Outcomes With Overlapping Surgery at a Large Academic Medical Center.

Objective: The aim of the study was to evaluate the efficiency and safety of overlapping surgery (OS) at a training institution by comparing it with nonoverlapping surgery (NO) with respect to operative time, mortality, readmissions, and complications.

Background: OS is the practice of an attending physician providing supervision to 2 surgeries that are scheduled at overlapping times. Recent media and government attention have raised concerns about this practice and the need for informed patient consent.

Multi-nucleate retinal pigment epithelium cells of the human macula exhibit a characteristic and highly specific distribution.

Background: The human retinal pigment epithelium (RPE) is reportedly 3% bi-nucleated. The importance to human vision of multi-nucleated (MN)-RPE cells could be clarified with more data about their distribution in central retina.

Methods: Nineteen human RPE-flatmounts (9 ≤ 51 years, 10 > 80 years) were imaged at 12 locations: 3 eccentricities (fovea, perifovea, near periphery) in 4 quadrants (superior, inferior, temporal, nasal).
