What are the warning symptoms of a retinal detachment? weak areas in your retina that can be seen by your retinal doctor.previous retinal detachment in your other eye.The following conditions increase the chance of having a retinal detachment: However, if the vitreous pulls hard enough to tear the retina, fluid may pass through the retinal tear, lifting the retina from the back wall of the eye, much like wallpaper can peel off a wall. The vitreous may pull away from its attachment to the retina. A retinal detachment is a very serious problem that can cause blindness unless it is treated.Ī clear gel called vitreous fills the middle of the eye. Vision is blurred, just as a photograph would be if the film were damaged or loose inside the camera. When the retina is detached, the retina does not work. Think of the retina as the film that lines the back of the camera.Ī retinal detachment occurs when the retina is pulled away from its normal position. The lens in the front of the eye focuses light onto the retina. It senses light and sends images to your brain. (The use of silicone oil is usually reserved for complex retinal detachments such as those with associated scar tissue or very large retinal tears.The retina is a nerve layer that is located at the back of the eye. Silicone oil may be removed at a later date with another vitrectomy. Gas goes away slowly on its own, but oil does not. Lastly, the eye is filled with either gas or silicone oil. Laser is then used to seal the retinal tears. As the name implies, it involves surgical removal of the vitreous gel which, in turn, relieves the traction or pulling on the retinal tear that is causing the detachment. Vitrectomy surgery is also performed in the operating room. In some cases, a scleral buckle may be combined with vitrectomy surgery. A gas bubble is sometimes used to facilitate reattachment of the retina. It is coupled with either cryotherapy or laser photocoagulation. It consists of suturing a soft piece of silicone to the eye wall (sclera) in such a way as to gently indent the sclera in order to support and close the retinal tear.
Scleral buckle surgery is performed in the operating room. After the procedure, patients must maintain a specific head position for about a week to ensure that the retinal tear is adequately sealed The gas injection is coupled with either a freezing treatment (cryotherapy) or laser photocoagulation to permanently seal the causative retinal tear. It involves the injection of a temporary gas bubble to close the retinal tear and surrounding detachment. Pneumatic Retinopexy is an office-based procedure. The choice of treatment depends on certain features of the detachment such as number and location of retinal tears as well as patient characteristics such as age and past cataract surgery. There are three approaches to repairing a retinal detachment:
However, if a retinal detachment has already developed, a retinal reattachment procedure is typically necessary. If a retinal hole or tear is detected before there is retinal detachment, laser or cryotherapy (freezing treatment) to the retinal tear is often successful in sealing the retinal defect, preventing a retinal detachment.

Treatment and How to Prevent Retinal Detachment Longstanding retinal detachments or those with associated scar tissue (proliferative vitreoretinopathy) typically have a poor visual prognosis. A change of eyeglasses after retinal detachment surgery may or may not improve vision. Final visual outcomes are best if the detachment is detected and treated before it involves the center of the retina (macula). Retinal detachments often cause some degree of permanent visual field or central visual acuity loss, even after successful reattachment. There may also be some degree of vitreous hemorrhage, which occurs when a retinal tear involves a retinal blood vessel. Through a dilated pupil, the ophthalmologist will see one or more tears in the retina with varying amounts of underlying fluid. A comprehensive ophthalmic examination is essential to diagnose and treat a retinal detachment.
