Tomography features of the lamina cribrosa and its scleral canal in different types and stages of the diabetic optic neuropathy

Methods. 575 patients (1150 eyes) with type 2 diabetes mellitus (DM) and 50 non-diabetic control persons (100 eyes) aged 55,9±7,8 years were examined. LC thickness was measured with optical coherent tomography (OCT) using LC_Thickness_programm.m and main_low_noise_filters_programm.m. The area of LC scleral canal was measured with SD OCT using the LC_cut_position_programm.m and LC_diameter_calculation_programm.m.
