Hello,

Thank you for the question.

Flashes of light can occur due to a pull or a traction on the retina. This can occur with posterior vitreous detachment(PVD), Retinal detachment(RD) , Vitreomacular tractional bands, migraine and other conditions. PVD is characterized by a sudden bout of flashes of light with floaters. However it does not cause any loss of vision except some fogginess in the area of floater. Whereas in case of RD, apart from flashes and floaters there is blurring of vision in one or more part of the visual field as if looking through a veil or curtain. If you are experiencing only flashes and no visual loss, then it is most likely to be due to PVD. This can be diagnosed by an ophthalmologist following a dilated eye exam. Usually it does not require any further treatment. I guess you can observe the eye for any new symptoms or any visual disturbance such as mentioned above and take an appointment with your ophthalmologist. If there are no other eye symptoms then you can just wait and watch.
