Optic neuropathy in systemic lupus erythematosus and antiphospholipid syndrome (APS): clinical features, pathogenesis, review of the literature and proposed ophthalmological criteria for APS diagnosis.

Abstract: Optic neuropathy is a well-known ocular manifestation occurring in patients with systemic lupus erythematosus (SLE), and it remains one of the major causes of blindness in these patients. We report data from six SLE patients with optic neuropathy, one of whom was considered to have antiphospholipid syndrome (APS). This patient had monolateral optic neuropathy, whereas the other five SLE patients had bilateral optic nerve disease. We believe that the monolateral occurrence of optic neuropathy in our patient can be considered as a ‘focal’ neurological disease due to a thrombotic event involving the ciliary vasculature. Conversely, bilateral optic nerve damage in SLE could be considered to be a ‘general’ neurological disease due to different immunological mechanisms, such as vasculitis. Additionally, the literature on SLE patients affected by optic neuropathy is reviewed to evaluate the major clinical features, particularly neurological features. In reviewing the literature, it appears that bilateral optic neuropathy in SLE occurs more frequently than monolateral optic neuropathy, and the main neurological manifestation seen in these patients is transverse myelitis, particularly in SLE patients with bilateral optic nerve disease. Finally, we propose a clinico-ophthalmological spectrum of APS and outline the ocular clinical manifestations that can be considered as diagnostic for the syndrome.

Transient visual symptoms in systemic lupus erythematosus and antiphospholipid syndrome.

PURPOSE: To review the potential pathogenic mechanisms of transient visual symptoms (TVS) in the course of systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS), to discuss the most common clinical features associated with the occurrence of TVS, and to explore possible treatment options for these patients. METHODS: The literature regarding the clinical and laboratory characteristics of SLE and APS patients experiencing TVS is reviewed from 1979 onward. A brief review of the wide spectrum of ophthalmologic features occurring in SLE and APS is also provided. RESULTS: Data emerging from the review process point to thromboembolism as the most probable cause of TVS in SLE and APS. Thromboembolisms are likely induced by cardiac valve abnormalities and should be treated with anticoagulant drugs. CONCLUSION: While progress has been made in understanding the association of TVS with SLE and APS, further investigation is needed to clarify this interesting relationship.

Giant cell arteritis: the importance of immediate and appropriate diagnosis and treatment for better prognosis

This article describes the case of a 68-year-old patient suffering from giant cell arteritis (also known as Horton’s arteritis or temporal arteritis). The patient came to our attention due to a large and sudden visual loss caused by the occlusion of major retinal arteries. The patient had neuralgic pain in the face. The next day, for a thorough examination, the patient went to the day hospital with a further worsening of the visual loss which required immediate admission to the ophthalmological ward for hospitalization lasting 10 days. During the observation period it was difficult to make an instant diagnosis due to the absence of clinical signs or diagnostic tests for Horton’s arteritis. Only after the third day of hospitalization, when corticosteroid therapy was undertaken following the appearance of significant systemic symptoms, did the patient begin to show a gradual improvement in overall clinical status. The case highlights the difficulty in making a rapid diagnosis of giant cell arteritis and the efficacy of early steroid therapy in this vascular autoimmune disease that otherwise may result in irreversible functional and debilitating systemic damage.
