ABSTRACT
AIM:To investigate the effect of vision therapy system 4D combined with stereoscopic 3D technology training for the treatment of amblyopia.METHODS: Prospective study. A total of 102 children with amblyopia who attended the clinic from January 2018 to January 2022 were selected, and they were randomly assigned into two groups by computer, with 51 cases in each group. Control group received stereoscopic 3D technology training, while observation group participated in vision therapy system 4D on the basis of control group. Then the overall effective rate, binocular visual function, spherical equivalent(SE), axial length(AL), mean corneal curvature(Km), best corrected visual acuity(BCVA)and visual evoked potential were compared between two groups.RESULTS: The overall efficacy rate was 94.1% in observation group, which was obviously higher than control group(74.5%; P<0.05). The improvement in binocular vision parameters simultaneous perception, total fusion, and stereoacuity were all more remarkable in observation group than in control group(P<0.05). The △SE, △AL and △Km yielded no statistical difference between two groups(P>0.05). The latency of two spatial frequencies(1°grid and 15'grid)showed a decline in both groups, and the decline was more notable in observation group than in control group(P<0.05). In both groups, BCVA improved, and the improvement was more significant in observation group compared with control group(P<0.05).CONCLUSION: Application of vision therapy system 4D combined with stereoscopic 3D technology training for amblyopia can effectively ameliorate the visual acuity, promote the reconstruction of simultaneous perception, total fusion, and stereoacuity without additional risk of myopic shift, and improve visual pathway function in children.
ABSTRACT
@#AIM:To evaluate the effect of stereoscopic 3D/4D technology as a visual training system combined with refractive correction and masking therapy for adult amblyopia.<p>METHODS: A retrospective study. From July 2018 to October 2020, totally 41 cases(57 eyes)adult amblyopia in our hospital were divided into severe, moderate, mild group, effect of stereoscopic 3D/4D technology training were analyzed after 6mo, including the best corrected visual acuity, visual evoked potentials, stereoscopic function.<p>RESULTS: After treatment, best corrected visual acuity of the patients were significantly improved, the effective rate of severe, moderate, mild amblyopia group were 69%, 88%, 75%, the total effective rate was 79%. The stereoscopic function of the patients were significantly improved, the effective rate of severe, moderate, mild amblyopia group were 62%, 75%, 80%, the total effective rate was 74%. The P100 wave latency periods of the visual evoked potentials were shortened after 6mo treatment, and the P100 wave amplitudes were increased(<i>P</i><0.05). <p>CONCLUSION:Stereoscopic 3D/4D technology training combined with refractive correction and masking therapy can effectively treat the adult amblyopic.
ABSTRACT
El proceso de capacitación en tecnología biomédica se enmarca dentro de los requerimientos del decreto # 4725 de 2005 emitido por el ministerio de protección social, y es parte del proceso de adquisición de tecnología el cual es de gran importancia para las instituciones prestadoras de salud en Colombia. La tecnología médica requiere procesos detallados de capacitación. Uno de los aspectos más importantes a considerar más no el único es la clasificación de riesgo de los dispositivos médicos, el cual es un factor muy importante porque puede cambiar el tiempo y costo de la capacitación. Este artículo pretende hacer una revisión de algunos modelos de capacitación en clínicas y hospitales y comprarlos entre sí, Adicionalmente el artículo presenta un modelo que se basa en los criterios más representativos de los modelos analizados.
The training in biomedical technology is part of the requirements of the decree # 4725 of 2005 issued by the Colombian Ministry of Social Protection, and it's part of the technology procurement process which is of great importance to the health institutions in Colombia. Medical technology requires detailed training processes. One of the most important aspects to consider, not the only one, is risk classification of medical devices, which is a very important factor that may affect time and cost of training. This article aims to review and compare some models of training in clinics and hospitals. In addition, the paper introduces a model based on the most representative criteria of the models analyzed.
