Síndrome visual informático en pacientes menores de 35 años

Introducción: El síndrome visual informático o fatiga visual digital es una enfermedad causada por el cansancio ocular que provoca el pasar mucho tiempo frente a una pantalla. Objetivo: Diagnosticar el síndrome visual informático en pacientes menores de 35 años atendidos en la consulta de refracción. Métodos: Se realizó un estudio descriptivo prospectivo y transversal de pacientes atendidos en la consulta de refracción del Policlínico Especialidades del Hospital Provincial Docente Clínicoquirúrgico Saturnino Lora, durante el periodo de abril a junio de 2022. Resultados: Predominaron los pacientes en las edades comprendidas entre 26 y 35 años y del sexo femenino; los síntomas más frecuentes fueron el cansancio visual, ardor ocular, sensación de ojo seco, visión borrosa de cerca, ojo rojo y el dolor de cabeza después del esfuerzo visual. Los dispositivos digitales más usados fueron el celular y la computadora con un tiempo de uso de una a tres horas, destacándose este último con un tiempo superior a 4 horas. Los defectos refractivos constituyeron la principal causa de limitaciones visuales. Los pacientes con síndrome visual informático y alguna ametropía sin corrección fueron los que mayor cantidad de síntomas tuvieron, seguidos de los pacientes corregidos inadecuadamente. Conclusiones: Este síndrome afecta en gran medida a la población más joven. El adecuado interrogatorio y la incorporación de los procedimientos correctos en el estudio optométrico diario permitió el diagnóstico de tal síndrome en los pacientes atendidos y la corrección óptica pertinente.

Introduction: Digital visual syndrome or digital visual fatigue is a disease caused by the ocular fatigue provoked by spending much time in front of a screen. Objective: To diagnose the digital visual syndrome in patients under 35 years assisted in the refraction service. Methods: A prospective descriptive and cross-sectional study of patients assisted in the refraction service of the Specialties Polyclinic in Saturnino Lora Teaching Clinical Surgical Provincial Hospital, was carried out from April to June, 2022. Results: There was a prevalence of patients aged 26 and 35 and female sex; the most frequent symptoms were visual fatigue, ocular burning, dry eye sensation, closely blurred vision, red eye and headache after visual effort. The most used digital devices were the cellphone and the computer with a time of use from one to three hours, with emphasis in the last one with more than 4 hours. The refractive defects constituted the main cause of visual limitations. The patients with digital visual syndrome and some type of ametropia without correction were those with more symptoms, followed by the patients inadequately corrected. Conclusions: This syndrome affects the youngest population to a great extent. The appropriate interrogation and the incorporation of correct procedures in the daily optometric study allowed the diagnosis of such a syndrome in the assisted patients and the pertinent optic correction.

Paracentral acute middle maculopathy in the immediate postoperative of cataract surgery / Maculopatia média aguda paracentral no pós-operatório imediato de cirurgia de catarata

ABSTRACT This case report identified paracentral acute middle maculopathy as the cause of severe and irreversible vision loss after cataract surgery. Cataract surgeons should be aware of known risk factors for the development of paracentral acute middle maculopathy. In those patients, extra care regarding anesthesia, intraocular pressure, and some other aspects of cataract surgery must be taken. Paracentral acute middle maculopathy is currently understood as a clinical sign evident on spectral-domain optical coherence tomography, and it is probably evidence of deep ischemic insult to the retina. It should be a differential diagnosis in cases of marked low vision acuity associated with no fundus abnormalities in the immediate postoperative period, as demonstrated in the presented case.

RESUMO O presente relato de caso identificou a maculopatia média aguda paracentral como a causa de baixa de acuidade visual severa e irreversível após cirurgia de catarata. Existem fatores de risco bem estabelecidos para o desenvolvimento da maculopatia média aguda paracentral que devem ser conhecidos pelos cirurgiões de catarata. Nesse contexto cirúrgico, precauções extras no tocante a procedimentos anestésicos, pressão intraocular e alguns outros aspectos da cirurgia devem ser consideradas. A maculopatia média aguda paracentral é descrita como um sinal clínico observado no exame de tomografia de coerência óptica por domínio espectral e se trata, provavelmente, da evidência de um evento isquêmico no tecido vascular retiniano. Esse diagnóstico deve ser cogitado nos casos de perda de acuidade visual súbita no pós-operatório imediato associada com exame fundoscópico normal, como evidenciado no caso apresentado.

Multisensory effects of mask wearing on speech intelligibility and the benefit of multilingualism / Efeitos multissensoriais do uso de máscara na inteligibilidade da fala e o benefício do multilinguismo

ABSTRACT Purpose Due to the pandemic of the Covid-19 disease, it became common to wear masks on some public spaces. By covering mouth and nose, visual-related speech cues are greatly reduced, while the auditory signal is both distorted and attenuated. The present study aimed to analyze the multisensory effects of mask wearing on speech intelligibility and the differences in these effects between participants who spoke 1, 2 and 3 languages. Methods The study consisted of the presentation of sentences from the SPIN test to 40 participants. Participants were asked to report the perceived sentences. There were four conditions: auditory with mask; audiovisual with mask; auditory without mask; audiovisual without mask. Two sessions were conducted, one week apart, each with the same stimuli but with a different signal-to-noise ratio. Results Results demonstrated that the use of the mask decreased speech intelligibility, both due to a decrease in the quality of auditory stimuli and due to the loss of visual information. Signal-to-noise ratio largely affects speech intelligibility and higher ratios are needed in mask-wearing conditions to obtain any degree of intelligibility. Those who speak more than one language are less affected by mask wearing, as are younger listeners. Conclusion Wearing a facial mask reduces speech intelligibility, both due to visual and auditory factors. Older people and people who only speak one language are affected the most.

RESUMO Objetivo Devido à pandemia da doença Covid-19, o uso de máscaras em espaços públicos tornou-se comum. Ao cobrir a boca e o nariz, reduzem-se amplamente as pistas visuais associadas à fala, assim como se distorce e atenua o sinal auditivo. Este estudo teve como objetivo analisar os efeitos multissensoriais do uso da máscara na percepção da fala e a diferença entre participantes falantes de uma, duas ou três línguas. Método Este estudo consistiu na apresentação de frases do SPIN teste a 40 participantes. Os participantes tinham como tarefa reportar as frases percebidas em quatro condições: Auditiva com máscara, audiovisual com máscara, auditiva sem máscara, audiovisual sem máscara. Conduziram-se duas sessões, com uma semana de intervalo, cada uma com os mesmos estímulos mas com diferente relação sinal-ruído. Resultados Os resultados demonstraram que o uso de máscara reduz a inteligibilidade da fala, tanto devido à diminuição da qualidade do estímulo auditivo, como devido à perda de informação visual. A relação sinal-ruído afeta a inteligibilidade e com o uso de máscara são necessárias relações mais altas para obter qualquer identificação correta. Aqueles que falam mais do que uma língua, assim como os mais novos, são menos afetados na percepção de fala com uso de máscara. Conclusão O uso de máscara facial reduz a inteligibilidade da fala, tanto devido a fatores visuais como auditivos. Indivíduos monolíngues, assim como os mais velhos, são os mais afetados nesta tarefa.

Findings of ocular examinations in healthy full-term newborns / Achados de exame ocular realizado em recém-nascidos a termo saudáveis

ABSTRACT Purpose: To assess the anterior and posterior segments of full-term neonates over a 1.5-year period. Methods: The findings of full-term neonates who underwent ophthalmological examinations between June 2019 and December 2020 were analyzed, and the results were retrospectively recorded. Results: The study comprised 2972 neonates with a mean birth week of 38.7 ± 1.2 weeks and a mean birth weight of 3235 ± 464 g. The neonates were examined on an average of 49.3 ± 18.9 postnatal days. Of the examined neonates, 185 (6.2%) showed abnormal ophthalmological findings, the most prevalent of which were retinal hemorrhage in 2.3% (n=68) and white changes in the peripheral retina in 1.9% (n=55) of the neonates. Cases of optic disc pathologies (n=20), choroidal nevus (n=10), iris-choroidal coloboma (n=5), subconjunctival hemorrhage (n=6), non-specific retinal pigmentary change (n=4), congenital cataract (n=3), posterior synechia (n=3), iris nevus (n=3), corneal opacity (n=1), choroidal coloboma (n=1), iris coloboma (n=1), buphthalmos (n=1), anophthalmos (n=1), microphthalmia (n=1), lid hemangioma (n=1), and vitreous hemorrhage (n=1) collectively accounted for approximately 2% of all neonates. Pathologies that could potentially impair vision, which were detected by ophthalmological examination, accounted for 1.2% of all neonates (n=37). Conclusion: The most prevalent finding of the ophthalmological examinations of neonates in the present study was retinal hemorrhage. Ophthalmological examinations of neonates can help in identifying diseases that may affect their vision and are curable or may lead to amblyopia in the long term.

Conclusão: O achado mais prevalente de exames oculares de recém-nascidos neste estudo foi hemorragia da retina. Exames oftalmológicos em recém-nascidos podem ser úteis na identificação de doenças que podem impactar a visão deles, podendo ser curáveis ou levar à ambliopia no longo prazo.

Cross-cultural validation into Portuguese of a questionnaire to assess computer vision syndrome in workers exposed to digital devices / Validação intercultural em português de um questionário para avaliar a síndrome visual do computador em trabalhadores expostos a dispositivos digitais

ABSTRACT Purpose: As digital devices are increasingly used at work, valid and reliable tools are needed to assess their effect on visual health. This study aimed to translate, cross-culturally adapt, and validate the Computer Vision Syndrome Questionnaire (CVS-Q©) into Portuguese. Methods: A 5-phase process was followed: direct translation, synthesis of translation, back-translation, consolidation by an expert committee, and pretest. To run the pretest, a cross-sectional pilot study was conducted with 26 participants who completed the prefinal Portuguese version of the CVS-Q© and were asked about difficulties, comprehensibility, and suggestions to improve the questionnaire. To evaluate the reliability and validity of the Portuguese version of the CVS-Q©, a cross-sectional validation study was performed in a different sample (280 workers). Results: In the pretest, 96.2% had no difficulty in completing it, and 84.0% valued it as clear and understandable. CVS-Q© in Portuguese (Questionário da Síndrome Visual do Computador, CVS-Q PT©) was then obtained. Validation revealed the scale's good internal consistency (Cronbach's alpha=0.793), good temporal stability (intraclass correlation coefficient=0.847; 95% CI 0.764-0.902, kappa=0.839), adequate sensitivity and specificity (78.5% and 70.7%, respectively), good discriminant capacity (area under the curve=0.832; 95% CI 0.784-0.879), and adequate convergent validity with the ocular surface disease index (Spearman correlation coefficient=0.728, p<0.001). The factor analysis provided a single factor accounting for 37.7% of the explained common variance. A worker who scored ≥7 points would have computer vision syndrome. Conclusions: CVS-Q PT© can be considered an intuitive and easy-to-understand tool with good psychometric properties to measure computer vision syndrome in Portuguese workers exposed to digital devices. This questionnaire will assist in making decisions on preventive measures, interventions, and treatment and comparing exposed populations in different Portuguese-speaking countries.

RESUMO Objetivos: À medida que a utilização de equipamentos digitais no emprego aumenta, a avaliação do seu efeito na saúde visual necessita de ferramentas válidas e robustas. Este estudo teve como objetivo traduzir, adaptar culturalmente e validar para português o Questionário da Síndrome Visual do Computador (CVS-Q©). Métodos: O procedimento foi realizado em 5 fases: tradução direta, síntese da tradução, tradução inversa, consolidação por um painel de especialistas, e pré-teste. Para fazer o pré-teste foi realizado um estudo piloto transversal aplicado a uma amostra de 26 participantes que completaram a versão pré-final da versão portuguesa do CVS-Q©, questionando por dificuldades, compreensão e sugestões de melhoria do questionário. Para avaliar a confiança e validade da versão portuguesa do CVS-Q© foi realizado um estudo transversal de validação em uma amostra diferente (280 funcionários). Resultados: No préteste, 96.2% dos participantes não apresentaram dificuldades no preenchimento do questionário, enquanto 84.0% indicaram que era claro e compreensível. Obteve-se, então, o CVS-Q© em português (Questionário da Síndrome Visual do Computador, CVS-Q PT©). A sua validação revelou uma boa consistência interna da sua escala (Cronbach's alpha=0.793), boa estabilidade tem poral (coeficiente de correlação interclasse=0.847; 95% CI 0.764-0.902, kappa=0.839), sensibilidades e especificidades adequadas (78.5% e 70.7%, respetivamente), boa capacidade de discriminação (área abaixo da curva=0.832; 95% CI 0.784-0.879), e uma adequada validade da convergência com o índice de doença da superfície ocular (ocular surface disease index - OSDI; coeficiente de correlação de Spearman=0.728, p<0.001). A análise fatorial revelou um único fator responsável por explicar a variância comum em 37.7%. Um funcionário com uma pontuação ≥7 pontos sofria de síndrome visual do computador. Conclusão: O CVS-Q PT© pode ser considerada uma ferramenta intuitiva, de fácil interpretação e com boas pro priedades psicométricas para avaliar a síndrome visual do computador em funcionários portugueses expostos a ecrãs digitais. Este questionário facilitará as decisões sobre medidas preventivas, intervenções e tratamento, e a comparação entre as populações expostas em diferentes países de língua portuguesa.

Saccadic movements during an exploratory visual search task in patients with glaucomatous visual field loss

ABSTRACT Purpose: To evaluate the saccadic movements of patients with visual field loss due to primary open-angle glaucoma. Methods: Thirteen patients with good visual acuity (0.2 logMAR or better) (seven patients with primary open-angle glaucoma 65 ± 13 years) and six controls (51 ± 6 years) yielded a comprehensive ophthalmological examination, including Humphrey Visual Field tests (SITA-Standard 24-2), and performed a monocular, exploratory digital visual search task that quantifies the duration for finding the number "4" on a random array of digits distributed on the screen. After individual adjustments of the angle and distance positioning, the screen was spatially matched with the 24-2 visual field, and divided into five areas for analysis. During the task, saccades were simultaneously recorded in the same eye with a video-based eye tracker. Results: The patients with primary open-angle glaucoma showed a significantly higher number of saccades/screen (median ± interquartile range, 59.00 ± 29.00 vs. 32.50 ± 19.75 saccades (p=0.027) and visual search time per screen (38.50 ± 60.14 vs. 23.75 ± 8.90 seconds (p=0.035) than the controls did. Although the univariate analysis indicated a significant correlation with visual field mean deviation (coefficient=26.19 (p=0.02), only the visual search time/screen was significantly associated with the number of saccades/screen in the multivariate regression model (coefficient=0.55 (p<0.001). Overall, no significant correlation was observed between the sectorial number of saccades and the sensitivity of the five visual field areas. Conclusions: The patients with primary open-angle glaucoma show impaired search performance and showed a higher number of saccades needed to find stimuli when performing the exploratory visual task.

Association of diabetic retinopathy with anxiety and depression / 国际眼科杂志(Guoji Yanke Zazhi)

As society advances and living standards improve, there is a growing emphasis on the impact of mental health on illness and the interaction between them. Diabetes mellitus is one of the most common underlying diseases, and it is often accompanied by depression and anxiety. There are also many complications of diabetes, such as diabetic retinopathy(DR). DR is the leading cause of vision loss in diabetes. Vision loss inevitably increases anxiety and/or depression, which in turn may directly or indirectly affect the treatment or progression of patients with DR. This article reviews how to determine the anxiety and depression status of patients with DR, related assessment tools and methods, and their interaction with the treatment of DR. The interaction of anxiety-depressive states with DR treatment was also discussed. This review aims to raise awareness of the mental health of patients with DR, enhance doctor-patient communication and build doctor-patient trust, thus enhancing treatment adherence and clinical efficacy for individuals with DR and helping them to improve the quality of life.

AIM: To explore the prevalence and influencing factors of poor vision among 3 014 primary school students in Wucheng District, Jinhua City, in order to provide evidence for the intervention measures of poor vision.METHODS: Using a cross-sectional study, a self-designed questionnaire was done, including general conditions and influencing factors of vision. The international standard logarithmic visual acuity chart was used for visual acuity detection. The risk factors that were statistically significant among the single factor groups were used as independent variables for multivariate Logistic regression analysis.RESULTS: A total of 1 367 students with poor vision were detected, the detection rate was 45.36%, among which mild poor vision rare was 26.08%; moderate rate was 11.51%; and severe rate was 7.76%. Multivariate Logistic regression analysis showed that senior grades, parental myopia, daily insufficient sleep and outdoor activity, overuse of electronics or computers and no eye exercise were risk factors for poor vision.CONCLUSION: The rate of poor vision among the primary school students was severe, schools should take measures to improve and prevent students' poor vision by increasing outdoor activity time, correcting poor reading and writing posture, and reducing the time spent on electronic products.

Characteristics of retinal microcirculation after phacoemulsification and factors affecting visual acuity / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To investigate the changes of retinal microcirculation after phacoemulsification and the influencing factors of visual acuity.METHODS: Retrospective analysis. A total of 264 cataract patients(264 eyes)who underwent phacoemulsification in our hospital from January 2022 to December 2022 were selected as the study objects. Patients were divided into &#x0026;#x003C; 0.3 group(66 eyes)and ≥0.3 group(198 eyes)according to the recovery of best corrected visual acuity(BCVA)at 3 mo after surgery. The changes of retinal microcirculation indexes were compared before and after treatment. Logistic regression and LASSO regression models were used to screen the influencing factors of postoperative BCVA. A nomogram prediction model of postoperative BCVA was constructed and verified. A restricted cubic spline Logistic regression model was established to analyze the dose-response relationship between end-diastolic velocity(EDV), peak systolic velocity(PSV)and the risk of BCVA recovery.RESULTS: At 3 mo postoperatively, EDV and PSV were significantly improved compared with those before treatment, and resistance index(RI)levels were significantly lower than those before treatment(all P&#x0026;#x003C;0.05). Preoperative EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade were influencing factors for poor BCVA recovery after phacoemulsification in cataract patients(P&#x0026;#x003C;0.05). The AUC before and after validation of the nomogram model by Bootstrap method were 0.869(95%CI: 0.815-0.903)and 0.866(95%CI: 0.802-0.895), respectively. The sensitivity was 88.36% and 88.27%, and the specificity was 91.82% and 91.78%, respectively. Restricted cubic spline model analysis showed no nonlinear dose-response relationship between EDV and PSV levels and the risk of poor BCVA recovery in either male or female(P&#x0026;#x003E;0.05).CONCLUSION: After phacoemulsification, retinal microcirculation in cataract patients improved significantly. EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade are all factors influencing poor BCVA recovery after cataract surgery.

Comparison of short-term visual acuity and visual disturbance phenomena and spectacle independence after implantation of three different intraocular lenses / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the short-term postoperative visual acuity, visual disturbance phenomena, and spectacle independence rate in patients who underwent monocular implantation with trifocal, multifocal, or extended range of vision intraocular lens(IOL).METHODS: A retrospective analysis was conducted on 67 cataract patients(67 eyes)who underwent phacoemulsification cataract extraction combined with IOL implantation from March 2019 to December 2022. A total of 35 cases(35 eyes)received Symfony extended range of vision IOL implantation, 21 cases(21 eyes)received AcrySof IQ ReSTOR +3D multifocal IOL, and 11 cases(11 eyes)received AcrySof IQ PanOptix trifocal IOL. The preoperative uncorrected distance visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA), and uncorrected near visual acuity(UNVA)and 3 mo postoperatively were documented. Moreover, defocus curves, visual disturbance phenomena, and spectacle independence rates were recorded at 3 mo postoperatively.RESULTS: At 3 mo postoperatively, no statistically significant differences were observed in UDVA among the three groups(P&#x0026;#x003E;0.05). A comparison of UIVA showed superior results in the Symfony and PanOptix groups compared to the ReSTOR group(all P&#x0026;#x003C;0.01). The UNVA of both the ReSTOR and PanOptix groups outperformed the Symfony group(all P&#x0026;#x003C;0.01). The defocus curves indicated that in the intermediate vision range(-1.00 to -1.50 D), the Symfony group exhibited better performance than the ReSTOR group(P&#x0026;#x003C;0.05); while in the near vision range(-2.50 to -3.50 D), the ReSTOR group was superior to the Symfony group(P&#x0026;#x003C;0.05). The PanOptix group demonstrated superior visual acuity in the near vision range(-2.00 to -3.50 D)compared to the Symfony group(P&#x0026;#x003C;0.05)and was also superior in the intermediate vision range(-1.00 to -2.00 D)compared to the ReSTOR group(P&#x0026;#x003C;0.05). No significant differences were observed in the incidence of glare or halo and binocular interference phenomena among the three groups(P&#x0026;#x003E;0.05). The PanOptix and ReSTOR groups exhibited a higher spectacle independence rate compared to the Symfony group(P&#x0026;#x003C;0.0167).CONCLUSION: Compared to Symfony extended range of vision IOL and ReSTOR multifocal IOL, PanOptix trifocal IOL offers a balanced approach to distance, intermediate, and near visual acuity, without a high incidence of glare and halo, and with a higher spectacle independence rate. Caution is still advised when considering monocular implantation with presbyopia-correcting IOLs.

Transition from an in-person to a telemedicine diabetic retinopathy screening program

ABSTRACT Purpose: Timely screening and treatment are essential for preventing diabetic retinopathy blindness. Improving screening workflows can reduce waiting times for specialist evaluation and thus enhance patient outcomes. This study assessed different screening approaches in a Brazilian public healthcare setting. Methods: This retrospective study evaluated a telemedicine-based diabetic retinopathy screening implemented during the COVID-19 pandemic and compared it with in-person strategies. The evaluation was conducted from the perspective of a specialized referral center in an urban area of Central-West Brazil. In the telemedicine approach, a trained technician would capture retinal images by using a handheld camera. These images were sent to specialists for remote evaluation. Patient variables, including age, gender, duration of diabetes diagnosis, diabetes treatment, comorbidities, and waiting time, were analyzed and compared. Results: In total, 437 patients with diabetes mellitus were included in the study (mean age: 62.5 ± 11.0 years, female: 61.7%, mean diabetes duration: 15.3 ± 9.7 years, insulin users: 67.8%). In the in-person assessment group, the average waiting time between primary care referral and specialist evaluation was 292.3 ± 213.9 days, and the referral rate was 73.29%. In the telemedicine group, the average waiting time was 158.8 ± 192.4 days, and the referral rate was 29.38%. The telemedicine approach significantly reduced the waiting time (p<0.001) and significantly lowered the referral rate (p<0.001). Conclusion: The telemedicine approach significantly reduced the waiting time for specialist evaluation in a real-world setting. Employing portable retinal cameras may address the burden of diabetic retinopathy, especially in resource-limited settings.

Impairments and related social inequalities among adults: a population-based study in São Paulo city, Brazil / Deficiências e desigualdades sociais entre adultos: um estudo de base populacional na cidade de São Paulo, Brasil

Abstract The study of the association of social variables with the prevalence of impairments can provide subsidies for more adequate care and health policies for the most needy people by incorporating social aspects. This article aims to estimate the prevalence of diverse types of impairments, the degree of difficulty, limitations, and the need for help they cause and attest whether this prevalence differ by educational attainment in individuals aged 20 years or older. This is a populational cross-sectional study (2015 Health Survey of São Paulo-ISA Capital). Data from 3184 individuals were analyzed via educational attainment as exposure variable and outcome variables related to visual, hearing, intellectual, and mobility impairments. 19.9% of participants had visual, 7.8%, hearing, 2.7%, intellectual, and 7.4%, mobility impairments. Mobility and intellectual impairments limited participants' daily activities the most, 70.3% and 63.3%, respectively; who, thus, needed the most help: 48.9% and 48.5%, respectively. Lower schooling was associated with a higher prevalence of impairments, greater need for help due to visual and intellectual impairments, and greater limitations due to hearing and visual impairments.

Resumo O estudo da associação de variáveis ​​sociais com a prevalência de deficiências pode fornecer subsídios para uma atenção e políticas de saúde mais adequadas às pessoas mais carentes ao incorporar aspectos sociais. O objetivo deste artigo é estimar a prevalência de diversos tipos de deficiências, o grau de dificuldade, as limitações e a necessidade de ajuda e verificar se essa prevalência difere por escolaridade em indivíduos com 20 anos ou mais. Trata-se de um estudo transversal populacional (Inquérito de Saúde de São Paulo 2015 - ISA-Capital). Os dados de 3.184 indivíduos foram analisados ​​com a escolaridade como variável de exposição relacionada às deficiências visuais, auditivas, intelectuais e de mobilidade. Dezenove vírgula nove por cento dos participantes apresentavam deficiência visual, 7,8% auditiva, 2,7% intelectual e 7,4% de mobilidade. Mobilidade e deficiência intelectual foram as que mais limitaram as atividades diárias, 70,3% e 63,3%, respectivamente, sendo, portanto, as que mais necessitaram de ajuda: 48,9% e 48,5%, respectivamente. Menor nível de escolaridade mostrou associação com maior prevalência de deficiências, maior necessidade de ajuda por deficiência visual e intelectual e maiores limitações por deficiência auditiva e visual.

Introducción: El uso excesivo de las redes sociales ha generado diversas secuelas en la salud mental y visual-ocular, dando lugar al Síndrome Visual Informático (SVI) por sobreexposición a las pantallas. Objetivo: Analizar la influencia del uso de las redes sociales en el síndrome visual informático en adolescentes en una realidad peruana. Métodos: Se realizó una investigación de enfoque cuantitativo, hipotético-deductivo, transaccional, correlacional-causal, con una muestra de 126 adolescentes. Para recabar información acerca del uso de las redes sociales, se utilizó el ARS de Escurra y Salas. Para verificar la prevalencia del SVI, se empleó el Cuestionario de Síndrome Visual Informático de Seguí y colaboradores; ambos instrumentos fueron adaptados a formato Google Forms para su aplicación en línea. Resultados: Se encontró una asociación significativa entre el tiempo de permanencia en las redes sociales (RS) y el SVI (p=0,027<0,05); además, se evidenció el impacto significativo de la Adicción a las Redes Sociales (ARS) sobre el SVI (p=0,000<0.01), los síntomas visuales (p=0,000<0.01), oculares (p=0,000<0.01) y astenópicos (p=0,003<0.01). Conclusiones: El estudio demuestra una clara conexión entre el uso excesivo de redes sociales y el SVI en adolescentes peruanos, subrayando la necesidad de una acción conjunta de padres y educadores para mitigar los riesgos y promover un uso digital saludable.

Introduction: The excessive use of social media has generated various sequelae on mental and visual-ocular health, leading to Computer Vision Syndrome (CVS) due to screen overexposure. Objective: To analyze the influence of social media use on computer vision syndrome in adolescents in a Peruvian context. Methods: A quantitative, hypothetical-deductive, transactional, correlational-causal study was conducted with a sample of 126 adolescents. To gather information about social media use, the ARS by Escurra and Salas was used. To verify the prevalence of CVS, the Computer Vision Syndrome Questionnaire by Seguí and collaborators was employed; both instruments were adapted to Google Forms format for online application. Results: A significant association was found between the time spent on social media (SM) and CVS (p=0.027<0.05); additionally, a significant impact of Social Media Addiction (SMA) on CVS (p=0.000<0.01), visual symptoms (p=0.000<0.01), ocular symptoms (p=0.000<0.01), and asthenopic symptoms (p=0.003<0.01) was evidenced. Conclusions: The study demonstrates a clear connection between excessive use of social media and CVS in Peruvian adolescents, highlighting the need for joint action by parents and educators to mitigate risks and promote healthy digital use.

Síndrome de Balint y trombosis de senos venosos cerebrales: reporte de caso / Balint syndrome and cerebral venous sinus thrombosis: Case report

Introducción: El síndrome de Balint es un trastorno neurológico infrecuente, de etiología diversa, cuya presentación incluye la triada clásica de: simultagnosia, ataxia óptica y apraxia oculomotora, síntomas secundarios asociados a lesiones parieto-occipitales, con pronóstico variable según la etiología que se encuentre. A continuación, se reporta un caso secundario a una trombosis de senos venosos. Presentación del caso: Mujer de 66 años que ingresa a urgencias por cefalea aguda asociada a síntomas neurológicos progresivos con compromiso visual. Presentó tensión arterial elevada, simultagnosia, ataxia óptica y apraxia oculomotora. Los estudios imagenológicos reportaron hemorragia subaracnoidea por trombosis de seno sigmoideo izquierdo, por lo que se inició anticoagulación, antihipertensivo, con adecuada evolución del cuadro clínico. Discusión: A pesar de que el síndrome de Balint es un trastorno poco común, de etiología diversa, con escasos reportes a escala global, el caso comentado concordó con las características descritas en la literatura. El abordaje de la paciente en su atención inicial permitió la sospecha diagnóstica oportuna y la indicación de ayudas diagnósticas imagenológicas pertinentes. Tales ayudas soportaron un manejo temprano y la adecuada evolución y resolución del cuadro, en el contexto de la asociación del síndrome a una trombosis de senos venosos cerebrales (una etiología infrecuente). Conclusión: Mediante una historia clínica completa y minuciosa, junto a un adecuado examen neurológico, es posible hacer un acercamiento diagnóstico temprano que permita generar la sospecha del síndrome de Balint y la solicitud temprana de imágenes diagnósticas que orienten en el estudio de su etiología y manejo oportuno, con mejores desenlaces en el paciente.

Introduction: Balint Syndrome is a rare neurological disorder with multiple etiologies. The physical signs include a classic triad (simultagnosia, optic ataxia, and oculomotor apraxia). These symptoms are associated with parieto-occipital lesions, and the prognosis depends on the etiology. This article reports a case secondary to venous sinus thrombosis. Presentation of the case: A 66-year-old woman presented to the emergency room with acute headache associated with progressive neurological symptoms and visual impairment. She had high blood pressure, simultanagnosia, optic ataxia, and oculomotor apraxia. Imaging studies revealed subarachnoid hemorrhage due to thrombosis of the left sigmoid sinus, for which anticoagulation and antihypertensive therapy were started. The patient had a favorable clinical outcome. Discussion: Although Balint syndrome is a rare disorder of diverse etiology with few clinical cases reported globally, the case discussed here was consistent with the characteristics described in the literature. The patient's initial assessment allowed for timely diagnostic suspicion and appropriate imaging studies, which supported early management and the appropriate evolution and resolution of the condition, given the association of the syndrome with an uncommon cause as cerebral venous sinus thrombosis. Conclusion: A complete and thorough medical history, along with a proper neurological exam, can lead to an early diagnostic approach that raises suspicion of Balint's syndrome and prompts timely imaging studies to guide the investigation of its etiology and management, ultimately leading to better outcomes for the patient.

Accuracy of an artificial intelligence-based mobile application for detecting cataracts: Results from a field study

Purpose: To assess the accuracy of e?Paarvai, an artificial intelligence?based smartphone application (app) that detects and grades cataracts using images taken with a smartphone by comparing with slit lamp?based diagnoses by trained ophthalmologists. Methods: In this prospective diagnostic study conducted between January and April 2022 at a large tertiary?care eye hospital in South India, two screeners were trained to use the app. Patients aged >40 years and with a best?corrected visual acuity <20/40 were recruited for the study. The app is intended to determine whether the eye has immature cataract, mature cataract, posterior chamber intra?ocular lens, or no cataract. The diagnosis of the app was compared with that of trained ophthalmologists based on slit?lamp examinations, the gold standard, and a receiver operating characteristic (ROC) curve was estimated. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were computed. Results: The two screeners used the app to screen 2,619 eyes of 1,407 patients. In detecting cataracts, the app showed high sensitivity (96%) but low specificity (25%), an overall accuracy of 88%, a PPV of 92.3%, and an NPV of 57.8%. In terms of cataract grading, the accuracy of the app was high in detecting immature cataracts (1,875 eyes, 94.2%), but its accuracy was poor in detecting mature cataracts (73 eyes, 22%), posterior chamber intra?ocular lenses (55 eyes, 29.3%), and clear lenses (2 eyes, 2%). We found that the area under the curve in predicting ophthalmologists’ cataract diagnosis could potentially be improved beyond the app’s diagnosis based on using images only by incorporating information about patient sex and age (P < 0.0001) and best?corrected visual acuity (P < 0.0001). Conclusions: Although there is room for improvement, e?Paarvai app is a promising approach for diagnosing cataracts in difficult?to?reach populations. Integrating this with existing outreach programs can enhance the case detection rate.

A comparative study of vision-related quality of life (VRQoL) among glaucoma and nonglaucoma patients at a tertiary care center of North India

Purpose: Glaucoma influences vision?related quality of life (VRQoL) of an individual in various ways. There are very limited studies on the Indian population and the northern part of India. Therefore, we conducted the present study to evaluate VRQoL in glaucoma patients as well as the association between the severity of glaucoma and VRQoL. Methods: An institution?based, cross?sectional, analytical study was conducted from August 2022 to October 2022 involving 190 participants (95 glaucoma patients and 95 controls). The glaucoma quality of life?15 (GQL?15) questionnaire was explained in their vernacular language by the interviewer. The scoring was given according to the validated scoring algorithm for the questionnaire. Results: Mean GQL score in the control group was 19.66 ± 5.5 and in glaucoma cases was 32.8 ± 10.2, whereas the mean score of mild glaucoma cases was 22.3 ± 4.83, moderate glaucoma cases was 36.3 ± 4.09, and severe glaucoma cases was 47.24 ± 3.03. Therefore, as the severity of glaucoma increases, the GQL score also increases, indicating poorer quality of life. Visual field loss was strongly positively correlated (correlation coefficient = 0.759, P < 0.01) with the GQL?15 score, while a weaker positive correlation was found with best corrected visual acuity (BCVA), cup disc ratio, and duration of treatment. Conclusion: Besides controlling or reducing intraocular pressure (IOP) to the target level, the goal of glaucoma treatment should be to provide an individual with good functional vision to maintain an acceptable quality of life. It would also help in providing patients with the best possible treatment, not only in terms of good vision but also in maintaining or improving their overall quality of life.
