Abstract

Color vision deficiency is the inability of the eye to distinguish colors, this can occur both congenitally and acquired. Color vision deficiency can affect a person's quality of life performance and the selection of advanced study programs in children. This study aims to determine the prevalence and characteristics of color vision deficiency in detail in elementary school-age children. This study used a total sampling technique with a cross sectional method with 366 respondents. Data collection was carried out from September to October. In this study, 5.2% (10 people) of respondents experienced color vision deficiency. As many as 2.2% (8 people) of respondents had partial color vision deficiency and 0.5% (2 people) of respondents had color blindness (monochromat). Of the 195 male respondents, 4.6% of them suffered from color vision deficiency while of the 171 female respondents, 0.6% of them suffered from color vision deficiency. Color vision is related to cone cell photoreceptors. Each type of cone cell plays a role in color vision. The prevalence of students with color vision deficiency is 2.7%. In this study it was found that students had partial and total color vision deficiency (monochromat). The most common type of red-green color vision deficiency. The highest prevalence is in male students. It is recommended to the government and schools to carry out a complete eye examination including a color vision examination so that it can support the learning process and the selection of advanced study programs according to the child's condition.
Indonesia Correlation of Degree of Asthenopia in Corrected and Uncorrected Refractive Errors of 2020 Faculty of Medicine and Health Sciences Students: Korelasi Derajat Astenopia pada Kelainan Refraksi Terkoreksi dan Tidak Terkoreksi Mahasiswa Fakultas Kedokteran dan Ilmu Kesehatan Ilahi, Luthfiyana; Wihardjo, Erning; Goenawan, Kristian

Abstract

Asthenopia, or what is usually called tired eyes, is the occurrence of tension in the ciliary muscles in the eyes caused by intensive visual activity. The symptoms of asthenopia that are felt are subjective visual discomfort, which causes decreased concentration, academic performance, and work ability. This study aims to determine the correlation between the degree of asthenopia in corrected and uncorrected refractive errors in FKIK Ukrida students in the class of 2020. This study used a total sampling technique with a cross-sectional method with 159 respondents. Data collection was carried out in December. In this study, the number of respondents who had corrected refractive errors consisted of 30 (21.3%) people who did not experience asthenopia, 56 (39.7%) experienced mild asthenopia, 15 (10.6%) people experienced moderate asthenopia, and 1 (0.7%) experienced severe asthenopia. Respondents who had uncorrected refractive errors consisted of 10 (7.1%) people who did not have asthenopia, 13 (9.2%) had mild asthenopia, 14 (9.9%) people, and 2 people did not have severe asthenopia. The degree of asthenopia and the corrected refractive error are correlated, according to the Spearman test findings, with a p-value of 0.032. Symptoms of asthenopia can cause a decrease in visual quality and work ability. The results of this research found that FKIK students experienced more corrected refractive errors. Symptoms of asthenopia are many. Asthenopia is often found in corrected refractive errors. So, education is needed to prevent asthenopia in FKIK students.

Abstract

Refractive errors are the leading cause of visual impairment among school-aged children. Early detection is essential, particularly in children who have difficulty providing subjective responses. Objective refraction instruments, such as autorefractors and non-cycloplegic retinoscopes, can be used as alternatives. This study aimed to compare the objective refraction results obtained using an autorefractor and a non-cycloplegic retinoscope, and to determine which instrument provides results most closely aligned with subjective refraction. This cross-sectional study involved 196 students aged 7 to 12 years from SDN 17 Kebon Jeruk. Each participant underwent refractive examinations using all three methods. The spherical equivalent (SE) results were compared within a tolerance of ±0.25 diopters (D) and analyzed using the McNemar test. The findings showed that the non-cycloplegic retinoscope produced results significantly closer to subjective refraction (p < 0.001), with agreement rates of 83.7% in the right eye and 87.2% in the left eye. In comparison, the autorefractor showed agreement rates of 55.6% and 62.8%, respectively. The SE differences with the retinoscope were also smaller and more consistent. In conclusion, the non-cycloplegic retinoscope provides refractive values that are more comparable to subjective results than the autorefractor, making it a more recommended instrument for refractive screening in elementary school children.

Abstract

The main causes of N.VI paralysis in adults are microvascular disease, vasculopathy, tumors, and inflammatory conditions. However, recent studies suggest that neurotropic viruses may be the etiology of N.VI paralysis. COVID-19 also has neurotropic and neuroinvasive capabilities that make the eye susceptible to bilateral optic neuritis, papilledema, and cranial nerve paralysis, the most common of which is abducens nerve palsy. The aim of this literature review is to review studies that describe the occurrence of abducens nerve palsy in COVID-19 patients. The literature search began in the period April-May 2022 from the Google Scholar database (https://scholar.google.com/). This mini review used the AMSTAR (Assessment of Multiple Systemic Review 2, including randomized and nonrandomized studies) checklist and reviewers independently agreed on the selection of eligible studies and reached consensus regarding which studies to include with inclusion criteria. This mini review found that 75% of cases were strongly associated with viral infection and 25% of cases were strongly associated with COVID-19 vaccination. Only 50% of cases report improvement in abducens nerve palsy. This has the implication that with the increasing prevalence of COVID-19 worldwide, ophthalmologists should be aware that abducens nerve palsy may be part of COVID-19.
