Alternatives to glaucoma surgery are eye drops and pills, according to The Glaucoma Foundation. Eye drops are often the first approach, with oral medications -such as acetazolamide- prescribed less frequently, explains MedicineNet.
Eye drops reduce intraocular pressure by limiting the aqueous fluid made in the eye or increasing the amount of fluid carried away from the organ, MedicineNet explains. Side effects of many eye drops include slow heart rate, low blood pressure, impotence and eye inflammation; in some cases, asthma or emphysema may become worse.
Acetazolamide is a diuretic, which reduces the amount of fluid in the eye, explains MedicineNet. Dizziness, lightheaded-ness and increased urine outflow are some side effects of the prescription.
