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.

If you use condoms perfectly every single time you have sex, they’re 98% effective at preventing pregnancy. But people aren’t perfect, so in real life condoms are about 85% effective — that means about 15 out of 100 people who use condoms as their only birth control method will get pregnant each year.
The Epley maneuver is a series of movements, normally carried out on a person by a doctor, to relieve the symptoms of BPPV. Research has found it to be an easy, safe, and effective treatment for the condition in both the long- and short-term. The Epley maneuver is sometimes called the particle repositioning maneuver or the canalith repositioning maneuver. These names are used because the maneuver involves a series of movements that help to reposition crystals in a person's ear that may cause feelings of dizziness. Repositioning the crystals helps to relieve the person's dizziness and nausea.
Tonsillectomy (ton-sih-LEK-tuh-me) is the surgical removal of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. A tonsillectomy was once a common procedure to treat infection and inflammation of the tonsils (tonsillitis). Today, a tonsillectomy is usually performed for sleep-disordered breathing but may still be a treatment when tonsillitis occurs frequently or doesn't respond to other treatments. A tonsillectomy may also be necessary to treat breathing and other problems related to enlarged tonsils and to treat rare diseases of the tonsils.
They are the leaders of the pack when it comes to minimally invasive surgeries. Laparoscopic and robotic. Different techniques with the same benefits.
"There's significantly less blood loss, it's a quicker procedure, quicker recovery, less scarring, less chance for post operative wound complications or infections," says Dr. Darren Miter, laparoscopic surgeon with Lee Memorial Health System.
In a laparoscopic procedure surgeons operate through a series of poke holes, manually inserting thin cutting tools and a camera to provide magnified vision. It's used in a variety of surgical specialties.
"The vast majority of gallbladder surgeries are performed laparoscopically. A single incision in the belly button, one up under the breastbone and either one or two in the right upper side of the belly. Using long skinny instruments and looking up at a TV monitor, remove the gallbladder that way," says Dr. Miter.
While laparoscopic is a hands-on approach, robotic procedures are surgeon-controlled. Working at a console, surgeons direct the robotic arms, which have super-human capabilities and 3D, hi def vision.
"I mean you have to see it to believe it, that's a great tool to have. You got a very good depth perception. Plus the other thing when you're working with your hands it's more intuitive," says Dr. Nagesh Ravipati, colorectal surgeon with Lee Memorial Health System.
The robotic system performs maneuvers the human hand can't.
"Especially if you have to do any suturing, it is so much simpler with the robots because you can just turn around 360 degrees," says Dr. Ravipati.
Robotic surgery is gaining momentum in precise procedures, including the field of cancer.
"The robot is good when you're going to operate on just one field. For rectal surgery you're in one place, it's docked. It gives you the best 3 dimensional vision," says Dr. Ravipati.
Robotic and laparoscopic. Both cutting edge options, with less cutting.

Smallpox disease is a serious, highly contagious, and often life-threatening infection marked by a rash of round pox (blisters) on the face, arms, and legs. It is caused by the Variola virus. The last case of smallpox in the United States was in 1949.
Syringomyelia is a cystic cavitation of the spinal cord associated with Chiari I malformation (70%) or basilar invagination (10%) or tumor. It may be a post-traumatic condition. There are 2 main forms: communicating with the central canal or subarachnoid spaces (Chiari I malformation); non communicating (trauma, tumors).
Antisocial personality disorder (ASPD) is defined by the American Psychiatric Association's Axis II (personality disorders) of the Diagnostic and Statistical Manual (DSM-IV-TR) as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood." Antisocial personality disorder is sometimes wrongly referred to as psychopathy or sociopathy. Currently, neither psychopathy nor sociopathy are valid diagnoses described in the Diagnostic and Statistical Manual of Mental Disorders, and the ICD-10 of the World Health Organization also lacks psychopathy as a diagnostic disorder. Psychopathy is normally seen as a subset of the antisocial personality disorder, but Blair believes that the antisocial personality disorder and psychopathy may be separate conditions altogether.
Liver transplantation is surgery to remove a diseased or injured liver and replace it with a healthy whole liver or a segment of a liver from another person, called a donor. People with either acute or chronic liver failure may need a liver transplant to survive.
This is a technique of correcting knock knee (genu valgum) deformity by surgery. Highligh of the technique is that the bone is not cut, but merely weakened. The advantage is that it provides accuracy to the surgeon, and rapid healing. Once corrected, the bone is held in place with a special plate (Tomofix), which permits walking with crutches the very next day.
