Effect of peripapillary vitreous opacity on retinal nerve fiber layer thickness measurement using optical coherence tomography.

multiple topical agents for control of the intraocular pressure in her left eye. Analysis of Explanted NewColorIris Implant. Analysis using both light and scanning electron microscopy of one of the explanted NewColorIris devices shows surface and edge characteristics that deviate significantly from the appearance of other currently US Food and Drug Administration–approved anterior chamber implants on scanning electron microscopy. Specifically, the posterior surface of the NewColorIris implant has an irregular surface architecture and the edge has a very rough, nearly serrated appearance on close examination (Figure 3). These morphologic features support our contention that the surface characteristics of the NewColorIris contributed to ocular inflammation, secondary glaucoma, and endothelial cell loss in both patients. The edge profile appears to have been particularly deleterious to patient 2 due to direct apposition of the device against the angle structures as demonstrated by OCT.
