Lamina cribrosa defect and progress of glaucoma
Liu XY; Fan NChinese Journal of Ophthalmology 2020; 56: 17-20
Lamina cribrosa (LC) is considered as the original site of glaucomatous damage of axons of retinal ganglion cells, and therefore understanding the morphological changes in the LC will help to uncover the pathogenesis of glaucoma. Previous studies have indicated that the progress of glaucomatous optic neuropathy may be associated with the LC defects. Based on imaging by swept source optical coherence tomography B-Scan of the optic discs of patients with glaucoma, for the first time the spontaneous local LC defects have been found to balance the gradient between intraocular and cerebrospinal fluid pressures, which in turn can slow down the progress of glaucomatous optic neuropathy. This article provides the direct evidence supporting the role of intraocular and cerebrospinal fluid pressure gradient in the pathogenesis of glaucoma. This finding will increase our understanding of the mechanisms underlying glaucoma and help to develop novel strategies for its treatment and prognosis analysis. -.
