Abstract Background In psychomotor retardation there is an abnormal development of mental, sensory and motor skills associated with ocular manifestations. There are biological and psychosocial risk factors that predispose an individual to neurological damage. From 50% to 80% of patients with strabismus retardation have special features that differentiate it from the rest of strabismus in healthy patients. Objective To determine the most common type of strabismus in patients with psychomotor reta...

Resumen Antecedentes En el retraso psicomotor hay desarrollo anormal de capacidades mentales, sensoriales o motoras, que se asocian con manifestaciones oculares. Existen factores de riesgo biologicos y psicosociales que predisponen a un individuo a dano neurologico. Del 50 al 80% de los pacientes con retraso psicomotor tienen estrabismo con caracteristicas especiales, que lo diferencian del resto de los estrabismos en pacientes sanos. Objetivo Conocer el tipo mas comun de estrabismo en pacientes...

Abstract Objective Wolfram syndrome (WS) is a severe autosomal recessive pleiotropic disease primarily characterized by the association of juvenile-onset diabetes mellitus and optic atrophy. Earlier reports have shown that a proportion of WS cases may remain unrecognized due to misdiagnosis as type 1 diabetes mellitus (T1DM). The objectives of this work were to estimate the prevalence of patients fulfilling clinical criteria for WS in a cohort of subjects diagnosed as T1DM and to identify causal...

Background: A particular feature of dissociated strabismus is that the frequency of presentation and its magnitude is variable. It is common to find that in certain examinations is very obvious, and in others not so much. To facilitate exploration some maneuvers are described: Bielchowsky’s maneuver, Bielchowsky’s phenomenon and Posner test. objective: to compare the presence and magnitude of the ocular movement in dissociated strabismusin Posner’s Test using opaque versus translucent occluders....
Background: The V pattern is caused more often by a primary overaction of inferior oblique muscles. This may or may not be related to dissociated vertical deviation. The objective of this paper is to demonstrate that the dissociated vertical deviation helps to decrease the magnitude of the V pattern. Methods: We included 30 patients from 2-41 years of age, diagnosed with overactive inferior oblique muscles, were divided into two groups: associated with dissociated vertical deviation and without ...
