Macular degeneration

Hello Doctor, I just turned twenty this year.
I have myopia in both eyes, with prescriptions of -4.25 and -4.75 diopters.
Just tonight, I noticed while looking at the Amsler grid that the lines appeared straight at first, but after about five seconds, some of the straight lines started to look wavy, as if they were drawn by hand with a shaky line.
After blinking, when I opened my eyes, everything looked normal again, but then it became slightly wavy again.
When I looked with both eyes, the lines appeared straight.
Could this be a sign of macular degeneration, or is it possibly due to eye fatigue? Thank you, Doctor.

Hello: Based on your description, the sudden visual changes in your eyes under specific circumstances may have multiple causes.
Firstly, the situation you described could be due to eye fatigue or ocular strain, especially when focusing on near objects.
Prolonged use of electronic devices, reading, or other near-vision activities can lead to eye fatigue, which may manifest as blurred or distorted vision.
Alternatively, dry eyes can result in an incomplete tear film, causing abnormal light refraction.
However, if there is macular degeneration, objects will appear distorted and will not return to normal; if the vision quickly recovers, it is likely not macular degeneration.
I recommend that you see an ophthalmologist as soon as possible for a thorough examination, including an assessment of the macula and other ocular structures.
Only a physician can provide a definitive diagnosis after a detailed examination.

Understanding macular degeneration is crucial, especially for someone like you who is experiencing visual disturbances. Macular degeneration, particularly age-related macular degeneration (AMD), is a condition that affects the macula, the central part of the retina responsible for sharp, detailed vision. However, given your age and the symptoms you described, it is more likely that you are experiencing a temporary visual phenomenon rather than macular degeneration.

The symptoms you mentioned—seeing straight lines appear wavy or distorted—can be indicative of a few different conditions. One possibility is a visual phenomenon known as metamorphopsia, which is often associated with retinal issues. In younger individuals, this can be caused by a variety of factors, including eye strain, migraines, or even transient visual disturbances that may not be related to any underlying disease.

Given that you are only twenty years old and have significant myopia (nearsightedness), it is essential to consider that high myopia can lead to changes in the retina over time, including the potential for retinal tears or detachments. However, these conditions typically present with more severe symptoms, such as flashes of light or a sudden increase in floaters, rather than the temporary distortion you described.

Another potential cause of your symptoms could be related to eye fatigue, especially if you have been using screens or reading for extended periods. Eye strain can lead to temporary visual disturbances, including blurred vision or distortion. Taking regular breaks and practicing the 20-20-20 rule—looking at something 20 feet away for 20 seconds every 20 minutes—can help alleviate these symptoms.

If your symptoms persist or worsen, it is crucial to consult with an eye care professional. They can perform a comprehensive eye examination, including a dilated fundus exam, to assess the health of your retina and macula. Early detection of any potential issues is vital for preserving your vision, especially if there are underlying conditions that need to be addressed.

In summary, while your symptoms could be concerning, they are not definitively indicative of macular degeneration, especially given your age. It is more likely that they are related to eye strain or a temporary visual phenomenon. However, it is always best to err on the side of caution and seek professional advice to ensure your eyes remain healthy. Regular eye exams are essential, particularly for individuals with myopia, to monitor for any changes in eye health over time.
