Eye Case 1::
Blepharitis?
16 month old kid (can't talk) comes in with an inflammed upper eye-lid (left side only).  I am thinking its some type of infection (the conjunctiva is not red or has any type of discharge).  After close inspection/plapation, we notice a small nodule (not a chalazion) in the middle of the inflammation.

DX:  insect bite (wasp)

TX: corticosteroid cream

Eye Case 2::
5 y.o. girl comes in with some inflammation and erythema around both eyes.  Yesterday, she was in the pool and there was grass being cut nearby.  PE reveals no purulent discharge, no redness in conjunctiva, its very itchy around the eyes.

DX:  allergic reaction
