Retinal cryopexy (retinal cryotherapy) is used to treat retinal breaks; to destroy areas of ischemic retinal tissue; and to induce regression of retinal neovascularization (particularly if the surgeon feels that laser photocoagulation treatment cannot be administered); to directly destroy abnormal retinal blood vessels that are causing visual loss (for example, in Coats' disease); and to destroy small intraocular tumors (for example, selected retinoblastoma tumors.

INFORMATION

retina

The optic nerve carries signals generated by the photoreceptors (cones and rods).

Each photoreceptor is joined to the optic nerve by a tiny nerve branch.

The optic nerve is connected to nerve cells that carry signals to the vision center of the brain, where they are interpreted as visual images.
