The mean prevalence of high myopia increases over time in Egypt Prevalence of high myopia in Egypt which was 0.2%, in 1960 increased to 7.4% in 1976 and 10.8% in 2015. Optical coherence tomography (OCT) is a noninvasive, painless and quick precise technology that can be used for interpreting tissue structure and function. Time-domain OCT was fast enough to scan a circle centered on the optic nerve head (circumpapillary) to assess the retinal nerve fiber layer (RNFL) thickness. Glaucoma Module Premium Edition (GMPE) is a new, objective method of ONH analysis using BMO. The termination of Bruch's membrane at the ONH marks the opening through which RGC axons exit the eye to form the choroidal and scleral portions of the neural canal, this anatomic opening, termed Bruch's membrane opening (BMO). The minimum distance from the BMO to the internal limiting membrane represents the most geometrically accurate measurement of neuroretinal rim width. This neuroretinal rim measurement has been termed Bruch's Membrane Opening-Minimum Rim Width (BMO-MRW).
