<p>Children with Dyslexia Have Altered Cross-Modal Processing Linked to Binocular Fusion. A Pilot Study</p>
2020
Introduction The cause of dyslexia, a reading disability characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities, is unknown. A considerable body of evidence shows that dyslexics have phonological disorders. Other studies support a theory of altered cross-modal processing with the existence of a pan-sensory temporal processing deficit associated with dyslexia. Learning to read ultimately relies on the formation of automatic multisensory representations of sounds and their written representation while eyes fix a word or move along a text. We therefore studied the effect of brief sounds on vision with a modification of binocular f…
Five-year change in refractive error and its risk factors: results from the Gutenberg Health Study.
2021
Background/AimsTo examine the 5-year change in refractive error in phakic eyes and its risk factors in the general population.MethodsThe Gutenberg Health Study (GHS) is a population-based cohort study including 15 010 participants from Germany aged 35–74 years at baseline examination (2007–2012). After 5 years, a follow-up examination was carried out (83% participation). 5-year change of spherical equivalent (SE) was computed as difference between follow-up and baseline objective refraction. Linear and logistic regression analysis were conducted analysing potential risk factors. Only phakic eyes at follow-up examination were included.ResultsRight eyes of 10 175 subjects were included. An ag…
Changes in higher-order aberrations after implantation of a foldable iris-claw lens in myopic phakic eyes
2006
Purpose To evaluate the change in higher-order aberrations (HOAs) after implantation of a foldable iris-claw phakic intraocular lens (pIOL) in myopic eyes. Setting Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany. Methods This prospective nonrandomized comparative self-controlled trial included 41 eyes that had implantation of a foldable iris-claw pIOL between July 2003 and November 2004. All patient data for HOAs (Zernike coefficient) were measured and calculated using the same pupil size preoperatively and postoperatively, and the root-mean-square (RMS) wavefront error was calculated. Examinations were performed preoperatively as well as 1 week and 3, 6, and 12 m…
Evaluation of the efficacy of the ‘nasal airflow-inducing manoeuvre’ for smell rehabilitation in laryngectomees by means of the Sniffin′ Sticks test
2011
Clin. Otolaryngol. 2011, 36, 17–23 Objective: To determine the efficacy of the nasal airflow-inducing manoeuvre (NAIM) as a method for olfactory rehabilitation in laryngectomees by the means of the Sniffin′ Sticks test. Study design: Prospective open interventional trial. Setting: Tertiary academic hospital. Participants: Thirty-seven patients after laryngectomy have been screened and 25 patients have been included into the study. The participant’s sense of smell was tested with the Sniffin′ Sticks test before and after learning the nasal airflow inducing manoeuvre. The individual level of threshold, discrimination and identification (TDI) was determined and the individual threshold, di…
Síndrome de Susac de presentación ocular atípica
2007
espanolCaso clinico: Mujer de 25 anos de edad afecta de encefalopatia y perdida auditiva neurosensorial, remitida a nuestro servicio para confirmar un sindrome de Susac por presentar una disminucion de agudeza visual bilateral. En la exploracion funduscopica se aprecio una microangiopatia retiniana periferica. Discusion: El sindrome de Susac se caracteriza tipicamente por la triada encefalopatia, perdida auditiva neurosensorial, y oclusiones de ramas arteriales retinianas. En nuestro caso las alteraciones oculares eran atipicas, apreciandose amputacion de vasos terminales con cumulo de microaneurismas en retina periferica de ambos ojos.

Retinal vein occlusion: current treatment.
2010
Retinal vein occlusion (RVO) is a pathology noted for more than 150 years. Although a lot has been written on the matter, it is still a frequent condition with multifactorial etiopathogenesis with many unclear aspects. The RVO pathogenesis has varied systemic and local implications that make it difficult to elaborate treatment guidelines. The management of the patient with RVO is very complex and a multidisciplinary approach is required in order to identify and correct the associated risk factors. Laser therapy remains the gold standard in RVO, but only modest functional improvement has been shown in branch retinal occlusion forms. Multicenter studies of intravitreal drugs present them as a…
The role of fissula ante fenestram in unilateral sudden hearing loss
2016
The cause of unilateral sudden sensorineural hearing loss (SNHL) remains unclear in many clinical cases. Perilymphatic leakage through a fissula ante fenestram (FAF) fistula is one possible reason. We present four clinical cases with proven FAF fistula, discovered during surgical exploration. All patients experienced partial hearing recovery after surgical coverage of the fistula. We suggest FAF as a possible site for perilymphatic leakage, representing an anatomical correlate for sudden unilateral SNHL. We recommend early exploratory tympanotomy with special attention to the bony region, anterior to the oval window, in cases of severe sudden SNHL and suspected FAF.
Abnormal Linguistic Lateralization and Sensory Processing in High Functioning Children with Autism Spectrum Conditions
2014
Brain lateralization for language in high-functioning children with autism spectrum conditions (ASC) and sensory processing were explored as a part of a neuropsychological profile. A dichotic listening test and the Luria laterality subtest were administered to all participants (including controls) and the sensory profile test only to the ASC group. The usual right ear advantage was not exhibited by children with ASC and anomalies in auditory filtering were found. The sensory profile of 60% of the sample was characterized by hypersensitivity to auditory stimuli, hyposensitivity to vestibular information, high emotional reactions to sensory experiences, poor psychosocial coping strategies, hi…
Efectos de la estimulación sensorial en la conducta adaptativa del alumnado con TEA: un estudio de caso
2019
INTRODUCCIÓN: Las personas con trastorno del espectro autista (TEA) presentan habitualmente dificultades para procesar e integrar la estimulación sensorial de su entorno. Estas dificultades pueden verse reducidas con la intervención adecuada, especialmente en edades tempranas. El objetivo de este trabajo es evaluar los efectos que produce un programa de estimulación sensorial sobre la conducta y la inclusión educativa de un niño con TEA de educación primaria. MÉTODO: Se presenta un estudio de caso con un participante de 7 años con diagnóstico de TEA. La intervención ha constado de 52 sesiones de estimulación sensorial diseñada de acuerdo al perfil sensorial del participante. La efectividad …
