Laser photocoagulation and cryopexy are used to fix tears
retina and prevent a
retinal detachment. These methods can be used if fluid
has not begun to collect between the two layers of the retina. These
methods work well to treat certain retinal tears. But some people will need
future treatment for a tear in another part of the retina.
You can usually receive these treatments in a doctor's office or an
outpatient surgery center. They do not require a
hospital stay or
general anesthesia. You may need to limit your activity for a couple of weeks after treatment.
In laser photocoagulation, an intense beam of light travels
through the eye and makes tiny burns around the tear in the retina. Over
several weeks the burns form scars that prevent fluid from getting under the
achieves the same result by using a probe to freeze and seal the retina around
By attaching the retina to the layers beneath it, both
methods keep fluid in the middle of the eye from passing through the retinal
tear. During retinal detachment surgery, the same methods are used to hold the
reattached retina in place and to keep fluid from collecting under it.
