Macular Issues: When to Seek Eye Care - Ophthalmology

Macular issues


I would like to consult a doctor.
My eyesight is approximately -4.00 diopters in both eyes, and I have floaters in my right eye but not in my left.
Recently, I used an Amsler grid with a white background and black lines to check my vision and noticed that the lower left part of my visual field in my left eye sometimes appears slightly blurry, and the lines seem to waver.
After blinking, it sometimes returns to normal.
I then tried an Amsler grid with a black background and white lines, and I did not experience this issue; my visual field appeared normal.
Should I consider getting an examination?

Hello, Kang Kang: This is likely a phenomenon of floaters.
Macular degeneration does not resolve with a blink, so it should not be the case.
You may continue to observe it yourself.

When it comes to understanding macular issues, especially when you notice changes in your vision, it is crucial to take these symptoms seriously. The macula is a small area in the retina responsible for central vision, and any disturbances can lead to significant visual problems. Given your situation, where you have myopia in both eyes and are experiencing symptoms such as floaters in your right eye and occasional blurriness in the lower left field of your left eye, it is advisable to seek professional eye care.

The fact that you have noticed changes while using the Amsler grid is particularly noteworthy. The Amsler grid is a valuable tool for detecting potential macular problems, such as macular degeneration or other retinal issues. The symptoms you describe—blurriness and distortion of lines—can indicate a problem with the macula, even if it temporarily resolves after blinking. This could suggest transient changes in your vision, possibly due to factors like eye fatigue, dry eyes, or even early signs of macular degeneration.

Here are some key points to consider regarding your symptoms and when to seek eye care:
1. Persistent Symptoms: If you experience any persistent changes in your vision, such as blurriness, distortion, or new floaters, it is essential to consult an eye care professional. While some symptoms may resolve temporarily, ongoing issues warrant a thorough examination.

2. Risk Factors: You mentioned having myopia, which can increase the risk of retinal issues, including retinal tears or detachment. Additionally, age, family history, and other health conditions can also contribute to the risk of macular problems. If you have any of these risk factors, it is even more critical to have regular eye exams.

3. Comprehensive Eye Exam: A comprehensive eye exam will allow an eye care professional to assess your overall eye health, including the condition of your retina and macula. They may perform additional tests, such as optical coherence tomography (OCT) or fundus photography, to get a clearer picture of your retinal health.

4. Changes in Visual Patterns: The fact that changing the background of the Amsler grid affected your perception of the lines could indicate that your visual system is responding differently under varying conditions. This could be related to contrast sensitivity, which is often affected in individuals with macular issues.
5. Follow-Up: If you have already had an eye exam recently, but your symptoms have changed, it is advisable to follow up with your eye care provider. They can determine if further evaluation is necessary or if any treatment is required.

In conclusion, while some visual disturbances can be benign, your symptoms suggest that it would be prudent to seek an eye care professional's opinion. Early detection and intervention are key to managing potential macular issues effectively. Regular eye exams are essential, especially as you age or if you have risk factors for eye diseases. Don't hesitate to reach out to an eye care specialist to discuss your symptoms and get the appropriate care.
