A 43-year-old man developed central serous choroidoretinopathy in his left eye following dacryocystorhinostomy operation on the same side. He was using xylometazoline nasal drops in his left nostril. Action of xylometazoline or the stress related to the operation or the effect of both factors played the role in the causation of this ocular condition. Omission of nasal drops or relief from stress resulted in full recovery of vision and complete resolution of symptoms within one month.
