My 2 year old baby has this problem, there is redness around her eye iris, she crys and sensible to light. What can it be the problem? What can I do

Light sensitivity. Call your pediatrician and ask for an immediate referral to a pediatric ophthalmologist, not a general ophthalmologist. Your baby could have some serious inflammation or an infection.
Mgt. She should see herPCP and possibly a pediatric Opthalmologist. Light sensitivity may be associated with inflammatory conditions affecting the eye. Gently wash her eyes with sterile saline solution.
