What are diabetes eye exams?

Routine eye examinations can reveal a lot of different things about a patient like what type of prescription grade the glasses they need or what kind of contact lenses would be best for them.

What a patient has diabetes, the eyes are usually implicated and could incurred considerable damage as the condition progresses. Usually, the smaller blood vessels in the patient’s retina become affected and this results in a condition called diabetic retinopathy. Regular eye examinations are very important in the early detection of diabetic retinopathy because the signs will only be discovered under the close inspection of a diabetic eye exam. This means that the patient may not even know that their eyes are getting damaged in the process.

How often do I need to get a diabetic eye exam?

It is recommended that a patient go in for a regular eye check once every year or once into years by the doctor that is qualified to carry out a diabetic eye exam.

These eye drops are especially formulated to dilate the pupils of the eyes, but the patient may feel a singing sensation when the drops are administered initially. Some patients have also reported a metallic taste in the mouth during this step.
  • Using a machine that can both magnify and illuminate the eyes, the doctor can begin to assess certain areas of the eyes such as the blood vessels from the front to the middle section of the eyes, the back portion of the eye, and the optic nerve itself.

Are there any risks to getting a diabetic eye exam?

The risk involved with a diabetic eye exam usually comes with the administration of the eye drops that are used to dilate the pupils of the eyes during the examination. Some patients have reported that they experienced blurry vision up to six hours after the administration of the dilating solution. Because of this, it will also be harder for the patient to focus on the objects that they are looking at until the effects of the solution has worn off. In relation to this, patients must take care to protect their eyes from the direct glare of the sun or other light sources because the dilated pupils will make the eyes highly sensitive to light for as long as the effects of the solution are active.
