This individual is not contagious.  But he does have a serious case of Parinaud's cat scratch fever.  We shared this photo with you to help you understand not all cases of red eyes are due to dryness, "pink eye," or simple common bacterial infections.  

If your eye is red for more than a day, please give us a call to schedule an appointment.  If you have loss of vision, pain or light sensitivity, especially if you are a contact lens wearer, it could be a vision threatening problem.  This should be evaluated immediately by an optometrist or ophthalmologist, rather than your primary care physician.
