Swollen Conjunctiva

The sclera is the white wall of the eye. The conjunctiva overlies the sclera covering it like a blanket. The conjuctiva has blood vessels coursing through it. While it is rare for the sclera to become inflamed (a condition called scleritis causes a deep, boring pain), the conjunctiva may swell and accumulate fluid causing a condition known as "chemosis." Chemosis has no pain, tenderness, or redness. The causes of chemosis include any cause of eye irritation, but thyroid disease or more serious ocular disorders may exist. You are urged to see an ophthalmologist to determine the cause and an appropriate course of treatment for your condition.
