Evaluation of Blood Components of Glycemic Control in Diabetics with and without Cataract in Comparison with Nondiabetics.

Cataract is a leading cause of vision loss in the world. Several factors are involved in the development of cataracts, of them; diabetes and uncontrolled plasma glucose have great importance. Therefore, controlling glycemic reduces the risk of related to microvascular complications of diabetes diseases such as cataract. This study aimed to compare fasting plasma glucose (FPG), HgbA1c, and oral glucose tolerance test (OGTT) between Diabetic patients with and without cataract in comparison with the healthy group as control. Among 150 subjects, 50 diabetic patients, 50 diabetic cataracts, and 50 healthy individuals without a history of specific disease were compared with each other. Fasting plasma glucose, OGTT, and HgbA1c were measured by colorimetric methods. SPSS23 software was used to analyze data. P-values less than 5% or lower were considered to be statistically significant. In this study, the mean fasting plasma glucose, HgbA1c, and OGTT in the group of diabetic patients, diabetic with cataract, and healthy groups fasting plasma glucose were as follow, 162.46 mg dL -1 and 184.76 mg dL -1, 92.88 mg dL -1 (P˂0.05), HgbA1c: 7.8, 8.0, 5.8% (P˂0.05) and OGTT: 228 mg dL -1, 246.12 mg dL -1 and 114.32 mg dL -1 (P˂0.05) respectively. Our findings showed that in diabetic patients with and without cataract, fasting plasma levels, HgbA1C, and OGTT are higher than the healthy group. There was a significant relationship between the studied factors and cataracts. As a result, high blood glucose has a definitive role in the development of cataracts. [ABSTRACT FROM AUTHOR]
