Visible subject assessments are carried out to find out the extent of peripheral imaginative and prescient loss, which is a trademark of glaucoma.
As soon as recognized, the purpose of therapy is to scale back intraocular stress and stop additional optic nerve harm. Early therapy can work to cease the harm and shield your imaginative and prescient. Remedy choices for glaucoma embrace eye drops, oral drugs, laser remedy, and surgical procedure.
