Abstract Purpose:We report choroidal blood flow changes measured using by Laser Speckle Flowgraphy(LSFG) in a patient who developed serous retinal detachment(SRD) during treatment for protein-losing enteropathy(PLE) associated with systemic lupus erythematosus(SLE).

Case:A 61-year-old female presented with bilateral blurred vision during treatment for PLE-associated with SLE. Initial examination revealed best-corrected visual acuity of 0.4 and 0.6 in the right and left eyes, respectively, with bilateral SRD and macular edema. Optical coherence tomography revealed significant choroidal thickening(right eye:571 μm, left eye:805 μm). LSFG analysis identified reduced choroidal circulation in both macular regions, with mean blur rates of 5.2 arbitrary units(AU) in the right eye and 4.5 AU in the left eye, characterized by cool-toned color mapping. Laboratory findings indicated hypoalbuminemia secondary to PLE. Following six months of systemic corticosteroid therapy, improvement was observed in the serum albumin level, corresponding with reduced choroidal thickness(right eye:527 μm, left eye:578 μm) and increased macular choroidal blood flow(right eye:8.2 AU, left eye:7.7 AU). Best-corrected visual acuity improved to 1.2 and 0.8 in the right and left eyes, respectively. The resolution of SRD and macular edema appeared to result from normalized choroidal circulation, which was attributed to improved plasma oncotic pressure following correction of hypoalbuminemia.

Conclusion:In this case of PLE-associated SRD, improvement of hypoalbuminemia through corticosteroid therapy led to normalization of choroidal circulation, resulting in resolution of SRD. LSFG demonstrated potential utility in evaluating choroidal hemodynamics and monitoring therapeutic response in this condition.
