Supposing that i just have eye floaters does that mean i have a retinal detachment?

Unlikely : Floaters in the eye have several causes. The most common cause is degeneration of the vitreous fluid. The floaters gradually get worse, and persist. Sudden increase in floaters may be caused by vitreous separation (detachment) and may associated with a retinal tear or detachment, and eye exam is advisable. In both of these situations, the floaters persist.

Visualizing floaters: Increases the risk of retinal pathology. Flashes of light visualized in a dark environment can indicate vitreous (gel-like substance inside eye) traction (pulling) on the retina. At worst it may indicate a retinal tear, break or detachment. At best, it is a vitreous detachment that may be benign (harmless). Confirm your symptoms with your ophthalmologist.
