Retinectomy as a Pressure Lowering Procedure

The rational for a retinectomy in the context of refractive glaucoma is the fact that the retina is the main barrier for the transition of water from the vitreous cavity to the choroid. The advantage of a retinectomy in refractive glaucoma is, that a retinal hole cannot close/heal. Thus the IOP lowering effect lasts as long as the underlying choroidal sponge is perfused. Complications are PVR retinal detachment. That is why it is advisable to reserve retinectomy to eyes only when in a stage of
