Glaucoma, a group of eye diseases that can result in optic nerve damage and irreversible blindness, is one of the most vexing issues in healthcare, affecting 60–80 million people globally.
The world's #1 cause of irreversible blindness
What Causes Glaucoma?
The exact cause of optic nerve damage from glaucoma is not fully understood, but high eye pressure is most often associated with the disease. High intraocular pressure (IOP) left untreated may result in irreversible optic nerve damage that can ultimately lead to blindness.
A healthy eye drains continuously
and without obstruction
Blockages in the natural drainage system can
develop, increasing intraocular pressure
A life-long eye disease called Glaucoma
develops, which can cause
irreversible vision loss
The Varying Types of Glaucoma
The two main types of glaucoma are open-angle glaucoma and angle-closure glaucoma. Each is most commonly marked by an increase of IOP inside the eye.
Sight Sciences surgical systems are intended to lower pressure in patients suffering from open-angle glaucoma, the most common form of glaucoma that accounts for 90% of all cases*.
In open-angle glaucoma, the drainage angle formed by the cornea and the iris remains open, but the eye’s drainage canal remains blocked, resulting in a slow increase in eye pressure.
Patients may not notice they have lost vision until the disease has progressed significantly.

Current Treatment Options
There is no cure for glaucoma, but there are several treatments intended to reduce the intraocular pressure associated with the disease. The cost and burden of such treatment methods, which involve daily, costly, and sometimes painful eye drops or highly invasive surgery, have driven the development of novel, less invasive surgical approaches.
Glaucoma treatment can vary as the disease progresses. More recently, less invasive glaucoma devices have been approved that can be delivered through only a single, sutureless corneal incision and can slow the progression of disease, delay the need for a more invasive surgery, and often reduce the medication burden for patients.
