• floaters
  • When this occurs there is a characteristic pattern of symptoms: Flashes of light (photopsia) A sudden dramatic increase in the number of floaters A ring of floaters or hairs just to the temporal side of the central vision As a posterior vitreous detachment proceeds, adherent vitreous membrane may pull on the retina. (wikipedia.org)
  • citation needed] If a retinal vessel is torn, the leakage of blood into the vitreous cavity is often perceived as a "shower" of floaters. (wikipedia.org)
  • In absence of retinal tears, the usual progress is that the vitreous humor will continue to age and liquefy and floaters will usually become less and less noticeable, and eventually most symptoms will completely disappear. (wikipedia.org)
  • Prompt examination of patients experiencing vitreous humor floaters combined with expeditious treatment of any retinal tears has been suggested as the most effective means of preventing certain types of retinal detachments. (wikipedia.org)
  • Ocular asteroids must be distinguished from the more common typical vitreous floaters, which are usually fibrillar or cellular condensates. (wikipedia.org)
  • traction
  • Rhegmatogenous retinal detachment is characterized by the presence of a retinal break held open by vitreoretinal traction, which allows the accumulation of liquefied vitreous under the neurosensory retina, separating it from the retinal pigment epithelium (RPE). (arvojournals.org)
  • While there are no pain fibers in the retina, vitreous traction may stimulate the retina, with resultant flashes that can look like a perfect circle. (wikipedia.org)
  • occur
  • The risk of retinal detachment is greatest in the first 6 weeks following a vitreous detachment, but can occur over 3 months after the event. (wikipedia.org)
