Glaucoma Diagnosis And Treatment

Dr. Burns provide Glaucoma treatment in Louisville Kentucky.

What is Glaucoma?

Glaucoma is a group of eye diseases that gradually damage the optic nerve, eventually robbing a person of vision. In order to prevent blindness, early detect is crucial. People afflicted with glaucoma often have no noticeable early symptoms, and by the time they notice a change in their vision, it may be too late to save their sight. Glaucoma is not curable, but it can be controlled. It was once thought that intraocular pressure (IOP) was the primary cause of optic nerve damage, but it has since been found that other risk factors can play a role in vision loss, even when people have normal IOP. This is one of the reasons why Dr. Burns uses a state of the art Optical Coherence Tonography (OCT) for early glaucoma detection and diagnosis.

How does glaucoma affect my vision?

Aqueous humor is a clear fluid that fills the front of your eye. It is important in helping to keep the eye healthy. Also, the aqueous fluid provides pressure to maintain the shape of the eye, like the air in a balloon. This pressure is called intraocular pressure or IOP.

In a healthy eye, the aqueous fluid flows in and out of the natural drainage system. With most types of glaucoma, this system does not work properly. The fluid inside the eye cannot drain. As a result, the pressure or IOP inside the eye increases. This pressure affects the optic nerve, resulting in vision loss.

Diagnosis of Glaucoma: OCT Analyzer

Rather than measure intraocular pressure, the OCT  analyzer uses a laser to quickly and painlessly measure the thickness of the optic nerve fibers on the retinal surface, just before they come together to form the optic nerve. The OCT produces a color-coded picture of the nerve fiber layer, which allows Dr. Burns to diagnose glaucoma at the earliest possible stages.

David A.
“Dr. Burns gave excellent service to my wife. This is a practice that is professionally run, friendly and patient-centered. My wife had glaucoma and advanced cataracts in both eyes which had been misdiagnosed by other eye doctors. When we first visited Dr. Burns practice, my wife had lost 85 % of her sight in one eye and 50% in the other eye. After the surgeries, we received calls from his practice to check on how she was doing. The post-surgery follow-ups were also professionally handled. The end result was a remarkably improved eyesight with low eye pressures. Dr. Burns came highly recommended by a family member. And we are highly satisfied with the high level of professional care we received. We highly recommend his services to any person in need of eye surgery and treatment.”

Glaucoma Treatment Options

When glaucoma is diagnosed, the patient will be prescribed eye drops to lower the intraocular pressure. Other treatments include oral medications (which are rarely used, partly due to side effects), laser surgery, such as SLT treatment, and filtration surgery.

Selective Laser Trabeculoplasty for Glaucoma

Selective laser trabeculoplasty (SLT), a surgical treatment for elevated intraocular pressure (IOP) in patients with open-angle glaucoma, is an exciting recent development in open-angle glaucoma treatment. Prior to its introduction, oral medications and argon laser trabeculoplasty (ALT) were the primary treatment strategies for open-angle glaucoma.

How it Works

SLT works by using a specific wavelength of light to irradiate and target only the pigment-producing cells in the trabecular meshwork. The trabecular meshwork is the area which drains fluid from the eye. This is the area of the eye which is not working properly in open-angle glaucoma causing the fluid to not drain effectively, thus, resulting in elevated IOP. SLT treatment, unlike ALT treatment, does not cause any thermal damage to surrounding cells in the meshwork, thus causing less damage and scarring to these tissues. When the meshwork is treated with SLT, a biologic response occurs at the cellular level, thus leading to IOP reduction. The meshwork appears to drain fluid more easily than before treatment with SLT. This, in turn, reduces the risk that the glaucoma will progress. One of the advantages of SLT over ALT includes less thermal damage . Therefore, SLT can be repeated several times in the future, whereas ALT typically can only be repeated once. SLT has very few complications, the main one being a transient rise in IOP in the first hour after treatment. Results of SLT are very good to excellent in most patients. Patients who are using just one drop for controlling IOP have an 80% chance of a 4 to 8 point drop in their IOP after SLT treatment. Dr. Burns will discuss with you the best and most effective treatment options for your type of glaucoma. He is happy to provide SLT treatment in his office now in order to make it more convenient for you.

iStent ™

iStent ™The iStent™ is a tiny medical device that aids in permanently lowering eye pressure after it is implanted in the eye. The iStent allows fluid to escape by bypassing the trabecular meshwork thru the canal thus improving the natural outflow of the eye. This extremely small medical device helps your eyes maintain a healthy pressure level, significantly decreasing the risk of vision loss due to glaucoma.

The iStent™ is for patients who suffer with open-angle glaucoma and also need cataract surgery. If you have elevated eye pressure due to open-angle glaucoma, the iStent™ can help you safely maintain pressure levels without the hassle of a number of different eye drops. It is vital to maintain safe levels of eye pressure if you have glaucoma and this is one of the best ways to prevent vision loss associated with glaucoma.

The iStent™ has been approved by the FDA, and it is the smallest medical device to ever be gain their approval. This device is so small that it is 20,000 times smaller than the intraocular lenses used in cataract surgery. Once it is placed in your eye, you will not be able to see it.
