Sudden Vision Symptom Evaluation

New floaters, flashes, or a shadow in vision can sometimes indicate a retinal tear or detachment.
Floaters are small specks, dots, threads, or cobweb-like shadows that appear to move through the field of vision. They often come from tiny clumps in the vitreous, the clear gel inside the eye.
Flashes can happen when the vitreous tugs on the retina. This is more common with age as the vitreous changes and separates from the back of the eye, a process called posterior vitreous detachment.
A sudden shower of new floaters, repeated flashes, decreased side vision, or a curtain-like shadow can indicate a retinal tear or retinal detachment. These symptoms should be checked promptly because early treatment can reduce the risk of permanent vision loss.
