Factors predicting duration of intraocular gas presence after 23-gauge transconjunctival sutureless vitrectomy for rhegmatogenous retinal detachment.
OBJECTIVE
To investigate factors predicting duration of intraocular gas presence in 23-gauge transconjunctival sutureless vitrectomy.


METHODS
Retrospective review of 130 eyes that underwent 23-gauge transconjunctival sutureless vitrectomy. At the end of surgery, gas exchange and sclerotomy massage to promote self-sealing were performed. If sclerotomy leakage was suspected despite sclerotomy massage, a suture was placed. Factors predicting duration of intraocular gas presence in 23-gauge transconjunctival sutureless vitrectomy were examined using multiple regression analysis. An F value greater than 2 and P value less than 0.05 were considered statistically significant.


RESULTS
Significant factors were axial length (F = 7.08; P < .05) and IOP on postoperative day 1 (F = 4.35; P < .05). Age, operation time, preoperative IOP, and number of sutured sclerotomies were not statistically significant.


CONCLUSIONS
Factors predicting duration of intraocular gas presence in 23-gauge transconjunctival sutureless vitrectomy were axial length and postoperative IOP on day 1.
