Corneal abrasion

Dear Dr.
Gao,
I apologize for the interruption during your busy schedule.
I would like to ask a couple of questions:
1.
I previously read a book called "Matsuzaki Vision Improvement Method," which mentioned a 15-point eye exercise routine that involves eye movements.
It states that training for two hours daily can improve vision from 0.1 to 1.2 in two weeks.
Is there any evidence that such training can actually reduce myopia?
2.
I have been wearing rigid gas permeable contact lenses for over a decade.
On December 15 of last year, I experienced dryness in my eyes due to eye exercises, which caused a stinging sensation when wearing the lenses and led to a corneal abrasion that healed in about three days.
On April 9 of this year, I again experienced dryness from eye exercises, resulting in another corneal abrasion (the stinging sensation occurs only when wearing contact lenses).
Would this be considered a recurrence? (I have only experienced these two incidents in the past ten years.) After healing, is there a risk of scarring?
Thank you for your guidance.

Hello:
1.
The Matsuzaki vision enhancement method should primarily train the six extraocular muscles responsible for eye movement.
Myopia is caused by an increase in the axial length of the eyeball.
I believe that appropriate eye exercises can provide rest for the eyes, but I remain skeptical about the claim that these exercises can reduce myopia.
2.
Corneal epithelial damage typically heals well with proper rest, usually within a day, without causing scarring.
If wearing contact lenses causes a slight stinging sensation, it is best to remove them and allow the eyes to rest for a day or two before reapplying, to prevent further injury to the cornea.
In the past ten years, I have only experienced two instances of corneal abrasion, which is not considered recurrent, and there was no scarring after recovery.
Dry eyes can more easily lead to corneal abrasions, and since you are wearing rigid gas permeable contact lenses, it is even more important to maintain corneal moisture.
If necessary, you should consider using artificial tears.
Thank you for your message.

More Info

Corneal abrasions are a common eye injury that can occur due to various causes, including trauma, foreign bodies, or even excessive eye rubbing. Understanding the causes, treatment options, and preventive measures is crucial for maintaining eye health, especially for individuals who wear contact lenses or engage in activities that may put their eyes at risk.

Causes of Corneal Abrasions
Corneal abrasions can result from several factors:
1. Trauma: This includes scratches from fingernails, branches, or other sharp objects. Even minor injuries can lead to significant discomfort.

2. Foreign Bodies: Dust, sand, or other particles can scratch the surface of the cornea.

3. Contact Lenses: Improper use of contact lenses, such as wearing them for too long or not cleaning them properly, can lead to abrasions. Hard lenses, like the ones you mentioned wearing for over a decade, can be particularly irritating if they do not fit well or if the eye becomes dry.

4. Eye Rubbing: Rubbing the eyes, especially when they are itchy or irritated, can lead to abrasions.

5. Dry Eyes: Insufficient tear production can make the cornea more susceptible to injury.

Treatment of Corneal Abrasions
The treatment for corneal abrasions typically includes:
1. Rest: Avoiding contact lenses and giving the eye time to heal is essential. In your case, since you have experienced abrasions after performing eye exercises, it may be wise to take a break from such activities until your eyes are fully healed.

2. Topical Antibiotics: These may be prescribed to prevent infection, especially if the abrasion is significant or if there is a risk of foreign body contamination.

3. Pain Management: Over-the-counter pain relief medications can help manage discomfort. In some cases, your doctor may prescribe stronger pain relief.

4. Lubricating Eye Drops: These can help alleviate dryness and discomfort, especially if you are experiencing dry eyes.

5. Follow-Up Care: Regular check-ups with an eye care professional are important to ensure proper healing and to monitor for any complications, such as scarring.

Prevention of Corneal Abrasions
Preventing corneal abrasions involves several strategies:
1. Proper Contact Lens Care: Ensure that you follow the recommended guidelines for wearing and caring for your contact lenses. This includes cleaning them properly and replacing them as directed.

2. Protective Eyewear: When engaging in activities that could pose a risk to your eyes, such as sports or yard work, wearing protective eyewear can help prevent injuries.

3. Avoid Eye Rubbing: If your eyes are itchy or irritated, try to avoid rubbing them. Instead, use lubricating drops to relieve discomfort.

4. Manage Dry Eyes: If you experience dry eyes, consider using artificial tears or consult with an eye care professional for appropriate treatments.

Regarding Your Specific Questions
1. Vision Training: The claims made in books about vision training, such as the one you mentioned, often lack robust scientific backing. While certain eye exercises may help with eye strain or improve visual comfort, they are unlikely to significantly reduce myopia (nearsightedness). Myopia is primarily a refractive error that typically requires corrective lenses or surgical intervention for significant changes.

2. Recurrent Corneal Abrasions: The two instances of corneal abrasions you experienced could be considered recurrent if they are related to similar activities or conditions, such as dry eyes from wearing contact lenses. It is essential to monitor your symptoms and consult with an eye care professional if you experience pain or discomfort again.

3. Scarring: While most corneal abrasions heal without scarring, deeper abrasions or repeated injuries can lead to scarring. If you notice persistent discomfort or visual changes after healing, it is advisable to seek a follow-up examination.

In summary, corneal abrasions are manageable with proper care and preventive measures. If you continue to experience issues, particularly with your contact lenses, consulting with an eye care professional is crucial for tailored advice and treatment options.
