Lamina cribrosa sclerae - Wikipedia
The nerve fibers forming the optic nerve exit the eye posteriorly through a hole in the sclera that is occupied by a mesh-like structure called the lamina cribrosa. It is formed by a multilayered network of collagen fibers that extend from the scleral canal wall.
Lamina cribrosa - American Academy of Ophthalmology
A healthy optic nerve has approximately 1.2 million nerve fibers. These nerve fibers pass through a sieve-like portion of the posterior sclera, called the lamina cribrosa, before exiting the eye. It is here that glaucomatous damage is thought to occur.
Lamina Cribrosa in Glaucoma - PMC - National Center for …
The lamina cribrosa (LC) is a fenestrated, three-dimensional network of load-bearing trabeculae, many of which contain capillaries, that provides structural and nutrient support to the RGC axons as they leave the eye on their path to the brain.
Lamina Cribrosa in Glaucoma: Diagnosis and Monitoring
2015年6月1日 · The lamina cribrosa is the putative site of retinal ganglion cell axonal injury in glaucoma. Although histological studies have provided evidence of structural changes to the lamina cribrosa, even in early stages of glaucoma, until recently, the ability to evaluate the lamina cribrosa in vivo has been limited.
Optical Coherence Tomography Imaging of the Lamina Cribrosa: …
2021年2月19日 · The lamina cribrosa (LC) is a mesh-like structure localized in the posterior scleral canal of the optic nerve head (ONH), allowing retinal ganglion cell (RGC) axons to pass through to the brain. It is a fenestrated complex that also …
Imaging of the lamina cribrosa and its role in glaucoma: a review
2017年12月7日 · The lamina cribrosa (LC) is a reticulated, sieve-like structure that fills the posterior scleral foramen, which unmyelinated retinal ganglion cell (RGC) axons pass through before converging as the optic nerve (ON).
Lamina Cribrosa - SpringerLink
2015年4月4日 · The lamina cribrosa, a multi-layered sieve-like structure in the optic nerve head, has been proposed as a primary site of axonal damage in glaucoma. The lamina cribrosa provides structural and functional support to the retinal ganglion cells axons as they pass from...
Imaging of the lamina cribrosa and its role in glaucoma: a review
The lamina cribrosa of the optic nerve head serves two contrasting roles; it must be porous to allow retinal ganglion cell axons to pass through, and yet at the same time, it must also provide adequate structural support to withstand the stresses and strains across it.
Lamina Cribrosa Morphology Predicts Progressive Retinal …
2018年1月15日 · A growing body of evidences suggests that posterior bowing of the lamina cribrosa (LC) is the earliest structural change preceding the retinal nerve fiber layer (RNFL) loss in glaucomatous...
