Eye Strain During Menstruation and Glaucoma Risks - Ophthalmology

During menstruation, the eyes can feel very fatigued?


Hello, doctor.
During my menstrual period, my eyes feel particularly dry and sensitive to light, and I easily get fatigued.
Is this normal? Additionally, I would like to ask about glaucoma.
Seven to eight years ago, during an eye examination, I accidentally discovered that my optic nerve head cup-to-disc ratio was larger.
Since then, I have been under regular follow-up at Chang Gung Memorial Hospital.
The doctor mentioned that she believes my larger cup-to-disc ratio is due to my myopia and not glaucoma, so there is no need for medication, but continuous monitoring is necessary.
Does this mean that I may not necessarily develop glaucoma? The doctor also said that the risk of glaucoma naturally increases with age, and I should approach eye examinations with a calm mindset.
Currently, I have been diligently returning for check-ups, and both my intraocular pressure and visual fields are normal.
I have noticed that a friend of mine also has a larger cup-to-disc ratio and has been advised to monitor it, but she feels fine and has not pursued follow-up.
Is it true that certain populations may have larger cup-to-disc ratios due to myopia or congenital factors, but it does not necessarily indicate glaucoma? However, no one can predict the future, so maintaining regular follow-ups is essential for eye health without excessive worry, right? Additionally, is there anything specific I should take for eye health, or should I avoid looking at the computer for long periods? (I read online that it is important to take breaks just like everyone else.)

Hello, Ayou: During menstruation, hormonal changes can lead to the dilation of blood vessels in the eyes, resulting in symptoms such as ocular congestion.
This may sometimes also trigger headaches, leading to discomfort in the eyes.
Individuals with myopia may have a more pronounced optic nerve cupping, but some people naturally have larger cupping, which does not necessarily indicate glaucoma.
It is essential to compare this with the results of a visual field test to determine if there is any concern.
If everything is normal, there is no need for worry; just continue to monitor the situation.
General eye care practices are sufficient.
For those who frequently use computers, the 20-20-20 rule is recommended: every 20 minutes of computer use, look away from the screen for 20 seconds and focus on an object 20 feet (6 meters) away.
Blinking 20 times during this break is even better.
The ophthalmology department at Puzi Hospital in Taiwan is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Online responses are for reference only; it is necessary to seek medical attention at healthcare facilities when needed.
I hope to have the opportunity to serve you.

Experiencing eye strain during menstruation is a common phenomenon that many women report. Hormonal fluctuations during the menstrual cycle can lead to various physical symptoms, including changes in vision and eye comfort. The increase in sensitivity to light, dryness, and fatigue you describe can be attributed to these hormonal changes, particularly fluctuations in estrogen and progesterone levels. These hormones can affect the tear film and overall eye moisture, leading to discomfort. While it is normal to experience these symptoms, if they become severe or persistent, it is advisable to consult an eye care professional.

Regarding your concerns about glaucoma, it is essential to understand that having a larger cup-to-disc ratio in the optic nerve does not automatically indicate glaucoma. The cup-to-disc ratio is a measurement used to assess the health of the optic nerve, and while a larger ratio can be a risk factor for glaucoma, it is not definitive on its own. Your eye doctor’s assessment that your larger cup-to-disc ratio is likely due to myopia (nearsightedness) is a common explanation, as myopia can lead to changes in the optic nerve structure.

Regular monitoring is crucial, especially as you age, since the risk of developing glaucoma does increase with age. Your proactive approach to follow-up appointments, including checking intraocular pressure and visual fields, is commendable. These tests help ensure that any changes in your eye health are detected early. It is true that some individuals may have a naturally larger cup-to-disc ratio without having glaucoma, and maintaining regular check-ups is the best way to monitor your eye health without unnecessary anxiety.

As for your friend who has a similar situation but is not following up, it is important to emphasize that regular eye examinations are vital, especially for individuals with risk factors like myopia or a family history of glaucoma. While it may seem that there are no immediate symptoms, glaucoma can develop silently, making routine check-ups essential for early detection and management.

In terms of eye care and maintaining good vision, there are several recommendations you can follow:
1. Regular Eye Exams: Continue with your routine eye examinations as recommended by your eye care professional. This is the best way to monitor your eye health.

2. Healthy Diet: Incorporate foods rich in antioxidants, vitamins A, C, and E, and omega-3 fatty acids into your diet. Leafy greens, carrots, fish, and nuts are excellent choices that can support eye health.

3. Screen Time Management: While it is essential to take breaks from screens, the general advice is to follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps reduce eye strain.

4. Proper Lighting: Ensure that your workspace is well-lit to reduce glare and strain on your eyes.

5. Hydration: Staying hydrated is crucial for maintaining tear production and overall eye comfort.

6. Protective Eyewear: If you spend a lot of time in front of screens, consider using blue light-blocking glasses to reduce eye strain.

7. Manage Dry Eyes: If you experience dryness, consider using artificial tears or lubricating eye drops, especially during your menstrual cycle when symptoms may worsen.

In conclusion, while hormonal changes during menstruation can lead to temporary eye discomfort, it is generally manageable. Your proactive approach to monitoring your eye health regarding glaucoma is wise, and maintaining regular check-ups will help ensure that any potential issues are addressed promptly. Remember to adopt healthy habits that support your eye health, and don’t hesitate to reach out to your eye care professional with any concerns.
