Normal-Tension Glaucoma: Symptoms and Concerns for Patients - Ophthalmology

Hello, Chen Xiaoyan,
Thank you for reaching out with your concerns regarding normal-tension glaucoma (NTG) and your overall eye health. As a patient with high myopia, it’s understandable that you might be feeling anxious about your vision and the potential implications of your recent diagnosis. Let’s address your questions one by one.

1. Can normal-tension glaucoma cause rainbow vision (halos)?
While halos around lights are more commonly associated with acute angle-closure glaucoma, they can also occur in patients with normal-tension glaucoma. This phenomenon is often due to changes in the cornea or lens, which can be exacerbated by high myopia. The presence of halos, especially at night when looking at bright lights, can be a result of corneal irregularities or other refractive issues rather than directly from NTG itself. However, it’s essential to discuss this symptom with your ophthalmologist, as they can provide a more tailored assessment based on your specific eye condition.

2. What are the symptoms of normal-tension glaucoma?
Normal-tension glaucoma can be insidious, often progressing without noticeable symptoms until significant damage has occurred. Common symptoms may include:
- Gradual loss of peripheral vision, which may lead to tunnel vision in advanced stages.

- Difficulty adjusting to changes in lighting, particularly moving from bright to dim environments.

- Occasional eye discomfort or pressure, though this is less common than in other forms of glaucoma.

- In some cases, patients may experience visual disturbances such as halos or blurred vision, especially in low-light conditions.

It's important to note that many patients with NTG may not experience any symptoms until the disease has progressed significantly. Regular eye examinations, including visual field tests and optic nerve assessments, are crucial for monitoring the condition.

3. Can I continue weight training and roller training?
Engaging in physical activities like weight training and roller training is generally safe for individuals with normal-tension glaucoma. However, it’s advisable to avoid exercises that involve straining or holding your breath, as these can temporarily increase intraocular pressure. Instead, focus on maintaining a balanced routine that includes moderate cardiovascular exercises, flexibility training, and strength training with proper techniques. Always consult with your healthcare provider or a fitness professional who understands your eye condition before making significant changes to your exercise regimen.

In addition to addressing your specific questions, I want to emphasize the importance of managing your anxiety regarding your eye health. It’s common for patients to feel overwhelmed when faced with potential diagnoses like glaucoma. Engaging in relaxation techniques, such as mindfulness or yoga, can be beneficial. Furthermore, maintaining regular follow-ups with your ophthalmologist is crucial for monitoring your condition and adjusting treatment as necessary.

If you have any further concerns or if your symptoms change, please do not hesitate to reach out to your healthcare provider. They can provide you with the most accurate information and support tailored to your needs.

Wishing you peace of mind and good health,
Best regards.
