Abstract:
To observe the incidence of high intraocular pressure ( lOP ) and its risk factors in the early stage (within 7d) after 23 - gauge sutureless microincisional vitrectomy.
●METHODS: Retrospective case series study. Totally 98 patients ( 98 eyes ) who had undergone 23 - gauge sutureless microincisional vitrectomy were enrolled. lOP was measured by non-contact tonometry. High lOP was defined as an lOP > 25mmHg at any time within 7d after surgery. The influence of age, sex, side of operation, course of disease, primary disease pre - operation, reoperation, surgical options, type of tamponade, status of lens, surgical time on postoperative high lOP were analyzed.
● RESULTS: High lOP was found in 33 eyes ( 33. 7%) within 7d after surgery. High lOP was found in 8 eyes on postoperative 1d, the incidence was 24. 2% (8 / 33), and 25 eyes was found on postoperative 3d, the incidence was 75. 8% (25 / 33). The incidence of high lOP of male and female were 32. 8% ( 20 / 61 ) and 35. 1% ( 13 / 37 ) respectively. The incidence of high lOP of right and left eye were 36. 8% (21 / 57) and 29. 3% (12 / 41) respectively. There were no significant differences comparing age (Z =-0. 22), sex( χ2 = 0. 057), side of operation( χ2 = 0. 612), course of disease (Z= -0.079) and surgical time (Z= -0. 553) between patients with high lOP and those without it (P>0. 05). Similarly, no statistical significance was found between eyes with gas tamponade and silicone oil tamponade (χ2 = 1. 04), traumatic eyes and non traumatic eyes(χ2 = 0. 044), and retinal detachment eyes and without retinal detachment eyes ( χ2 = 2. 282, P > 0. 05 ). The incidence of high lOP in eyes with several operations was higher than that in eyes with the first operation ( χ2 =5. 211,P< 0. 05), in eyes with combined operations eyes was significantly higher than that in eyes with pure vitrectomy (χ2 = 4. 57,P< 0. 05), and in eyes with aphakic eye was higher than that in eyes with phakic eyes ( χ2 =4. 224,P<0. 05).
●CONCLUSlON:High lOP occurs commonly in 3d after 23- gauge sutureless microincisional vitrectomy. The risk factors of high lOP are reoperation, combined operations and aphakic eye.
