Changes in Lateral Comitance After Asymmetric Horizontal Strabismus Surgery.

Importance: Asymmetric horizontal strabismus surgery is often performed to correct primary gaze alignment without considering the symptoms that may result from misalignment in the patient's side gaze. Surgical choices influence alignment in side gaze and may contribute to functional and social deficits.

Objective: To identify the surgical procedures associated with changes of alignment in side gaze to help inform surgical planning for patients with horizontal strabismus.

The genetic basis of incomitant strabismus: consolidation of the current knowledge of the genetic foundations of disease.

In recent years, our understanding of the genetic foundations of incomitant strabismus has grown significantly. Much new understanding has been gleaned since the concept of congenital cranial dysinnervation disorders (CCDDs) was introduced in 2002, and the genetic basis of CCDDs continues to be elucidated. In this review, we aim to provide an update of the genetic and clinical presentation of these disorders.

Histopathologic findings of eyes enucleated after treatment with chemosurgery for retinoblastoma.

Introduction: Intra-arterial chemotherapy (chemosurgery) for the treatment of retinoblastoma has been performed more than 1600 times (more than 1400 times in Japan and 200 times in New York) over the past 20 years.Despite this treatment's success some eyes cannot be saved and require enucleation. Here we report the histopathologic findings of the remaining intraocular tumor of eyes that were enucleated following treatment that included chemosurgery in New York City.

Central corneal thickness in a Puerto Rican population.

Purpose: To evaluate mean central corneal thickness (CCT) in a Puerto Rican population and to compare our findings with published mean central corneal thicknesses of white, Hispanic, and African American populations in the United States.

Patients And Methods: Volunteers at the Centro Médico, San Juan, Puerto Rico, completed a survey and participated in an eye examination, which included measurement of intraocular pressure and central corneal thickness.

Results: Of 588 Puerto Rican participants, the mean CCT was 541+/-33 microm, which is significantly thinner than the published values for white populations (P<0.
