Sažetak
The aim of this study was to evaluate macular thickness parameters in glaucoma patients and to compare them to
normal subjects using Optical Coherence Tomography (OCT). This prospective, observational study included 20 primary
open angle glaucoma patients (POAG) and 20 healthy subjects in control group. Exclusion criteria were diabetes and
other macular pathology, like age-related macular degeneration, macular oedema, central serous retinopathy and high
myopia >4.00 dsph. OCT imaging of peripapillar retina and macular area were performed using Cirrus HD OCT. In
these two groups of patients we analyzed changes of macular thickness parameters (central subfield thickness, macular
volume, and average macular thickness). The group of glaucoma patients had decreased values of the two macular thickness
parameters: macular volume and average macular thickness, compared to control group. There was no difference in
central macular thickness, presumably because of the absence of the ganglion cells in this layer. Macular imaging can be
a useful additional method to determine glaucoma status and has a potential for tracking glaucoma progression.
