Ultra wide field fundus photograph of a 41-year-old male with a dislocated lens affecting his right eye. IOL noted inferior vitreous base and vitrectomy surgery for removal of IOL was recommended. Patient has history of retinitis pigmentosa as well. Patient's vision at the time of presentation was counting fingers at 2 feet.

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.

This is an aphakic retinal detachment in a 66-year-old woman. Note the prominent yellow line which probably represents the posterior border of the vitreous base. Near the left end of the line there is a small retinal flap. At the exact location of this flap, there is a sudden break in the continuity of the yellow line, which is an important clue in finding this retinal tear. Often in aphakic detachments the causative tear is smaller than the one shown here and can be identified only by seeing a filamentous strand interrupting the uniform yellow line of the vitreous base.

KR is a 25 year old white female who presented with a one month history of floaters OD. Past ocular and systemic history were unremarkable. On clinical examination, the visual acuity was 20/20 OU, and the anterior segments were normal. There was a very mild degree of vitreous cell OD, though no cystoid macular edema nor vasculitis. A lobulated white mass was noted overlying the vitreous base inferotemporally OD (thickness 3.3mm). There was no calcification, though prominent cysts were noted on the surface of the lesion. A fluorescein angiogram, echogram, and CT scan were obtained, along with a thorough systemic evaluation.

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).

This small elevated peripheral retinal lesion in a 48-year-old woman is a cystic retinal tuft. Such tufts are congenital developmental anomalies present from birth and situated behind the vitreous base. They are sites of abnormal vitreoretinal attachment, and can occasionally lead to retinal tears at the time of posterior vitreous detachment. They are present in about 5% of patients.

This is a retinal detachment in a 55-year-old man. The vertical convex line on the right side probably represents the posterior border of the vitreous base. Note the small tractional tear with the base of its flap attached at this line. This demonstrates how the vitreous base presents an effective barrier to further extension of the retinal tear. Note also how the flap breaks the continuity of the yellow line.
