Diagnosis Your doctor will go over your medical history and provide a thorough eye check. Several tests may be performed by your provider, including:

• Tonometry is a method of measuring intraocular pressure.
  
• A dilated eye examination and imaging studies are used to screen for optic nerve injury.
• A visual field test is used to look for areas of vision loss.
• Pachymetry is a test that measures the thickness of the cornea.
• Gonioscopy (examination of the drainage angle)

• Prostaglandins. These stimulate the outflow of fluid from your eye, which aids in the reduction of ocular pressure. Latanoprost (Xalatan), travoprost (Travatan Z), tafluprost (Zioptan), bimatoprost (Lumigan), and latanoprostene bunod (Vyzulta) are examples of medications in this category.
• Mild reddening and stinging of the eyes, darkening of the iris, darkening of the pigment of the eyelashes or eyelid skin, and blurred vision are all possible side effects. This medication is only used once a day.
• Beta agonists. These help to relieve eye pressure by reducing fluid production in the eye. Timolol (Betimol, Istalol, Timoptic) and betaxolol (Betoptic S) are two examples.
• Breathing difficulties, decreased heart rate, lower blood pressure, impotence, and weariness are all possible adverse effects. Depending on your situation, this kind of medication may be administered once or twice daily.
• Agonists of the alpha-adrenergic system. These limit the formation of the fluid that circulates inside your eye. They also enhance fluid outflow from your eye. Apraclonidine (Iopidine) and brimonidine (Alphagan P, Qoliana) are two examples.

• Inhibitors of carbonic anhydrase. These medications lessen the amount of fluid produced in your eye. Dorzolamide and brinzolamide (Azopt) are two examples. A metallic taste, frequent urination, and tingling in the fingers and toes are all possible adverse effects. This class of medication is typically administered twice daily, although it can also be prescribed three times each day.
• Inhibitor of Rho kinase. This medication reduces ocular pressure by inhibiting the rho kinase enzymes that cause fluid accumulation. It is marketed as netarsudil (Rhopressa) and is administered once daily. Eye redness and pain are possible side effects.
• Agents that are miotic or cholinergic. These increase the amount of fluid that drains from your eye. Pilocarpine (Isopto Carpine) is one example. Headache, eye pain, smaller pupils, and maybe blurred vision are all possible side effects. Nearsightedness and poor vision. This type of medication is typically administered up to four times per day. These medications are no longer commonly recommended due to the risk of side effects and the requirement for daily administration.
• Because some of the eye drop medication is taken into your bloodstream, you may have some unrelated side effects. Close your eyes for 1 to 2 minutes after applying the drops to reduce absorption. You can also squeeze lightly on the corner of your eyes near your nose for 1 or 2 minutes to shut the tear duct. Wipe any remaining droplets from your eyelid.

• Laser treatment. If you are unable to tolerate eye drops, laser trabeculoplasty (truh-BEK-u-low-plas-tee) is a possibility. It may also be utilised if medical treatment has not halted the progression of your disease. Your eye doctor may also advise you.Before taking eye drops, have laser surgery. It is performed at your eye doctor's office. A tiny laser is used by your eye doctor to improve the drainage of tissue at the angle where the iris and cornea meet. It may take a few weeks for the full impact of this surgery to be felt.
• Surgery for filtering. This is a trabeculectomy (truh-bek-u-LEK-tuh-me) surgical technique. The eye surgeon makes an incision in the white of the eye, often known as the sclera. The operation adds another channel for fluid to exit the eye.
• Tubes for drainage. The eye surgeon puts a tiny tube into your eye to drain extra fluid and decrease eye pressure.
• MIGS stands for minimally invasive glaucoma surgery. Your eye doctor may prescribe recommend a MIGS surgery to reduce your eye pressure. These treatments are less risky and need less immediate postoperative care than trabeculectomy or the use of a drainage device. They are frequently used in conjunction with cataract surgery. There are several MIGS procedures available, and your eye doctor will discuss which one is best for you.
• You'll need to see your eye doctor for follow-up exams after your treatment. Additionally, if your eye pressure continues to rise or other abnormalities occur in your eye, you may need to undergo additional operations.
