Poor vision with the perception of light spots?


Dr.
Kao: Hello! I have two questions for you:
1.
My left eye has a prescription of -3.50 diopters (corrected to 20/16), and my right eye has a prescription of -13.00 diopters (corrected to 20/30, but not very clear with some double vision).
Currently, my glasses have a prescription of -3.50 for the left eye and -9.50 for the right eye.
My right eye's vision is very poor, and I cannot see clearly.
I am considering not increasing the prescription for the right eye further due to the significant difference in lens power between the two eyes.
I visited an ophthalmology clinic, and the doctor informed me that cataracts are the cause, with the right eye being more severely affected, but it has not yet reached the surgical threshold for cataract removal.
The doctor suggested monitoring the situation.
Are there any other options available?
2.
I have a long-standing history of dry eyes and floaters.
About two months ago, I started experiencing light spots (in both eyes) that move in circles around the eyeball, with varying directions and a slow speed, lasting about two seconds before disappearing.
The light spots usually appear as one point, sometimes two points moving in different directions.
About two weeks ago, I underwent a fundus examination, and the doctor only mentioned that the retina is normal, with slight degeneration of the macula.
Recently, the frequency of these light spots has increased, and I am somewhat concerned.
Should I consider further examination? Thank you!

Hello, Qi-An:
1.
If the disparity in vision is caused by cataracts, it is advisable to manage it temporarily.
However, if it causes significant inconvenience, considering cataract extraction may be an option.
2.
If you have undergone a fundus examination and the physician has stated that the retina is normal, there is no need for excessive concern; you can continue to monitor your condition.
Puzih Hospital Ophthalmology Department in Taiwan: Monday to Friday from 8:00 AM to 12:00 PM, and Wednesday from 1:00 PM to 4:30 PM.
Please note that online responses are for reference only; it is essential to seek care at a medical facility if necessary.
I hope to have the opportunity to serve you.

Hello! Thank you for your questions regarding your eye health concerns. Let's address each of your inquiries in detail.

1. White Cataract and Vision: You mentioned that you have significant differences in your prescription between your left and right eyes, with the right eye being particularly poor in vision due to cataracts. It’s important to understand that cataracts can indeed cause blurred vision and double vision, especially when they are more advanced. Since your eye doctor has advised you to monitor the situation, it’s crucial to follow their guidance. However, if you find that your quality of life is significantly impacted by your vision, you might want to discuss the possibility of cataract surgery sooner rather than later. Cataract surgery is one of the most common and successful procedures performed, and it can greatly improve your vision. Additionally, you could explore options such as specialized contact lenses or glasses that may help with the disparity in vision between your eyes, but these should be discussed with your eye care professional.

2. Visual Disturbances and Light Spots: The appearance of light spots or flashes in your vision, especially given your history of dry eyes and floaters, can be concerning. These light spots could be related to several factors, including the vitreous gel in your eye pulling away from the retina, which is common as we age. However, since you have noticed an increase in frequency and have a history of eye issues, it is advisable to seek further evaluation. While your recent eye exam indicated that your retina is normal, persistent changes in your vision warrant a thorough examination. You might consider asking for a more detailed assessment, such as a dilated fundus exam or optical coherence tomography (OCT), which can provide more information about the health of your retina and the vitreous.

Additional Considerations: Given your history of dry eyes and floaters, it’s also essential to manage these conditions effectively. Dry eyes can exacerbate visual disturbances, so using lubricating eye drops regularly can help alleviate some discomfort. Additionally, maintaining a healthy lifestyle, including proper hydration, a balanced diet rich in omega-3 fatty acids, and regular eye check-ups, can contribute to better eye health.

Psychological Impact: It’s understandable that these visual disturbances can cause anxiety and concern. The mind and eyes are closely linked, and stress can sometimes exacerbate visual symptoms. If you find that your anxiety is affecting your daily life, consider discussing this with a healthcare provider who can offer support or strategies to manage your stress.

In summary, while your current situation may not require immediate intervention, it is essential to stay vigilant and maintain regular communication with your eye care provider. If your symptoms worsen or you have new concerns, do not hesitate to seek further evaluation. Your eye health is paramount, and proactive management can help preserve your vision and overall well-being.
