Comparison of Serum Biochemical and Haematological Analyses in Patients with Age-Related Macular Degeneration and Diabetic Retinopathy

Abstract

We evaluated biochemical analysis results with the aim of discovering serum levels that have possible effects and differences on age-related macular degeneration (AMD) and diabetic retinopathy (DRP). A retrospective case-control study was conducted between January 2017 and January 2018 on a total of 114 patients (84 DRP, 30 AMD) and 24 age and sex-matched control individuals. Four groups were created; 52 patients with proliferative DRP (PDR), 32 patients with nonproliferative PDR (non-PDR), 30 patients with wet AMD and 24 control individuals. Serum biochemical (HbA1C, fasting glucose, AST, ALT, C-reactive protein, albumin, total protein, uric acid, triglyceride, HDL, LDL, total cholesterol, Na, K, urine albumin) and complete blood count (CBC) analyses were performed at the time of diagnosis. Descriptive statistics, one-way ANOVA and Kruskal-Wallis tests were performed using SPSS to analyse data (Version 22.0). The mean age of patients was 63.3 years ± 6.4 (49-91year), and that of control individuals was 65.3 years ± 9.3 (50-88 year). Post hoc analysis showed statistically significant differences in HbA1c and fasting glucose levels among PDR-AMD, PDR-control, non-PDR-AMD, and non-PDR-control groups (whole, P
