Thick, Adherent and Whitish Posterior Hyaloid: What is it?

RETINA PHOTO_Natalia Ferreira Few conditions are associated to thickening of posterior hyaloid membrane. Familial amyloidotic polyneuropathy (FAP) is characterized by systemic accumulation of mutant amyloigogenic transthyretin in different tissues, the eye included. FAP has peculiar ocular manifestations. Deposition of amyloid in vitreous cavity is a frequent one. Vitreous amyloid deposits (around collagen) are characteristic whitish and...

Viewing and Illumination of the Vitreous Base

Author: Anselm Jünemann, Erlangen, Germany Problem: Complete vitrectomy at the vitreous base is a precondition for successful vitreoretinal surgery. Controlled and save shaving of the vitreous base requires sufficient illumination and indentation for viewing. Using conventional illumination indentation has to be performed by an assistant. Approach: There are different approaches to achieve the visualisation of the vitreous base. The...

Evolving Concepts in Pharmacologic Vitreolysis

Brooks W. McCuen, II, MD (Durham, NC) The attachment of the cortical vitreous to the inner limiting lamina of the retinal surface plays an important role in the pathophysiology of many vitreoretinal diseases, such as idiopathic macular hole, vitreomacular traction syndrome, penetrating ocular trauma and proliferative diabetic retinopathy. Despite continued improvement in techniques and instrumentation, achieving an atraumatic cleavage of...

The Use of New Surgical Strategies in Dealing with Ocular Trauma

Giampaolo Gini, MD (Prato, Italy), Vincent S. Reppucci, MD (New York, NY) SYNOPSIS New techniques and devices are helping us deal successfully with complex trauma cases. Drainage implants have proved reliable where no other option for controlling IOP is available. Posterior hyaloid identification with Triamcinolone and its consequent removal accounts for fewer mid- and long-term retinal complications. Finally, the laser-assisted corneal...
