Scleral Buckling Cryoretinopexy

A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break.

Scleral buckles come in many shapes and sizes. An encircling band is a thin silicone band sewn around the circumference of thesclera of the eye. Buckles are often placed under a band to create a dimple on the eye wall.

The scleral buckle is secured around the eyeball under the conjunctiva. This moves the wall of the eye closer to the detached retina. It also may move the retina closer to thevitreous. This alteration in the relationships of the tissues seems to allow the fluid which has formed under the retina to be pumped out, and the retina to re-attach. The physics orphysiology of this process are not fully understood.

Retinal detachment surgery usually also involves the use of cryotherapy or laser photocoagulation. The laser or cryotherapy forms a permanent adhesion around the retinal break and prevents further accumulation of fluid and re-detachment.

Scleral buckles are done using local or general anesthesia and are often done as outpatient procedures. In the majority of treatments the buckle is left in place permanently, although in some instances the buckles can be removed after the retina heals. The buckle may also be removed in the event of infection.

A link between scleral buckles and Adie syndrome may exist.

the use of extreme cold to freeze areas of weak or torn retina in order to cause scarring and seal breaks. It is used in cryosurgery for retinal detachment and also in certain other ischaemic conditions of the retina (e.g. diabetic retinopathy).
