Dark-field slit microscopy was performed on fresh, unfixed, post-mortem human eyes that had undergone dissection to peel off the sclera, choroid, and retina. The vitreous body remains attached to the anterior segment which is seen below, while the posterior pole is above in these images. The top panel demonstrates the absence of internal vitreous structures that scatter light in youth (left image from an 11 year-old girl, right image from a 14 year-old boy. The middle panel demonstrates light scattering from linear, fibrous structures that have an antero-posterior orientation with insertions into the vitreous base peripherally and the posterior vitreous cortex, typical in middle age (left image from a 56 year-old and right image from a 59 year-old). The bottom panel illustrates advance fibrous liquefaction in old age (88-year-old subject). [From Sebag J, Niemeyer M, Koss M: Anomalous PVD and vitreoschisis. In: Vitreous – in Health & Disease (J.

The vitreous is attached and demonstrates after-movements of formed vitreous as the patient is asked to look to the right and left. There is mild reflectivity in the formed vitreous from collagen. The optic nerve is visible in the superior aspect of the image and the lateral rectus muscle is seen inferiorly.

Dark-field slit microscopy was performed on fresh, unfixed, post-mortem human eyes that had undergone dissection to peel off the sclera, choroid, and retina. The vitreous body remains attached to the anterior segment which is seen below, while the posterior pole is above in these images. Left: specimen was tilted to reveal the posterior aspect of the lens (L) and the fibers of the vitreous base (arrow) splayed out to insert anterior and posterior to the ora serrata; Right: Anterior Loop of the vitreous base (see text).

The sclera, choroid and retina were peeled off the vitreous body which remains attached to the anterior segment in this 9 month-old child. Due to this young age, the vitreous body maintains its solid gel structure in spite of being situated on a surgical towel (blue) in room air.
