Floaters are small spots in the vision due to cells or opacities in the vitreous gel that cast a shadow on the retina. Floaters often move and come in all different sizes and shapes, including dots, circles, lines, or cobwebs. Floaters usually develop during a posterior vitreous separation when the vitreous gel begins to shrink and pull away from the retina. Alternatively, new floaters can be due to a vitreous hemorrhage (bleeding in the vitreous). Retinal tears and advanced diabetic retinopathy are often the cause of this condition, although many other retinal conditions can lead to vitreous hemorrhage and floaters. Any patient with sudden new onset of floaters should have their retina examined to determine the cause and ensure that proper treatment is initiated.
