RESUMEN
Myopia is the most frequent kind of refractive error and affects hundreds of millions of people. Growing evidence suggests that extended exposure to digital screens may exacerbate nearsightedness in children and young people. The purpose of this review is to compile data on the link between too much time in front of a screen and nearsightedness in young people so far. The principles of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guided the methods used and the format of the resulting report. Articles published between January 1, 2000, and June 30, 2023, were found by searching Medline, PubMed, ScienceDirect, Google Scholar, CINAHL, the Cochrane Library, and Scopus. Studies reporting an association between myopia and time spent in front of screens in children and young adults were considered eligible. The initial search yielded a total of 1,251 studies. After eliminating duplicates and reviewing the titles and abstracts, 64 full-text articles were evaluated for eligibility. Ultimately, 15 of these studies were included in the final analysis. The 15 studies involved a total of 59,775 participants and were conducted in various countries, including China, Singapore, and the United States. Overall, the evidence did not support a significant association between screen time and myopia in school children and young adults. There is conflicting evidence on the link between screen time and myopia in children and adolescents. More research is needed to determine whether or not digital screen use is a risk factor for myopia. The complex association between screen time and myopia is not fully understood at this time because of the variability of the included studies. These results have significant public health implications since they may be used to guide recommendations for screen time use in children and the young population.
RESUMEN
Introduction: This study aimed to evaluate the awareness, knowledge, and attitude on diabetic retinopathy of final-year medical students and the association of knowledge, attitude, and practice with the gender of medical students. Methods: A descriptive cross-sectional study was conducted at the College of Medicine, Imam Mohammad Ibn Saud Islamic University (IMSIU), Riyadh, Saudi Arabia. The initial part of the questionnaire included demographic details, while the remaining parts of the questionnaire included six questions on knowledge, four on attitude, and three on practice. IBM SPSS Statistics 24 was used to retrieve and analyze data from an Excel file. A P value <0.05 was considered as statistically significant. Results: Of 84 medical students, 51 (60.71%) and 33 (39.19%) were male and female medical students, respectively. The total knowledge score for male and female medical students was 4.28 (SD = 0.92). The majority of students correctly answered practice questions, indicating good significant practice toward diabetic retinopathy among diabetic patients with A score of 1.93 (SD = 0.83). Conclusion: The majority of final-year medical students were good in knowledge and practice toward prevention and treatment of diabetic retinopathy, which helps them become better future care providers for patients with diabetes and diabetic retinopathy.
RESUMEN
We report a 39-year-old with Alport's syndrome. The patient presented with anterior lenticonus, cataract, and a corrected distance visual acuity of 20/25 and 20/60 in the right and left eyes, respectively. Fundus examination revealed generalized retinal flecks sparing the fovea in both eyes. Optical coherence topography showed temporal macular thinning. Normal fundus autofluorescence was observed in both eyes. Full-field electroretinography (ERG) demonstrated normal photopic and scotopic responses, while multifocal ERG showed no reduction of amplitudes generated from the temporal thinned macula, compared to the nasal macula, indicating preserved functional integrity of the retina.
