![]() These are often dark specks, globs, strings, or small moving spots that appear in your field of vision. These flashes, which usually appear at the edge of your visual field, occur when the vitreous gel tugs on the retina (vitreous traction).įloaters: Floaters are thick strands or clumps of solid vitreous gel that develop as the gel ages and breaks down. What are the signs and symptoms of retinal detachment?įlashing lights: Flashes of light or sparks may be experienced when you move your eyes or head. A retinal detachment can also be caused by an injury to your eye or a previous eye surgery. Fluid then collects under the retina, causing it to separate. You may notice ëfloatersí or flashing lights. Most retinal detachments are caused by this jelly shrinking and pulling on the retina, causing a small hole or tear. Jelly (called vitreous) fills the centre of your eye. What are the causes of retinal detachment? 1) A rhegmatogenous retinal detachment occurs due to a break in the retina (called a retinal tear) that allows fluid to pass from the vitreous space into the subretinal space, between the sensory retina and the retinal pigment epithelium, and lifting the retina detaching it from its attachment.Īn exudative retinal detachment occurs due to inflammation, injury or vascular abnormalities that results in fluid accumulating underneath the retina without the presence of a hole, tear, or break.Ī tractional retinal detachment occurs when fibrous or fibrovascular tissue, caused by an injury, inflammation or neovascularization, pulls the sensory retina from the retinal pigment epithelium. ![]()
