Study Notes
Pupillary Light Reflex
- Pupil dilation in response to light is abnormal.
- Pupil constriction in response to light is normal.
- This is a normal response to light, showing PERRLA (Pupils Equal, Round, React to Light and Accommodation) is intact.
Accommodation
- Accommodation is the eye's adaptation to keep focus on a moving object.
- Pupils constrict and eyes converge.
- Convergence means the eyes move closer together (think cross-eyed).
- Normal response includes pupillary constriction and convergence of eyes.
