WHAT IS FUNDUS PHOTOGRAPHY?

Fundus photography involves photographing the rear of an eye; also known as the fundus. Specialized fundus cameras consisting of an intricate microscope attached to a flash enabled camera are used in fundus photography. For some patients, this can be performed instead of being dilated.  Your eye doctor can observe and evaluate the health and condition of the blood vessels in your retina, which are a good predictor of the health of blood vessels throughout your body. Conditions such as diabetes, hypertension and hypercholesterolemia all are visible by changes in the appearance of the retinal blood supply and blood vessels. If you are Diabetic or Pre-Diabetic, most insurance companies will require the dilation procedure as it is the standard of care.

SHOULD YOU SLEEP IN YOUR CONTACTS?

If you have ever accidentally gone to sleep with your contact lenses in, you may have experienced the difficulty in trying to remove them from your dried out eyes. Sleeping in your lenses can increase your risk for infections, or at the very least irritation and discomfort. Even though there are lenses approved for overnight wear, many Optometrists recommend giving your eye a chance to breathe without lenses. Daily disposable lenses have made this problem easier to address, because you can simply toss out the old pair every night and put a new pair in every morning.
