Unlike a routine eye exam that assesses your visual system and eye health, anyone who was diagnosed with type 1 or type 2 diabetes requires an additional test for their eye exam. Traditionally, everyone had their pupils dilated in order to get a clear picture of the eye, however, with modern advances in technology, many practices are adding a digital retinal exam as well.
The Beginning of the Dilated Eye Exam
When your eye doctor starts the dilated eye exam, he or she will administer dilating drops in each eye, which will enlarge your pupils to give the optometrist a better view of certain parts of the back of the eye. The drops can take about 20 to 30 minutes to take effect, but the effects last well beyond the exam up to several hours, so it is advisable not to drive yourself home after the eye exam.
Why Does an Optometrist Dilate the Eyes?
Enlarging the pupils will allow for more light to enter the eye. This provides your eye doctor the ability to use a special magnifying lens to examine the tissues at the back of the eye, including the retina, the macula, and the optic nerve.
For anyone with diabetes, these exams are essential as diabetic retinopathy is a leading cause of blindness. By examining a greater range of the eye’s interior, the diabetic eye exam can detect signs of swelling or leaking of blood vessels in the retina. Detecting early signs of diabetic retinopathy allows us to diagnose and treat eye diseases to prevent permanent vision loss.
After the Dilated Eye Exam
While people might relax at the optometrist’s office until the effects start to fade, it’s recommended that you invest in a pair of polarized sunglasses. In some cases, your optometrist may supply you with a free, generally temporary, pair of sunglasses to protect your eyes. While tinted lenses can reduce the amount of light that enters the eyes during the time your eyesight is extra sensitive, the added protection from polarization is essential.
A Healthy Diet Plays a Role in Diabetic Eye Disease Prevention
For further information about how diabetes plays a role in your vision, call our office to schedule your annual diabetic eye exam. The findings from your diabetic eye exam can give your eye doctor important information about your overall health, particularly diabetes and high blood pressure. Plus, your optometrist can help you manage your diabetes and prevent the progression of the condition. For example, most diabetics know that nutrition is a key factor in maintaining a normal, healthy lifestyle. Your eye doctor is a great resource to review your diet and can advise you on what foods are recommended and what to avoid.
