Visual field analyzers are great tools that have become the standard of care for diagnosis and management of eye diseases that result in visual field loss.

A visual field analyzer is essential in the diagnosis of glaucoma, and is used extensively to monitor other diseases of the optic nerve, retina and visual pathways. Visual field analyzers can even be used to detect life-threatening conditions such as brain tumors!

The GDx test is a relatively new test that has proven to be useful in the diagnosis and management of glaucoma.

The GDx is a tool that uses laser to determine the thickness of the nerve fiber layer. This procedure is painless and is usually performed on un-dilated pupils. The thickness of the nerve fiber layer is then compared with the nerve fiber layer of a normal eye. The GDx maps the nerve fiber and compares them to a database of healthy glaucoma free patients. A thinning of the fiber indicates glaucoma.

All of this is put together and made available to doctors in the form of pictures, graphs and statistical data that indicates the probability of glaucoma. The use of this tool is very helpful in early detection and management of glaucoma because it detects very small changes when compared with previous GDx data.

This helps doctors to decide whether the patient truly has glaucoma or should be considered a “Glaucoma suspect”.  

The Auto Refractor/Keratometer is the equipment we use to measure the spherical, cylindrical and axis which are components that make up the patients’ prescription.

This equipment also measures the corneal curvature of the eye as well as pupil distance and size. This can also be used to detect certain eye diseases such as Keratoconus. 

 
An OCT is a tool that can be used to show the individual nerve fiber layers composing the eye. It gives your eye doctor the ability to do a non-invasive cross-sectional analysis of your eye.

OCTs can be used to measure glaucoma, macular degeneration, retinopathy and macular holes. Your eye doctor can use the high-definition scans to better explain your vision and any problems you may be experiencing.

A fundus camera is a special camera system that can be used to photograph the microscopic inside of your eye.

Taking yearly photographs of your eyes, particularly in diseased eyes, can help precisely pinpoint progression or changes that take place from exam to exam.

These photographs are great tools in treating diseases such as diabetes and macular degeneration.

A corneal topographer can be used to produce a topographical map of the front surface of the eye.

It is vital for properly selecting and fitting contact lenses and for anyone who is considering any type of eye surgery involving the cornea.

A corneal topographical map can also help your eye doctor more precisely understand your vision problems and prescribe more accurate treatment.

A pachymeter is a device that is used to measure the thickness of the cornea in micrometers.

Pachymetry is a vital measurement for patients who undergo eye surgeries such as LASIK. It is also extremely helpful for patients suffering from keratoconus.

Tonometry is the way eye doctors determine the pressure inside the eye.

It is important to have this checked to help determine early signs of Glaucoma. There are several ways to measure the pressure inside the eye.

Below are two ways used at Dickson EyeHealth Center.

The NCT or Non-contact tonometry is used to determine the pressure of the eye without actually touching the eye. The NCT uses a puff of air against the cornea to measure the pressure. due to this, no contact with the eye is needed.

The Tono-Pen is another way to measure the pressure inside the eye. The Tono-Pen actually touches the front of the eye to determine this pressure. Due to this fact we use a drop to numb the eye so our patients don’t feel this touch. A new cover is used for each patient to protect against cross contamination.

There are other forms of tonometry that can be used to double check the readings given by these two tests.

We have an anterior segment camera linked with our Biomicroscope that can take pictures of diseases or a foreign body on the anterior structures of the eye. This is needed for follow-up purposes.

Biomicroscopy – a microscope that allows us to see in detail the anterior structures of the eye. When using an additional lens we can see the posterior pole of the eye in three dimensions.

Dickson EyeHealth Center is completely electronic when it comes to medical records! The United States government requires that all physicians use electronic medical records by the year 2014.

Dickson EyeHealth Center has embraced the technology and is proud to offer you the new standard in medical record keeping.

Electronic medical records make it possible for physicians in many disciplines to communicate and collaborate on your healthcare issues, and many common transcription errors can now be avoided with electronic records.
