Study protocol for a randomized controlled trial of the NEIVATECH virtual reality system to improve visual function in children with anisometropic amblyopia.

BACKGROUND: Interest in developing alternative methods for the treatment of amblyopia has long been a topic of interest among clinicians and researchers, as prescribed occlusion and penalization therapies do not always provide an effective response and are associated with a high risk of recurrence and non-compliance. Here, we present the protocol of a small-scale RCT to evaluate the safety and clinical efficacy of a novel VR-based system designed to provide binocular vision training to children with anisometropic amblyopia. METHODS: We aim to recruit a total of 60 children with anisometropic amblyopia aged 5-17 years with no previous treatment for amblyopia other than refractive correction from the pediatric ophthalmology units of the University Clinical Hospital of Valladolid and the Vithas Medimar International Hospital of Alicante. Children who meet the eligibility criteria and consent to participate will be randomly assigned to a three-month intervention group of 18 half-hour in-office therapy sessions with the NEIVATECH system (group A) or to a parallel group receiving 2 hours of conventional patching per day at home for the same period of time (group B). Assessments of visual function will be carried out before the intervention and at 1, 2 and 3 months, with changes in distance BCVA being the primary outcome measure to be considered. Patient safety, compliance, satisfaction and acceptance to treatment will also be assessed after therapy as other valuable outcome measures. In addition, a rsfMRI scan will be performed on a subgroup of 5 patients from each group at the pre-intervention visit and at the post-intervention visit to test the effects of both therapies on neural plasticity in the visual cortex. DISCUSSION: The NEIVATECH system has been conceived as a serious game designed to provide binocular vision training to anisometropic amblyopic children by complementing the concepts of perceptual learning, dichoptic training and gamification in an immersive VR environment. We hope that this novel approach may lead to greater improvements in vision performance than those provided so far by conventional patching in anisometropic amblyopic children. TRIAL REGISTRATION: This protocol was registered with ClinicalTrials.gov ( NCT04819386 ) on 29 March 2021.

Profile of patients who consult with internists for an osteoporosis assessment: The OSTEOMED registry.

BACKGROUND AND OBJECTIVES: Osteoporosis is considered a generalised skeletal disorder in which there is impaired bone resistance, which predisposes the individual to a greater risk of fracture. The aim of this cross-sectional study was to collect and present data on the main clinical characteristics of patients who consult medical internists in Spain. Understanding these characteristics can help in implementing action plans to improve these patients' care more effectively and efficiently. MATERIAL AND METHODS: Through an analysis of the Osteoporosis in Internal Medicine (OSTEOMED) registry, this study presents the main clinical characteristics of patients with osteoporosis who attended internal medicine consultations in 23 Spanish hospital centres between 2012 and 2017. We analysed the reasons for the consultations, the densitometric values, the presence of comorbidities, the prescribed treatment and other lifestyle-related factors. RESULTS: In total, 2024 patients with osteoporosis were assessed (89.87% women, 10.13% men). The patients' mean age was 64.1±12.1 years (women, 64.7±11.5 years; men, 61.2±14.2 years). There was no significant difference between the sexes in their history of recent falls (9.1% and 6.7%); however, there were significant differences in the daily intake of calcium from milk products (553.8±332.6mg for women vs. 450.2±303.3mg for men; p<.001) and in the secondary causes of osteoporosis (13% of men vs. 6.5% of women; p<.001). In the sample, there were 404 fractures (20%), with a notable number of confirmed vertebral fractures (17.2%, 35.6% in men vs. 15.2% in women; p<.001). A large portion of the patients did not undergo the indicated treatment and presented low levels of physical activity and sun exposure. A significant percentage of the patients presented associated comorbidities, the most common of which were hypertension (32%) and dyslipidaemia (28%). CONCLUSIONS: These results define the profile of patients with osteoporosis who attend internal medicine consultations in Spain. The results also show the multisystemic character of this condition, which, along with its high prevalence, determine that the specific internal medicine consultations dedicated to managing the condition are the appropriate place for caring for these patients.

Antecedentes y objetivo La osteoporosis se considera un trastorno generalizado del esqueleto en el que existe una alteración de la resistencia ósea que predispone a la persona a un mayor riesgo de fractura. Este estudio transversal pretende recoger y presentar las principales características clínicas de los pacientes que acuden a la consulta de los médicos internistas en España. Conocer estas características podría facilitar la puesta en marcha de planes de actuación para mejorar la atención de estos pacientes de manera más eficaz y eficiente. Material y métodos A través del análisis del registro OSTEOMED (Osteoporosis en Medicina Interna), este trabajo presenta las principales características clínicas de los pacientes con osteoporosis que acudieron a las consultas de Medicina Interna en 23 centros hospitalarios españoles entre 2012 y 2017. Se han analizado los motivos de consulta, los valores densitométricos, la presencia de comorbilidades, el tratamiento prescrito y otros factores relacionados con el estilo de vida. Resultados En total se evaluó a 2.024 pacientes con osteoporosis (89,87% mujeres, 10,13% hombres). La edad media de los pacientes fue de 64,1 ±12,1 años (mujeres, 64,7 ±11,5 años; hombres, 61,2 ±14,2 años). No hubo diferencia entre sexos en la historia de caídas recientes (9,1-6,7%), mientras que sí se apreció en la ingesta diaria de calcio de lácteos (553,8 ±332,6mg en mujeres vs. 450,2 ±303,3mg en hombres; p <0,001) y en causas secundarias de osteoporosis (13% de hombres vs. 6,5% de mujeres; p <0,001). En la muestra se observaron un total de 404 fracturas (20%) (AU)

[Functional improvement after vision rehabilitation in low monocular vision after myopic macular degeneration and retinal detachment]. / Mejora funcional tras la rehabilitación visual en una paciente con visión monocular deficitaria debido a degeneración macular miópica y desprendimiento de retina.

PURPOSE: We present a case of a 62 year-old woman, with a single eye functional vision (VA of 0.16) who improved her vision after following a vision rehabilitation program, which included optical and non-optical devices for daily performance. CONCLUSIONS: A correct optometric evaluation and a training program are key factors to improve quality of life in low vision patients, whose ocular pathology allows no other treatment.

PURPOSE: To verify the efficacy a treatment for the rehabilitation of vision in our Unit for Clinical Low Vision in the testing of improvements in patient's efficiency for daily life activities. MATERIAL AND METHOD: 80 patients were studied. Ophthalmologic and optometric evaluation followed by a customised vision rehabilitation program were performed according to patient's immediate needs. In a second stage a telephoned questionnaire was filled in order to record efficacy of prescribed visual aids in their own environment. RESULTS: Rehabilitation training resulted in 89% of patients showing improvement in their quality of life in both fields; functional and psychological. 85% of patients showed improvement in near activities and 35% in far activities. DISCUSSION: A correct and specialised low vision refraction and a posterior vision rehabilitation training in the use of optical and non optical aids show increase in quality of life in patients with severe visual deficiencies.
