Hyphema is collection of blood iniside the eye in the anterior chamber of the eye following blunt injury
. The treatment is by bed rest
with head end elevation to facilitate absorption of blood. In the mean time raise in intraocular pressure
by using antiglaucoma medications like alphagon,which you are using.
Now you can wait for 3-4 weeks, if it wont subside by this time and if it is causing complications like secondary glaucoma drainage
of the hyphema is adviced. I advice you to contiune the same treatment as of now and follow up with your ophthalmologist after 3-4 weeks for further plan of treatment.
