My bro's left eyeball (exactly the eyeball esp. the white part, not the skin nearby the eye) is swollen, red n secreting fluid. what may had happened?

Conjunctivitis: By the sound of your description, the red-watery swelling of the white part-the conjunctiva-is irritated. Conjunctivitis may be viral, bacterial, allergic, chemical, or fungal. If symptoms are itching, watery with mild redness, think allergic. If an offending agent got into eye, think chemical or foreign-body related. The other types have a fair amount of yellowish-green discharge and discomfort.

Possible infection: If an eye is swollen, red, and "secreting fluid, " it is very possible that there is an infection or conjunctivitis. If the lid is swollen, pain with eye movement, blurred vision, it is possible that there is an infection in the tissues around the eye or the eye socket. Trauma to the eye can also cause a similar picture. Based on his symptoms as you have described, he should see an eye dr soon.

Another possibility: Besides the answer above... Your brother could simply be experiencing chemosis of the conjunctiva, which is when clear fluid builds up over the white of the eye but under the conjunctiva. It looks like a blister, and it goes away when the underlying allergy is treated. He may need some prescription drops from the ophthalmologist. You can google it and see if the pictures look like his eye...
