Anterior ischemic optic neuropathy is a disorder in which the optic nerve becomes damaged due to insufficient blood supply, resulting in vision loss. Xalatan eye drops for treatment of anterior ischemic optic neuropathy may be considered. This eye drop has latanoprost as the active ingredient. The active ingredient is classified as a prostaglandin analogue. It is prescribed in the treatment of increased pressure in the eyeball, by increasing how much fluid is drained from the eye.

Xalatan only has one standard dose. While health care providers may stray from the standard dose, patients should never do so without their health care provider's express permission. The recommended dose is a single drop into one or both eyes, depending on which eye or if both eyes are affected, once a day in the evening. This medication becomes less effective if it is used more often. Patients must thoroughly wash their hands prior to administering this medication.
