BACKGROUND The "Early Treatment for Retinopathy of Prematurity Cooperative" reported a failure rate of 55.2% using laser in zone 1 for treatment of retinopathy of prematurity (ROP). We need to offer better alternatives for those patients. We undertook this study to evaluate the efficacy of combined laser-ranibizumab therapy for ROP with(More)
BACKGROUND We undertook this study to determine the prevalence of premature retinopathy in a third level care hospital. METHODS We carried out a descriptive, observational, longitudinal and prospective study from March 1991 to February 2004, including newborns with low birthweight of <1500 g and <35 weeks of gestation, evaluating the peripheral retina(More)
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(More)
PURPOSE To demonstrate the effectiveness of botulinum toxin for treating strabismus secondary to systemic diseases. MATERIAL AND METHODS 141 patients with secondary strabismus were studied. To reduce risks, the treatment with botulinum toxin was made by a direct technique proposed by the authors. The response to the treatment was classified according to(More)
BACKGROUND A review of neuronal and psychomotor alterations related to delay of amblyopia treatment was carried out. METHODS We reviewed various studies to explain the anomalies of visual cortex because of the prevalence of anomalous stimulus in patients with amblyopia. RESULTS Visual pathways are developed embryologically. The newborn has ocular(More)
BACKGROUND We undertook this study to evaluate the long-term effects of threshold retinopathy of prematurity (ROP) treatment using Argon laser under indirect ophthalmoscopy, as well as to analyze ocular diseases in those patients. METHODS This is a descriptive, observational, longitudinal and prospective study carried out from March 1991 to February 2005,(More)
OBJECTIVE Our aim was to demonstrate metabolic changes occurring in brain cortex during strabismus treatment. MATERIAL AND METHODS Single photon emission computed tomography (SPECT) of brain was made in patient with strabismus. The study only included congenital esotropia and excluded patients with other anomalies. Strabismus treatment was carried out(More)
BACKGROUND We undertook this study to demonstrate the visuomotor alterations, intelligence level and depression changes in children with recurrent strabismus. METHODS Children with recurrent strabismus were studied with the Human Figure Test, Lauretta Bender Visuomotor Test, Intelligence Level of Weschler, WISC-R, and WPPSI. Complete exploration of(More)
BACKGROUND Strabismus has been related to different alterations of brain functions and learning in children. Early treatment for visuomotor functions may improve the executive areas of intelligence. We undertook this study to demonstrate changes of visuomotor function and intelligence in children after strabismus treatment. METHODS This is a prospective(More)
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.
