Retinal Issues: High Myopia and Pigment Deposits Explained

Q: Retinal Issues: High Myopia and Pigment Deposits Explained

Hello, Ms. Wang： 1. It can sometimes be spontaneous. 2. Retinitis pigmentosa is one of the characteristics of night blindness, but individuals with retinitis pigmentosa may not always experience night blindness. 3. It is possible that there is a pre-existi

Retinal-related issues?

1.
Is retinal pigment deposition congenital?
2.
If there is pigment deposition in the retina but no night blindness or other discomfort, does this indicate that the eyes are healthy?
3.
With retinal pigment deposition but no night blindness, will there be differences compared to others? For example, if two individuals both have myopia of -6.00 diopters, can the one without pigment deposition see more clearly after correction, while the one with pigment deposition may see but not as clearly? Is this a possible scenario?
4.
Can retinal thinning be maintained at its current state, meaning it won't continue to worsen, or will it inevitably become thinner? Additionally, what symptoms might occur before retinal holes or detachment? Thank you, doctor! I apologize for continually bothering you.

Hello, Ms.
Wang: 1.
It can sometimes be spontaneous.
2.
Retinitis pigmentosa is one of the characteristics of night blindness, but individuals with retinitis pigmentosa may not always experience night blindness.
3.
It is possible that there is a pre-existing difference in vision that is not necessarily related to pigmentary degeneration.
4.
Thinning is irreversible, and if there is a risk of a tear, laser treatment may be performed as a preventive measure.
When a tear occurs, one may see shadows or an increase in flashes of light, and in severe cases, there may be visual field loss.

Understanding retinal issues, particularly in the context of high myopia, is crucial for maintaining eye health and preventing potential complications. Let's address your questions regarding retinal pigment deposits and their implications.

1. Are retinal pigment deposits congenital?
Retinal pigment deposits can be congenital, meaning they may be present from birth due to genetic factors. However, they can also develop later in life due to various reasons, including aging, high myopia, or other retinal diseases. In high myopia, the structure of the eye changes, which can lead to alterations in the retinal pigment epithelium, resulting in pigment deposits.

2. If there are pigment deposits without night blindness or other discomfort, does this indicate healthy eyes?
The presence of retinal pigment deposits alone does not necessarily indicate poor eye health, especially if you are not experiencing symptoms like night blindness or visual disturbances. However, it is essential to have regular eye examinations to monitor any changes in the retina, as the absence of symptoms does not guarantee that the retina is free from underlying issues.

3. Can retinal pigment deposits affect visual clarity compared to those without deposits?
Yes, retinal pigment deposits can potentially affect visual clarity. While individuals with similar degrees of myopia may have different visual outcomes based on the presence of pigment deposits, those without such deposits might experience clearer vision. This is because pigment deposits can interfere with the normal functioning of the retina and may affect how light is processed, leading to variations in visual acuity.

4. Can retinal thinning remain stable, or will it continue to worsen? What are the symptoms before retinal holes or detachment?
Retinal thinning is a common concern in high myopia and can progress over time. While some individuals may experience stable conditions, others may see continued thinning, which can increase the risk of retinal tears or detachment. Symptoms that may precede retinal holes or detachment include sudden flashes of light, an increase in floaters, or a shadow or curtain effect in the peripheral vision. If you notice any of these symptoms, it is crucial to seek immediate medical attention.

In summary, while retinal pigment deposits can be congenital and may not always indicate poor eye health, they can influence visual clarity. Regular eye check-ups are essential for monitoring retinal health, especially in individuals with high myopia. Maintaining a proactive approach to eye care, including understanding the potential risks associated with retinal thinning and being aware of warning signs, can help preserve vision and overall eye health. If you have any concerns or notice changes in your vision, do not hesitate to consult with your eye care professional for further evaluation and guidance.
