Study aiming to evaluate Macular Vascular Density in High Myopes without pathological myopic maculopathy in outpatient clinic in Sohag teaching hospital using OCTA .

Study Design : This is a cross sectional observational study , of about 50 patients attending ophthalmology outpatient clinic at Sohag Teaching Hospital .

Inclusion criteria :

Exclusion criteria :

The exclusion criteria will include :

• History of other any ocular diseases , systemic diseases that may affect the ocular circulation .
• Previous intraocular surgery or ocular injury .
• Any patient with pathological myopic maculopathy (epiretinal membrane, foveoschisis, macular holes, lamellar holes, Lacquers cracks, choroidal neovascularization and retinal atrophy ) .

Inclusion Criteria wil include :

• All myopic patients with axial high myopia (-6 spherical refractive error or more) of different age groups .

Exclusion Criteria will include :
