Cyclocryotherapy for Endstage Glaucoma

By Richard P. Wilson

A Brief Explanation of Glaucoma

Glaucoma is a general term used to describe a group of diseases of the eye, all of which have pressure within the eye greater than the eye can tolerate and still remain healthy. Where does this pressure come from? In the front of the eye, there is a watery fluid called aqueous which keeps the eyeball firm and its contents clear. This aqueous fluid is produced by a part of the eye called ...

Aqueous Shunts from the Anterior Chamber of the Eye to the Posterior Reservior

By Richard P. Wilson

Glaucoma is a disease in which the drainage mechanism of the eye has become blocked. Since an eye normally produces a watery fluid called aqueous throughout life, this fluid has nowhere to go and backs up. This causes a build-up of pressure within the eye which injures the optic nerve. The safest and simplest type of surgery to reduce intraocular pressure is a trabeculectomy, a procedure which makes a flap valve on top of the eye. This ...

Trabeculectomy

By Richard P. Wilson

One way to relieve the dangerously high pressure in an eye with glaucoma is to make a new drain in the eye, a bypass for the blocked natural drain. This is called a trabeculectomy and is a surgical procedure. It takes the form of a “flap valve” on the top of the eye, the white part of the eye hidden under the upper eyelid. The eye pressure is relieved because fluid can now drain through the new ...

Nd: YAG Cyclophotocoagulation Therapy for Difficult Glaucoma

By Richard P. Wilson, M.D.

A clear watery fluid called aqueous is being produced by the ciliary body of the eye at all times. This fluid circulates through the front of the eye and exits through the trabecular meshwork, or drain of the eye, into the bloodstream. The ciliary body is a band of tissue just behind where the clear cornea meets the white of the eye. At this point, a laser can be focused to burn and destroy part of ...
