Summary
Spinal manipulation therapy may resolve vision loss caused by optic nerve microischemia. This therapy potentially addresses cerebral microvascular spasms, offering a new treatment avenue for interictal migraine.
Area of Science:
- Neurology
- Ophthalmology
- Integrative Medicine
Background:
- Quantitative static perimetry is a valuable tool in assessing visual field defects.
- Spinal manipulation therapy (SMT) is increasingly explored for non-musculoskeletal conditions.
Observation:
- A patient presented with transient bilateral visual field loss, resolving after SMT.
- Subsequent quantitative static perimetry revealed a persistent uniocular visual defect.
- No ocular or neurological pathology explained the visual defect, suggesting optic nerve microischemia.
Findings:
- The uniocular scotoma (visual field defect) resolved immediately with SMT.
- The visual defect recurred twice, each time resolving promptly with SMT.
- This suggests SMT can influence cerebral microcirculation.
Implications:
- SMT may alleviate microvascular spasms in cerebral arteries, even those not directly linked to the spine.
- Interictal migraine, associated with prolonged cerebral microcirculation changes, is a potential target for SMT.
- This case highlights SMT as a potential treatment for certain types of visual disturbances and migraine-related phenomena.
