Abstract

Introduction: Retinal detachment (RD) is a vision-threatening emergency characterized by the separation of the neurosensory retina from the underlying choroid. Classic symptoms include the sudden onset of floaters, photopsia, and a curtain-like visual field defect.
Case report: We report a rare case of RD, in a young patient with multiple sclerosis, presenting with isolated symptoms of blurred vision with the help of point-of-care ocular ultrasound (POCUS). The patient lacked traditional risk factors for RD and was on immunosuppressants which likely masked typical symptoms.
Conclusion: This case highlights the diagnostic challenges of RD in immunosuppressed patients with atypical presentations. Emergency physicians should maintain a high index of suspicion for RD, even in the absence of classic symptoms, and utilize POCUS for timely diagnosis and referral.
