What causes to see like a flash

Dr. Rick :

Hi. I'm online and happy to answer your question today.

Dr. Rick :

Can you tell me a little bit more about this flash. Is it in one eye only? Is it like a lightning flash or kinda like a shimmering veil?

Customer:

It is only on one eye and it ocurs sudenly, sometimes two or three times in one minute and then nothing. It is like a lighting flash.

Dr. Rick :

Ok.....got it....

Dr. Rick :

You are likely experiencing a PVD or posterior vitreous detachment, a common event that happens in many people.

You have a thick gel material in the middle of your eyes called the vitreous. Over time as it liquefies, this gel material collapses on itself, forms little clumps that you can see as dots, lines or bugs. As these clumps form the vitreous pulls away from the wall of the eye. In the process it can stimulate the retina -- causing the flashes that you may see.

It is recommended that you see your ophthalmologist to look at the retina to make sure there are no problems such as a retinal hole or tear. In most cases, there are no problems, but this exam is precautionary and allows for preventative treatment of any lesions that are found.

If you notice a sudden increase in floaters, flashes of light (like a lightning storm), or a shadow/veil in the periphery of your vision, this can be worrisome for a retinal detachment. You would need to contact your ophthalmologist promptly in that case.
