Does experimental nonenzymatic glycosylation of vitreous collagens occur by two pathways?
Nonenzymatic glycosolation of vitreous collagen can occur not only by the classic nonoxidative pathway, but also by a second oxidative pathway that is susceptible to a number of inhibitors.
ORO is distinctly uncommon without sinonasal inflammation or previous surgery. Isolated unilateral ORO raises suspicion for an underlying neoplasm or cephalocele and warrants further evaluation.
