    Abstract:
    PURPOSE: Purtscher-like retinopathy is a rare and vision-threatening eye disease, which is usually associated with acute pancreatitis, autoimmune diseases, and renal failure. We here reported a case of Purtscher-like retinopathy after dupilumab treatment in atopic dermatitis. CASE REPORT: A 48-year-old woman with a history of severe atopic dermatitis developed ocular manifestations after second exposure to dupilumab. Best-corrected visual acuity (BCVA) was count fingers at 2 feet in the right eye and 20/133 in the left eye when she referred to our hospital. Fundus examination demonstrated bilateral serous macular off, thickening of papillomacular bundle, intraretinal hemorrhage, cotton-wool spots and Purtscher flecken surrounding the optic disc. Optical coherence tomography (OCT) angiography showed flow void in the superficial and deep capillary plexuses. And early hypofluorescence corresponding to grayish-white retinal thickening was observed in fundus fluorescein angiography. Laboratory tests revealed hypereosinophilia after symptoms appeared. A diagnosis of Purtscher-like retinopathy was made, which may associate with dupilumab. The patient accepted the treatment with glucocorticoids. At six months follow up, BCVA was 20/40 in the right eye and 20/25 in the left eye. CONCLUSION: The Purtscher-like retinopathy we report may be the adverse event of dupilumab. Rare adverse reactions to biologics deserve the attention of ophthalmologists.
