Problems with vision?

My mom tells me her vision is getting messed up. In her right eye her direct vision is showing everything small, and her peripheral vision is perfectly fine. Like if she were to look at me directly with left eye closed she sees me really small but everything to the right is perfectly fine. As for her left eye everything is fine. She got it checked by the doctor who said it has to do with high blood pressure. He gave her some eye drops, before she was seeing gray and white spots. Also with her special glasses she got she can see better. Without those she said that her right eye can't see anything in the direct vision, peripheral is still fine. The doctor said it had to do with some blood clot or something forming due to the high blood pressure.

Is there any type of homeopathic medicine which would be helpful for this problem? Lowering blood pressure and helping her eye sight? If not then is there anything else that can be done to help?

Can someone also tell me exactly what the problem here is? The doctor wasn't completely sure either, whether this is actually the problem but I've written the problems she is facing. Thanks for the help in advance I'd really appreciate it if anyone can help.
