Tests and diagnosis

By Mayo Clinic staff

Your doctor may take a sample of eye secretions from the conjunctiva for laboratory analysis to determine which form of infection you have and how best to treat it.

If you have a young infant with recurrent pink eye or persistent eye tearing, your child may have a blocked tear duct. Your child's pediatrician may closely monitor the situation to see if the tear duct opens on its own, or you may be referred to an eye specialist (ophthalmologist) for further evaluation and treatment.
