ABSTRACT
Objetivo: Analizar las posibilidades de diagnóstico y tratamiento en pacientes con skew deviation (SD) o estrabismo con desviación oblicua. Material y métodos: Estudio prospectivo, observacional y longitudinal de pacientes con SD, de septiembre de 2007 a mayo de 2008. Se realizó exploración estrabológica, estudio multidisciplinario y se evaluaron alternativas terapéuticas. Resultados: Se estudiaron 10 pacientes con SD. Edad 11.5 + 13.6 años. Los diagnósticos neurológicos fueron esclerosis múltiple, malformación arteriovenosa, epilepsia, hidrocefalia, encefalopatía isquémica, atrofia cortical, hipoplasia de cuerpo calloso y hemorragia talámica. Se encontró retraso psicomotor en 80 %, además se asoció a apraxia de Cogan, síndrome de Parinaud, nistagmo en see-saw, síndrome de Foville y hemiplejía. Los estrabismos relacionados fueron exotropía en cinco, endotropía en tres, hipertropía en dos, desviación vertical disociada en uno. Se encontró lesión a II, III y VII nervios craneales. Conclusiones: El estudio estrabológico adecuado permite un mejor diagnóstico de la lesión en SD y con ello vigilar la evolución neurológica del paciente. El tratamiento debe incluir la rehabilitación óptica y el manejo del estrabismo, principalmente con toxina botulínica.
BACKGROUND: We undertook this study to analyze diagnostic and treatment alternatives in patients with skew deviation (SD). METHODS: This is a prospective, observational and longitudinal study of patients with SD. The study took place in a third-level medical center during the period from September 2007 to May 2008. Strabismological exploration, multidisciplinary diagnosis and treatment alternatives were analyzed. RESULTS: Ten patients presenting SD were studied. Diagnoses were multiple sclerosis, arteriovenous malformation, epilepsy, hydrocephalus, ischemic encephalopathy, cortical atrophy, hypoplasia of corpus callosum and thalamic hemorrhage. Psychomotor retardation was present in 80%. Other diagnoses were Cogan apraxia, Parinaud syndrome, see-saw nystagmus, Foville syndrome, and hemiplegic alterations. Related strabismuses were exotropia (5), esotropia (3), hypertropia (2), and dissociated vertical deviation (1). Lesions of II, III and VII cranial nerves were found. CONCLUSIONS: Complete strabological study allows a better diagnosis of the lesion and consequently relapsing disease in order to achieve a better treatment according to each patient. Optical rehabilitation and botulinum applications are especially indicated.

Las distrofias en patrón son patologías de la retina genéticamente determinadas que se caracterizan por anormalidades en el epitelio pigmentario que se visualizan en el fondo de ojo conformando diversos patrones de puntos o líneas. Realizamos una revisión detallada de las diversas variedades de presentación y sus características más importantes, e incluimos una secuencia fotográfica de las más representativas.
Pattern dystrophies are defined as a group of diseases genetically determined and characterized by pigment epithelium changes that are seen on fundus examination, such as various line and dot patterns. We present a review of these pathologies including a comparative table reporting the main characteristics as well as some representative figures of each one in order to facilitate diagnosis.

BACKGROUND: We undertook this study to demonstrate the incidence of vitreoretinal dystrophies in a Mexican population. METHODS: This was a retrospective, observational, descriptive, transverse study. We analyzed the files of patients treated at the Retina Department of a medical center for state employees (ISSSTE) from January 1991 to December 2006 to obtain the incidence of vitreoretinal dystrophies. RESULTS: We studied 36,300 patient files. We found an incidence of 0.008% for familial exudative vitreoretinal dystrophy, 0.008% for X-linked juvenile retinoschisis, 0.005% for Wagner disease and 0.005% for Goldmann-Favre disease. We present here a representative case of each type of dystrophy. CONCLUSIONS: Vitreoretinal dystrophies are uncommon diseases and are difficult to diagnose. Even though their incidence is low, the poor evolution to blindness requires identification of early signs in order to offer timely and opportune treatment.
