Does a light tap on the eyeball affect the retina?

Dear Dr.
Hu,
Thank you for your detailed answers to my previous questions! I have high myopia in my right eye and have undergone retinal laser treatment to ensure my retina is healthier.
I would like to ask you:
1.
Last night, while I was sleeping, my finger accidentally brushed against my right eyeball.
Could this have an impact on my retina?
2.
A colleague mentioned that people with high myopia should avoid rubbing their eyes.
Is this true?
I appreciate your assistance in answering these questions.
Thank you!

Hello: Individuals with high myopia should indeed avoid pressing, squeezing, or rubbing their eyes (this is generally advised for everyone as well).
The eyeball, much like a basketball, is a closed space, and any pressure applied to it can cause a sudden increase in intraocular pressure.
Given that the walls of the eyeball (sclera) and the retina in those with high myopia are thinner than in individuals without myopia, the risk of injury due to this sudden increase in pressure is significantly higher.
If you accidentally pressed on your right eye, please pay attention to the same considerations mentioned previously.
Thank you for your inquiry.
Wishing you peace and good health.

Dear Patient,
Thank you for your thoughtful questions regarding the effects of light pressure on the eyeball, especially in the context of your high myopia and previous retinal laser treatment. I appreciate your concern for your eye health, and I will address your questions in detail.

1. Light Pressure on the Eyeball and Its Effects on the Retina: When you apply light pressure to the eyeball, such as a gentle poke or touch, it is unlikely to cause significant harm to the retina, especially if the pressure is brief and not forceful. The retina is a delicate layer of tissue at the back of the eye, and while it is sensitive, it is also designed to withstand minor external pressures. However, in individuals with high myopia, the retina can be thinner and more susceptible to damage. If you have had previous retinal laser treatment, your retina may be more stable, but it is still essential to be cautious. If you experience any unusual symptoms such as flashes of light, sudden vision changes, or persistent discomfort, it is advisable to seek an eye examination promptly.

2. Avoiding Eye Rubbing in High Myopia: Your colleague is correct; individuals with high myopia should be particularly cautious about rubbing their eyes. Rubbing can exert significant pressure on the eyeball, which may lead to complications such as retinal tears or detachment, especially in those with pre-existing conditions like thinning of the retina. The act of rubbing can also cause corneal abrasions or exacerbate existing conditions like keratoconus. It is essential to maintain good eye hygiene and avoid touching or rubbing your eyes unnecessarily. If you feel the need to relieve discomfort or itchiness, consider using lubricating eye drops instead of rubbing.

In addition to these points, it is crucial to maintain regular eye check-ups, especially given your history of high myopia and retinal treatment. Regular monitoring can help catch any potential issues early and ensure that your eyes remain healthy. If you have any concerns about your vision or eye health, do not hesitate to consult your eye care professional for personalized advice and treatment options.

In summary, while light pressure on the eyeball is generally not harmful, it is essential to be cautious, especially with a history of high myopia. Avoiding eye rubbing is a wise practice to protect your retina and overall eye health. If you have any further questions or experience any concerning symptoms, please reach out to your eye care provider.

Take care of your eyes, and thank you for your trust in seeking advice on this important matter.
