Abcess of Eye photos

This is Doodlebug. Initially, there was some swelling in the left cheek area and the eye looks watery and 3rd eyelid visible:

Here's the view from the front. You can see the eye looks watery and there's a red area at back corner of eye:

Was there something wrong with is eye to cause abscess? Looks kinda similar to my Beeker's problem and so far antibiotcs/lancing/pain meds are working. I am worried about his eye and problems down the road.
