Abstract
The retina may have to be excised because it is shortened or has adherent to it contractile tissues that need to be removed but which cannot be separated from the retina. Retinectomy, however, is not a procedure without its own serious risks. The VR surgeon must fully be aware of when and how the procedure should be done as well as what needs to be avoided. Retinotomy is a more straightforward surgical step, whether it is a localized one for drainage or acts as a precursor to retinectomy. Chorioretinectomy is technically easy but the list of conditions for which it is effective remains to be determined.

“Peripheral” here means a retina that is peripheral to the retinotomy (see below), not necessarily a retina anterior to the equator.
- 2.
The cornea in the aphakic eye.

Especially if smaller than 20 g.

This is why the correct name of the procedure is retinectomy.
- 5.
Anatomically, the retina can adapt amazingly well to being twisted around the optic disc: I once saw a patient who underwent seven surgeries for PVR and had a retina that was reattached after 360° retinectomy, but it was turned 180°. Functionally, as little as 10° misalignment can cause severe visual disturbance.
- 6.
Fibroblasts and the RPE.

See above (Sect. 33.1) the caveats about diathermy use.
