Optomap® Images Increase Ocular Pathology Detection

Sunday, February 28th, 2010

Information in this article has been re-posted from The Eye Doc Blog (www.theeyedocblog.com).

Results from a pilot study conducted by doctors at the New England College of Optometry* were recently presented at Optometry’s Meeting and the American Academy of Optometry.  In the study, subjects were examined using the methods of traditional ophthalmoscopy and optomap®assisted ophthalmoscopy, where an ultra-wide field retinal image from the  optomap® guides the retinal examination.

Forty subjects underwent undilated imaging with the optomap®. Subjects were then dilated and underwent traditional ophthalmoscopy and optomap®assisted ophthalmoscopy. The traditional exam consisted of BIO and slit lamp biomicrosopy with precorneal lenses. Optomap®assisted ophthalmoscopy was identical to traditional, with the exception that the doctor reviewed optomap® Images before performing their BIO examination. A masked Reader graded the optomap® Images of all subjects. A retinal specialist examined 28 of the 40 subjects and served as the gold standard.

Sensitivity and specificity of the optomap® Image review in detecting retinal lesions were compared to sensitivity and specificity of both traditional and optomap®assisted ophthalmoscopy. The results indicate that using optomap® Images increases pathology detection. Sensitivity of the Reader (image review alone) outperformed traditional ophthalmoscopy by approximately 15%, while sensitivity of optomap®assisted ophthalmoscopy outperformed traditional ophthalmoscopy by approximately 30%. Specificity was comparable across all methods.

“I believe the increased sensitivity is due to the optomap® field of view and in part to the software capabilities. Being able to magnify and zoom-in, adjust the gamma, contrast and brightness as well as using the individual red and green laser separations allows the examiner to really hone in on areas of interest,” said Kristen Brown, OD, FAAO, the Principal Investigator.

Data from a statistically powered study is currently being analyzed, with results expected in 2010.

Schedule an appointment with one of the eye doctors at Iowa EyeCare today to have your eyes examined.

Eye Disease in Ancient Egypt

Sunday, February 14th, 2010

Ancient Egyptian eye makeup may have been more therapeutic than cosmetic.

Egyptian Eye

In the days of the ancient Egyptian empire, the Nile River delta was a place where eye infections were likely commonplace, as sanitation and hygiene practices were not established. 

The periodical, Analytical Chemistry, recently published an article regarding the lead-based compounds found in the tombs of ancient Egyptians.  Their conclusion is that “lead-based compounds were used during antiquity as both pigments and medicines in the formulation of makeup materials.”

 ”According to ancient Egyptian manuscripts,” says Analytical Chemistry, ”these were essential remedies for treating eye illness and skin ailments. This conclusion seems amazing because today we focus only on the well-recognized toxicity of lead salts.”  Analytical Chemistry goes on to say that, “one may argue that these lead compounds were deliberately manufactured and used in ancient Egyptian formulations to prevent and treat eye illnesses by promoting the action of immune cells.”

In modern times, ocular infections still cause problems for millions of people each year.  If you think you might have an infection, walk like an Egyptian to Iowa EyeCare.  Iowa EyeCare has a doctor on-call 24 hours a day, 365 days a year, call 319-377-2222.

Obesity and the Eye

Sunday, January 17th, 2010

 By Dr. Ryan W. Nelson

  
The visual system is vulnerable to the effects of excessive body weight.  Numerous eye conditions are caused by or accelerated as a result of obesity.  Maintaining a healthy body weight will reduce your risk of getting these eye conditions and many others:

A personal decision to make lifestyle changes is the most important step in fighting obesity.  Obesity is often the result of high caloric consumption and low caloric utilization.  It is for this reason that the primary treatment for obesity is to change diet and exercise habits.  Use the food pyramid provided to help you choose the right foods to eat.  The doctors at Iowa EyeCare recommend at lease 30 minutes of moderate-intensity physical activity each day.  Don’t forget to include aerobic and muscle-strengthening exercise in your routine.

Obesity is increased body weight caused by excessive accumulation of fat to the extent that ones health is negatively affected.  Excessive body weight is associated with diabetes type 2, cardiovascular disease, cancer, and many other systemic conditions.  The consequence of obesity is a reduction in life expectancy by almost 7 years and unfortunately new evidence tells us that the prevalence of obesity is rising in both children and adults.

Don’t Underestimate the Importance of Sun Protection for Your Eyes

 Dr. Kimberly Cruise
 
 You know sun protection is important for your skin.  The eyes need sun protection too.  Even during the Iowa winter months.
 
 Iowa EyeCare strongly recommends all of our patients wear UV eye protection when outdoors, even on cloudy days and even during the Iowa winter.  Limit you time in direct sunlight, wear a wide-brimmed hat, and always wear sunglasses.  Sun protection is especially important in children.  Significant UV damage occurs in children when the eyes are not properly protected from the sun because their eyes do not filter UV as well as adults.

The radiation you receive from the sun is known to cause multiple adverse eye conditions including:

Save Money! If you have insurance that allows you to get new frames, why not make your old glasses into sunglasses?

What does the term “lazy eye” mean?

Monday, December 14th, 2009

By Dr. Dennis Francis

Dr. Dennis Francis

 I often hear patients say they have (or think they have) a lazy eye. The term “lazy eye” is actually synonymous with the medical term “amblyopia”. Amblyopia occurs when one eye fails to provide adequate vision and the brain begins to collect visual information from only the better eye. The poorer seeing eye subsequently fails to develop normally. If left untreated, amblyopia results in a best-corrected vision of worse than 20/20 and reduced binocular vision.

amblyopia

Amblyopia is most often a consequence of unequal glasses prescription between the two eyes or from monocular strabismus (one eye turning in or out). It is very difficult to re-train the brain once it decides not to use the amblyopic eye. Amblyopia is one of the most common causes of vision loss in children because it often arises without symptoms. Routine eye examinations play a key role in preventing vision loss from amblyopia.

The American Optometric Association and the eye doctors at Iowa EyeCare agree that even if no eye or vision problems are apparent, at about age 6 months, you should take your baby to your doctor of optometry for his or her first thorough eye examination. We can offer helpful suggestions to prevent amblyopia and, if necessary, begin treatment for any eye-related problems.

 

Please schedule an appointment with an eye doctor at Iowa EyeCare in Cedar Rapids, Marion, or Robins, Iowa.

Young Mother Develops Cancer of the Eye

Monday, November 30th, 2009
Dr. Noyes

Dr. Richard Noyes

The importance of routine examinations cannot be under stated.  The light-sensitive retina (located on the back, inside surface of the eye) should be examined at least annually, even for those with perfect vision.  The following is a real-life example of why a retinal exam is so important. 

Not long ago, a 32-year-old, single mother of three came to Iowa EyeCare’s Marion office to see optometrist Dr. Richard Noyes for an eye exam and to get new contact lenses. She had no symptoms and was in good health.
Melanoma+OM

Melanoma of the Eye

 

 

An Optomap® retinal exam was performed.  The image of the right eye is shown here and has a dark oval lesion: melanoma.  This patient was sent to the University of Iowa to see an ophthalmic oncologist (an eye-cancer doctor) and the eye was removed 3 days later.

Cancer of the eye is deadly.  The early diagnosis made by Dr. Noyes saved this woman’s life.  Fortunately, she doing fine and was fit with a prosthetic eye. 

 

 

Don’t wait to schedule your next eye exam.  We have locations in Cedar Rapids, Marion and Robins, Iowa.

Scratched Eye

Monday, November 9th, 2009

By Dr. Dennis Francis

 

The doctors at Iowa EyeCare have a different term for “scratched eye”.  We call it a corneal abrasion.  The cornea is the clear window in front of the colored part of your eye.  It’s about the thickness of a credit card and has 5 different layers.  The front or top layer, the epithelium, is designed to protect the rest of the cornea, but it’s also very sensitive and susceptible to damage.  When the epithelium is injured by an abrasion, the eye is at risk contracting an infection.  Corneal infections can have severe consequences, including permanent vision loss.

Prompt care can help to protect the eye and prevent permanent vision loss.  An antibiotic eye drop is usually required to help thwart infection and get you feeling better again. Your doctor may also choose to use additional medications or even a bandage contact lens, depending on the nature of the injury.  Either way, close monitoring of the abraded eye is critical.  It is important to follow up as directed by your Iowa EyeCare optometrist.

Prevention is always the best medicine.  Never forget to use safety glasses when it is appropriate, especially when doing yard work or working with metal.  A scratched eye can be very painful and it is important to seek medical care immediately.  At Iowa EyeCare we have a doctor on call 24 hours and day, 7 days a week, 365 days a year, to care for any type of eye emergency.

If you or someone close to you has an eye emergency, you’ll want to call us right away.  Our phone number is 319-377-2222.  Keep number on hand, so when bad things happen your prepared.
