| OCT - OPTICAL COHERENCE TOMOGRAPHY |
This revolutionary test allows doctors an opportunity to better understand and view disease progression of the macula, the retina and the optic nerve long before actual vision loss takes place. Routine analysis of the retina utilizes manual and photographic views of the top layers or simply its surface. OCT tomography provides a more detailed look at the retina with a three-dimensional side-view or optical cross-section.
This procedure provides a more precise analysis of the important ... Read More

But if your pressure is greater than 21does it mean that there is trouble ahead for you? Does it mean that you’re headed toward glaucoma? Not necessarily.
You may have what’s known as ocular hypert... Read More

Over timeit causes damage to the optic nerve and can result in blindness .

Optical Illusions
Our visual system constantly imposes three-dimensional characteristics onto two-dimensional images. While our interpretations of these images are usually correctin ambiguous situations with more than one possible image our brain may not see all of the possibilities. In such situationsthere are many factors simultaneously influencing our vision. Below are a few pictures that will help demonstrate this point. Image #1 What do you see: two faces or a vase? Hint: Bo... Read More

| OPTIC DISC DRUSEN |
The optic nerve is the transmission cable that connects the retina of the eye to the brain. Anatomically, the optic nerve consists of over one million retinal cells called ganglion cell axons. The face of the optic nerve that is seen during examination of the central retina is called the optic disc. This face of the optic nerve or disc is void of the seeing elements of the retina, specifically the rod and cone cells, and as a result, the optic nerve is naturally a non-seeing part of the...

| Optic Neuritis |
Optic neuritis (also called retrobulbar retinitis) is an inflammation of the optic nervethe “cable” that transmits visual information from the eye to the brain. (Optic = eye; retrobulbar = behind the eye; neuritis = nerve inflammation.) The optic nerve plays such a key role in vision that anything that happens to it affects eyesight. When inflammation is mildvision can be almost normalbut severe inflammation can cause loss of sight. Optic neuritis can occur in one or both eyes. ... Read More
