Eye Drops For Glaucoma




Eye drops for glaucoma are the most common way of treatment for glaucoma. Glaucoma is usually controlled by eye drops and sometimes especially in acute glaucoma we can use oral medication which is called acetazolamide which act by decrease the production of aqueous humor. There are many types of them and they either act by reducing the amount of fluid production or increase the amount of fluid drainage.

As any medications, these glaucoma eye drops have side effects which can be tolerated by the many patients but some times due to general health of the patient, some types of eye drops can not be given.

To minimize this side effect you should decrease the amount of eye drops that is absorbed to your blood stream by pressing on the corner or medial side of your eye near the nose after you apply the eye drops, so you can decrease the amount of drug that pass through the nasolacrimal ducts in which it can pass to your blood stream.

When your doctor prescribed more than two eye drops with the same frequency per day, try not to apply both of them at the same time. Make sure to keep at least 10 minutes between each eye drops .

Many people think that they should use eye drops for few days or weeks and then stop them. If the use of eye drops is helpful in controlling glaucoma, the patient should continue using them with regular visits to ophthalmologist who can decide to continue on them or not.
