Retrobulbar anesthesia and retinal vascular obstruction

Area of Science:

• Ophthalmology
• Surgical Complications
• Neuro-ophthalmology

Background:

• Retrobulbar anesthesia is a common procedure for ophthalmic surgeries.
• Complications, though rare, can significantly impact vision.
• Understanding the pathophysiology of these complications is crucial for patient outcomes.

Observation:

• Three cases of combined central retinal artery/vein obstruction following retrobulbar anesthesia are presented.
• Obstruction onset varied, with one immediate and two delayed cases.
• Imaging revealed dilated optic nerve sheaths, suggesting intravaginal hemorrhage.

Findings:

• Combined central retinal artery and vein obstruction is a potential complication of retrobulbar anesthesia.
• Intravaginal optic nerve sheath hemorrhage is implicated as the underlying cause.
• Surgical intervention (orbitotomy with optic nerve sheath decompression) may lead to partial visual recovery.

Implications:

• This study highlights a rare but serious complication of retrobulbar anesthesia.
• Early recognition and intervention may improve visual prognosis.
• Further research into preventative measures and optimal management strategies is warranted.
