Other problems can occur when the fluid that fills the inner cavity of the eye (vitreous fluid) begins to shrink. Flashes appear as flashing lights or lightning streaks in the field of vision, although no light is actually flashing. These are most often noticed at night or in a dark room and can be a sign of retinal detachment.
Floaters can cause dots or lines, or appear to be cobwebs or clouds in the field of vision. They are formed from the reorganization of the vitreous material or by bleeding.
Although they are usually just an annoyance, floaters and flashes may be signs of a retinal tear or detachment. Our Retina Specialists will perform a thorough exam to determine if they require treatment. Surgery is rarely indicated, except when the floaters obscure the vision or when they or flashes are related to a serious problem.
