We were proud to have been one of the first practices in Oklahoma City to acquire one of the newest generation OPTOVUE RTVue OCTs (optical coherence tomographer). OCT technology has been around since 1991. The RTVue is a Fourier-domain based OCT. This simply means it is extremely fast and accurate. Older OCT scanners captured approximately 400 scans per second or the retina. The RTVue can capture about 26,000 scans of the retinal layers per second. This allows us to see great detail of the retina, down to 5 micron resolution. The RTVue is useful for imaging ocular structures from the front of the eye to the back of the eye with extreme detail.
What this means to you, is we are able to identify retinal irregularities sooner and easier and with greater detail, which can lead to earlier diagnosis and treatment, potentially saving vision loss. This is very useful for following patinets with diabetes and macular degeneration, and other retinal disease. This machine also useful for earlier detection of glaucoma and other optic neuropathies. The RTVue is accurate in imaging the nerve fiber layer. This layer contains approximately one million nerve cells that give us vision. Glaucoma can cause thinning and loss of the retinal nerve fiber layer, and detecting this loss earlier can aid in early diagnosis of glaucoma and potentially save or reduce vision loss in some patients, by instigating treatment sooner.
The RTVue is also useful for imaging the front of the eye, including corneal thickness and symmetry, which is very important prior to LASIK. The anterior drainage angle of the eye can be measured as well which is important in narrow-angle glaucoma, one of the leading causes of blindness world wide.
The overall value of the RTVue lies in our ability to use it for more accurate diagnosis, and to aid in treatment decisions. This allows us to determine if further referral to more specialized care is indicated or not. In the end can save health care dollars.

An irregular corneal shape can lead to reduced or distorted vision, and even monocular double vision. The refraction of light through your eye begins with the cornea. Having a healthy cornea is very important to having sharp vision.
Canon CR-DGI Retinal Camera
This 10.2 mega pixel retinal camera can aid us in getting magnified digital images of the retina, the back tissue of the eye. A good photo is always better then a drawing, and this can help us in tracking retinal disease as it progresses year to year, or if it remains stable. Baseline retinal photographs are encouraged for everyone, especially those with a family history of retinal disease, or newly diagnosed diabetic patients. Retinal photos are easy to send to other providers if referral care is needed, which helps with continuity of care.
Retinal photos are seen as the standard of care in following some forms of ocular disease, like glaucoma.
One of the best reasons we like our high resolution camera is for the education of all our patients. When we are able to take an image of the retina and explain what is going on the photo to the patient and family members it often helps in the understanding of the disease, which in turn can help with compliance with treatment, and follow up, which in the end can save health care dollars down the road.
LASEREX Ophthalmic YAG Laser
There are some laser procedures that we can do in the office, to treat several conditions in the front of the eye. The YAG laser can be used to open up a "hazy film or capsule" that can occur following routine cataract surgery. This film, or "after-cataract" can caused blurred vision months to years after cataract surgery. Not every person gets this "hazy film or capsule", but if it does happen, we can take care of this in the office with a quick procedure. This proceudre is called a YAG Capsulotomy. We are happy that we can offer this to our patients, and save them a trip to the hospital or another out patient facility.
This YAG laser can also be used to treat acute glaucoma, when the front drainage angle of the eye becomes closed. The YAG laser can create a hole in the peripheral iris, to allow fluid inside the eye to flow from behind the iris to areas in front of the iris. This can deepen the front chamber of the eye, to help reduce eye pressure. Angle closure glaucoma is the most common form of glaucoma world wide, and more common in those of Asian decent.
