“…From the pars plana to the optic nerve, the basal lamina of the Müller cells has a true lamina densa that receives the insertion of vitreous collagen fibrils. The composition of the lamina includes collagen IV, and also type I collagen, laminin, fibronectin and proteoglycans 2 . At the border of the optic disc the retinal internal‐limiting lamina (ILL) continues as the basal membrane of Elschnig's astrocytes.…”

Elschnig's basal membrane is described by Heergaard et al as composed of both fibrils and flocculent material, but the membrane covering the central meniscus of Kuhnt showed very low fibrilar content, and mainly consisted of flocculent material.…”

Interchange of fluid between the optic nerve and the vitreous cavity in the pig is facilitated by fenestrations of varied sizes in the basal membrane and preferential flow routes through the prelaminar tissue. Preferential flow routes exist in the extracellular spaces of Elschnig and Kuhn' astrocytes and give a sharply distinct image when compared with flow through zones in which astrocytes envelope axons. Escape routes may be instrumental in preventing oedemas of the optic nerve head, but they could also serve as entrance doors for fluids from the vitreous and aqueous and play a pathogenic role in ageing and glaucoma.
