What factors guide your decision to perform subretinal fluid drainage during primary scleral buckle surgery for a rhegmatogenous retinal detachment?
Since external drainage of subretinal fluid is the step in scleral buckle surgery associated with the greatest risk of serious complications (i.e. subretinal hemorrhage, retinal perforation, retinal incarceration), I only drain if the subretinal fluid so bullous that drainage is necessary to insure ...
Over the years, I have been both a maximalist and a minimalist in this subject. Over the last 10 years, at least I've trended towards drainage in most cases. The risk of complications is very small compared to the risk of failure without it, or prolonged recovery with possible chronic SRF and ensuin...

Also, if the pressure goes up to the point that the nerve isn’t perfused, I would rather drain than do an AC tap because I want the subretinal fluid to go away anyway. Chronic fluid can take u...
