Abstract
Purpose:
Recent studies have shown that normal tension glaucoma (NTG) patients have more systemic disease compared with normal subjects. The purpose of this present study was to analyze the hematological and biochemical data of NTG patients and normal control subjects, and then compare the differences between those two sets of data.
Methods:
This study involved 519 NTG patients (NTG group; 259 females and 260 males, mean age: 61.7±10.9 years) and 438 age-matched normal controls (NC group; 220 females and 218 males, mean age: 62.4±7.2 years) who consulted at the Glaucoma Clinic of Kyoto Prefectural University of Medicine, Kyoto, Japan. Hematological and biochemical data (23 parameters) were analyzed and compared between the two groups using the Welch's t test. Bonferroni’s correction was performed, and a p-value of <0.002 was considered statistically significant. In addition, a comparison between the females and males of both groups, respectively, was performed.
Results:
Of the 23 parameters, a significant difference was found in the following 6 parameters: Lactate Dehydrogenase (LDH), total protein (T-Pro), albumin (Alb), glucose, triglyceride, mean corpuscular hemoglobin concentration (MCHC), and platelet counts (Plt). LDH, T-Pro and Plt were found to be significantly higher in the NTG group than in the NC group. There were significant differences in LDH and MCHC with females and LDH and triglyceride with males, respectively.
Conclusions:
The findings of this study show that NTG patients have significant differences in the multiple parameters of blood serum data compared with age-matched normal control subjects.
