Myopic Shift

In this research, we represent the changes in visual acuity during pregnancy and after delivery. Changes as myopic shift start during second trimester and will be stopped after delivery; however it is obtained that women will have the same refractive error as what they had in the first trimester, after postpartum. So, any change in their spectacle prescription during this period is forbidden. As a result, not only changing in hormones can cause myopic shift in vision, but also overweight has its retributive role. What we are trying to do is to notify gynecologists and optometrists to be aware of these changes, so as to leave spectacle prescription writing to the session after postpartum period.

Uncorrected Refractive Error

Refractive disorders begin to affect many children and become a burden of disease in the community due to lack of awareness by parents and screening by health workers. This research was a cross-sectional study and carried out at screening of visual acuity in primary school-aged children. A total of 38 children aged 6 - 12 were the subjects in this study. This research was conducted in Banjararum sub-district, Kulon Progo Regency, Yogyakarta Special Province in September 2018. The average age of subjects was 8.8 ± 1.4 years. Result showed refraction status before correction (uncorrected refractive error/URE) with mean visual acuity of 0.3 logMAR (equivalent to 6/12 Snellen). The most common refractive disorders were myopia simplex (63.2%) and 38.8% of subjects experienced moderate visual impairment. After being corrected, as much as 97.4% of subjects reached normal vision. Burden of undiagnosed refractive disorders in rural population was high even though the visual disturbance is reversible.

Purpose To evaluate the efficacy and safety of the multifocal excimer laser corneal ablation profile (the Supracor procedure) in hyperopic presbyopia 1 year after laser treatment. Methods This prospective, consecutive, one-center, cross-sectional study included 20 patients with hyperopic presbyopia 1 year after treatment with the Supracor procedure. The main outcome measures were monocular uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA), photopic contrast sensitivity (Pelli-Robson charts), patient satisfaction, and functioning at 12 months. Results Thirty-nine eyes of 20 patients (mean age 59 ± 7.2 years) were treated. Mean UDVA improved from 0.56 ± 0.31 (mean 0.34 logMAR) preoperatively to 0.9 ± 0.15 (mean 0.06 logMAR) 12 months after surgery. Mean UNVA increased from 0.15 ± 0.07 (mean 0.84 logMAR) before surgery to 0.62 ± 0.24 (mean 0.23 logMAR) 12 months after treatment. Four eyes lost 2 lines of corrected distance visual acuity (10.3%). Monocular photopic contrast sensitivity was within age-correlated normal range (Pelli-Robson chart, mean contrast sensitivity 1.83 ± 0.18). A total of 75% of the patients would undergo Supracor again (1 not, 4 perhaps). The most frequently reported side effects were increased glare, reduced distance vision, and fluctuations in vision. Most patients used artificial tears. Conclusions One year after Supracor, UDVA and UNVA improved markedly, photopic contrast sensitivity was in normal age-correlated range, and the majority of patients (75%) was satisfied with the results. Side effects like loss of distance vision, fluctuations of vision, and increased glare have a greater influence on patient satisfaction than the improvement of spectacle-free near vision.

ObjectivesTo determine the prevalence, causes and associated factors for visual impairment (VI) in rural population of Jhajjar district, Haryana, north India.MethodsA community-based, cross-sectional study was conducted in two blocks of Jhajjar district. A total of 34 villages were selected using probability proportionate to size sampling method. Adults aged 50 years and above were selected using compact segment cluster sampling approach. Presenting visual acuity using LogMAR E chart was measured along with collection of other demographic details as part of the house-to-house survey. Subjective refraction and torch light examination were performed at a clinic site within the village to ascertain VI and its cause. VI was considered when presenting visual acuity was less than 6/18 in the better eye. Common causes of VI viz uncorrected refractive errors, cataract, central corneal opacity and others were noted by optometrists. Descriptive analysis was undertaken. Multivariate logistic regression analysis was performed for determining associated factors with VI.ResultsOut of 2025 enumerated adults, 1690 (83.5%) were examined at the household level and 1575 (78%) completed all study procedures. The prevalence of VI was found to be 24.5% (95% CI 21.1 to 26.3) and blindness was 5% (95% CI 3.9 to 6.1). The most common causes of VI were uncorrected refractive errors (50%) and cataract (37%). The VI in study participants was found to be associated with age, gender, marital and educational status.ConclusionsVI is still a public health problem in rural population of Jhajjar district, Haryana. Provision of spectacles and cataract surgical services are simple interventions to address this issue.

Aims: To determine the burden and factors associated with refractive errors after cataract surgery in a training institution. Study Design: A retrospective cross-sectional study. Place and Duration of the Study: Kilimanjaro Christian Medical Center Eye department. Northern Tanzania, from January 2016 to December 2017. Methods: A review of files of all adult patients who have had cataract surgery in 2016 and 2017 was conducted. A total of 626 eyes of 554 patients who had post-operative refraction by experienced optometrists were included. Information were extracted from patients’ files then entered into SPSS version 20 for analysis. The main outcomes were post-operative refraction and best corrected visual acuity.  Results: Mean age was 69.3 years (SD=10.7) and ECCE accounted for 76% of surgeries. At least 84.6% had post-operative refractive error and astigmatism was the most common refractive error (56.8%). Spherical error accounted for 27.8%. Spherical error ranged from -12 to 4DS, mean = -0.42 (SD=1.3) DS and median = 0.00DS. The maximum cylindrical error was -7.5 DC, mean = -1.15 (SD=1.36) DC and median = -1.0DC. At least 56% had spherical equivalent within 1D of emmetropia. A BCVA of 6/18 or better was achieved in 92.8%. Age, poor pre-operative VA, poor presenting VA, astigmatism on keratometry, difference between recommended and inserted IOL, ECCE, grade of surgeon and suturing were associated with refractive errors. Conclusion: Refractive errors following cataract surgery are common. Best corrected visual acuity outcome was in normal recommended range; however, the magnitude of refractive errors was high and the proportion of patients who achieved a final refraction within 1D of emmetropia was below the recommended range. An effort should be made to lower the prevalence and magnitude of refractive errors associated with cataract surgery in training institutions.

Children With Down Syndrome

BACKGROUND Down syndrome, first described in 1866, is the most common chromosomal derangement in live births. More than half of the patients with Down syndrome have ophthalmic manifestations. We wanted to evaluate the most common ocular abnormalities in children with Down syndrome in South India. METHODS All children with positive chromosomal analysis report for Down syndrome between 2 - 18 years attending a semi-urban, tertiary medical care centre from 1/1/2013 to 1/1/2015 were included in this hospital based clinical cross sectional study. Detailed ocular examination included visual acuity assessment using age specific tests, diffuse light examination, assessment of ocular alignment, motility, cover tests, slit-lamp biomicroscopy, cycloplegic refraction and direct and indirect ophthalmoscopy. RESULTS In our study, 95 % of children had ocular abnormalities. The most important defects were refractive errors (83.33 %), hyperopia (35 %), myopia 21 % of whom 2 children had high myopia of more than - 6D, and astigmatism (15 %). Among the refractive errors, hyperopia was the commonest. Other ocular abnormalities were cataract (13.33 %), esotropia (13.33 %), exotropia (3.33 %), nystagmus (6.67 %), nasolacrimal duct obstruction (8.3 %) and optic disc coloboma (1.6 %). CONCLUSIONS Refractive errors, strabismus were the most common and significant visual defects identified in children with Down syndrome in our study. Early detection of refractive errors, strabismus and prompt and appropriate intervention like glasses for refractive errors and surgical correction of strabismus is absolutely necessary to prevent development of amblyopia. Improvement of vision accelerates the overall development of the child. Management of Down syndrome children should be a team approach with ophthalmologist playing an important role. These children should have early and regular ophthalmological evaluations to maximise the benefit. KEYWORDS Down Syndrome, Ocular Abnormalities, Visual Acuity in Children

Abstract: Visus is visual acuity. Vision examination is an examination to see visual acuity. Overview vision and blindness remains a substantial social problem in Indonesia. WHO estimates that in 2000 there were 45 million people with blindness in the world, in which one third is in south east asia. With the world's population increases with the increase in life expectancy will increase the number of blindness at least one million people Indonesia reached 1.47%. This study aims to determine visual acuity eye on the students of the Faculty of Medicine, University of Sam Ratulangi. This descriptive study using cross sectional study design (cross-sectional). With the study sample met the criteria is the age of 19-22 years old and healthy while doing research. The samples were students of the Faculty of Medicine, University of Sam Ratulangi numbered 20 people. Based on the research results that show the frequency of eye vision disorders did not differ between the sexes men and women, but the effect on the frequency of vision disorder age. Conclusion: Impaired vision usually occurs due to hereditary factors or behavioral factors that are not well when reading or watching near for a long time and with less lighting.Keywords: visusAbstrak: Visus adalah ketajaman penglihatan. Pemeriksaan visus merupakan pemeriksaan untuk melihat ketajaman penglihatan. Gambaran penglihatan dan kebutaan masih menjadi masalah sosial yang cukup besar di Indonesia. WHO memperkirakan pada tahun 2000 terdapat 45 juta penderita kebutaan di dunia, di mana sepertiganya berada di Asia Tenggara. Penambahan jumlah penduduk dunia dengan peningkatan umur harapan hidup maka jumlah kebutaan akan meningkat paling sedikit satu juta orang Indonesia mencapai 1,47%.
