Dark Yellow Vision in High Myopia: Causes and Solutions

Q: Dark Yellow Vision in High Myopia: Causes and Solutions

Hello Krystal： It may be an issue with the retinal photoreceptor cells, and it might be necessary to perform an electroretinogram to assess the functionality of the photoreceptor cells.

The left eye sees things as dark yellow?

I am 25 years old and have high myopia in both eyes: right eye: -950, left eye: -700 (with astigmatism of -2.00 to -2.50 in both eyes).
Both eyes have undergone retinal laser treatment for holes.
My left eye sees things very dimly and with a yellow tint, and there is a significant color difference between the two eyes.
When the light is insufficient, I can hardly see with my left eye, and it is very straining, while my right eye does not have this issue.
I have undergone many examinations and various tests, and the doctors have said there is no significant problem, but I still feel anxious every day, fearing that I might have macular degeneration.
However, in July of last year, the doctor said my macula looked good.
I have been using the Amsler Grid test for macular degeneration, and both eyes appear normal.
I also visit a major hospital for check-ups every three months, but my left eye seems to be getting dimmer than before.
I would like to ask the doctor why this is happening.

More Info

Understanding the phenomenon of dark yellow vision, especially in the context of high myopia, involves a multifaceted approach that considers both the anatomical and physiological aspects of the eye. At 25 years old, with a significant degree of myopia (950 in the right eye and 700 in the left), along with a history of retinal laser treatment, your concerns about visual changes are valid and warrant careful consideration.

Causes of Dark Yellow Vision
1. Retinal Changes: High myopia can lead to various retinal complications, including retinal thinning, lattice degeneration, and even retinal detachment. These changes can affect how light is processed by the retina, potentially leading to altered color perception and brightness. The dark yellow tint you are experiencing could be a result of changes in the retinal pigment epithelium or the photoreceptors, which are responsible for converting light into neural signals.

2. Optical Factors: The presence of astigmatism (200-250 in both eyes) can also contribute to visual distortions. Astigmatism causes light to focus on multiple points in the eye, leading to blurred or distorted vision. This could explain why your left eye is experiencing more difficulty in low-light conditions compared to your right eye.

3. Visual Fatigue: Extended periods of visual strain, particularly from screens or reading, can exacerbate symptoms of visual discomfort. This fatigue can lead to a perception of dimness or color distortion, particularly in individuals with high myopia, as their eyes may be more sensitive to changes in light and contrast.

4. Psychological Factors: Anxiety and stress about your vision can also amplify your perception of visual disturbances. The fear of potential conditions like macular degeneration can lead to hyperawareness of your vision, making you more sensitive to changes that may not be clinically significant.

Solutions and Recommendations
1. Regular Eye Examinations: It is crucial to continue with regular eye check-ups, as you are already doing. These examinations should include comprehensive assessments such as Optical Coherence Tomography (OCT) and visual field tests to monitor any changes in the retina and optic nerve.

2. Amsler Grid Testing: Continue using the Amsler Grid to monitor for any changes in your central vision. This simple test can help detect early signs of macular degeneration or other retinal issues.

3. Visual Hygiene: Implementing good visual hygiene practices can help reduce eye strain. This includes taking regular breaks when using screens (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds), ensuring proper lighting when reading or working, and using anti-reflective coatings on glasses if applicable.

4. Consultation with a Specialist: If your symptoms persist or worsen, consider consulting a retinal specialist. They can provide a more detailed evaluation of your retinal health and discuss potential treatments or interventions if necessary.

5. Lifestyle Modifications: Maintaining a healthy lifestyle, including a balanced diet rich in antioxidants (like vitamins C and E, lutein, and zeaxanthin), can support overall eye health. Regular exercise and adequate sleep are also essential for reducing eye strain and improving overall well-being.

6. Psychological Support: If anxiety about your vision is affecting your quality of life, consider speaking with a mental health professional. They can help you develop coping strategies to manage your concerns.

Conclusion
While your concerns about dark yellow vision and potential retinal issues are understandable, it is essential to approach the situation with a balanced perspective. Regular monitoring and proactive management of your eye health, combined with lifestyle adjustments, can help mitigate symptoms and maintain your vision quality. Always communicate openly with your eye care provider about any changes in your vision, as they can provide tailored advice and reassurance based on your specific circumstances.
