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

Ocular Hypertension
As you read in the The Basics of Glaucoma article if we were to randomly sample the eye pressures of 1000 people off the street nearly all those sampled would have a pressure under 21 mm (of mercury). But if your pressure is greater than 21 does 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 hypertension. Will you be treated? If you have ocular hypertension you may be wondering i...Read More

Ocular Rosacea
Ocular rosacea is associated with a chronic skin condition known as rosacea or acne rosacea. This common problem usually affects those with light skin and in the early stages is characterized by redness and bumps concentrated on the forehead nose and cheeks. One of the earliest symptoms of rosacea often experienced during puberty is facial flushing. Flushing for any reason is liable to bring on an attack of redness and pimples. Even people who are being treated for rosacea can relapse if th...Read More

Oily Fish Consumption Protect Your Eyesight
People who habitually consume oily fish at least once a week compared with less than once a week are 50% less likely to have wet AMD. Eating oily fish once a week may reduce age-related macular degeneration (AMD) which is the major cause of blindness and poor vision in adults in western countries and the third cause of global blindness according to a study published in the American Journal of Clinical Nutrition. There are two types of AMD wet and dry. Of the two wet AMD is the main cause of...Read More

Open Angle Glaucoma
Glaucoma is caused by a number of different eye diseases that in most cases produce increased pressure within the eye. This elevated pressure is caused by a backup of fluid in the eye. Over time it causes damage to the optic nerve and can result in blindness . Open-angle glaucoma the most common form of glaucoma affects over 3 million North Americans - half of whom don t know they have it. Early detection diagnosis and treatment can help prevent serious vision loss and blindness. Think of your ...Read More

Open Your Eyes To Healthy Eating Habits
In honor of March s Save Your Vision Month the American Optometric Association (AOA) reminds Americans that caring for eyes includes paying attention to nutrition. Approximately 43 million Americans suffer from age-related macular degeneration (AMD) or cataracts the two leading causes of vision loss and blindness. Based on research from multiple studies there is a strong correlation between good nutrition and the prevention of these age-related eye diseases. By eating foods rich in six nutri...Read More

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...Read More

Optic Neuritis
Optic neuritis (also called retrobulbar retinitis) is an inflammation of the optic nerve the “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 mild vision can be almost normal but severe inflammation can cause loss of vision. Optic neuritis can occur in one or both e...Read More

Optic Neuritis/ Retrobulbar Neuritis
Optic Neuritis is an inflammation of the optic nerve, which leaves the back of the eye and exits into the brain at the back of the bony orbit of the skull. The optic nerve serves the very important function of getting visual information from the eye into the brain and to the visual cortex, located in the back of the head. Sometimes this condition is referred to as Retrobulbar Neuritis, in order to reflect that it is located behind the eye. Typically, a patient arrives in their optometrist...Read More

Optical Illusions
Our visual system constantly imposes three-dimensional characteristics onto two-dimensional images. While our interpretations of these images are usually correct in ambiguous situations with more than one possible image our brain may not see all of the possibilities. In such situations there 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: Both images are the...Read More

If you are nearsighted when you look at distant objects the light entering your eye focuses in front of the retina resulting in blurry vision. This condition called myopia can be corrected by wearing glasses or contact lenses through laser surgery or now with a procedure called Orthokeratology. Orthokeratology often referred to simply as Ortho-K is a reversible non-surgical process that uses a specialty contact lens to gently reshape the cornea of your eye while you sleep. Highly oxygen ...Read More
