Glaucoma

 

Glaucoma is a leading cause of blindness in the United States , especially for older people. But loss of sight from glaucoma is preventable if you get treatment early enough.

 
Glaucoma is a disease of the optic nerve. The optic nerve carries the images we see to the brain. Many people know that glaucoma has something to do with pressure inside the eye. The higher the pressure inside the eye, the greater the chance of damage to the optic nerve.
The optic nerve is like an electric cable containing a huge number of wires. Glaucoma can damage nerve fibers, causing blind spots to develop.
 
Often people don't notice these blind areas until much optic nerve damage has already occurred. If the entire nerve is destroyed, blindness results. Early detection and treatment by your ophthalmologist are the keys to preventing optic nerve damage and blindness from glaucoma.
 


Aquaflow

The AquaFlow is a tiny piece of collagen that is implanted in a space carefully prepared by your doctor under the white of the eye. It maintains the space created by your doctor to increase fluid outflow in order to reduce pressure within the eye. The AquaFlow Collagen Glaucoma Drainage Device when used with a non-penetrating deep sclerectomy procedure has been proven to significantly lower intraocular pressure while minimizing both the complications often associated with penetrating procedures and reducing the need for medications.

The procedure to implant the AquaFlow device requires approximately 30 – 45 minutes from start to finish. In most cases, the patient is made comfortable with a mild sedative while anesthetics are used to numb the eye.

Trabeculectomy

Trabeculectomy is a glaucoma surgery that creates an alternative drainage pathway for fluid in the eye, thereby lowering the eye pressure.

The Procedure

Surgery is done in an outpatient operating room with a local anesthetic injection. The conjunctiva, the mucous membrane overlying the white part of the eye, is incised and dissected off the eye. A small trapdoor flap is then created in the sclera, the thicker white part of the eye underlying the conjunctiva. Beneath this flap a tiny hole is created to allow fluid to flow out of the eye. The trapdoor flap is then gently stitched down so that the fluid coming out of the eye is controlled. The conjunctiva is subsequently stitched back in place in a watertight fashion so the fluid from the eye collects beneath it, forming a small elevation called a bleb.

Plasma Blade

Fugo Blade/Plasma Blade

Highly precise instruments like the Fugo Blade are especially useful in cataract surgery and in surgical treatment of glaucoma. Having laser-like interaction with tissue, the Fugo blade cuts with a 100-micron filament that heats to 450°C. The heat is extremely focused so there is minimal damage to surrounding tissue.

The Fugo Blade Procedures

Transciliary Filtration for Glaucoma . The Fugo Blade creates a small pore through the sclera and ciliary body without true cutting, using plasma energy surrounding its filament. The tissue bonds separate, allowing a nearly resistance-free incision and minimal bleeding. The incision acts like a bypass to help the eye’s natural fluid drain more easily and thereby lower eye pressure.
