Retinectomy

In eyes with a large area of denuded RPE, hypotony ensues; this has even been utilized in bringing down the IOP in blind eyes with otherwise intractable glaucoma (see Chap. 2.18).

The treatment is destruction of the RPE in the area of retinectomy to prevent aqueous drainage, or silicone oil implantation to prevent aqueous access. A blunt-tipped diathermy probe is used for choroid (RPE) destruction; it is much more difficult and risky to use scissors or the vitrectomy probe for this purpose.
