[Temporary amaurosis from retrobulbar lidocaine injection in late glaucoma patients]

Temporary amaurosis occurred after retrobulbar injection of lidocaine in 12 cases of antiglaucoma surgery in 4 years, and 10 of the patients were of late glaucoma. Lidocaine has a strong penetration potential which blocks the visual pathway, particularly for late glaucoma eyes in which the remnant optic nerve fibers may be especially sensitive to the drug. Therefore, the authors refrain from retrobulbar lidocaine in late glaucoma patients.
