Posterior reversible encephalopathy syndrome (PRES) can cause temporary vision loss after spinal surgery. Prompt diagnosis and treatment lead to complete vision recovery in patients.
Area of Science:
- Neurology
- Ophthalmology
- Neurosurgery
Background:
- Posterior reversible encephalopathy syndrome (PRES) is a rare neurological complication.
- It can manifest as temporary postoperative visual loss (POVL) following spinal deformity surgery.
Observation:
- Two patients developed PRES after complex spinal surgeries.
- Symptoms included confusion and bilateral visual loss, occurring 7 and 15 days postoperatively.
- Both patients had underlying conditions necessitating extensive spinal fusion.
Findings:
- PRES was diagnosed in both patients presenting with POVL.
- Medical management of PRES resulted in complete visual recovery for both individuals.
- The syndrome was linked to spinal deformity correction procedures.
Implications:
- Highlights PRES as a critical differential diagnosis for POVL after spinal surgery.
- Emphasizes the importance of timely PRES diagnosis and intervention.
- Suggests that prompt management ensures favorable patient prognosis and visual outcomes.
