Bruising on side of face and eye

I have a Down Syndrome son who has Keratonocus in both eye's, He had hydrops in the right eye about a year ago, now he has it in his lest eye. One the right side of his face he has bruising on the side of his stemming from his eye. I assume it is from his eye condition but not sure, he's had this for about 5 month's. I brought it up to the Doctor, all he did was give me some cream to put on it thinking it was from his eye's watering-(needless to say, it did nothing). The bruising has seemed to have gotten darker, Has anyone have this problem?
