Abstract
PURPOSE: To report a complication of retained silicone tip from a diamond-dusted membrane scraper (DDMS) that occurred while using a valved cannula vitrectomy system. METHOD: Retrospective review of three cases that underwent 23 gauge (G) sutureless vitrectomy for idiopathic macular hole (cases 1 and 2) and myopic macular schisis (case 3). RESULTS: In all three cases following a standard vitrectomy, the internal limiting membrane (ILM) peeling was initiated by using a 23G DDMS. During the insertion of the DDMS, the flexible silicone tip of the 23G DDMS was detached from the metal shaft and was retained in the 23G valve system and in case 3, the silicone tip got dislodged from the valve onto the retina. Subsequent ILM peeling was completed by using an end-gripping forceps. All underwent intravitreal gas injection at the end. No other complications were noted. CONCLUSION: These three cases demonstrate an uncommon complication of retained silicone tip within the valved cannula vitrectomy system and this complication should be considered while using flexible instruments in valved cannula systems.
