Summary
The assessment of macular VD by swept-source OCTA may offer additional information for detection of glaucoma.
Abstract
PURPOSE
To evaluate the macular capillary network density of superficial and deep retinal layers (SRL/DRL) by swept-source optical coherence tomography angiography (OCTA) in patients with primary open angle glaucoma (POAG) and to compare the results with those of normal subjects.
METHOD
In this prospective study, 24 eyes of 24 normal individuals and 24 eyes of 24 patients with mild to moderate POAG underwent fovea centred 6×6 mm cube macular OCTA imaging by a swept-source OCTA device (Triton, Topcon, Tokyo, Japan). Quantitative analysis of the retinal vasculature was performed by assessing vessel density (VD) as the ratio of the retinal area occupied by vessels at the SRL and DRL.
RESULTS
The mean VD (ratio) at the SRL and DRL was statistically significantly lower in patients with POAG (SRL, p0.05).
CONCLUSION
The assessment of macular VD by swept-source OCTA may offer additional information for detection of glaucoma.
