Optometry and Ophthalmology Working Together, Not Separately

Posted by Ilena Di Toro | Posted on April 13, 2021

There was a time when optometrists and ophthalmologists did not work together. If you talk to older optometrists and ophthalmologists, you will learn that they considered each other rivals. Now many optometrists and ophthalmologists work together, either in a co-management capacity or within the same practice. One reason for this is the growth of refractive […]

This Arc is More Plastic than Wooden

Binocular vision is a good thing. It allows humans to judge distance and depth, which gives us the ability to distinguish the relationship between objects. When the eyes aren’t in their correct position or can’t focus on the same object, then there are vision problems. It can lead to conditions such as strabismus, also known […]

Visual Processing Part Two

Posted by Ilena Di Toro | Posted on March 16, 2021

Since it was identified which cells do what for vision, the next question is what part of the brain is in charge of processing visual information? Vision is more complicated than it seems. For the longest time, it was thought that vision was a matter of an image that is cast on the retina and […]

Visual Processing Part One

More than 50 percent of our brain is dedicated to visual processing. Yet there is so much going on. How do our brains process the information that is coming in from our eyes? One research project at Max Planck Institute of Neurobiology in Munich, University of California Berkeley and Harvard University looked at the retinal […]

Cataracts and the Zika Virus Affect Vision Development

Posted by Ilena Di Toro | Posted on February 16, 2021

When babies are born, they can see an object with their peripheral vision but their central vision is still developing. Over the first few weeks, as a baby’s retina develops, his or her pupils widen and the baby can see light and dark ranges and patterns. At one month, a baby may briefly focus on […]

Cutting the Fat & Turning Back the Clock

Posted by Ilena Di Toro | Posted on February 2, 2021

During the coronavirus lockdown, many people used this time to exercise more. As a result, their clothes aren’t as tight and they felt better. The bad thing about the lockdown is that it led to a lot of shortages, like toilet paper. Too bad we can’t turn back the clock to February 2020 and stock […]

Research

Thanks to biomedical research, our understanding of the human body is evolving and this has led to treatments that improve health outcomes. This includes vision research and as a result, more is being learned about what leads to amblyopia and a possible treatment for age-related macular degeneration (AMD). Amblyopia Amblyopia, also known as lazy eye, […]

Good for One, Bad for Another

Posted by Ilena Di Toro | Posted on January 5, 2021

Vascular Endothelial Growth Factor (VEGF) is a protein that our bodies produce to promote the growth of new blood vessels. This is a good thing since more blood vessels mean more oxygen goes to the tissues. The lungs have VEGF because blood flow is so important. Of course, what’s good for one organ isn’t good […]

On/Off Switches Part Two

Posted by Ilena Di Toro | Posted on December 23, 2020

In On/Off Switches Part One I wrote about research done at the Oklahoma Medical Research Foundation (OMRF) that discovered a compound that controls the growth of blood vessels. This can be utilized for conditions ranging from diabetic retinopathy to cancer. They aren’t the only ones doing this type of research. Scientists at Johns Hopkins have […]

On/Off Switches Part One

Posted by Ilena Di Toro | Posted on December 8, 2020

Isn’t electricity great? You flip a switch and an appliance turns on or off. Wouldn’t it be nice if there was a way to do something similar for our bodies, in particular our eyes. That way when an injury or disease comes along, something in the cellular level could be turned on or off and […]
