    Lower tear meniscus height measured by optical coherence tomography in children

    Introduction: While optical coherence tomography (OCT) measurements of the lower tear meniscus height (LTMH) have been reported in adults, here we obtained LTMH measurements through Fourier Domain OCT in healthy children and compared these with values obtained in healthy adults. Methods: Participants were children 7–17 years of age and a control group of adults 20–40 years of age. Inclusion criteria were no abnormal eye conditions or the use of contact lenses. Candidates who fulfilled the TFOS DEWS II criteria for dry eye disease (DED) were excluded. All subjects underwent LTMH measurement (OCT Spectralis) and tests for non-invasive tear break-up time and ocular surface staining. Participants also completed the ocular surface disease index questionnaire. Results: A total of 86 children and 27 adults were included. Mean LTMH values in the children and adult groups were 217.40 ± 71.40 μm and 225.0 ± 54.86 μm, respectively; p = 0.53. However, 59.3% of the children had an LTMH ≤210 μm suggestive of DED, compared with only 33.3% of adults (p = 0.02). For the children, no significant differences in LTMH were observed with sex or for those more or less than 12 years of age. Conclusions: Optical coherence tomography-derived LTMH measurements were obtained in healthy children. While values were similar in children and adults, a greater proportion of children had an LTMH compatible with a diagnosis of DED. More studies in different paediatric populations are required to establish a complete set of normative LTMH measurements.

    Aprendizaje de procedimientos clínicos optométricos mediante vídeos demostrativos
    (2021) Piedrahita Alonso, María Elena; Martín García, Beatriz; Palomo Álvarez, Catalina; Nieto Bona, Amelia; Estrella Lumeras, Miguel Ángel; Barrio De Santos, Ana Rosa; Valcayo Peñalva, Isabel; Baños Morales, Carmelo
    El objetivo principal del proyecto ha sido crear en el campus virtual de la asignatura Optometría IV del Grado de Óptica y Optometría una plataforma de material docente virtual basado en presentaciones, vídeos de exploración y cuestionarios autoevaluativos. En ellos el alumno ha podido visualizar la ejecución por parte del profesor de los procedimientos que se estudian en la asignatura en pacientes pediátricos o con alteraciones de la visión binocular, de manera que el aprendizaje ha sido significativo.

    Complemento audiovisual para el aprendizaje de procedimientos clínicos optométricos de visión binocular no estrábica
    (2022) Piedrahita Alonso, María Elena; Antona Peñalba, Beatriz; Barrio De Santos, Ana Rosa; Martín García, Beatriz
    El resultado de este proyecto consta de 35 vídeotutoriales de exploración a pacientes, que complementan el aprendizaje de procedimientos clínicos relacionados con la visión binocular no estrábica. Sirven como guía previa a la realización de las prácticas y de complemento para el estudio de los procedimientos.
