Glaucoma, Dry Eyes, and Visual Disturbances in Teens

Glaucoma and dry eye syndrome associated with photophobia issues?

Hello Doctor, I would like to ask a few questions:
1.
If I go for a fundus examination due to floaters, will the doctor be able to check for symptoms of macular degeneration or glaucoma?
2.
A few months ago, I noticed that sometimes I see halos around lights, but I don't feel anything special when I see rainbows.
However, my eyes often feel fatigued.
A previous doctor diagnosed me with dry eye syndrome, so my eyes sometimes swell and feel similar to symptoms of glaucoma.
Later, the doctor performed some tests, asked me to focus on a chart, and conducted other examinations.
He said my eye pressure was 20, which is on the borderline of normal, and advised me to return for a check-up in six months.
He mentioned that my optic nerve looked good, so it should not be glaucoma.
Does this mean glaucoma has been ruled out?
3.
If it is not glaucoma, why do I see halos? The doctor later prescribed artificial tears for me and only advised me to return for a follow-up in six months, without explaining the cause of the halos or how to resolve them.
I still occasionally see halos; what can I do to address this?
4.
After using the artificial tears prescribed by the doctor, my eyes felt a bit better at first, but then they became more acidic.
Recently, my eyes often feel sore, and I feel discomfort after watching TV for a short time.
The artificial tears don't seem to be effective.
What should I do?
Thank you, Doctor, for patiently reading this.
I hope to receive answers.
I am only 17 years old and am very afraid of losing my vision.

Hello! Thank you for your questions regarding your eye health concerns, particularly about floaters, visual disturbances, and the possibility of glaucoma. I understand that these issues can be quite worrying, especially at your age. Let’s address your questions one by one.

1. Will the doctor check for macular degeneration or glaucoma if I go for a retinal examination due to floaters?
Yes, when you visit an eye doctor for floaters, they will typically perform a comprehensive eye examination, which includes checking the retina and assessing for any signs of macular degeneration or glaucoma. The examination often involves dilating your pupils to get a better view of the back of your eye, allowing the doctor to evaluate the health of your retina and optic nerve.

2. If my eye pressure was measured at 20 mmHg and the doctor said my optic nerve looks good, does that rule out glaucoma?
A pressure reading of 20 mmHg is indeed on the higher end of the normal range, but it does not automatically indicate glaucoma. The fact that your doctor mentioned your optic nerve looks good is a positive sign, as glaucoma typically causes damage to the optic nerve. However, it’s important to continue monitoring your eye health, as glaucoma can develop over time. Your doctor’s recommendation to return in six months for a follow-up is standard practice to ensure that any changes can be detected early.

3. What could be causing the rainbow vision (halos) if it’s not glaucoma?
Halos or rainbow vision can be caused by several factors, including dry eyes, which you mentioned you have. When the tear film is unstable, it can lead to visual disturbances, including halos around lights. Other potential causes could include corneal irregularities or even the effects of certain medications. Since your doctor prescribed artificial tears, it suggests that they believe your symptoms are related to dry eyes. If halos persist, it’s essential to follow up with your eye doctor for further evaluation.

4. What should I do if the artificial tears are not providing relief and my eyes feel more acidic or fatigued?
If you find that the artificial tears are not effective and your eyes continue to feel uncomfortable, it’s crucial to revisit your eye doctor. They may need to adjust the type of artificial tears you are using or explore other treatments for your dry eyes. Sometimes, preservative-free artificial tears can be gentler on the eyes. Additionally, your doctor may recommend other treatments, such as punctal plugs, which can help retain moisture in your eyes.

In summary, while your current symptoms may not indicate glaucoma, it’s essential to keep monitoring your eye health. Regular check-ups with your eye doctor are vital, especially since you are experiencing visual disturbances and discomfort. Remember, early detection and management are key to maintaining good eye health. If you have any further concerns or if your symptoms worsen, do not hesitate to seek medical advice sooner rather than later. Your vision is important, and taking proactive steps can help protect it.
