Perrla: Pupils equal, round & reactive to light & accommodation

According to several articles Perrla is no longer used. Doctors don't find it valuable (Riley, 2007). According to Levin (2007) there are perils to using Perrla. Levin says "PERRLA is not only incorrect and inexact—it is also, more seriously, incomplete."
