Infiltration posterior to
lamina cribrosa, but not involving the cut end of Optic Nerve (Both also had less than 8 mm Optic Nerve length)--Two patients
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 at term.
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.

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 in OAG.
