Subretinal fluid in a patient with systemic lupus erythematosus.

A 28-year-old male patient presented to the outpatient department with visual disturbance in both eyes. The patient had a history of stage IV lupus nephritis that was diagnosed at the age of 14 years and had undergone hemodialysis at the age of 23 years. After he started hemodialysis, the systemic condition was well controlled, and systemic steroids were not used. His best-corrected visual acuity (BCVA) was 20/200 in the right eye and 20/100 in the left eye. Funduscopic examination revealed shallow subretinal fluid (SRF) and serous retinal detachment in both eyes. The first impression of this patient was central serous chorioretinopathy. However, the late phase of fluorescein angiography (FA) demonstrated multiple subretinal leakages, and the late phase of indocyanine green angiography showed choroidal vascular engorgement and multiple hyperfluorescent plaques in both eyes. Systemic lupus erythematosus showed moderate activity according to the results of the systemic evaluation. Based on the clinical examination, lupus choroidopathy was suspected in both eyes. Half-fluence photodynamic therapy (PDT) was administered to both eyes rather than systemic steroids because the patient was systemically stable. Three months after PDT, no SRF was observed in either eye. In addition, multiple subretinal leakages on FA were reduced compared to those before treatment. There was no recurrence of SRF for 4 years after PDT, and the final BCVA was 20/70 in the right eye and 20/40 in the left eye. During this time, numerous hypoautofluorescence spots appeared adjacent to the major retinal vessels in fundus autofluorescence.
