Hello! It sounds like you are experiencing persistent eye flashes, which can indeed be concerning, especially given your history of high myopia and previous eye issues. First, let’s discuss what eye flashes are and why they might occur.

Eye flashes, or photopsia, are often described as brief bursts of light that can appear in your field of vision. They can be caused by various factors, including vitreous detachment, retinal tears, or even migraines. In individuals with high myopia, the risk of these conditions can be higher due to the elongation of the eyeball, which can lead to changes in the vitreous gel and the retina.

Since you have been experiencing these flashes for nearly a year and have noticed an increase in their frequency or intensity, it is essential to follow up with your eye care provider. Here are some tests and evaluations that may be recommended:
1. Dilated Fundus Examination: This is a critical test where the eye doctor uses special drops to widen your pupils and then examines the retina and vitreous for any abnormalities. Since you have already undergone this test, it’s important to ensure that the doctor thoroughly checked for any signs of retinal tears or detachment.

2. Optical Coherence Tomography (OCT): This non-invasive imaging test provides cross-sectional images of the retina, allowing the doctor to see the layers of the retina and any potential issues, such as thinning or swelling. It can also help assess the vitreous and its relationship with the retina.

3. Ultrasound of the Eye: If there are concerns about the retina that cannot be visualized clearly through the dilated examination, an ultrasound can provide additional information about the vitreous and retina.

4. Visual Field Testing: This test assesses your peripheral vision and can help determine if there are any areas of vision loss that might correlate with the flashes you are experiencing.

5. Amsler Grid Test: This simple test can help you monitor for any distortion or changes in your central vision, which could indicate issues with the macula or retina.

Given your history of macular bleeding, it is also wise to keep an eye on any changes in your vision and report them to your doctor. If the flashes are accompanied by other symptoms such as new floaters, a shadow in your vision, or a sudden decrease in vision, you should seek immediate medical attention.

In terms of management, if your eye doctor determines that the flashes are due to benign causes, they may suggest monitoring the situation rather than immediate intervention. However, if there are signs of retinal issues, they may discuss treatment options, which could include laser therapy if necessary.

Lastly, it’s essential to manage any anxiety or stress related to your eye health. Stress can exacerbate visual symptoms and overall well-being. Make sure to maintain regular follow-ups with your eye care provider and communicate any new or worsening symptoms promptly.

In summary, persistent eye flashes warrant thorough evaluation, especially in the context of high myopia and previous eye conditions. Regular monitoring and appropriate testing will help ensure that any potential issues are addressed promptly. If you have further concerns or if symptoms worsen, do not hesitate to reach out to your eye care professional. Your eye health is paramount, and staying proactive is the best approach.
