Trabeculectomy, also called Filtration Surgery, is a surgical procedure performed for treatment of glaucoma. The treatment involves removing part of the trabecular meshwork and creating a new escape route for the aqueous humor. When successful, it allows the aqueous fluid to drain from the eye into an area underneath the conjunctiva where it is subsequently absorbed by the body's circulatory system or filtered into tears.
In this procedure:
- A conjunctival pocket is created and maybe treated with Mitomycin or other antimetabolites for a few minutes. These drugs are used to prevent scarring of the operation site. Scarring, if occurs, may clog the new drainage canal, and is therefore the major reason the procedure may fail.
- A half thickness flap is then made in the sclera and is dissected all the way to the clear cornea.
- A block of scleral tissue including part of the trabecular meshwork and Schlemm's canal is then removed to make a hole into the anterior chamber of the eye.
- As the iris may plug up this hole from the inside, a piece of the iris maybe removed at this time. This is called iridectomy.
- The scleral flap is then sutured loosely back in place. These sutures can be released gradually during a couple of weeks after surgery. This allows adjustment of the aqueous flow in order to achieve target pressure and to avoid the complication of having a too low intraocular pressure.
- The conjunctiva is sewn back in place to cover the area.
After surgery, aqueous humor drains into a filtering area called a "bleb" under the conjunctiva. Since the surgery is usually performed near the top of the eye, the bleb can easily be concealed behind the upper eyelid.

Rhumatic fever has almost been eraicated in the developed world, however it remains prevelent in many under developed countries and causes devastating damage to heart valves. Up till recently valve replacement was the treatment of choice. The long term results and sequelae of valve replacement are...
common knowledge. Mitral and tricuspid valve replacement results are on the whole far worse than for example Aortic valve. Mitral valve replacement should be the last resort and patients with very severe valvular and sub valvular mitral disease can nowadays be helped by mitral valve repair. NO MITRAL OR TRICUSPID VALVE SHOULD BE REPLACED IF IT CAN BE REPAIRED
Prostate Cancer spreads in 3 ways. First is spreads by local growth. Second it spreads through the lymphatic system, and lastly, it spreads through the blood stream. Dr. Patrick Swift, a radiation oncologist, discusses how prostate cancer spreads.
