3 Encircling Operation with Drainage for Primary Retinal Detachment
Fig. 3.4. Pathological specimen of an enucleated eye that had a tight encircling
buckle which had covered the vortex vein ampullas.The retina was
attached at the price of constriction and ischemia
inflammation and macular pigmentary changes that could also
be ascribed to the original detachment or aging. It is difficult to
propose to a patient that cutting the band at a small risk of redetachment
might prevent future macular changes and ill-defined
degeneration; however, the intervention might prove more effective
than daily antioxidants.
How Drainage Works
Although fluid drainage was part of Gonin’s ignipuncture technique,
it had been performed without attention to retinal breaks
and accordingly with predictably poor results. Rosengren, who
injected air intravitreally, also drained [23]. Arruga and Schepens
both drained subretinal fluid to bring the neuroepithelia into
apposition and to make space for the volume reduction that
