I suspect you may have diabetic related bleeding or perhaps a branch or central retinal vein occlusion - just guessing. The laser is fairly easily performed and generally safe and without it you coulf face much worse loss of vision. Make sure you are seeing a retinal specialist ophthalmologist.

Dear mila46,
It is difficult from your description to determine what type and exactly where the bleeding is. I would recommend that you see your eyeMD and ask him/her this question. Become informed about your condition.
