When your retina (a light-sensitive layer of tissue at the back of your eye) is pulled away from its normal position, you have a retinal detachment.
Retinal detachment is a medical emergency, and prompt treatment is critical to preserving your vision. Retina Surgery is used to treat this.
If you have a retinal detachment, you may need surgery within a few days to reattach your retina to the back of your eye. You may need to stay in the hospital for a short period of time following surgery, and it may take several weeks before your vision improves.

Doctors can perform three types of surgery to repair a detached retina:
• Retinopexy pneumatica
• Scleral buckling
• Vitrectomy
The type of surgery you require will be determined by several factors, including how much of your retina is detached and where it is detached in your eye. Your doctor will advise you on which type is best for you, as well as the risks and benefits of surgery. Some people may require more than one type of surgery at the same time.
Your doctor may also use laser or freeze treatments during the surgery to repair tears or holes in your retina and to help keep your retina in place after surgery.
Treatment
A retinal tear, hole, or detachment is almost always repaired surgically. There are numerous techniques available. Inquire with your ophthalmologist about the risks and benefits of each of your treatment options. You and your doctor can decide which procedure or combination of procedures is best for you.
Tears in the retina
If a retinal tear or hole has not yet progressed to detachment, your eye surgeon may recommend one of the following procedures to prevent detachment and preserve vision.
• Laser treatment (photocoagulation). A laser beam is directed into the eye by the surgeon through the pupil. The laser creates scarring around the retinal tear, which "welds" the retina to the underlying tissue.
• Subzero temperatures (cryopexy). After numbing your eye with a local anaesthetic, the surgeon applies a freezing probe to the outer surface of the eye directly over the tear. The freezing creates a scar, which aids in the attachment of the retina to the eye wall.
Both of these procedures are performed as outpatient procedures. Following your procedure, you will most likely be advised to avoid activities that may jar the eyes, such as running, for a couple of weeks.
