INTRODUCTION: Bupivicaine has been shown to stimulate ocular muscle structure and length after injection into ocular muscles. Bupivicaine 0.75% has been utilized in the treatment of strabismus to alter ocular alignment by strengthening an ocular muscle. This study is designed to report 5-year follow-up outcomes after bupivicaine injection. METHODS: A retrospective chart review of all bupivicaine treated strabismus patients with symptomatic intermittent exotropia of the convergence insufficiency type (CIXT) from 2009 through 2016...

BACKGROUND: Convergence insufficiency (CI) is not an uncommon entity but seems to be an ill-defined diagnosis that incorporates many near-vision symptoms. The current literature often varies in its criteria for diagnosis. Without a clear definition and standardization of the clinical examination, there is the potential for misdiagnosis and/or the inclusion of other diagnoses as CI. The purpose of this study was to assess the uniformity of diagnostic criteria in a well-defined practice environment...
