| Summary: | The aim of this study was to evaluate the relationship between glucose levels and intraocular pressure (IOP) fluctuation in diabetic and nondiabetic patients. Seventeen nondiabetic and 20 diabetic subjects underwent a complete ophthalmic examination, capillary glucose testing, and applanation tonometry in two distinct situations: first, fasting for at least 8 hours and, second, postprandial measurements. Baseline glucose levels were higher in diabetic patients (P<0.001). Postprandial IOP was significantly higher than baseline IOP in diabetic (P<0.001) and nondiabetic patients (P=0.006). Postprandial glucose levels were significantly higher than baseline measurements in both diabetic (P=0.005) and nondiabetic patients (P=0.015). There was a significant association between glucose levels variation and IOP change in both diabetic patients (R2=0.540; P<0.001) and nondiabetic individuals (R2=0.291; P=0.025). There is also a significant association between the baseline glucose levels and IOP change in diabetic group (R2=0.445; P=0.001). In a multivariable model, the magnitude of glucose level change remained significantly associated with IOP variation even including age, baseline IOP, ancestry, and gender as a confounding factor (P<0.001). We concluded that there is a significant association between blood glucose levels and IOP variation, especially in diabetic patients. |
