Painful Diplopia as an Initial Presentation of VEXAS Syndrome
NEURO-OPHTHALMOLOGY(2024)
摘要
This is a case report describing an unusual presentation of acute painful diplopia that led to the diagnosis of VEXAS syndrome. VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) syndrome is an adult-onset monogenic auto-inflammatory disease due to somatic UBA1 gene mutation in haematopoietic progenitor cells. Our patient was a 67-year-old diabetic male who presented with painful eye movements associated with diplopia, left periorbital pain and swelling. Imaging revealed an inflammatory process involving multiple intra- and extra-orbital structures. The patient improved initially with a short course of intravenous steroids. However, two months later he re-presented with right facial swelling. Bone marrow biopsy demonstrated UBA1 gene mutation supporting the diagnosis of VEXAS syndrome. This case highlights a unique ocular presentation of VEXAS.
