My daughter had one steroid injectioin and then oral steroids but in her case it did not work. Although from what I have heared they often do work.
Her H is also around her eye and behind her eye and has affected her vision. Please try not to worry (easier said than done), my daughter is now 15 months old and has also had 3 general anaesthetics (2 for MRI scans) and 1 for an op to debulk some of the H from her eyelid. We live in the UK and they will not remove H's if they can help it, in my daughter's case we approached one of the experts on this site and he said that due to the area removal of an H may be difficult and that laser may be the first thing to do.
The only advise I can give you is to keep going back to you Dr if you are worried or things are not happening quick enough.
