Retinal detachment can occur more frequently after surgery for cataracts.Patients with a detachment related to myopia tend to be younger than non-myopic detachment patients. Myopia is associated with 67% of retinal detachment cases.

Retinal detachment is more common in those with severe myopia (above 5–6 diopters), as their eyes are longer, their retina is thinner, and they more frequently have lattice degeneration.

The lifetime risk in normal eyes is about 1 in 300. Detachment is more frequent in the middle-aged or elderly population with rates of around 20 in 100,000 per year. The risk of retinal detachment in otherwise normal eyes is around 5 in 100,000 per year. Prevalence of rhegmatogenous retinal detachment A retrospective Indian study of more than 500 cases of rhegmatogenous detachments found that 11% were due to trauma, and that gradual onset was the norm, with over 50% presenting more than one month after the inciting injury. Ī small number of retinal detachments result from trauma, including blunt blows to the orbit, penetrating trauma, and concussions to the head.

Tractional retinal detachment – A tractional retinal detachment occurs when fibrovascular tissue, caused by an injury, inflammation or neovascularization, pulls the sensory retina from the retinal pigment epithelium.

Exudative, serous, or secondary retinal detachment – An 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.

This is the most common form of retinal detachment, affecting approximately 1 in 10,000 individuals per year.

Rhegmatogenous retinal detachment – A rhegmatogenous retinal detachment occurs due to a hole or tear (both of which are referred to as retinal breaks) in the retina that allows fluid to pass from the vitreous space into the subretinal space between the sensory retina and the retinal pigment epithelium.

There are 4 main types of retinal detachment: Types Tear related retinal detachment - the retina has a horseshoe-shaped defect.

Ultrasound, MRI, and CT scan are commonly used to diagnose retinal detachment. Experiencing a 'dark curtain' or shadow moving across the field of vision.Symptoms of retinal detachment may include: The tear allows vitreous fluid to seep through it under the retina, and peel it away like a bubble in wallpaper.Īs the retina is responsible for vision, persons experiencing a retinal detachment have vision loss. Occasionally, posterior vitreous detachment, injury or trauma to the eye or head may cause a small tear in the retina. The retina translates that focused image into neural impulses and sends them to the brain via the optic nerve. The optical system of the eye focuses light on the retina much like light is focused on the film in a camera. The retina is a thin layer of light-sensitive tissue on the back wall of the eye. Initial detachment may be localized, but without rapid treatment the entire retina may detach, leading to vision loss and blindness. Retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue.
