Here are a number of useful links to help you manage eye problems in the Emergency Department (ED), but first the basics.

The Basics

The vital sign for the eye is the measurement of visual acuity (VA). Just as you would measure pulse rate, blood pressure, respiratory rate and O2 saturations for a resuscitation or neurovascular integrity of a limb you must do the VA at the outset. VA measurement must be taken before you do anything or apply anything to the eye.
