Optic nerve at the level of the lamina cribrosa
in an eye filled with silicone oil shows numerous clear spaces.
Focal lamina cribrosa
defects associated with glaucomatous rim thinning and acquired pits.
With its high-resolution capability, this new technology enables a closer evaluation of the internal structure of drusen and their relationship with the lamina cribrosa
Central retinal vein occlusion (CRVO) is usually due to a fibrin and platelet thrombin before or at the level of lamina cribrosa
Optic disc hemorrhage can be caused not only by ischemic microinfarction in the optic disc, but also by mechanical rupture of small blood vessels arising from structural changes at the level of the lamina cribrosa
Myelination of the anterior visual system begins centrally at the lateral geniculate body at 5th month of embryonic development and proceeds distally to chiasm by 6-7 months, the retrobulbar optic nerve by 8 months, and the lamina cribrosa
Cerebrospinal fluid (CSF) cytology and bone marrow biopsy were advised for all patients with infiltration of iris, ciliary body, choroid, optic nerve lamina cribrosa
, retrolaminar optic nerve, optic nerve to the line of transection, sclera, and extrascleral structures.

Optik sinir avulsiyonu cesitli travmalar sonucu olusan ve optik sinirin lamina cribrosa

It can be hypothesied that the deformation and thinning of the lamina cribrosa
in highly myopic eyes is similar to that which occurs in the lamina cribrosa
