Dear Mr. Hsiao,
Thank you for reaching out with your concerns regarding your eye health. I appreciate your detailed description of the symptoms you are experiencing, which will help in understanding your situation better. Let’s address your questions one by one.

1. Visual Phenomena with Light Exposure: The appearance of vertical lines or rainbow-like colors when looking at bright surfaces, such as a white wall under sunlight or fluorescent lights, can be indicative of several conditions. One possibility is that you are experiencing visual disturbances known as "visual snow" or "entoptic phenomena," which can occur due to various reasons, including migraines or retinal issues. However, it is essential to rule out any retinal problems, such as retinal detachment or macular degeneration, especially if these symptoms are new or have changed in intensity. I recommend scheduling a comprehensive eye examination, including a dilated fundus exam, to assess the health of your retina.

2. Seeing Black Spots or Bright Points: The phenomenon of seeing black spots or bright points when looking at headlights or streetlights, especially at night, could be related to several factors. This could be a result of "floaters," which are small clumps of gel or cells inside the vitreous that cast shadows on the retina. However, if these spots are accompanied by flashes of light or a sudden increase in floaters, it could indicate a more serious condition, such as a retinal tear or detachment. The fact that you see bright points when your eyes are closed suggests that this may be related to the way your visual system processes light. Again, a thorough examination by an eye care professional is crucial to rule out any significant retinal issues.

3. Retinal Diseases and Treatment Options: Retinal diseases can vary widely in their nature and severity. Some conditions, like diabetic retinopathy or age-related macular degeneration, can be managed effectively with treatments such as laser therapy, injections, or surgery, but they may not always restore vision to pre-disease levels. The prognosis often depends on the specific condition, the extent of damage, and how early it is detected. While some retinal issues may not be completely curable, many can be managed to prevent further deterioration of vision. It is essential to have regular check-ups and follow your eye care provider's recommendations to monitor your condition.

In summary, your symptoms warrant a thorough evaluation by an eye care professional. Early detection and intervention are key in managing retinal issues effectively. I encourage you to seek an appointment with an ophthalmologist who can provide a comprehensive assessment and discuss potential treatment options tailored to your specific needs.

Please take care of your eye health, and do not hesitate to reach out if you have further questions or concerns.
