* What is first?
* What do you stain the eye with?
* Look for what type of sign?
* Why do you do slit lamp exam?
* _ Testing

A
  • Visual acuity first
  • Stained exam with fluorescein and tetracaine
  • Look for Seidel sign – bleb leakage indicates perforation
  • Slit lamp exam-> look at posterior eye
