Macular capillary recovery in systemic lupus erythematosus complicated by Kikuchi-Fujimoto disease.

PURPOSE: Few case reports have described vaso-occlusive retinopathy in systemic lupus erythematosus (SLE) using optical coherence tomography (OCT) angiography. Here we report the clinical features of a patient with SLE, complicated by Kikuchi-Fujimoto disease, who developed vaso-occlusive retinopathy. We then describe the subsequent recovery of the macular capillaries as assessed by OCT angiography.

CASE: A 16-year-old male was referred to us with fever, a 1-month history of violaceous red papules and erythematous plaques on his face and a painful nodule in his right neck. We diagnosed him with SLE complicated by Kikuchi-Fujimoto disease through physiological assessment and histology from his neck lymph node and chin skin. Systemic steroids were prescribed as treatment. After remission, his fever and cervical lymph node swelling with pain recurred and he developed blurred inferior vision in his left eye. His best-corrected visual acuities were 1.0 and 0.1 in the right and left eyes, respectively. Extensive cotton wool spots were observed in the right fundus, and retinal capillary occlusions were detected by OCT angiography of the left eye. We diagnosed this case as vaso-occlusive retinopathy with SLE and increased immunosuppressive treatment together with anticoagulation therapy. Macular capillaries, observed by OCT angiography, gradually recovered function following assessment at 7 and 16 months post-onset of the vaso-occlusive retinopathy.

CONCLUSIONS

We reported a 1½-year course of vaso-occlusive retinopathy in a patient with SLE complicated by Kikuchi-Fujimoto disease. Occlusion of the retinal vasculature and the subsequent recovery of circulation are clearly observed by OCT angiography.
