How is choroidal detachment different from retinal detachment?
An echographic (ultrasound) image of the eye shows a choroidal detachment. Your retina specialist can use these images to differentiate a choroidal detachment from a retinal detachment, characterize the size and type of the choroidal detachment (ie serous, hemorrhagic, or mixed), and monitor changes over time.
What happens if the retina detaches from the choroid?
If the retina is detached from the choroid, the photoreceptors will fail. The fovea has no retinal blood vessels and depends wholly on the choroid for its oxygen, so detachment of the macula leads to permanent damage to the cones and rods at the posterior pole, and loss of vision.
What happens if the choroid is damaged?
Patients with uncomplicated choroidal ruptures have a good chance of full recovery. May cause choroidal neovascularisation, which can lead to haemorrhagic or serous macular detachment. This most often occurs during the first year after the injury but has been reported up to five years after injury.
What causes choroidal effusion?
The primary cause of choroidal effusion and hemorrhage is low IOP, although inflammation can sometimes play a role. Other risk factors include anticoagulation, aphakia, high myopia, prior ocular surgery, hypotony, straining, hypertension, and heart and respiratory disease.
What you should know about choroidal detachments?
Choroidal Detachment Symptoms. When the choroid is detached from the back wall of the eye, patients may not feel anything at all, or may feel that the eye is achy and sore. Causes. In general, choroidal detachments can be categorized as “serous” (fluid filled), or “hemorrhagic” (blood filled). Diagnostic testing. Treatment and prognosis.
What causes detached retinas?
A detached retina occurs when the retina moves away from its normal position. This can be the result of a tear, break, or hole. When the vitreous gel pulls loose—this is a clear gel inside of the eye and in front of the retina—it can exert traction on the retina. If the retina is already weak, it will tear and ultimately detach.
What causes a torn retina?
The retinal tear that triggers a retinal detachment sometimes is caused by trauma. More often, it is caused by a change in the gel-like consistency of the vitreous fluid that can occur as a part of aging.
What is a torn retina?
A retinal tear is a rip that occurs when the eyeball’s vitreous liquid or “jelly” slides and pulls on the retina.
