Post-traumatic sequelae of eye injury?


Doctor, I was punched in the left eye, and after an examination by an ophthalmologist, I was told that there are no issues with my fundus or retina.
I have previously undergone laser surgery for my myopia, and I occasionally experience a dull pain.
I would like to know if there could be any other long-term effects, such as an increase in astigmatism or a rise in floaters.
Additionally, I have noticed an increase in floaters in my right eye recently, which I feel may be related to my frequent computer use.
Will resting more improve my symptoms?

Hello: If the force is not very strong, these sequelae should not occur frequently.
Overusing the eyes may exacerbate the symptoms of floaters, so it is better to allow the eyes to rest.
Wishing you peace and good health.
Sincerely, Dr.
Tsai Wen-Yuan, Director of Ophthalmology, Taoyuan General Hospital, Ministry of Health and Welfare.

Post-impact eye injuries can be concerning, especially when they involve trauma to the eye, such as being struck by a fist. While it’s reassuring that your eye examination showed no issues with the retina or the back of the eye, it’s important to understand the potential risks and recovery insights associated with such injuries.

Firstly, it is normal to experience some discomfort or a feeling of pressure in the eye following an impact. This sensation can be attributed to various factors, including inflammation or minor trauma to the surrounding tissues. However, if the pain persists or worsens, it is crucial to follow up with your eye care professional.

Regarding your concerns about potential long-term effects, such as increased astigmatism or a rise in floaters (myodesopsia), these can occur but are not guaranteed. Astigmatism can develop due to changes in the cornea or lens shape, which may be influenced by trauma. However, if your eye doctor has confirmed that your cornea and lens are intact, the likelihood of significant changes in astigmatism is reduced.
As for floaters, they are often a result of the natural aging process of the eye, where the vitreous gel inside the eye begins to liquefy and form clumps. Increased screen time can exacerbate the perception of floaters, as prolonged focus on screens can lead to eye strain. If you notice an increase in floaters, it is advisable to monitor them. If they become more numerous or are accompanied by flashes of light or a shadow in your vision, you should seek immediate medical attention, as these could indicate more serious conditions like retinal detachment.

In terms of recovery, rest is essential. Taking breaks from screens and ensuring you practice good eye hygiene can help alleviate symptoms. The 20-20-20 rule is a helpful guideline: every 20 minutes, look at something 20 feet away for at least 20 seconds. This practice can reduce eye strain and may help with the discomfort you are experiencing.

Additionally, if you have a history of laser eye surgery, it’s important to communicate this to your eye care provider, as they can tailor their assessments and recommendations based on your specific ocular history.
In summary, while your initial examination is reassuring, it’s important to remain vigilant about any changes in your vision or discomfort. Regular follow-ups with your eye care professional will help ensure that any potential complications are addressed promptly. Remember to prioritize rest and eye care practices, especially if you are spending significant time on the computer. If you have ongoing concerns about your symptoms or the impact of your injury, don’t hesitate to seek further evaluation.
