ABSTRACT
There is substantial national and international variation in the conduct of anesthesia for ophthalmic surgical procedures. Ophthalmic regional anesthetic techniques include traditional needle-based blocks, such as intraconal or extraconal injections; sub-Tenon's blocks which can be accomplished with needles, but are more commonly performed with blunt cannulae; and topical anesthesia. Needle-based techniques are generally safe although rare, serious sight- and life-threatening complications may occur. In recent years, a renewed interest in sub-Tenon's and topical anesthesia has emerged. Currently there is no absolutely safe ophthalmic regional block. It is essential that those who are involved in the care of ophthalmic patients have a thorough knowledge of the approaches employed and their associated risks and benefits. This review article outlines the relevant anatomy, commonly used techniques and their safe performance.

We describe a girl with eosinophilic cellulitis (Wells syndrome) in whom the disease appeared immediately after birth with subcutaneous nodules on the scalp and trunk, followed by the characteristic skin swelling and erythema at the age of 6 months. The lesions disappeared after a few weeks, but recurred several times. The mother had consumed large quantities of medications during the pregnancy, including iron, vitamins, and "natural remedies." Based on time of onset, this may be regarded as a unique case of congenital Wells syndrome. Its relation to the medications taken by the mother remains speculative. Subcutaneous nodules may be the presenting sign of Wells syndrome in children.
