Introduction: Vision loss is an ophthalmologic emergency with broad differential requiring prompt medical attention.
Case report: We describe a 55-year-old male presenting to the emergency department (ED) with unilateral, painless visual field deficit with ipsilateral conjunctivitis induced by a presumed foreign body. The patient described a foreign body sensation nine days prior to developing visual changes. In the ED, the patient was diagnosed with a retinal detachment using point-of-care ultrasonography, and emergent ophthalmologic consultation was obtained.
Conclusion: Concurrent retinal detachment and conjunctivitis in a patient is extremely rare. Healthcare providers should be aware that foreign body-induced conjunctivitis could lead to retinal detachment.
