A Case of Eosinophilic Chronic Rhinosinusitis Associated with Choroidal Folds and Ocular Motility Disorder

Abstract

We report a case of eosinophilic chronic rhinosinusitis (ECRS) associated with choroidal folds and ocular motility disorder. A 50-year-old male with rhinosinusitis and bronchial asthma presented with anorthopia of the lower visual field and ocular motility disorder of the left eye. Dilated fundus examination and optical coherence tomography (OCT) revealed wavy choroidal folds in the upper retina. An emergent computed tomography (CT) showed sinusitis, a partial defect of the superior wall of the orbit on the left side, and deformation of the left eye. Based on the clinical findings, the patient was diagnosed with sinusitis complicated by ocular motility disorder. Endoscopic sinus surgery (ESS) was performed. A histopathological examination of the excised polyps showed extensive eosinophil invasion. According to the clinical findings of the nasal polyps, CT images, and peripheral blood tests, he was diagnosed as ECRS. One month after ESS, both ocular movement and anorthopia were improved. The choroidal folds observed using OCT disappeared 2 months after ESS. Although ECRS is rarely associated with ocular complications, bone involvement in sinusitis may result in deformation of the eyeball leading to choroidal folds and ocular motility disorder.
