Abstract

The vitreous cavity occupies four-fifth the volume of the eyeball and contains the vitreous humor or vitreous, the natural clearance of vitreous cavity or space make the stereo examination possible [1–3]. The vitreous is attached with the retina tightly in the area of optic disc, macula and vitreous base. The vitreous is shaped like a sphere with an anterior depression and attached with the lens peripherally with Wieger ligament. It is traversed by a central fluid-filled canal, called Cloquet’s canal, which represents the remnants of the course taken by the hyaloids artery that supplied the vitreous and lens in the fetal eye. The anterior end of Cloquet’s canal is condensed at the posterior pole of the lens with a width of 1–2 mm, called Mittendorf point. The posterior end is attached with the rim of optic cup, which can be seen as a translucent residual, called Bergmeister papilla, if not fully degenerated.
