Pathophysiology of Anomalous PVD
Sep 1 2020 by J. Sebag, MD, FACS, FRCOphth, FARVO
This unifying concept of vitreo-retinopathies hypothesizes that the pathogenesis of several vitreoretinal diseases that were previously considered very disparate, are actually all manifestations of the same underlying pathophysiology – anomalous PVD. Note that vitreo-papillary adhesion (VPA) and traction can cause primary optic neuropathy, but might also play a role in facilitating/promoting cell migration and proliferation during pathologic neovascularization of the optic disc. Further, VPA seems to alter the vector of tangential forces exerted by a membrane, in some cases full-thickness posterior vitreous cortex and in some cases the outer layer of the posterior vitreous cortex left attached to the macula after vitreoschisis. While not all cases of macular holes have vitreoschisis, they feature vitreomacular adhesion and traction almost always with VPA. [From Sebag J: Anomalous PVD – a unifying concept in vitreo-retinal diseases. Graefe’s Arch Clin Exp Ophthalmol 2004;242:690-8 and Sebag J, Niemeyer M, Koss M: Anomalous PVD and vitreoschisis.

Traumatic Giant Retinal Tear Associated Retinal Detachment
Nov 9 2019 by Luis J Haddock, MD
This wide field fundus photograph of the left eye shows a traumatic giant retinal tear associated with total retinal detachment. The image shows the torn superior retina folded over the macula with the underside of the retina visible. There is associated peripheral choroidal detachment due to hypotony from giant retinal tear. This patient has history of spondyloepithelial dysplasia with dwarfism and presented with vision loss after a recent blunt trauma with elbow to the eye.

Acute Compressive Optic Neuropathy
Jun 1 2019 by John S. King, MD
84-year-old white female with acute loss of vision in the left eye one day ago was sent here after going to the ED per primary eye provider. She described vision loss as a grey curtain that became total darkness. She had left sided temporal tenderness and some left sided neck pain. In the ED the cardiac work-up was u/r, the ESR and CRP were normal, and the CTH showed some non-specific opacification in the L ethmoid sinus. Acuity was HM OS with RAPD, normal EOMs, no proptosis or ptosis, posteriorly no SVPs were noted; the optic discs were pink and flat; no emboli or retinal whitening present; some bear tracks located nasally (see photo). She was referred to Dr. Doyle, who ordered an MRI, which showed a large mucocele with bony erosion into the left orbit, along with some ON enhancement possibly from compression (see images). She was operated that night and later recovered to 20/40 in that eye with a residual, inferior arcuate scotoma.
