Any connection between food allergies and scleritis?

No: Food allergy does not cause scleritis.

No: The sclera is not affected by allergy. The conjunctivae, the translucent tissue that covers the sclera. Is commonly affected by allergy. In food allergic patients a drop of food to which the patient is allergic dropped into the eye can cause chemosis that is marked swelling of the conjunctivitis. I've seen this when milk-allergic patients get a drop of milk in the eye. (photo of chemosis).
