Flashing Lights in Vision: When to Seek Eye Care - Ophthalmology

More Info

---

Flashing lights in vision can be a concerning symptom, especially for individuals with a history of eye issues or those who are highly myopic. Based on your description, it seems you have been experiencing these flashes intermittently since November of last year, and while you had an examination in January that showed no significant issues, the recurrence of these symptoms warrants further discussion.

1. Understanding Flashing Lights: The flashes you describe, particularly when you close your eyes and focus on a point in the dark, could indeed be related to vitreous changes in the eye. As we age or due to certain conditions, the vitreous gel that fills the eye can begin to liquefy and pull away from the retina, which can lead to sensations of flashing lights or "photopsia." This phenomenon is often benign, especially if there are no accompanying symptoms such as a sudden increase in floaters, a shadow in your vision, or a loss of peripheral vision. However, it is essential to monitor these symptoms closely.

2. When to Seek Care: While your previous examination did not reveal any issues, the appearance of new symptoms, especially after a period of relief, should not be ignored. If the flashes become more frequent, intense, or are accompanied by other visual disturbances, it is advisable to seek an eye care professional's opinion sooner rather than later. Given your history of flashes and the potential for vitreous detachment or retinal issues, a proactive approach is warranted.

3. Vitreous Detachment and Retinal Health: The phenomenon of seeing flashes when moving your head or eyes, particularly in low light, can be indicative of vitreous traction on the retina. This is not uncommon, especially in individuals with high myopia, as the retina may be thinner and more susceptible to changes. If you notice that these flashes are persistent or if they change in nature, such as becoming more pronounced or accompanied by other symptoms, it would be prudent to schedule an eye examination sooner than your planned visit in June.

4. Light Flashes and Visual Disturbances: The light flashes you experience when turning your head could also be related to the same vitreous changes. The sensation of seeing light flashes when moving your head is often due to the vitreous tugging on the retina. If these flashes are brief and resolve quickly, they may not be a cause for immediate concern. However, if they persist or are associated with other symptoms, it is essential to consult with an eye care professional.

5. Conclusion and Recommendations: In summary, while some flashing lights can be benign, your history and the recurrence of symptoms suggest that it would be wise to have a follow-up examination sooner than your scheduled appointment in June. This is especially true if you notice any changes in your vision or the nature of the flashes. Regular monitoring and communication with your eye care provider are crucial in managing your eye health, particularly with your myopic condition. If you experience any sudden changes in your vision, do not hesitate to seek immediate medical attention. Your eye health is paramount, and staying vigilant can help prevent potential complications.
