Herbal formula plus eye injections: a new hope for blocked retinal veins?

This trial tests whether adding an oral Chinese herbal formula called Tongluo Huayu to standard care (eye injections and laser therapy) can improve vision and reduce retinal swelling in people with retinal vein occlusion. Eighty participants will receive either standard treatment alone or standard treatment plus the herbal formula for one month. Researchers will track changes in retinal thickness and vision over six months to see if the combination works better than standard care alone.
