The fuse for the syptom can fall into two: one is the systemic lesion which mainly caused by diabetes, high blood pressure and immune system disease and so on. The other is local lesion which mainly caused by retinal vasculitis and retinal choroiditis lesions and other lesions about retina.
I have to confess that I have no home remedy for that, what I can do here is to tell you some basic principles about the treatment.
First of all, you need to have a good rest, avoid fierce exercises and mental stress. Besides, you have to control the level of your blood pressure and blood sugar .
Second, laser therapy, fibrinolytic agents and anti-platelet aggregation are popular in mordern medicine, however, which is not satisfactory in vison recovering.
Thirdly, you may take the sino-western therapy, which I strongly recommend you to do, is implemented by 4 steps:
1.Bleeding period: dispersing blood stasis
2.Blood stasis period: invigorate the circulation of blood
3.Absorption and machine period: promote the elimination of inter eczema
4. Fix the energy and blood by treating both appearance and nature.
Of course, above is just a introduction, you need to do more consultation about the the therapy from traditional herbalist doctor.
Hope that can help.
