Brief Summary
the goal of this obsrevational study is to learn about retinal nerve fibres and if their numbers changed with axial length of the globe or not. the main question to answer is there is effect of long axial length on the thickness of the retinal nerve fibers participants will be asked to:
- measure the axial length with ultrasound
- measure the thickness of retinal nerve fibers with optical coherence tomography
