1year3month old boy had a viral pink eye 6month back.cured in 2 days.came back today again after 6 months.is it ok?or any other possibility

OK: "Pink eye," conjunctivitis, is a common condition usually without serious consequence.

Pink Eye: First you have to make sure it is Pink eye, there are a lot of other conditions that looks like a simple conjunctivitis. Usually it is a simple infection and does not cause any problems or chronic conditions, when it is recurrent you need to make sure it is not dust allergy, or sun sensitivity to name a few so definitely see your doctor if its coming back, To Good Health Dr. Parisa
