Symptoms of Retinal Tears: When to Seek Eye Care for Flashing Lights - Ophthalmology

More Info

Retinal tears can be a serious condition that may lead to retinal detachment if not addressed promptly. Given your history of high myopia (over 600 degrees) and the presence of floaters, it is crucial to be aware of the symptoms associated with retinal tears and when to seek medical attention.


Symptoms of Retinal Tears
1. Flashing Lights: One of the most common symptoms of retinal tears is the perception of flashing lights in your vision. This phenomenon occurs when the vitreous gel inside the eye pulls on the retina, causing it to send signals to the brain that are interpreted as flashes of light. The flashes can vary in intensity and may appear as brief bursts of light or more sustained flashes.

2. Floaters: You mentioned experiencing floaters, which are small specks or cobweb-like shapes that drift across your field of vision. While floaters are common and often benign, a sudden increase in floaters, especially if accompanied by flashes of light, can indicate a potential retinal tear.

3. Curtain or Shadow Effect: If you notice a shadow or curtain-like effect in your peripheral vision, this could be a sign of a more serious condition, such as retinal detachment. This symptom warrants immediate medical attention.

4. Blurred Vision: Changes in your vision, such as blurriness or a decrease in visual acuity, can also be associated with retinal tears. If you experience sudden changes in your vision, it is essential to seek care.

5. Visual Distortions: You mentioned that your flashes are not in the form of lightning but rather a brief illumination. This can still be a sign of retinal irritation or traction, especially if it occurs with eye movement.


When to Seek Eye Care
Given your current symptoms—flashing lights with eye movement and a history of myopia and floaters—it is advisable to seek an eye care professional's opinion. Here are some guidelines on when to seek care:
- Sudden Onset of Symptoms: If you experience a sudden increase in flashes or floaters, or if you notice any new visual disturbances, you should see an eye doctor as soon as possible.

- Persistent Symptoms: If the flashing lights persist or worsen, even if they are not accompanied by other symptoms, it is prudent to have a thorough examination.

- Changes in Vision: Any changes in your vision, such as blurriness or the appearance of shadows, should prompt an immediate visit to an eye care professional.

- Regular Monitoring: Since you have a history of high myopia and floaters, regular eye examinations are essential. Even if previous checks showed no retinal tears, changes in your symptoms can occur, and ongoing monitoring is crucial.


Conclusion
In summary, while flashing lights can be a benign symptom, in the context of your high myopia and floaters, they could indicate a retinal tear or other serious condition. It is always better to err on the side of caution when it comes to eye health. I recommend scheduling an appointment with an ophthalmologist for a comprehensive eye examination, including a dilated fundus exam, to assess the health of your retina and rule out any potential issues. Early detection and treatment are key to preserving your vision and preventing complications.
