What to Expect During a Diabetic Eye Exam
A diabetic eye exam is important for every person with diabetes. It is an eye exam providing complete details of the eye structures this chronic condition affects. Having an eye exam specific to your condition can establish a good treatment plan. Understanding what to expect during your upcoming diabetic eye exam can help you prepare better. Here are the details.
Visual acuity test
The eye care provider will check the patient’s visual acuity by using an eye chart. Diabetes causes retinopathy. It deteriorates the tiny blood vessels providing blood to the eyes. This can result in many changes in the patient’s eyes. It can affect the clarity of the patient’s vision. That is why a visual acuity test is essential in a diabetic eye exam.
A reduced eye acuity may lead to refraction. This test’s aim is to see if the patient’s eyeglasses prescription has changed. The eye check will give way to the testing of new lenses. The visual acuity test will result in new prescription glasses.
Dilating eye drops are often present in a diabetic eye exam. This helps enlarge the diabetic patient’s pupils for a short while. This removes the eye’s natural reaction to light. The pupil dilation allows the eye doctor to see into the back of the eye to check the fundus of the retina. It will allow the eye doctor to spot any retinal damage from diabetes.
Eye-dilating eye drops will start dilating the patient’s pupils after about 20 minutes. This will happen while waiting in the reception area. The dilation will last for two to three hours. Wearing dark sunglasses after the diabetic eye exam is practical. Doing so will protect the eyes from overexposure to light.
Someone will need to drive the patient home because of this. The eye care provider can offer disposable sunglasses after the diabetic eye exam. The patient could throw the glasses away upon reaching home. Most patients prefer to nap off the effects of the dilation drops.
Studies show that glaucoma is one of the main causes of blindness. Diabetic retinopathy increases a diabetic patient’s risk for developing glaucoma. This is the reason behind a glaucoma test during a diabetic eye exam. This test involves measuring the pressure inside the eyes.
This is an imaging test for the back of the eye. The eye doctor will check if the retina is healthy. Examining the fundus can happen with specific procedures or instruments. An indirect ophthalmoscope can give the eye doctor a wider view of the back of the eye or retina.
The eye doctor can also use a direct ophthalmoscope. This is a hand-held instrument with a bright light. It allows the eye care provider to see the back of the eye. A slit lamp ophthalmoscopy uses a slit lamp during the diabetic eye exam. This provides a close, 3D view of the optic nerve, retina, and retinal blood vessels.
