Arytenoid repositioning device.

Objectives: We report development of a device and technique to manage laryngeal paralysis through minimal-access arytenoid adduction (for unilateral paralysis) and arytenoid abduction (for bilateral paralysis).

Methods: A human cadaver study coupled with directed engineering was used to develop instrumentation designed to secure the muscular process of the arytenoid into favorable adducted or abducted positions. Digital video, photography, and 3-dimensional computed tomographic (CT) imaging of cadaveric larynges were done to evaluate the surgical technique.

Choriocapillaris vascular dropout related to density of drusen in human eyes with early age-related macular degeneration.

Purpose: Age-related macular degeneration (AMD) is a common, potentially blinding disease characterized by the presence of extracellular deposits beneath the retinal pigment epithelium (RPE). Choroidal vascular changes have also been noted in AMD. This study examined the relationship between the choroidal vasculature and extent of drusen and other sub-RPE deposits, the key pathologic landmarks of AMD.
