Thinning of the Lamina Cribrosa and Deep Layer Microvascular Drop Out in Patients with open angle glaucoma and High Myopia.

Highly myopic eyes with open-angle glaucoma appear to have a thinner lamina cribrosa, which was associated with elevated intraocular pressure and deep-layer microvasculature dropout. lamina cribrosa thinning (≤128.00 µm) helps distinguish open-angle glaucoma from high myopia with an abnormal retinal nerve fiber layer thickness distribution and unclear shallow disc cupping.
