Pupil dilation examination

Hello, Doctor.
I had a dilated eye exam around 3 PM today.
The doctor mentioned that I might have floaters after seeing some dark spots, but after the examination, he said there were no signs of retinal tears and that I should just monitor the situation.
During the exam, the doctor used a light and instructed me to look in various directions—up, right, and so on—before asking me to look straight ahead again.
I started to tear up a bit, possibly due to the brightness, and afterward, I felt slightly dizzy for about 3-5 seconds.
When I looked at my phone, I experienced a strange sensation.
Although I feel mostly fine after resting, I wanted to ask if the dizziness was normal.
Also, why do I still feel a bit odd when looking at my phone while wearing glasses? Lastly, the doctor didn't specifically ask me to return for a follow-up, and I forgot to ask if I should continue to have check-ups as long as I'm not experiencing the dark spots.
Thank you.

Hello: Regarding the sudden feeling of dizziness you mentioned, this may be due to your pupils being dilated by the mydriatic agent, which increases the amount of light entering your eyes, leading to eye fatigue and temporary visual adaptation issues.
Typically, this sensation of dizziness will resolve quickly.
If this feeling persists or worsens, it is advisable to have an eye examination.
As for the strange sensation you experience even after wearing glasses, this may be because your eyes are still under the effects of dilation, and it should return to normal once the pupils constrict.
Lastly, if you notice any visual abnormalities or changes in symptoms in the future, such as shadows or flashes of light, it is recommended that you seek assistance from an ophthalmologist promptly.

More Info

After undergoing a dilation eye exam, it's not uncommon to experience some temporary symptoms, including dizziness or a feeling of disorientation. This can be attributed to several factors related to the dilation process and the nature of the examination itself.

Firstly, during a dilation exam, the eye doctor uses special drops to widen the pupils, allowing for a better view of the retina and other internal structures of the eye. This process can make your eyes more sensitive to light, which may cause discomfort or a sensation of being overwhelmed by bright lights. The bright examination lights used during the check-up can also contribute to this feeling. When you are asked to look in different directions, it can further strain your eyes, especially if they are already sensitive from the dilation.

The dizziness you experienced for a few seconds after the exam could be a result of a combination of factors: the bright lights, the sudden changes in focus as you looked in different directions, and possibly even a slight drop in blood pressure from sitting or standing quickly. It’s important to take your time when transitioning from sitting to standing after an eye exam, especially if you feel lightheaded.

As for the strange sensation when looking at your phone after the exam, this could be due to residual effects of the dilation drops. Dilation can temporarily alter your vision, making it difficult to focus on close objects, such as your phone screen. This is particularly true if you have a pre-existing condition like myopia (nearsightedness), which can be exacerbated by the dilation process. Your eyes may also still be adjusting to the changes in light and focus, leading to a feeling of strangeness or discomfort when viewing screens.

Regarding your concern about the black spots you mentioned, if your doctor did not indicate any immediate need for follow-up, it is likely that they assessed your condition and determined that monitoring is sufficient for now. However, if you notice any changes in your vision, such as an increase in the number of floaters, flashes of light, or any new symptoms, it is advisable to return for a follow-up examination. Regular check-ups are essential, especially if you have a history of floaters or other visual disturbances.

In summary, experiencing dizziness and unusual sensations after a dilation exam can be normal and is often temporary. It is essential to give your eyes some time to adjust and to avoid straining them with screens immediately after the exam. If symptoms persist or worsen, or if you have any new concerns, do not hesitate to reach out to your eye care provider for further evaluation. Regular monitoring and communication with your healthcare provider are key to maintaining good eye health.
