Glaucoma: Managing Eye Health and Vision Loss Risks - Ophthalmology

Share to:

Glaucoma, Vision Care


Hello, I am a 40-year-old software engineer with refractive errors of -4.50 and -4.75.
Out of curiosity, I tried the Amsler grid and discovered that when I cover one eye, I cannot see the upper left corner clearly with my right eye while focusing on the central black dot.
However, I had not noticed this before because my left eye compensated for it when using both eyes.
I visited an ophthalmologist last night and was diagnosed with glaucoma in my right eye, which has made me feel very anxious and unsettled.
(Intraocular pressure: left eye 18, right eye 27; cup-to-disc ratio: left eye 0.5, right eye 0.71; vision unchanged; visual field test: no defects in the left eye, but the upper left and superior peripheral vision in the right eye are completely black, covering about 30% of the total visual field.) I am slowly coming to terms with the reality and have researched a lot of related information.
I will actively adjust my lifestyle and medication (the doctor has prescribed Alphagan P).
I still have a few questions:
1.
Is glaucoma a bilateral disease? Will my left eye also be affected in the future?
2.
Currently, my vision is still normal with both eyes.
If I actively manage my condition, is there a real chance that I can maintain functional vision in my right eye for the rest of my life without going blind?
3.
Should I consider changing jobs to avoid further exposure to screens (I have currently changed my routine to take breaks every 30 minutes)?

Hello Louis: 1.
Glaucoma can occur in just one eye! 2.
If intraocular pressure is well controlled, the likelihood of optic nerve damage decreases, and it does not necessarily lead to blindness.
3.
Unless you are bored with your current job, there is no need to change jobs; glaucoma is not absolutely related to your work.

Hello! It sounds like you're going through a challenging time with your recent glaucoma diagnosis. I understand your concerns, and I’m here to provide some insights into managing your eye health and understanding glaucoma.

1. Is glaucoma a bilateral disease? Will my left eye be affected?
Glaucoma is often considered a bilateral disease, meaning it can affect both eyes, even if only one eye shows symptoms at the moment. The risk factors for developing glaucoma, such as increased intraocular pressure (IOP), family history, and age, can apply to both eyes. While your left eye is currently normal, it’s essential to monitor it closely. Regular eye exams will help detect any changes early, allowing for timely intervention if necessary.

2. Can I maintain my vision and avoid blindness in my right eye?
With proper management, many individuals with glaucoma can maintain their vision and lead fulfilling lives. The key is to adhere to your treatment plan, which may include medications like Alphagan P, regular follow-ups with your eye doctor, and lifestyle adjustments. Your current vision may remain stable if you manage your eye pressure effectively. It's crucial to monitor your vision regularly and report any changes to your healthcare provider immediately. Early detection of any deterioration can lead to timely adjustments in your treatment plan.

3. Should I change my job to avoid prolonged screen time?
While there is no direct evidence linking screen time to glaucoma progression, excessive screen use can lead to eye strain and discomfort, especially for someone with existing eye conditions. Taking breaks every 30 minutes, as you mentioned, is a great practice to reduce eye fatigue. You might also consider adjusting your workspace ergonomics, such as ensuring proper lighting and screen distance. If you find that your current job exacerbates your symptoms or increases your anxiety about your condition, it may be worth discussing potential changes with your employer or considering a role that allows for more flexibility in managing your eye health.


Additional Recommendations for Managing Glaucoma:
- Regular Eye Exams: Continue with your scheduled eye exams to monitor your IOP and visual field. Your eye doctor will assess the effectiveness of your treatment and make necessary adjustments.

- Medication Adherence: Ensure you take your prescribed medications consistently. If you experience side effects or have concerns about your medications, discuss them with your doctor.

- Healthy Lifestyle Choices: Maintaining a healthy lifestyle can positively impact your overall eye health. This includes a balanced diet rich in fruits and vegetables, regular exercise, and avoiding smoking.

- Stress Management: Managing stress is crucial, as anxiety can exacerbate your symptoms. Consider relaxation techniques such as meditation, yoga, or deep-breathing exercises.

- Educate Yourself: Understanding your condition can empower you to make informed decisions about your health. Continue to research and ask questions during your appointments.

In conclusion, while a glaucoma diagnosis can be daunting, many people successfully manage their condition and maintain their quality of life. By staying proactive about your eye health, adhering to your treatment plan, and making necessary lifestyle adjustments, you can significantly reduce the risk of vision loss. Remember, communication with your healthcare provider is vital, so don’t hesitate to reach out with any concerns or questions you may have.
