Branch Retinal Vein Occlusion and Central Retinal Vein Occlusion
We are reminded daily to live a healthy lifestyle, including a good diet and lots of exercise, but we don’t usually associate the risks associated with not doing so with the loss of our eyesight.
During a comprehensive vision examination, an eyecare practitioner will view the inside of the eye to look for any unusual changes there, especially concerning the circulatory system and the tiny arteries and veins that carry oxygen and nutrients to the tissues of the retina. It is fasc...

Central Retinal Vein Occlusion
A central retinal vein occlusion (CRVO) is a blood circulation problem. When the blood vessel called the central retinal vein becomes blocked suddenly it causes a rapid reduction in vision. It is like having a small “stroke” in the retina.
WHY IS VISION LOST?
The retina is the light-sensitive nerve tissue lining the back of the eye. Like film in a camera it takes “moving pictures” of everything you see. Your vision depen...

Fluorescein Angiography
Most people do not know that the only place in the human body where blood vessels can be viewed in their natural state, without cutting something open, is in the back of the eye. For this reason, the eye is one of the best places to evaluate diseases and conditions that affect the circulation; what is happening in the ocular blood vessels is also happening elsewhere in the body.
For this reason, Fluorescein Angiography (FA) , a test in which the vegetabl...

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 i...
