One of the most common complaints our patients have is flashes and/or floaters. There are many reasons for these symptoms, but the most common is a posterior vitreous detachment or PVD.
The vitreous humor lies between the lens and the retina. Early in life, the vitreous is a jelly-like substance. With age, the jelly-like substance begins to liquefy. This causes vitreous syneresis, one cause of vitreous floaters.
The vitreous is attached to the retina at the optic nerve, the macula, and the peripheral retina. During the liquefication process, the vitreous begins to pull on the retina. The pulling, or traction, on the retina creates flashing which is usually seen by the patient as a bright arc in the temporal visual field.
When the vitreous pulls away from the retina, it is known as a posterior vitreous detachment. Usually this occurs without any consequences for the patient except for pesky floaters. However, it can lead to a retinal tear or detachment. Retinal tears and detachments can be treated but should be addressed quickly. Therefore, we recommend that all patients with new floaters should be seen by an Optometrist or Ophthalmologist.
