One of the first lines of defense against glaucoma is usually the use of medicated eye drops. Eye drops can either reduce the amount of fluid created in the eye or improve the flow of fluid out of the eye.
For example, certain medicated eye drops contain prostaglandins — drugs that improve the non-conventional flow of fluids out of the eye, thereby reducing intraocular pressure. Other drugs are alpha-adrenergic agonists or beta-blockers, both of which decrease the fluid production in the eye. These eye drops may be prescribed alone or in combination with each other.
Like any medication, medicated eye drops are not prescribed to individuals that have certain medical conditions or health concerns. For some individuals, eye drops placed in the eye could be absorbed by the blood vessels in the nasal mucosa and may affect heart rate and breathing. In rare cases, some eye drops can compromise health and exacerbate certain conditions like asthma. For this reason, all candidates are carefully evaluated and their detailed medical history is recorded before the doctor prescribes medicated eye drops.
