Dilated Eye Exams Increase Quality of Life for Seniors

Wednesday, January 11th, 2012

human eye 300x137 Dilated Eye Exams Increase Quality of Life for SeniorsA recent study showed that dilated eye exams were a low-cost method of increasing quality of life for seniors.   The study revealed that, in patients with no previously diagnosed eye problems, a dilated eye exam increased the quality of life of the individual 7 x more than just a simple check of the vision chart at the primary care doctor’s office.

In fact, the U.S. Preventative Services Task Force recently withdrew their support for simple vision chart screenings with a primary care doctor as a meaningful way to increase a person’s quality of life.

Why?  A simple vision chart test may not accurately reflect a person’s ability to see clearly and effectively in all situations.   But, even more importantly, it fails to assess many ocular conditions which threaten a person’s quality of life.     Just a few of these conditions are glaucoma, cataracts, macular degeneration, and diabetic retinopathy.     A dilated eye examination with an eye care provider could identify many other eye conditions and even signs of systemic diseases that may have gone unnoticed during regular physicals with the primary care physician.

I cannot stress enough how important the annual comprehensive eye exam is to a person’s vision, long-term ocular health, their overall health, and (as this study shows) quality of life.

How Can Head Trauma Affect Your Eyes?

Monday, May 9th, 2011

One question we ask of all our patients is  “do you have any history of head trauma?”

The overall delicate nature of the eyes makes trauma relevant with any degree of impact to the head.   This could be as simple as slipping on a banana peel at the Cartoon Caveman Hitting Another Caveman Over the Head with a Club 101119 235128 102042 How Can Head Trauma Affect Your Eyes?Norfolk Zoo and hitting the head on the ground or as severe as being run over by a tourist while crossing Atlantic Ave in Virginia Beach.

In terms of the ocular effects of head trauma, there are several different parts of the eye which may be affected.    Here’s a few of the possibilities:

Hemorrhage on the front surface of the eye.

This one looks bad.   This may just be some simple leakage from capillaries, but it could also be a sign of more significant and deeper tissue damage.

Angle Recession and Glaucoma:

The “angle” of the eye is a collection of structures in which internal fluid is drained into the blood stream.  In trauma, the angle structures can be pulled apart and this is called “angle recession.”  This, in turn, can damage the drainage function.   When this happens, fluid within the eye may build up and eye pressure may rise above normal levels

When eye pressures rise as a result of trauma, glaucoma can result.    Glaucoma is a progressive deterioration of the optic nerve which can cause blindness.

Unfortunately, elevated eye pressure and glaucoma are most often not noticed by patients until the process is far along.    This is yet another important reason for getting annual eye exams.

Retinal Detachments:

This is the big one!    Retinal Detachments, in most situations, need immediate attention to prevent further vision loss.   Signs of a retinal detachment include sudden increase in floaters, large dark spots in vision, a veil or curtain coming over a portion of your vision, and/or flashing lights.    Even if a person is not experiencing these symptoms after head trauma, it is still recommended to get a full retinal evaluation to ensure the retina is intact.

Cataracts:

The internal lens of the eye is where traumatic cataracts will occur.   This damage can certainly cause noticeable changes in vision.   However, unlike glaucoma, most cataracts can be completely remedied through surgery and the vision restored.

These are just a few of the common affects of trauma on the eyes.   There are literally entire books on the subject.    Yet, the main point is if you’ve had a recent incident of head trauma, no matter the severity, see your eye doctor for a complete dilated exam;  and if you’ve had head trauma in the past, make sure to get regular eye examinations and remind your doctor of this history.

Ask Dr. Beach: Visual ‘Floaters’

Tuesday, February 9th, 2010

Ask Dr. Beach:  “What are these floaters or spots I’ve had in my vision?” Ask Dr. Beach logo1 300x158 Ask Dr. Beach:  Visual Floaters

Floating spots or strands within your vision, also known as “floaters,” are a pretty common occurrence and in some cases can be pretty annoying.   Despite the annoyance, floaters are not cause for concern.   However, exceptions do exist and caution should exercised so as to not mistake floaters for other more serious ocular health risks.

Most often, you may see floaters as clear, translucent, or hazy strands or dots in your vision.

floaters squiggly lines Ask Dr. Beach:  Visual FloatersThey may be more noticeable when looking at bright lights or white backgrounds.    These floaters are actually shadows cast on your retina by strands within a portion of your eye called the vitreous.   The vitreous is a gel-like sphere that helps the eye maintain its shape, but over time the gel material starts to dissolve.  As a result particles will be cast throughout the vitreous, and it’s these particles that cast the shadows onto the retina.  While annoying, this is a normal aging process within the eye.   However, caution should be used if simple floaters present more pronounced or if accompanied by other symptoms, such as flashes of light.

One important aspect of the vitreous is that it is attached to your retina at several places.  CO0071 Ask Dr. Beach:  Visual Floaters Over time, the same process that causes floaters also causes the vitreous to sink in on itself.   Once the weight of the sinking vitreous becomes too great, it will detach from the retina.   This is called a Posterior Vitreous Detachment and will cause more pronounced, darker and much more noticeable spots or floaters in the central part of your vision.   The tugging force on the retina created by the detaching vitreous may even cause a person to experience flashes of light in their vision.

In a small percentage of cases, the tugging force placed on the retina by a Posterior Vitreous Detachment can cause a retinal tear or detachment.  This is considered a medical emergency and warrants immediate attention to determine whether laser or retinal surgery will be required to prevent permanent vision loss.

Overall, floaters in your vision, if few and constant are most likely harmless and should be discussed with your optometrist at your yearly exam.   If those floaters are accompanied with flashes, or if the floaters become larger and more numerous, you should see your optometrist right away to check for Posterior Vitreous Detachment or retinal tears or detachments.
