Early detection and treatment is the best way to control glaucoma. Glaucoma cannot be cured, but it can be completely controlled. Treatment differs for different types of glaucoma and for the same type of glaucoma at different times in its development. Closed-angle glaucoma is treated primarily with surgery and supplemented by medications, although surgery also includes laser treatment. Closed-angle glaucoma may require only a simple laser treatment in the early stages, but surgery in the middle and late stages; open-angle glaucoma can be treated with medication in the early stages once it is diagnosed, and surgery is needed if the medication cannot control the IOP, and surgery is mostly needed in the late stages; because surgery reduces the pressure more than medication, but there may be some complications related to surgery. Of course, you should follow the doctor’s arrangement.
