Lack of Public Awareness and Prehospital Care in Severe Trauma Patients: The Weakest Link in the Indian Healthcare System.

Introduction: Management of trauma involves both in-hospital and prehospital care. The level of prehospital care plays a vital role in trauma management. Low- and middle-income countries are still in the nascent stages of development of their emergency medical services (EMS) systems.

Spatial compression and adaptation with the low vision telescope.

Purpose: Geometrical analysis of monocular visual information specifying distance shows that a low vision telescope compresses optically specified distances by a factor about equal to its magnification. Using a group of eight visually healthy adults, we investigated the initial perceptual effect of putting on a 2x Galilean telescope and the adaptation produced by wearing the telescope.

Methods: Viewing was monocular, and the environment was only visible through the telescope.
