In complicated retinal detachment cases where the retina fails to reattach after completing the usual steps, retinectomy is a better technique than relaxing retinotomy–and the retinectomy is best done incrementally under air.
“Retinectomy has advantages compared with relaxing retinotomy because retinectomy removes all the necrotic tissue anterior to the circumferential cut and reduces the risks of anterior segment neovascularization, chronic hypotony, and probably proliferative vitreoretinopathy (PVR) recurrence,” said Steve Charles, MD.
Dr. Charles is founder of the Charles Retina Institute and clinical professor of ophthalmology, University of Tennessee, Memphis. He also developed the retinectomy-under-air technique.
“An advantage of retinectomy-under-air rather than under-balanced, salt solution, or perfluoro-n-octane (PFO) is that the surgeon is better able to judge the right amount of tissue to remove,” Dr. Charles explained. “Retinectomy-under-air reduces the need for hemostasis, and by avoiding PFO, it saves money and eliminates subfoveal PFO.”
