You might think that your eyes are absolutely healthy when there are no symptoms, but it’s important to visit an eye doctor near me for a dilated eye exam, as many eye conditions don’t present with symptoms initially. Annual dilated exams are often recommended, but the frequency is dependent on many factors and varies from patient to patient. This blog discusses what a dilated eye exam is and the importance of a dilated eye exam.
What is a Dilated Eye Exam?
A dilated eye exam is a thorough check of the inner parts of your eye, like the retina and optic nerve. During the exam, eye drops are used to widen or “dilate” your pupils. Dilating the eyes for an eye exam is to let in more light to give the eye doctor a clearer view of any potential issues. The process is simple and usually painless.
The Importance of Dilated Eye Exams
A dilated drop allows the pupil to open up so the posterior segment of the eye is examined fully, like the peripheral retina, which is otherwise difficult to view without dilation. The importance of dilated eye exams is to diagnose and treat glaucoma timely manner, a disease that has destroyed the lives of numerous Canadians and Americans. A dilated eye exam allows your optometrist to fully assess the condition of your eyes.
Eye dilation for an eye exam can save your vision when a serious condition is detected. Accessing the peripheral retina with the eyes dilated may lead to the eye doctor detecting retinal holes, breaks, tears, or detachment.
RD, also known as retinal detachment, involves the separation of the neurosensory layers of the retina from the underlying pigments and epithelium and can lead to vision loss if not detected and treated urgently. Often, retinal detachment is preceded by a PVD (posterior vitreous detachment), which sometimes gives the patient warning signs of flashes, floaters, or shadows.
However, symptoms are often absent in the presence of asymptomatic retinal compromise. A routine dilated pupil eye exam can lead to the discovery of such conditions and allow for timely treatment and management.
Three Factors to Consider When Getting a Dilated Eye Exam
1. Age
The risk of ocular disease is higher with advanced age, so eye dilation and eye exams become more critical. Annual exams become more important in advanced age when changes are likely to take place, and the chances of eye diseases increase.
2. Eye health
If you had been diagnosed with a posterior segment eye disease previously, your doctor may ask you to get an eye dilation exam more frequently.
3. Tumors and high myopia
People who have had tumours or high myopia are asked to get dilated eye exams more frequently as they are in a higher-risk group.
What to Expect during a Dilated Eye Exam
1. Eye Drops
First, the doctor uses eye drops to widen your pupils. They sting a bit at first, but it’s quick. Then, you wait about 15 to 30 minutes as your vision slowly goes blurry, letting more light into your eyes than usual. It’s strange, but it’s what lets the doctor see into the deeper parts of your eye.
2. The Exam Itself
When your pupils are fully dilated, the doctor will shine a bright light and examine your retina, optic nerve, and blood vessels to have a close-up look so they can detect abnormalities. They search for any signs of conditions like glaucoma or diabetic eye disease that often stay silent until it’s too late.
3. Blurry and Light-Sensitive Vision After the Exam
After the exam, things can feel a bit off. Your vision might still be blurry, and light will seem intense. Sunglasses help. If you’re not used to this, you might feel a little disoriented, but it doesn’t last long. This short, sometimes awkward experience gives you peace of mind, knowing you’re catching potential issues before they affect your sight.
How Often Should You Get a Dilated Eye Exam?
If you’re younger, in your 20s or 30s, with no eye issues, every few years might be fine. But once you’re around 40, regular exams every 2 to 4 years become important, even if you think your vision is perfect. Eyes change with age, and they sometimes do so quietly; detecting symptoms early can make a big difference.
For those 60 and up, have a yearly eye dilation exam. Risks like glaucoma or macular degeneration become more common, and regular checks give you the best shot at early detection. And if you have specific risks like diabetes or a family history of eye issues, these exams might need to be more frequent. Costs and OHIP coverage for eye exams in Toronto can influence how often people schedule their visits, as explored in eye exam costs and OHIP coverage in Toronto.
The takeaway from all of this is that you shouldn’t wait for symptoms to show before you begin trying to find an eye clinic for dilated eye exams. A dilated exam is one small step that helps keep your vision safe, especially as time goes by.
Dilated Eye Exam vs. Regular Eye Exam: What’s the Difference?
A regular eye exam checks your vision, sharpness, and your eye health in general. It’s quick, as your doctor might ask you to read letters, test your focus, or look at eye movements. But this exam only covers the surface.
Eye dilation and eye exams go further. After placing drops in your eyes to widen your pupils, the doctor can look directly at the back of your eye. This lets them examine the retina, optic nerve, and blood vessels to find early signs of serious eye issues like glaucoma or retinal problems.
Without dilation, these parts stay hidden, making it harder to catch diseases early. So, if you’re at risk for certain conditions or haven’t had one in a while, a dilated eye exam in The Beaches, Toronto, offers a deeper look for insights that a regular exam just can’t reach.
How Long Do Dilated Eyes Stay Dilated
After a dilated eye exam, your eyes typically stay dilated for about 4 to 6 hours, though this can vary based on individual factors and the type of drops used. Some people might notice that their pupils stay enlarged for a shorter or longer time. During this period, your vision may be blurry, and you’ll be more sensitive to light, so wearing sunglasses outdoors can help.
If you have lighter-colored eyes, like blue or green, dilation might last a bit longer, as lighter eyes often respond more to the drops.
Conclusion
A comprehensive dilated eye exam lets your optometrist better assess your ocular health. A thorough and regular dilated eye exam is always recommended to ensure that your eyes are free from any disorder or complications. Most especially, people with diabetes, high blood pressure, eye tumours, infectious diseases, retinal detachment, glaucoma, and macular degeneration are recommended to get their eyes checked regularly.
