Mydriatics and photophobia?

Hello, Doctor.
I am 18 years old.
I have been continuously monitored for my eye condition at a large hospital for a total of six years, from middle school until my high school graduation.
To control my myopia, the doctor prescribed me Atropine 0.3% eye drops.
During this period, my myopia did not worsen significantly (left eye -3.75, right eye -4.25).
However, after I stopped using the eye drops upon graduating high school, I noticed that my eyes became quite sensitive to light.
Just 2-3 days after stopping the drops, I would start to experience light sensitivity, but this would resolve once I resumed using the drops.
I would like to ask the doctor: 1.
What should I do about my eyes moving forward? 2.
Does this mean I will have to continue using the eye drops indefinitely? I also have quite severe floaters, but they have remained stable.
3.
Is this a serious side effect of the eye drops? 4.
Is my situation considered unusual? 5.
Could there be other underlying issues with my eyes, or do I believe this is primarily related to the eye drops? 6.
If I continue using the drops, is there a risk of developing glaucoma or other eye diseases? I kindly ask for your response amidst your busy schedule.

Hello, Student Lin:
1.
At your age, you can gradually stop the medication.
2.
Typically, stopping the medication should not cause photophobia; it may be that the ciliary muscle starts to function again after discontinuation, leading to discomfort when exposed to light.
This discomfort may resolve in a week or two, and during this period, you can use sunglasses to alleviate the discomfort.
3.
This is relatively uncommon.
4.
You can try to persist for a week or two; you may eventually get used to it.
5.
If you currently do not have glaucoma, it is unlikely to develop later, but it is advisable to try stopping the medication.
6.
The ophthalmology department at Puzi Hospital in Taiwan is open on Monday, Tuesday, Thursday, and Friday from 8:00 AM to 12:00 PM, and on Wednesday from 2:00 PM to 4:30 PM.
Online responses can only serve as a reference; if necessary, you should visit a medical institution for treatment.
I hope to have the opportunity to serve you.
Best regards,
Gao Pilin

More Info

Hello! Thank you for your detailed questions regarding your eye health and the effects of pupil dilation, particularly in relation to the use of atropine. Let's address your concerns one by one.

1. What should I do about my eyes now?
Given your history of using atropine to manage myopia, it's important to consult with your ophthalmologist about your current sensitivity to light. This sensitivity may be a temporary reaction to discontinuing the medication, as atropine can cause prolonged dilation of the pupils, affecting how your eyes respond to light. Your doctor may suggest a gradual tapering of the medication or alternative treatments to manage your myopia without causing discomfort. Additionally, wearing sunglasses outdoors can help mitigate light sensitivity while you adjust.

2. Will I need to continue using the dilating drops indefinitely?
It's not uncommon for some individuals to experience light sensitivity after stopping atropine, but this does not necessarily mean you will need to use it indefinitely. Your eye doctor will evaluate your specific situation and may recommend a different approach to managing your myopia that does not involve continuous use of atropine. Regular follow-ups are essential to monitor your eye health and adjust your treatment plan as needed.

3. Is this a serious side effect of the dilating drops?
Light sensitivity can be a side effect of atropine, but it is not typically classified as a serious adverse effect. However, if the sensitivity is affecting your daily life or causing significant discomfort, it is crucial to discuss this with your ophthalmologist. They may consider other underlying factors contributing to your symptoms.

4. Is my situation unusual?
While some individuals may experience light sensitivity after discontinuing atropine, the severity and duration can vary widely. Your experience is not unheard of, but it is essential to communicate openly with your eye care provider about your symptoms to determine the best course of action.

5. Could there be other underlying issues with my eyes?
It's possible that other factors could contribute to your light sensitivity, including dry eyes, underlying refractive errors, or other ocular conditions. Your ophthalmologist can perform a comprehensive examination to rule out any additional issues and ensure that your eyes are healthy.

6. Could continuous use of atropine lead to glaucoma or other eye diseases?
Atropine is generally considered safe for managing myopia, and there is no direct evidence linking its use to the development of glaucoma. However, any long-term medication use should be monitored by a healthcare professional. Your doctor will assess your risk factors for glaucoma and other eye diseases during your regular check-ups.

In summary, while your sensitivity to light after stopping atropine is concerning, it is essential to have an open dialogue with your ophthalmologist. They can provide personalized advice and treatment options based on your specific needs. Regular monitoring and communication will help ensure your eye health remains stable and that any potential issues are addressed promptly. Remember to protect your eyes from bright lights and consider wearing sunglasses when outdoors to alleviate discomfort.
