Bilateral duplication of the optic canals
1Department of Anatomy, Dokuz Eylül University Medical Center, Izmir, Turkey.
Summary
A rare optic canal anomaly was found in 0.54% of human skulls during an autopsy survey. This study presents anatomical findings of bilateral and unilateral optic canal duplication.
Area of Science:
- Anatomy
- Human Skull Morphology
- Ophthalmology
Background:
- The optic canal transmits the optic nerve and ophthalmic artery.
- Variations in cranial foramina can impact neurovascular structures.
- Optic canal duplication is an uncommon anatomical finding.
Purpose of the Study:
- To report the incidence and anatomical characteristics of optic canal duplication.
- To document rare variations in human skull anatomy.
Main Methods:
- Autopsy survey of 369 human skulls.
- Gross anatomical examination of skull base structures.
Main Results:
- One case of bilateral optic canal duplication (0.27%) was identified.
- One case of unilateral optic canal duplication (0.27%) was identified.
- Total incidence of optic canal duplication was 0.54%.
Conclusions:
- Optic canal duplication is a rare anatomical anomaly.
- Awareness of such variations is crucial for anatomical studies and clinical practice.
