Flashes of Light When Turning with Eyes Closed: Should You Worry? - Ophthalmology

Experiencing flashes of light when turning your head with your eyes closed can be concerning, especially if you have a history of retinal issues, such as a retinal tear that has formed a scar. It’s important to understand the nature of these flashes and when they warrant further medical evaluation.

Flashes of light, or photopsia, can occur for various reasons. In many cases, they are benign and related to the vitreous gel in the eye pulling away from the retina, which is common as we age. However, since you mentioned having a retinal tear, it is crucial to be vigilant about any new or changing symptoms. Flashes can sometimes indicate that the vitreous is exerting traction on the retina, which could lead to further complications, including retinal detachment.

Given your recent history of a retinal tear, it is advisable to err on the side of caution. If the flashes are new, persistent, or accompanied by other symptoms such as a sudden increase in floaters, a shadow or curtain effect in your vision, or any significant changes in your visual field, you should seek immediate evaluation by an eye care professional. These symptoms could indicate that the condition of your retina has changed and may require intervention.

In your specific case, since you experienced flashes only when turning your head and they disappear quickly, it may be related to the mechanical movement of the eye and the surrounding structures rather than a direct retinal issue. However, the fact that you have a known history of retinal problems makes it essential to monitor these symptoms closely.

Regarding whether you need another eye exam, if the flashes are isolated and not accompanied by other concerning symptoms, you might choose to observe them for a short period. However, if they persist or worsen, or if you experience any new symptoms, it would be prudent to schedule a follow-up appointment with your ophthalmologist. They can perform a thorough examination, including a dilated fundus exam, to assess the health of your retina and ensure that there are no new developments.

In the meantime, try to avoid activities that may strain your eyes or put you at risk for further injury. This includes avoiding heavy lifting or vigorous physical activity that could increase intraocular pressure or cause sudden movements of the vitreous. Additionally, managing stress and ensuring you get adequate rest can help alleviate some anxiety related to your symptoms.

In summary, while flashes of light can be a common occurrence, your history of retinal issues necessitates a cautious approach. If in doubt, it’s always best to consult with your eye care provider to ensure your eyes remain healthy and to address any concerns you may have. Regular monitoring and communication with your healthcare provider are key to managing your eye health effectively.
