Resolved Question:

I have occasional brief flashes of light to the far left of my left eye. No pain, just a scratchy feeling in my eye. This started yesterday and seems to be associated with movement of my head--that is it doesn't happen while I am still.

Dr. Rick :

It sounds like you may be having a posterior vitreous detachment.

Expert:  Dr. Rick replied 5 years ago.
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.

Does this make sense to you?
