Having very small occasional flashes(if i try to move my eyes vigorously in complete dark).got an appointment only next week.is the waiting time fine?

Flashes of light: Seen in a dark environment only 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). Visualizing floaters or blurred vision in any quadrant heightens the risk of retinal pathology. Confirm your symptoms with the office for urgency.

Probably, but..: Flashes in one eye happen when the vitreous gel pulls on the retina as it separates from the eye walls. This can cause retinal detachment. I would be more concerned if you have a family history of detachment or tears. Look for more floaters or a shadow or curtain. Be aware of any changes in vision and let your eye specialist know and they may move you up. Tears can be lasered in the office.
