When to Seek Eye Care: Symptoms of High Myopia - Ophthalmology

Timing for Seeking Medical Attention


Hello Doctor: I have high myopia and about a year ago, I experienced flashes of light, which led to a diagnosis of posterior vitreous detachment.
During that period, I underwent several follow-up examinations of the fundus, which showed no issues, and I received some preventive laser treatment.
However, since then, I still occasionally see flashes of light (lasting for a second, occurring several times a day, but sometimes I may not experience them for a while).
Each time I see a flash, I worry about retinal detachment, so I visit the clinic whenever I can.
However, I feel that my follow-up visits have become somewhat frequent (especially since each visit requires dilation, which takes a lot of time).
I'm starting to struggle with whether I need to see a doctor every time I experience a flash.
I would like to ask for your advice, thank you!

If your flash frequency or location has not significantly increased or changed, it is recommended to follow up with an examination in 3 to 6 months.

When it comes to high myopia, or severe nearsightedness, understanding when to seek eye care is crucial for maintaining eye health and preventing serious complications. High myopia can lead to various ocular issues, including retinal detachment, glaucoma, and other vision-threatening conditions. Given your history of experiencing flashes of light and the diagnosis of posterior vitreous detachment, it's understandable that you are concerned about your eye health.

Flashes of light, or photopsia, can occur when the vitreous gel that fills the eye pulls on the retina. In high myopia, the eye is often elongated, which increases the risk of vitreous detachment and retinal tears or detachment. While occasional flashes may not always indicate a serious problem, they should not be ignored, especially in someone with a history of vitreous detachment. If the flashes are accompanied by an increase in floaters, a shadow or curtain over your vision, or a sudden decrease in vision, you should seek immediate medical attention.

In your case, since you have already been diagnosed with posterior vitreous detachment and have undergone preventive laser treatment, it is essential to monitor your symptoms closely. If the flashes persist or worsen, or if you experience any new symptoms, it would be prudent to return to your eye care provider for a thorough examination. Regular follow-ups are important, especially in the first few months after a diagnosis of vitreous detachment, as this is when complications are most likely to occur.

Regarding your concern about the frequency of visits, it is a balancing act between peace of mind and the necessity of monitoring your condition. If your eye care provider has advised you to return for follow-ups, it is likely because they want to ensure that any potential issues are caught early. However, if you feel that the frequency of visits is excessive and you are not experiencing any new or worsening symptoms, it may be worth discussing this with your eye doctor. They can provide guidance on how often you should be seen based on your specific situation and risk factors.

In summary, while occasional flashes of light may not always indicate a serious issue, given your history of high myopia and posterior vitreous detachment, it is essential to remain vigilant. If you notice any changes in your symptoms or if the flashes become more frequent or bothersome, do not hesitate to seek care. Regular eye examinations and open communication with your eye care provider are key to managing your condition effectively and ensuring your long-term eye health.
