Therefore, having it become detached can create permanently altered vision, or the loss of vision entirely. Now that we know what a retina is, what exactly does it mean for it to detach, and how does it happen?
The retina is secured to the backs of our eyes by a clear gel called the vitreous. This gel is what is inside of our eyeballs and keeps them maintaining their round shape. As humans age, the vitreous in the eyeball can start to shrink or become smaller. This makes the eyeball change shape, and it can tug on the retina itself.
Some changes to the vitreous and retinal tugging are actually fairly normal. Most people experience this as seeing a little flash of light. However, a retinal detachment happens when the vitreous tugs so hard on the retina that the retina moves away from the eyeball.
If too much fluid gets in between the eyeball and retina, this can cause retinal detachment. Once detached, the retina can no longer do its job of sending light signals to the brain, which can cause a loss or alteration of vision. The most common risk factor for retinal detachment is age. Most people who experience detachment are over the age of A retinal detachment, however, can occur at age. If you sustain blunt force trauma to the eye, this can also cause retinal detachment.
This can happen by blood cells getting in between the retina and vitreous it is attached to, which can ultimately make someone lose their vision, or their eye entirely. People who have diabetes are also known to be more prone to developing a retinal detachment. If you have diabetes , you should speak to your doctor about what you can do to possibly prevent retinal detachment and your risk factors.
Individuals with severe nearsightedness are also more prone to developing a detachment. This is because their eyes change shape, which makes it more difficult for them to see clearly. Often times, this is genetic. Finally, individuals who have a close family member who has experienced a retinal detachment are also more likely to experience one themselves. Most people will also have had symptoms for a couple of days or weeks leading up to the detachment that serve as a warning that there might be a problem.
The cost of surgery for retinal detachment depends on the type of procedure. The study , published in the journal Ophthalomology , balanced the cost of treatment against the benefits of good eyesight and quality of life. There is a small risk of complications after surgery.
These include allergies to medications, bleeding in the eye, double vision , cataracts, glaucoma , and eye infection. Attending regular eyesight tests can help to reduce the risk of retinal detachment, as eye conditions such as this can sometimes be detected in the early stages. If a doctor suspects retinal detachment, they will normally refer the patient to an eye specialist, or ophthalmologist, for a precise diagnosis.
The ophthalmologist will examine they eye after dilating, or widening, the pupils with eye drops. An ultrasound may give more detail. The eyes are incredibly complex organs. In this article, we explain their anatomy, how they work, and describe some conditions that affect the eyes. Glaucoma is an eye condition that can lead to vision loss. It is common among older adults and those with some health conditions. Here, find out how…. A stroke is caused by an artery blockage in the brain, and an eye stroke can occur due to blockage in the retina.
Epiretinal membranes ERMs are thin tissues that can form a layer on the inside of the retina. Symptoms include a loss or distortion of vision and…. Eye pain can occur for a number of reasons, depending on which part of the eye is affected.
The type of surgery you need will depend on several things, including how much of your retina is detached and where in your eye it detached. Your doctor will talk to you about what type they recommend, and about the risks and benefits of surgery.
Some people may need more than one type of surgery at once. During the surgery, your doctor may also use laser or freeze treatments to repair tears or holes in your retina and help hold your retina in place after surgery. In pneumatic retinopexy, your doctor will inject a small air bubble into your eye. The bubble will push your retina back into place so your doctor can use a laser or freeze treatment to repair any holes or tears.
The bubble will disappear on its own over time. What is retinal detachment? What are the symptoms of retinal detachment?
