Summary
Rectus muscle trauma can occur during cataract surgery with sub-Tenon's anesthesia. Surgeons should carefully identify the injection site to prevent complications like double vision.
Area of Science:
- Ophthalmology
- Surgical Complications
- Anesthesia
Background:
- Phacoemulsification cataract extraction with intraocular lens implantation is a common procedure.
- Sub-Tenon's local anesthesia is frequently used for this surgery.
- Potential complications of local anesthesia techniques require careful consideration.
Observation:
- This study reviewed three cases of rectus muscle trauma.
- Patients underwent phacoemulsification cataract extraction and intraocular lens implantation under sub-Tenon's anesthesia.
- The inferonasal quadrant was the injection site in all cases.
Findings:
- Two patients experienced vertical diplopia due to inferior rectus muscle restriction.
- One patient developed horizontal diplopia from medial rectus muscle restriction.
- Surgical exploration confirmed rectus muscle involvement in all cases.
Implications:
- Rectus muscle trauma is a potential complication of sub-Tenon's anesthesia.
- Careful identification of the sub-Tenon's space is crucial during anesthetic injection.
- This highlights the need for surgical precision to avoid ocular muscle injury.
