Naranjo Teresita de Jesús Méndez Alejandro Arias Medicina Cuba squint vision surgery Esotropia INTRODUCTION Congenital esotropia is a convergent deviation of the eyes when fixating on an object. It appears during the fi rst six months of life and affects muscle structure and physiology, as well as the relation of the eyes with the environment, retinal relations and neu- ral integration phenomena. Amblyopia develops in 30–50% of those affected. Timely surgery is effective in most cases. OBJECTIVE Describe surgical results in congenital esotropia cases treated in the Pediatric Ophthalmology and Strabismus Service of the Ramon Pando Ferrer Ophthalmology Institute in Havana between January 2008 and May 2009. METHODS A descriptive, retrospective study was carried out through review of 127 cases (aged 1–18 years, 55 male and 72 female) op- erated on for congenital esotropia between January 2008 and May 2009. Variables used were: age at surgery, degree of preoperative amblyopia, type of fi xation, refractive error, associated conditions, type of surgery performed and pre- and postoperative deviation angles. RESULTS The largest number of congenital esotropia cases were found in children <2 years old (38.6%). Before surgery, 37% of cases studied showed mild amblyopia; 22.8% moderate and 12.6% severe; 27.6% did not cooperate with visual acuity testing. With respect to fi xation: 91.3% showed central fi xation and 8.7% eccentric. Refrac- tive errors found were: mild hyperopia (65.4%), moderate hyperopia (29.1%), and myopia (5.5%). Associated conditions were: overac- tion of the inferior oblique muscles (48%), latent nystagmus (16.5%), and dissociated vertical deviation (8.7%); no alterations were found in 26.8% of cases. The most frequently used surgical treatment was bilateral medial rectus muscle recession (92.1%). The most common preoperative deviation angle range was 31–40 prism diopters (PD) in 51.9% of patients; the postoperative deviation angle most commonly found after 12 months was <10 PD in 64.6% (orthotropia). CONCLUSIONS Surgery, most commonly with medial rectus muscle resection, was effective in correcting congenital esotropia. 2011 artículo científico 1555-7960 https://www.redalyc.org/articulo.oa?id=437542077006 en http://www.redalyc.org/revista.oa?id=4375 MEDICC Review application/pdf Medical Education Cooperation with Cuba MEDICC Review (Estados Unidos de América) Num.1 Vol.13 |
