Abstract:
We herein describe 12 patients who suffered penetration or perforation of the globe during injection of a local anesthetic before cataract surgery. Minimum follow-up was 6 months. Six eyes had a final visual acuity of 20/50 or better and an attached retina. Four eyes had an attached retina with a visual acuity of 20/80 to 2/200. Two eyes were anatomic failures because of a recurrent retinal detachment complicated by proliferative vitreoretinopathy. These cases show that retinal penetrations without retinal detachment may be treated effectively with photocoagulation. Vitreous surgery is recommended when the retinal penetration is associated with a retinal detachment. Eyes with a dense vitreous hemorrhage and a suspicion of a penetrating injury should either be followed up closely with echography or should undergo vitreous surgery since the extent of the injury cannot be determined.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
