Summary
Bilateral ischemic optic neuropathy is a rare surgical complication. This study highlights two cases following hip replacement, identifying anemia and hypotension as probable risk factors.
Area of Science:
- Ophthalmology
- Neurosurgery
- Anesthesiology
Background:
- Ischemic optic neuropathy (ION) is an uncommon but serious complication following surgical procedures.
- Bilateral and simultaneous ION is exceptionally rare, posing a significant diagnostic and management challenge.
Observation:
- This report details two distinct cases of patients experiencing bilateral and simultaneous ION post-elective total hip replacement.
- Both patients presented with sudden, severe visual deficits affecting both eyes concurrently.
Findings:
- Anemia and hypotension were identified as the most probable contributing risk factors in both presented cases.
- The surgical context of total hip replacement appears to be a potential trigger for this rare complication.
Implications:
- Highlights the critical need for vigilant perioperative monitoring of hematologic and hemodynamic parameters, especially in patients undergoing major orthopedic surgery.
- Suggests that proactive management of anemia and hypotension may be crucial in preventing ION in susceptible surgical populations.
- Underscores the importance of considering ION in the differential diagnosis of sudden visual loss after surgery.
