Posterior vitreous detachment is normally present in old ages and also in myopic patients. Usually it occurs without complications and only the patients will complain of floaters which usually will disappear from few weeks to month later. Sometimes, posterior vitreous detachment from the retina is incomplete, in which some parts will remain attached to the retina, causing traction on the retina. This traction will be noticed by the patient as flashes of lights and with time, this traction can lead to retinal detachment.

Note: Any patient who noticed floaters for the first time should have complete ocular examination to rule out any incomplete vitreous detachments with traction on the retina.Other causes of floaters are deposits on the vitreous humor which can occur after uveitis in which white blood cells will deposit, after resolved vitreous hemorrhage in which red blood cells will deposit, after cataract surgery especially when there is posterior capsule rupture, after intraocular injections in which drug remnants will deposit in the vitreous.
