Retrobulbar hemorrhage after sub-Tenon's anesthesia

Area of Science:

• Ophthalmology
• Surgical Complications

Background:

• Cataract surgery is a common procedure.
• Sub-Tenon's anesthesia is a standard technique.

Observation:

• A patient developed retrobulbar hemorrhage.
• This occurred after uneventful infranasal, sub-Tenon's anesthesia.

Findings:

• This case represents the first reported instance of retrobulbar hemorrhage following this specific anesthetic approach.
• The complication arose despite an otherwise uneventful procedure.

Implications:

• Highlights the importance of vigilance for potential complications even with routine procedures.
• May inform anesthetic technique selection and patient monitoring protocols for cataract surgery.
