Peribulbar anesthesia for strabismus surgery in adult patients.

Purpose: To evaluate the efficacy and safety of peribulbar anesthesia during strabismus surgery.

Methods: Medical records of patients undergoing strabismus surgery and peribulbar anesthesia were reviewed. The overall efficacy of peribulbar anesthesia was evaluated as requirement of supplemental peribulbar anesthesia, impossibility to perform eye muscles surgery due to inadequate efficacy of the block and peribulbar block complications that occurred up to 6 weeks postoperatively.

Echobiometric study of ocular growth in patients with amblyopia.

Background: The natural evolution toward emmetropia is governed by genetic factors, but experiments with animals have demonstrated that a feedback mechanism that depends on visual function may regulate ocular growth. We attempted to verify this hypothesis in school-age patients with amblyopia by observing the ocular growth and the refractive state in the fixating and nonfixating eye in myopia and hypermetropia. This situation simulates the animal model.
