El computer vision syndrome, CVSit is a condition that involves ocular problems, due to the time spent in front of a screen or device, generating significant effects such as insomnia, Migraineen respuesta al estres as a trigger and a central mediating factor, according to the suggestion of a new investigation.

The researchers administered an online questionnaire to more than 700 adults, of whom 71% had sex CVS.

Los resultados mostraron que la presencia de CVS y un major estres se asociaron significante con majores probabilitas de desarrollar estas condiciones.

“Este estudio ayudaría a los medicos en ejercicio a prevenir el computer vision syndrome advise patients on the importance of taking breaks when using a computer,” said principal investigator Souheil Hallit, PharmD, MSc, MPH, associate professor at the Holy Spirit Faculty of Medicine and Medical Sciences. Universidad de Kaslik, Jounieh, Lebanon.

“You can also take other preventive measures, such as adjusting the brightness of the screen to the lighting of the room, using screen filters and practicing good ergonomics,” said Hallit, who is also the director of the Cruz Psychiatric Hospital in Beirut.

¿Es esto acaso un problema de salud pública?

“Las computadoras y las pantalla de visualization se han convertido en una parte integral de nuestras rutinas diarias”, writen los researchers. Sin embargo, el augmento del tiempo frente a la pantalla “puede provocare trastornos de salud civos, especially problemas oculares”, conocidos como CVSaggregate.

Sumando a esto el incremento en horas de uso, gracias al home office o trabajo desde casa, gracias a la pandemia, se puede estar creando un “importante problema de salud pública”, señalan.

Symptoms que pueden desarrollar, a major uso de dispositivos o pantallas:

  • Picazon.

  • Vision borrosa o doble.

  • Dolor de ojos.

  • Dolor de cabeza.

  • Dolor de espalda, cuello y hombros.

  • Numbness of hands or fingers.

In addition, the blue light emitted by computer screens can interfere with the normal circadian rhythm, which causes digital visual fatigue. insomniaseñalan los inquisitors.

Stress is another trigger of attacks Migraine y también es un factor de riesgo para el desarrollo de Migraine crónica a partir de la Migraine episódica, episódica. Además, los eventos stressantes de la vida pueden induce el insomnia.

“We chose to realize this study because the use of the computer has become essential for our daily life. In addition, the prevalence of CVS está auamento en otras poblaciones y no hay estudios libaneses disponibles al respecto”, said Hallit.

“We also think that shedding light on the existence of this syndrome would help implement preventive measures to minimize the high prevalence of CVS entre los usuarios de computadoras”, he added.

The researchers administered an online questionnaire to all users of digital devices in all districts of Lebanon, and data collection took place during the government-imposed COVID-19 lockdown.

The 749 study participants (median age, 24 years; 65.6% women) were recruited through a snowball sampling technique, in which links were sent to individuals via WhatsApp and email. In addition, the participants were asked to send the link to other people who use digital devices.

Síntoma más perturbador

The results showed that 70.5% of the participants had them CVS. La cephalea was reported as “el síntoma ocular más preoccupante” (34 %), followed by escorzor en los ojos (10.8 %). The most troublesome extraocular symptoms were cervicalgia and lumbar pain (43.3% and 33.4%, respectively).

Un análisis multivariable utilizando un modelo de regresión lineal, y tomando la puntuación de insomnia como variable dependent, mostró que la presencia de CVS (ß = 3.26) se asoció significant con una major tasa de insomnia.

The researchers also analyzed the factors associated with it Migraine y encontraron que un percentage significande major de participants con Migraine eran mujeres que hombres (51.3 % frente a 41.5 %, respectively; P = 0.01) y tenien CVS frente a ningún CVS (53.8 % vs. 35.7 %, p = 0.001).

En particular, aquellos con Migraine they had a higher average stress score than those with a lower stress score (13.90 versus 9.92, respectively; P < 0.001).

CVS y major estres se asociaron significante con majores probabilidades de tener Migrainecomo se muestra en la siguiente tabla:

Un análisis de mediation showed que el stress mediaba la asociación entre CVS y Migraine en un 52.8 %, y entre CVS e insomnia at least 80%.

Hallit anotó que el studio “podría ayudar a los medicos” a controlar el insomnia.

“Al centrarse en el hecho de que use la computadora just antes de acostarse, sobre todo cuando se experiencia eventos stressantes de la vida, se asociación con el insomnialos médicos pueden tratar el insomnia sin necesidad de medicamentos”, he said.

“Además, encontrar que el dolor de cabeza por la pantalla es el síntoma más perturbadorador del CVS ayudaría a los médicos a tratar el dolor cabeza de forma non pharmacológica con ciertas preventive medidas, como usar un filtro de luz azul al usar una screenta computadora”, added Hallit.

Riesgo modifiable

La Dra. Alison Thaler, assistant professor of neurology at the Icahn School of Medicine in Mount Sinai, New York City, and member of the editorial board of the American Migraine Foundation, pointed out that stress is an “important risk factor for the Migraine“.

It can also “lead to a bad posture while working in front of a computer, which, with time, can activate trigger points in the muscles of the neck and shoulders that can trigger the Migraine“, said Thaler, who did not participate in the investigation.

Por esa razón, “tiene sentido que los niveles más altos de estres puedan fortarer la connexion entre el CVS y la Migraine. Cuanto peor es el estres, más probable es que el CVS se vincule con la Migraine“, he said.

“We can limit screen time when possible, avoid screen time before going to bed, and use blue light filter glasses to help prevent CVS provoque ataques de Migraine“, he said.
