Abstract
Purpose :
To report three cases of endophthalmitis after small gauge pars plana vitrectomy and their possible risk factor
Methods :
We retrospectively reviewed three groups of patients receiving different intra and post-operative procedure on cases that underwent 23-guage pars plana vitrectomy from January 2014 to May 2015 and analyze the possible risk factor for endophthalmitis after vitrectomy.
Results :
A total of 214 patients were included. Group A included patients who underwent same day intraocular pressure (IOP) measurement by tonopen; group B underwent same day IOP measurement by pneumotonometer; group C did not receive IOP measurement on the same day. Intra-operative betadine irrigation was performed in group A and B. There was no endophthalmitis happened in group A and C, however, three cases in group B. There was no significant difference between endophthalmitis group and non endophthalmitis group in sex, underlying disease, surgical indication, lens status, postoperative hypotony and surgical duration. Same day pneumotonometry is the only significant factor related to endophthalmitis after small gauge vitrectomy. Although not statistically different, two of the three cases were gas-filled eyes.
Conclusions :
Same day pneumotonometry might be a risk for endophthalmitis after small gauge pars plana vitrectomy. The procedure should be avoided on the day after operation, especially in gas-filled eyes.
