Dry Eyes

This week’s topic covers the subject of dry eye.  This is a very common problem with many different causes. The symptoms include burning, watering eyes and a sensation of sand or grit in the eyes. It can be worse when driving, watching television and especially when using the computer or reading.  To understand how dryness affects the eyes, it’s helpful to understand normal tear function.

This week’s topic is diabetic eye disease.

Diabetes is a disease where the blood sugar becomes elevated.  It affects nearly 30 million Americans and nearly of third of  these people don’t know they have the disease. Diabetes can affect every part of the eye. 

Corneal Transplants

I have been asked many times in my career if the eye can be transplanted.  The short answer is no.  However, parts of the eye can be transplanted.  This week we’ll explore cornea transplants.


I hope everyone is enjoying the great weather we’re having.  Although we love these sunny days, there are some ways in which the sun and other forms of light can be damaging to the eyes.

One form of damage is called solar retinopathy.  It occurs when someone looks directly into the sun.  This can happen when viewing an eclipse.


Summer is finally here and it is time to celebrate the birth of our great nation.  That means enjoying fireworks.

Unfortunately, fireworks can be associated with eye injuries.  In 2014 there were 1,300 eye injuries from fireworks that required emergency treatment. That’s double the number from two years earlier.

Congential Eye Disease

This week I will describe some of the conditions that can be present at birth – congenital eye diseases. kids eyes.  The first is a disease called retinoblastoma.  This is a cancer of the retina that is often gentically inherited. 


Astigmatism. This week’s topic is astigmatism and how to correct it.  Astigmatism is a condition where the eye focuses the light in multiple locations on the retina.  


Welcome back to A Vision of Health.  Several past topics have mentioned refractive errors.  This week I will discuss this in detail. 

The eye works a lot like a camera.  Just as a camera focuses light on the film, the eye focuses light on the retina. When light is focused to a point, it is refracted.  When this point of light is perfectly on the retina the eye is emmetropic.  If the light is focused in front of or behind the retina, then the eye has refractive error.  

Lazy Eye

The subject of lazy eye is an interesting one because it is used to describe so many different conditions.  These conditions include strabismus which is a turning in, out, up or down of the eyes; amblyopia which is lack of visual development; refractive error which is a focusing problem; and ptosis which is a drooping of the eyelid.  The term lazy eye usually implies a condition that you’re born with and doesn’t go away.  After all, few cases of laziness are truly acquired.

Vision Floaters.

This week I will cover the topic of floaters.  These are the spots that move around in your vision.  They come in a wide variety of sizes and shapes.  There can be a single floater or many.  Each year I examine hundreds of patients who develop floaters.  Although floaters can be a sign of a problem in the eye, most of the time they are harmless.
