Beta Blockers work by decreasing production of intraocular fluid. They are available in generic form, and therefore are relatively inexpensive. Systemic side effects can be minimized by closing the eyes following application or using a technique, called punctal occlusion, that prevents the drug from entering the tear drainage duct and systemic circulation.
Side effects can include low blood pressure, reduced pulse rate, and fatigue. Beta blockers can also cause a shortness of breath in people who have a history of asthma or other respiratory disorders. Additionally, beta blockers can change cardiac activity by decreasing the amount of blood the heart pumps out, which may reduce the pulse rate and/or slow down the heart's response rate during exercise.
