The World Health Organization considers glaucoma one of the primary causes of irreversible vision loss and blindness. Yet, according to a national survey commissioned by Allergan in collaboration with the Glaucoma Research Foundation, approximately 40% consider glaucoma to be somewhat or not very serious.
In glaucoma, vision loss due to elevated IOP in the eye is irreversible and often worsens over time. Uncontrolled, increased and changing IOP causes damage to the optic nerve and loss of vision.
Current treatments to lower IOP and preserve sight include eye drops, laser trabeculoplasty, minimally invasive glaucoma surgery and incisional surgery. In open-angle glaucoma eye drops are the standard-of-care treatment, but not everyone takes their medicine or does so correctly. One reason for this is that up to 59% of people using drops have ocular surface disease.
