Typically, this presents as a shower of many tiny dark drifting flecks or sometimes as cobwebs or drifting lines or squiggles in the eye. The sudden appearance of small floating specks within the eye, known as floaters.What are the Signs of a Retinal Detachment? Other eye conditions, such as a retinal hole or tear, diabetic retinopathy, or lattice degeneration.Certain eye operations, such as cataract surgery.Any degree of myopia (short-sightedness), with the risk of retinal detachment increasing as the degree of myopia increases.A history of a previous retinal detachment.While some retinal detachments occur for no identifiable reason, a situation known as an idiopathic retinal detachment, there are some known factors that can increase your risk. Nonetheless, treatment for a macula-off detachment is still recommended within 7-10 days for the best possible visual recovery. However, in a macula-off detachment, as the prognosis is immediately much poorer for recovering the central vision, immediate retinal surgery is less critical. As the central vision is still intact in a macula-on retinal detachment, ophthalmologists will recommend prompt treatment, typically within 24 hours, in order to preserve the vision. The status of the macula – whether it is detached or still attached – can determine how urgently retinal surgery needs to be performed. The macula is an anatomical part of the retina responsible for your central vision. A retinal detachment may occur just in one area of the retina, or in severe cases, the entire retina may come away, resulting in complete blindness in that eye.Įyecare professionals will often refer to a retinal detachment case as “macula on” or “macula off”. This results in a loss of sight in the area of the detached retina. Many eye care practitioners will describe a retinal detachment as like wallpaper peeling away from the wall. A retinal detachment occurs when the retina is separated from its underlying layers, removing its access to the support it needs to function. The retina must also, of course, be physically able to send along its neural signals via a connected network of cells. It’s the cells of the retina that receive the incoming light from the world around us, convert it to neural signals, and transmit these signals via the visual pathways to the necessary processing centres of the brain for vision.įor the retina to function properly (and for vision to work), it needs to be able to access the basic necessities – a blood and oxygen supply, plus a metabolic waste removal system. The retina is the layer of sensory tissue lining the back of the eye. Knowing the symptoms and signs of a retinal detachment can enable you to seek help quickly. Although a retinal detachment is painless, without attention from an ophthalmologist experienced in retinal surgery, the vision loss can be permanent and significant. A retinal detachment is considered an ocular emergency requiring prompt treatment to save your sight.
