Q

when is the finger counting or hand motion perception test used? if this fails, what other tests come next?

A
  • VA worse than 20/200 -> finger counting @ 3ft away or hand perception at 1-2ft.
  • if unable to detect hand motion -> determine if light perception is present
  • if unable to detect light perception -> check hx of nystagmus

Q

What test assess for afferent pupillary defect?

A

Swinging light test

( switch light back and forth between eyes every 2 seconds. if normal, pupils will constrict each time the light hits them. if one side is affected, the pupils will both remain dilated while the light is on the affected pupil)

Q

What is normal IOP? When should you NOT check IOP via tonopen?

A
  • 10-20 mmHg
  • CI if globe rupture from trauma
