“…Similarmente, Iqbal et al, (2021) realizaron una investigación en estudiantes de una universidad de Egipto cuyo propósito fue evaluar exámenes visuales y establecer diversas afectaciones visuales, entre ellos el SVI de 623 estudiantes universitarios. Los resultados indicaron que el 87.9% de los estudiantes presentan quejas asociadas al SVI, siendo la prevalencia de este del 76%.…”

El objetivo de este artículo es analizar la literatura existente sobre la el SVI y sus afectaciones a las personas producto por alta exposición a equipos electrónicos generados por la pandemia del COVID-19 El tipo de investigación es revisión de literatura, de diseño bibliográfico o documental; el método de investigación empleado fue el de revisión de literatura. La población estuvo constituida por 35 artículos y la muestra de 19 artículos en diversos idiomas, seleccionados de manera intencional de acuerdo a criterios de inclusión y exclusión previamente establecidos; las técnicas e instrumentos empleados para el recojo de información fueron el análisis documental, y el fichaje y la computadora respectivamente. Entre los principales resultados se tiene que el SVI tiene gran prevalencia en personas que tienen gran periodo de exposición a pantallas de dispositivos electrónicos, asimismo, vinculados a fallas en las condiciones ergonómicas en sus estaciones de trabajo o estudio. Se concluye, el promedio de prevalencia del SVI en los artículos revisados es de 73.2%, siendo el máximo 98.7% y el mínimo 50%, siendo más frecuente en mujeres; respecto a los síntomas más frecuente que se presentan se tienen: dolor en ojos, cansancio visual o visión borrosa, picazón, sequedad en los ojos, sensación de empeoramiento de la vista, lagrimeo párpados pesados.

“…Furthermore, through their documented multifocal electroretinogram (mfERG) examinations, they also proved that CVS elicits screen-induced foveal dysfunction. ese visual sequelae might also cause simulated near vision troubles related to presbyopia [72]. e occurrence of digital eye strain is similar to presbyopic problems.…”

Background. Presbyopia is a primary cause of a decline in near vision. In this study, we developed a new mixed herbal medicine to retard presbyopic progression and increase the amplitude of accommodation (AA), which is beneficial for near vision. Methods. A total of 400 participants between the ages of 45 and 70 years were recruited. We designed the mixed herbal drug to include Cassiae Semen (200 mg), wolfberry (200 mg), and Dendrobium huoshanense (DD) (40 mg) in one capsule. In experiment 1, the recruited subjects were directed to perform a push-up test to measure their AA; this was then converted to the additional diopters of reading glasses. In experiment 2, 240 subjects took three capsules daily for six months and then stopped medical therapy for a six-month follow-up. In experiment 3, 160 subjects were randomly categorized into four groups: a placebo group, low-dose group (LDG) (1 capsule daily), middle-dose group (MDG) (two capsules daily), and high-dose group (HDG) (three capsules daily). The 160 volunteers took different doses for six months and then stopped treatment, accompanied by another six-month follow-up. In experiments 2 and 3, the change in AA, uncorrected far visual acuity (UFVA), and uncorrected near visual acuity (UNVA) were recorded each month for one year. Results. In experiment 1, AA was found to decrease with age and a great deal of additional power was needed in older individuals. In experiment 2, the mean AA reached a maximum value of 2.1D ( P < 0.05) after six months, while the UNVA improved by about two to three lines of a Jaeger chart in most of the subjects. At nine months, all the means decreased slightly to 2.0 D ( P < 0.05). This meant that the mixed herbal medicine could still maintain AA for another three months because the herbal therapy was stopped at the seventh month. In experiment 3, the maximal AA was 2.8D, 2.9D, and 3.2D ( P < 0.05) in the LDG, MDG, and HDG after six-month treatments, respectively. Experiment 3 showed that AA gain occurred in a dose-dependent manner; the higher the dose, the greater the AA value. Conclusion. Only two studies on the use of herbal drugs for presbyopia have been reported in PubMed. In our study, we found that taking a mixed herbal drug caused an excellent gain in AA. This is the first study to report that the characteristics of the new herbal regimen could retard and even ameliorate presbyopia.

“…Вторая позиция связана с актуальностью разработки методики оценки качества жизни (КЖ) пациентов с явлениями КЗС. В этой связи следует подчеркнуть, что к настоящему моменту применительно к исследованию КЖ у пациентов зрительно-напряженного труда апробированы лишь единичные методики, к числу которых, в частности, относится комплексная оценка выраженности астенопии, разработанная Экспертным советом по аккомодации и рефракции (ЭСАР) [13], отечественный опросник «КЗС» [18], а также зарубежные опросники «CVS-F3» [21] и «OSDI» [22]. Проведенный анализ показывает, что указанные методики не в полном объеме соответствуют современным стандартам исследования КЖ в клинической медицине, согласно которым разработка опросника основывается на много этапном процессе, целью которого является максимально точное и полное описание именно того состояния, которое является предметом оценки, с последующим статис тическим подтверждением достоверности, надежности и чувствительности созданного инструмента [23].…”

Purpose: to analyze the main subjective manifestations of computer vision syndrome (CVS).Materials and methods. We examined 100 patients aged 24–36, whose daily professional activity (at least for 2 years) involved visual-intensive work associated with electronic display systems (at least 4 hours a day) and requiring a sufficiently high responsibility level. All patients had complaints characteristic of asthenopia in CVS, indicating the stages of subcompensation or decompensation (in accordance with the recommendations of the Expert Council for Accommodation and Refraction of All-Russian Public Organization “Association of Ophthalmologists”). Each patient underwent an individual interview which was conducted according to the standard technique in order to identify the range of complaints that arise from long-term work with a computer.Results. The most common ocular (visual) subjective manifestations included the foreign body sensation, “sand” and itching in the eye; dry eyes; tiredness of vision; redness of the eyeballs; tension of eye muscles; “cramps”, burning in the eye — (which was mentioned by 100% of the testees). Other manifestations were somatic (headache — 89%; pain in the neck and the back — 79%), professional (patients wishing to interrupt work or take a break — 83%; periodic loss of visual concentration — 77%) and medico-psychological (the fear of vision deterioration — 65%).Conclusion. The established subjective manifestations improve the prospects of CVS diagnostics and can serve as basis for assessing the quality of life of patients engaged in vision intensive work.
