INTRODUCTION: This study investigated the contribution of vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1α (SDF-1α) angiogenic mediators in eyes with age-related macular degeneration (AMD).
METHODS: Aqueous humor specimens taken during cataract surgery in 7 cases of intermediate stage (nonexudative) AMD and 7 cases of late stage (exudative) AMD were evaluated using chemiluminescent immunoassay testing in this prospective case-control study. Mediator levels were compared with the normal reference values of 7 patients without any disease other than cataract.
RESULTS: The groups were similar in terms of age and gender (p>0.05). The aqueous humor levels of VEGF in both the intermediate AMD (median: 224.3 pg/mL, range: 44.8380.4 pg/mL) and late-stage AMD (median: 108.7 pg/mL, range: 61.9-223.5 pg/mL) patients were similar to those of the control group (median: 121.1 pg/mL, range: 24.9156.6 pg/mL) (p=0.256). Moreover, there was no significant difference in the SDF-1α concentrations between the intermediate AMD (median: 160.9 pg/mL, range 130166.3 pg/mL), late AMD (median: 161 pg/mL, range: 154.1.9171.6 pg/mL), and control group values (median: 161 pg/mL, range: 155.2219 pg/mL) (p=0.763).
DISCUSSION AND CONCLUSION: The aqueous humor levels of VEGF and SDF-1α were within the normal range in patients with intermediate and late-stage AMD.
