Lamina cribrosa in primary open angle glaucoma

Lamina cribrosa in primary open angle glaucoma

Category(ies): Glaucoma, Iris
Contributor: Jesse Vislisel, MD

This patient has a deep optic nerve head cup and prominent inferotemporal notch secondary to optic nerve damage from primary open angle glaucoma. The deep cup reveals the lamina cribrosa, a fenestrated region composed of connective tissue and elastic fibers. This mesh-like structure allows the ganglion cells forming the optic nerve to pass through the scleral wall.
