Intraocular Pressure and Maintenance


On May 5th of this year, I went to the Taipei Hospital of the Ministry of Health and Welfare for an ophthalmology examination due to military service requirements for a specialized re-examination.
At that time, I was not informed of any specific issues, but I did not see the results either.
Later, feeling uneasy, I went to a nearby clinic on May 6th to check my vision.
My myopia was measured at -8.75 diopters in both eyes, with astigmatism of -2.00 in the right eye and -2.25 in the left eye.
The prescription indicated an astigmatism axis (SCA) of 1 degree for the right eye and 158 degrees for the left eye.
The intraocular pressure in both eyes was 18 mmHg.
The doctor noted some redness in my eyes and prescribed "Systane Ultra" for fatigue and "Ning Shun Tong Eye Drops 0.005%" to reduce the redness.

On May 20th, after researching online, I suddenly realized I had some floaters.
I went to another clinic where a head-mounted fundus camera was used to examine my retina and fundus after dilation, and there seemed to be no issues, only some vitreous opacities.
However, the doctor mentioned that my intraocular pressure was slightly elevated but did not provide the exact value, prescribing "Timolol Maleate 0.5%" and "Ketotifen Fumarate," with a follow-up appointment in two weeks.
1.
I would like to ask the doctor, my left eye's myopia has increased by 50 degrees compared to four years ago.
What adjustments to my visual habits do you recommend, or are there other ways to prevent further increases in myopia? Currently, I take a 10-minute break every 40 minutes of near work; is this appropriate?
2.
My eyes seem to have had some redness for a long time, but they are not itchy, painful, or extremely red.
The doctor on May 6th mentioned that this could be reasonable if I frequently engage in outdoor activities due to UV exposure; is this correct?
3.
Regarding intraocular pressure, my readings on May 6th were below 20 mmHg, which seems to be within the average range.
However, during the May 20th visit, the doctor only mentioned that it was slightly elevated and prescribed medication to lower the pressure as a precaution against glaucoma.
What could cause elevated intraocular pressure? Besides eye drops, are there lifestyle changes that can help lower intraocular pressure?
4.
If my intraocular pressure is normal upon follow-up, how often do you recommend I have regular check-ups given my condition? Will I need to continue frequent visits to obtain medication to lower my intraocular pressure? I have previously experienced anxiety and have been on psychiatric medication; recently, due to these eye issues, my mental state has not been very good.
Thank you, doctor, for taking the time to answer!

Hello: 1.
Some studies suggest that the increase in myopia may be influenced by factors such as prolonged near work and extended use of digital devices.
Taking breaks for your eyes and engaging in distance activities, such as outdoor activities and looking at distant objects, can help alleviate the progression of myopia.
You have already established a good habit of resting for 10 minutes every 40 minutes.
2.
The appearance of bloodshot eyes can have many causes, including eye fatigue, dryness, fluctuations in intraocular pressure, and eye infections.
If you frequently engage in outdoor activities, exposure to ultraviolet light may cause the blood vessels on the surface of the eyes to dilate, leading to redness.
However, if your bloodshot eyes are not accompanied by other discomforting symptoms and do not persist for a long time, it does not necessarily indicate a serious problem.
3.
Elevated intraocular pressure may be one of the risk factors for glaucoma, a condition characterized by damage to the optic nerve.
However, elevated intraocular pressure does not necessarily mean that you will develop glaucoma, and other factors must be considered in the diagnosis of glaucoma.
The increase in intraocular pressure may be due to insufficient drainage or excessive production of aqueous humor.
In addition to eye drops, some studies indicate that maintaining a healthy weight, engaging in moderate exercise, avoiding excessive straining, ensuring adequate sleep, reducing stress, and following a proper diet may also help lower intraocular pressure.
4.
The frequency of regular eye pressure checks is usually determined based on individual circumstances and the physician's recommendations.
For the general population, if intraocular pressure is stable and normal, and there are no other eye issues, it is typically recommended to have an eye pressure check every 1 to 2 years.
However, since your physician has already diagnosed you with elevated intraocular pressure and prescribed lowering eye drops, this indicates that you may be at risk for glaucoma.
In this case, your physician may request more frequent eye pressure checks to monitor your condition.
The specific follow-up frequency should be determined by your physician based on your condition and treatment progress.
Medications to lower intraocular pressure usually need to be used regularly to maintain pressure within the normal range.
This may require ongoing medication for some time, along with regular follow-ups to ensure the effectiveness of the medication and control of intraocular pressure.
If your physician has prescribed lowering eye drops, it is best to follow their instructions and ask about medication usage recommendations during follow-up visits.

Managing eye pressure is crucial for maintaining overall eye health, especially for individuals with a history of high myopia or other ocular conditions. Based on your situation, here are some tailored recommendations and insights to help you manage your eye health effectively.


1. Adjusting Eye Care Habits
Given your myopia of 875 degrees and the increase of 50 degrees over four years, it’s essential to adopt healthy visual habits. Your current practice of taking a 10-minute break every 40 minutes of near work is a good start. This aligns with the 20-20-20 rule, which suggests that for every 20 minutes of screen time, you should look at something 20 feet away for at least 20 seconds. This helps reduce eye strain and fatigue. Additionally, consider incorporating the following practices:
- Proper Lighting: Ensure that your workspace is well-lit to reduce glare and strain.

- Screen Position: Keep your computer screen at eye level and about an arm's length away to minimize strain.

- Blink Regularly: Remind yourself to blink often, especially when using screens, to keep your eyes moist.


2. Understanding Eye Redness
The presence of bloodshot eyes can be attributed to various factors, including environmental irritants, fatigue, or prolonged screen time. If you spend significant time outdoors, UV exposure can indeed contribute to eye redness. To mitigate this:
- Wear Sunglasses: Use UV-blocking sunglasses when outdoors to protect your eyes from harmful rays.

- Stay Hydrated: Drink plenty of water to maintain overall hydration, which can also help with eye moisture.


3. Managing Eye Pressure
Your eye pressure readings of 18 mmHg are generally within the normal range, but fluctuations can occur. Factors that can lead to elevated eye pressure include:
- Genetics: A family history of glaucoma can increase your risk.

- Medications: Certain medications can affect eye pressure.

- Diet and Lifestyle: High caffeine intake, lack of exercise, and poor diet can contribute to increased eye pressure.

To help lower your eye pressure naturally, consider:
- Regular Exercise: Engaging in physical activity can help lower eye pressure.

- Healthy Diet: Incorporate foods rich in omega-3 fatty acids, antioxidants, and vitamins A, C, and E. Leafy greens, fish, nuts, and fruits are excellent choices.

- Limit Caffeine: Reducing caffeine intake may help manage eye pressure.


4. Frequency of Eye Exams
Given your history and current eye pressure concerns, regular monitoring is essential. If your eye pressure stabilizes, a follow-up every six months to a year may be sufficient. However, if you continue to experience fluctuations or if your doctor recommends, more frequent visits may be necessary. Always follow your ophthalmologist's advice regarding medication and follow-up appointments.


5. Mental Health Considerations
It’s understandable that dealing with eye health issues can lead to anxiety. It’s important to address your mental well-being alongside your physical health. Consider:
- Mindfulness and Relaxation Techniques: Practices such as meditation, yoga, or deep-breathing exercises can help reduce anxiety.

- Professional Support: If your anxiety persists, discussing your concerns with a mental health professional can provide additional coping strategies.

In conclusion, managing eye pressure and maintaining eye health involves a combination of good habits, regular check-ups, and a healthy lifestyle. By being proactive and attentive to your eye care, you can help prevent further deterioration and maintain your vision. Always consult with your eye care professional for personalized advice and treatment options tailored to your specific needs.
