Variability of blood pressure and blood glucose during perioperative period for patients with secondary neovascular glaucoma after silicone oil removed in PDR

Abstract

AIM:To research blood pressure and blood glucose variability during peroperative period for patients with secondary neovasular glaucoma(NVG)after silicone oil removed in proliferative diabetic retinaopathy(PDR).METHODS: Totally, 271 patients(271 eyes)undergone surgery of vitrectomy and silicon-oil tamponade combined with cataract were respective analyzed. Fourteen patients(14 eyes)with secondary NVG after silicon oil removed and randomly controlled group of no NVG according with ages, operation method in the same time were studied. The blood pressure and blood glucose variability during peroperative period was analyzed, and did comparison after excluded contralateral eye. The complications of 271 patients were surveyed in following-up period 1～12mo. The incidence of NVG, the time, blood pressure, blood glucose and glycated hemoglobin(Hbc%)variability during peroperative period was statisticed and compared by software of SPSS 11.0.RESULTS: Fourteen eyes(5.2%)of 271 cases was with secondary NVG(female: 4 eyes, 28.6%; male: 10 eyes, 71.4%), average ages was 57.07 years(49～68 years). NVG presented in the 107～ 135d after vitrectomy and 7～45d(average 31.78d)after silicon-oil removed. Diabetes mellitus was 10～15(average 13.2)a. In NVG group, the variability of blood glucose was 4.0～10.2mmol/L(mean 8.52±3.24mmol/L), variable coefficient was 0.48. In NNVG group, the variability of blood glucose was 5.0～8.2mmol/L(mean 7.22±0.24mmol/L), variable coefficient was 0.43. It was significantly difference in comparison in variable coefficient(PPPPCONCLUSION: There are significant variability on fasting blood glucose, daytime SBP and night DBP during perioperative in PDR patients with secondary NVG. It might be occurred 1wk after silicone oil removal surgery.
