Abstract

was hypotensive anesthesia used? We have noted that, during endoresection of choroidal melanoma, intraocular hemorrhage may be very severe and may not be controlled with hypotensive anesthesia and raised infusion pressure alone. Perfluorocarbon liquids may be needed as a temporary tamponade which is replaced with silicone oil on around day 10. 4 It would be interesting to know specific difficulties, if any, the authors faced during endoresection of retinoblastoma, considering that calcifications within the mass may be difficult to cut/remove with the cutter. In how many cases did the authors remove silicone oil and what was the usual time interval between the primary vitrectomy and the silicone oil removal?
