Data on clinical files (CL type, wearing time, visual acuity, symptoms, and clinical signs) of CL wearers who attended a Spanish eye setting between 2010 and 2020 were collected. The profile of CL wearers was compared between 2010 and 2020. The CL characteristics were compared between CL types, replacements, and designs. Finally, factors predicting a change in CL fitting were assessed. Seventy-four CL wearers (28 men and 46 women) aged 39.0 ± 9.1 years old were included. Silicone hydrogel (p = 0.01) and daily disposable (p < 0.001) CL fittings increased during the follow-up period. The main reasons for CL refitting were the appearance or increase of clinical signs and/or symptoms. CL wearing time and visual acuity differed between CL types and replacements (p ≤ 0.02). Both, rigid and conventional replacement CL wear were associated with a lower probability of CL fitting changes (p ≤ 0.03). In conclusion, this study provides useful clinical information about the profile of successful long-term CL wearers in the last decade. Adequate aftercare examinations of long-term CL wearers can avoid worsening of signs and symptoms. Hydrogel and frequent replacement CL wearers are more likely to undergo CL refitting when compared to rigid corneal and conventional CL wearers.","PeriodicalId":505407,"journal":{"name":"Ciencia y Tecnología para la Salud Visual y Ocular","volume":"34 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140966466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Estudiar y describir la relación entre la oclusión de la vena central de la retina y el glaucoma neovascular, su etiología, epidemiología, fisiopatología, factores de riesgo, presentación clínica y tratamientos. Metodología. Revisión de la literatura acerca del glaucoma neovascular secundario a oclusión de la vena central de la retina, tomando artículos comprendidos entre 2014 y 2022, con criterios de exclusión artículos de series de casos. Resultados. El glaucoma neovascular (GNV) es una afectación patológica ocular, secundaria a una afección ocular y/o sistémica hipóxica que conduce a isquemia retiniana, dentro de las etiologías más comunes (33 %) se encuentra la oclusión de la vena central de la retina (OVCR) una retinopatía vascular común que puede presentarse como isquémica o no isquémica. Discusión de resultados. La OVCR ocurre secundariamente a cambios estructurales glaucomatosos o coexiste con la anormalidad hemodinámica de la retina, esta es mediada por procesos inflamatorios como consecuencia de la isquemia retiniana y la hemorragia, lo cual aumenta la expresión de factor de crecimiento endotelial vascular (VEGF) y otros factores inflamatorios en el ojo, que pueden llevar a GNV. Conclusiones. El GNV es una patología con una presentación clínica severa, se asocia de forma directa con la OVCR y tiene múltiples opciones de tratamientos.","PeriodicalId":505407,"journal":{"name":"Ciencia y Tecnología para la Salud Visual y Ocular","volume":"148 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139182663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existe una información limitada sobre el impacto de la pandemia en la realización de cirugías y la razón que obedece a dicho aumento. Objetivo: identificar el efecto de la pandemia por covid-19 en la cirugía refractiva mediante la delimitación de las principales motivaciones para la realización del procedimiento. Métodos: estudio descriptivo observacional de corte transversal, por medio de la respuesta de un cuestionario sobre aspectos sociodemográficos y motivación quirúrgica. Resultados: fueron encuestados 203 participantes entre 31 y 40 años (47,8 %, n = 97), 18 y 30 años (39,9 %, n = 81) y mayores de 40 años (12,3 %, n = 25). El 61,1 % (n = 124) fueron mujeres y solo 3 (1,5 %) residían fuera de Colombia. Participaron con mayor frecuencia personas de estrato 4 (45,5 %) y 5 (24,3 %). Las principales motivaciones fueron: considerar que era el mejor momento para la cirugía, el deseo de evitar el uso de corrección óptica como respuesta al aumento del uso de pantallas y, por último, uso del tapabocas. Conclusiones: se demostró que el uso de tapabocas durante la pandemia, y el efecto de empañar las gafas, no fue una de las motivaciones más importantes, como sí lo fue el teletrabajo, pues la flexibilidad del horario laboral facilitó la posibilidad de la realización de cirugía refractiva, dejando este motivo como una de las posibles razones por las cuales se incrementaron los procedimientos realizados durante el 2020.","PeriodicalId":505407,"journal":{"name":"Ciencia y Tecnología para la Salud Visual y Ocular","volume":"99 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139182109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objetivo General: Determinar la prevalencia de astenopia reportada por la literatura en niños escolares de 6 a 17 años, por el uso de pantallas digitales durante la pandemia por COVID-19. Método de Investigación: Se realizo una revisión sistemática cualitativa mediante la pregunta PECO; la búsqueda bibliográfica de realizo en bases las bases de datos, con ecuaciones construidas con palabras clave a partir de DeCS y MesH, términos libres en inglés y español y operadores booleanos, se incluyeron artículos publicados entre 2020 y 2022. La calidad metodológica, se evaluó mediante herramientas como Newcastle-Ottawa y AMSTAR, se incluyeron artículos de revisión, estudios de casos y controles, y/o estudios transversales, que abordaran el tema prevalencia de astenopia por uso de los dispositivos electrónicos en escolares, durante la pandemia del COVID-19. El reporte de la revisión se realizó con base en la declaración PRISMA. Resultados: La prevalencia de astenopia reportada por los estudios revisados osciló entre 49,28% a 69,84%.en la población escolar durante la pandemia COVID-19, los síntomas más comunes fueron; ojo seco, cefalea, ardor y escozor ocular; El tiempo dedicado al uso de estos dispositivos aumento y, por otra parte, se asociaron a estos factores ergonómicos. Conclusiones: Esta revisión sistemática muestra que la prevalencia de astenopia se incrementó en todo el mundo. Las causas identificadas para el desarrollo de esta fatiga visual digital incluyen la demanda visual, la proximidad de trabajo, la iluminación, el tiempo de uso prolongado pantallas digitales, la disminución en la frecuencia de parpadeo y el uso de pantallas pequeñas, provocando la inestabilidad de la película lagrimal, aumento en defectos refractivos como la miopía y problemas acomodativos en los niños.","PeriodicalId":505407,"journal":{"name":"Ciencia y Tecnología para la Salud Visual y Ocular","volume":"117 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139182062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
