Pupillary Light Reflex
Aka: Pupillary Light Reflex, Swinging Flashlight Test, Marcus Gunn Pupil, Direct Light Reflex, Consensual Light Reflex, Direct Light Pupillary Reflex Loss, Relative Afferent Pupillary Defect, Afferent Pupillary Defect, Pupil Reactivity- Indication
- Technique
- Check left eye response (direct and consensual)
- Shine light on left eye and check left pupil reflex
- Shine light on right eye and check left pupil reflex
- Check right eye response (direct and consensual)
- Shine light on right eye and check right pupil reflex
- Shine light on left eye and check right pupil reflex
- Check left eye response (direct and consensual)
- Findings: Normal response
- Findings: Abnormal - Afferent lesion (Marcus Gunn Pupil)
- Causes
- Retinal lesion
- Optic Nerve lesion
- Ischemic Optic Neuropathy
- Multiple Sclerosis
- Findings
- No pupil response to direct light
- Intact Consensual Light Reflex
- Paradoxical Pupil Dilation to direct light
- Occurs on moving light from opposite to affected eye
- Causes
- Findings: Abnormal - Efferent lesion (CN 3 or pupillary muscle)
- Affected eye loses consensual and Direct Light Reflex
- Unaffected eye maintains consensual and direct reflex
