatoxin split products, C3a and C5a, in the circulation of patients with systemic lupus erythematosus (SLE). In 23 SLE patients who were followed serially, the mean C3a value was 179 ng/ml during stable disease and 550 ng/ml during a disease flare. In 10 patients, C3a levels predicted disease activity, with the C3a value rising from a mean of 183 ng/ml at a time of stable disease to a mean of 242 ng/ml 1-2 months prior to a clinical exacerbation of disease. The mean C3a level in 5 patients with acute dysfunction of the central nervous system (CNS) was 1,297 ng/ml, which is significantly higher than that observed in patients with active disease but without CNS involvement (P less than 0.01). C5a levels were also significantly elevated in 4 patients with acute CNS disease. Pathologic specimens from 2 patients who died during an acute lupus flare revealed neutrophils occluding the cerebral and intestinal vessels. Fluorescein angiography in a patient with CNS lupus revealed vasoocclusive retinopathy. In 5 of 7 SLE patients who were pregnant, C3a levels were elevated, with a group mean value of 310 ng/ml. There was a negative correlation (r = -0.59) between C3a and C3 levels in pregnant patients with SLE, and this finding is consistent with complement activation as the cause of decreasing C3 levels. We suggest that serial measurements of C3a can predict flares of disease in lupus patients and can demonstrate complement activation during pregnancy in women with SLE. In addition, release of C3a and C5a (mediators of inflammation) into the circulation may elicit vascular injury, particularly in patients with lupus cerebritis.

We experienced 2 females with systemic lupus erythematosus (SLE) who developed serous retinal detachment in the posterior pole of both eyes in its active phase. Fluorescein angiography showed multifocal pigment epithelial damages with fluorescein leakage into the subretinal space. However, retinal hemorrhages or cotton-wool spots typical of SLE were not observed in their courses.

We report two cases of antiphospholipid antibody syndrome with elevated anti-beta 2-glycoprotein I antibodies. Patient 1 had systemic lupus erythematosus (SLE) and was treated with an oral corticosteroid and aspirin. There were foci of sheathed retinal arterioles appearing as white lines in the fundus of both eyes. The sheathed arterioles of the peripheral fundus of the right eye were completely or incompletely occluded. Recanalization occurred during a 10 month follow-up. Patient 2 had hypertension and multiple brain infarction but no association with collagen diseases. Major retinal arterioles showed sheathing. Fluorescein angiography demonstrated progressive occlusion or stenosis of these major arterioles with extensive insufficiency of regional capillary bed circulation. Retinal photocoagulation was applied to both eyes which developed neovascularization. Vitrectomy was performed in the left eye with recurrent vitreous hemorrhage. Antiphospholipid antibody syndrome should be considered in cases of sheathed or white retinal arterioles.

We report a case of branch retinal artery occlusion (BRAO) in a patient with iron-deficiency anemia. Various ophthalmological and laboratory studies were performed. A 32-year-old man had a sudden decrease of vision in his left eye to counting fingers at 30 cm two days ago. The left fundus showed a cherry-red spot and milky-white edema, except for the upper temporal region of the macula, and an optic disc malformation. Fluorescein angiography revealed leakage from the disc and a slightly delayed filling time in the left eye but an arterial filling defect was not noted. The differential diagnosis in this young patient includes polycythemia, hypercoagulopathy, coagulation abnormalities, trauma, hypertension, and autoimmune diseases such as systemic lupus erythematosus. Laboratory examinations revealed no abnormalities except for iron-deficiency anemia. The patient was treated with stellate ganglion block, hyperbaric oxygen, and ferrous sulfate. His visual acuity never recovered to better than 0.08. He had a coincidental rectal carcinoid and the tumor was excised surgically. No metastasis was observed. BRAO can be a complication of anemic retinopathy and can lead to severe visual loss without early medication.

We report a case of bilateral choroidopathy in a 35-year-old woman with systemic lupus erythematosus (SLE) diagnosed 3 years previously, and treated with hydroxychloroquine and steroids that ceased 6 months before ocular signs. She complained about rapid bilateral blurred vision with a severe loss of visual acuity. Fluorescein angiography found multiple leakage points in the posterior pole of the pigment epithelium. Ocular coherence tomography (OCT) and fundoscopy showed bilateral retinal detachments. Lupus choroidopathy was diagnosed and high steroids were given intravenously and allowed a rapid improvement. Visual acuity, fundoscopy, retinal angiography and OCT were normalized at 2 months. Choroidopathy is rarely reported in lupus and only about 30 patients are found in the literature.

A 22-year-old female with history of systemic lupus erythematosus (SLE) was referred for evaluation of decreased visual acuity in her right eye. Her best-corrected visual acuity (BCVA) at the time of presentation was 20/160. Widespread cotton wool spots and macular edema were seen on biomicroscopy. Fluorescein angiography (FA) revealed retinal arterial and venous obstruction with capillary nonperfusion at the superotemporal retina. Antiphospholipid syndrome (APS) was diagnosed based on positive lupus anti-coagulant and ocular manifestations. Scattered laser photocoagulation was applied at the nonperfusion area but the visual acuity continued to deteriorate due to macular edema. Intravitreal bevacizumab (IVB) was administered for macular edema. One day after IVB, the BCVA decreased to count fingers. FA revealed extended non-perfusion from the superotemporal area to the posterior pole. Use of intravitreal bevacizumab for macular edema secondary to SLE or APS should be considered carefully and patients monitored closely for vascular complications.
