There was a lag of dilation in the right pupil in the dark. Facial anhidrosis was present at the right side of the face. Right pupil dilated and upper eyelid ptosis improved with apraclonidine 5g/L application.CONCLUSION: Sympathetic denervation of the eye (Homer's syndrome (HS)) usually presents as a triad of ptosis of upper eyelid, miosis and facial anhydrosis. We present a case of HS after anterior cervical discectomy operation which is an unusual and rare cause of persistant HS.
