What can i do if i've already lost some vision from glaucoma?

Good followup: The key to slowing down vision loss from glaucoma is having regular testing with a glaucoma care specialist and using a therapy that lowers eye pressure enough to preserve vision while avoiding side effects. If it's a medication, then proper usage and compliance/persistence are critical.

Stop losing anymore: Unfortunately, you can't get back what you've lost already. However, even with advanced glaucoma, most people don't have any symptoms. Therefore its very important that you treat the glaucoma so you don't lose anymore vision.

Treatment, checkups: It is really important that you establish a relationship with an eyemd to prevent further damage and get checked regularly. Treatment may vary depending on what you have already tried to control it. Do not waste another day!
