II. Indication
III. 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
IV. Findings: Normal response
V. Findings: Abnormal - Afferent lesion (Marcus Gunn Pupil)
- Causes
- Retinal lesion
- Optic Nerve lesion
- 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
VI. Findings: Abnormal - Efferent lesion (CN 3 or pupillary muscle)
- Affected eye loses consensual and Direct Light Reflex
- Unaffected eye maintains consensual and direct reflex
