An initial undilated exam is just as crucial as the dilated exam because it can provide your eye doctor with valuable information. When your eyes are undilated, your eye doctor can test your vision, examine the front of the eye such as the iris, and can also take measurements that will help determine your eyeglass prescription.
Although your eye doctor can see the macula and optic nerve when the pupil is undilated, this view is limited and does not provide a thorough exam. By dilating the pupils with dilation eye drops, the entire retina can be viewed.
When your eyes are dilated, you can expect an increase in light sensitivity. This is because the pupil is large, allowing more light to come through. Your vision may also become blurry, especially when trying to read. You may also experience a different sensation or a feeling of tightness in your eyelids.
Dilated eye exams can be used to diagnose conditions such as:
Diabetic retinopathy and age-related macular degeneration (AMD) are two common retinal diseases. They are both diagnosed and monitored through an examination of the retina via a dilated pupil.
Glaucoma is a condition that affects your optic nerve. While your eye doctor can view your optic nerve without dilating your pupils, they must dilate the pupils to get a full, comprehensive view to examine for optic never conditions like glaucoma.
Regular comprehensive eye exams are crucial to keeping your eyes healthy. In addition to updating your prescription, a comprehensive eye exam can also help to provide an early diagnosis of severe eye conditions, allowing for early treatment and the prevention of vision loss. With a comprehensive dilated eye exam, Dr. Dittman and his experienced staff can determine the health of your retina and optic nerve to help preserve your vision health.
