This is a part of the sclera which is situated at the site of attachment of the optic nerve, 3 mm to the inner side of and just above the posterior pole of the eye. There, the sclera is a thin sieve-like membrane through which pass fibres of the optic nerve. Syn. lamina cribrosa (although this term also refers to the striated portion of the bulbar optic nerve which includes the cribriform plate). See myelinated nerve fibres.
