Eye doctors around the world frequently examine people for a chief complaint of floaters. Patients describe a wide variety of symptoms, usually worsened by bright lighting conditions. The vast majority of patients with eye floaters have a benign condition known as vitreous syneresis in which portions of the normally clear and transparent vitreous jelly inside the eye becomes less transparent. Most eye floaters are caused by small flecks of a protein called collagen.
Patients may describe a wide variety of symptoms, including spiders or insects darting across their vision, cobwebs, dirt on the windshield, spots, strands, black spots in their vision, squiggly lines, and of course floaters. Diagnosis and Treatment: Benign eye floaters almost never require medical treatment. If eye floaters are so dense and numerous that they affect your vision, your eye doctor may consider a surgical procedure called a vitrectomy.
Floaters have been reported in patients as young as 9.They may be of embryonic origin or acquired due to degenerative changes of the vitreous humour or retina. However, floaters in teenage patients and young adults are usually harder to treat. For people in this age group, the floater that is seen usually looks like a kind of crystal (translucent) worm/web/cell. However floaters are extremely common in adults with almost everyone over the age of 70 being affected by it.
