Comparison of one-injection-site peribulbar anesthesia and retrobulbar anesthesia

One hundred patients having elective cataract surgery were evaluated in a prospective, randomized, double-blinded study comparing retrobulbar and peribulbar anesthesia. Patients were divided into two study groups and evaluated on three criteria felt to be critical to intraocular surgery. Results showed that the efficacy of the one-injection-site peribulbar block was similar to that of the retrobulbar block for all three criteria. Because the one-injection-site anesthetic is administered outside the muscle cone, the potential for optic nerve and central nervous system complications should be minimized.     

Posterior peribulbar anesthesia: an alternative to retrobulbar anesthesia

Peribulbar anesthesia is a safe alternative to retrobulbar anesthesia for ophthalmic surgery. Because the anesthetic is deposited outside the muscle cone, the potential for intraocular or intradural injection is greatly minimized. Furthermore, intraconal hemorrhage and direct optic nerve injury is avoided. We illustrate the details of our technique for posterior peribulbar anesthesia and describe our experience in over 3,000 cases.

Congenital corneal anesthesia related to trigeminal anesthesia: case report

Corneal anesthesia is a rare condition, therefore its diagnosis is frequently impaired or it is not noticed during the anterior segment examination. Case report of a 18-year-old patient referred to our Corneal and External Disease Department who complained of dry eye symptoms and with a suspicion of Sj?gren's syndrome. She had amblyopia of the right eye, consequence of corneal leucoma over the visual axis secondary to a fingernail traumatism inflicted by herself in childhood. On the ophthalmologic examination corneal sensitivity was absent in both eyes. Severe dry eye and breakup time less than four seconds. Diagnosis of congenital corneal anesthesia was established, secondary to trigeminal anesthesia found on neurological evaluation of facial sensitivity. She also showed sudden movements of the chin which evidenced sensorial pathology of the trigeminal nerve. The general ophthalmologist and specially anterior segment specialists must perform tests for corneal sensitivity during the routine eye examination.
