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 Background Refractive errors and visual impairment in southernmost China have not been reported previously. We aim to investigate and determine the age-specific prevalence of myopia, hyperopia, astigmatism, and visual impairment based on a large population cross-sectional study in Hainan area of southernmost tropical province in China. Methods A population-based sample of 31,524 children aged 6–15 years from Hainan was assessed. Non-cycloplegic autorefraction and visual acuity (VA) analyses were performed on all participants and a subgroup of participants undergoing cycloplegia. Results Of all participants, 23.0% presented uncorrected VA (UCVA) was worse than 20/40 in worse eye, 6.0% presented mild presenting visual acuity impairment (PVAI), 7.0% presented moderate PVAI, 0.2% presented severe PVAI in the better eye, and 46.9% presented abnormal UCVA [worse than 20/25 (≥ 6, < 8 years old) and worse than 20/20 (≥ 8 years and older)] at least in one eye. The overall prevalence of myopia [spherical equivalent (SE) ≤  − 0.50 D] and high myopia (SE ≤  − 6.00 D) were 46.0%, 1.0% respectively. Hyperopia [SE ≥  + 1.00 D (≥ 7 years old) and SE ≥  + 2.00 D (≥ 6, < 7 years old)] and significant hyperopia (SE ≥  + 3.00 D) were 4.2 and 0.6%, respectively. Astigmatism [cylinder ≥ 1.00 D (≥ 7 years old) and ≥ 1.75 D (≥ 6, < 7 years old)] was found in 31.9%. Conclusions Myopia was the most common refractive error in southernmost province in China (Hainan). Its prevalence increased with age, while hyperopia prevalence showed a decreasing trend. However, myopia, especially high myopia prevalence was much lower than in other urban regions across China.

OBJECTIVES:The objective of our study was to determine the prevalence of refractive errors among children of special education complex. METHODOLOGY:A cross-sectional study was conducted to determine refractive error among the children of special education complex Hayatabad, Peshawar. A total of 272 children were examined from age 5-19 years. Refractive errors were determined by doing retinoscopy, subjective and objective refraction, ophthalmoscope and, hand held auto refractors. Snellen’s charts, lea symbol chart and kay pictures were used for assessing the visual acuity in children who could cooperate. RESULTS:Among 272 children, 225 children were males (82.7%). 34(12.5%) were mentally retard, 182(66.9%) were hearing impaired and 56(20.6%) were physically handicapped. Children suffering from refractive errors were 47(17.3%). 11(4.0%) reported that they were using glasses. Squint was present in 5(1.8%). On examination status of right eye 5(1.8%) were with visual acuity 6/60 or less. For children who were unable to comprehend with Snellen visual acuity chart, they were be assessed by using other charts like Lea symbol chart or Kay pictures. 19(7.0%) were assessed by Lea symbol chart, 9(3.3%) by Kay pictures and maximum number of children easily understand Snellen visual acuity chart that was 244(89.7%). CONCLUSION:This study concluded that refractive errors were common in special children.

Many studies have established a relationship between visual function and motor development in toddlers. This is the first report to study two-year-olds via an assessment of their visual and motor skills. The purpose of this study is to describe the possible changes that can occur between visual and motor systems in typical developing toddlers. A total of 116 toddlers were included in this observational, descriptive, and cross-sectional study. Their mean age was 29.57 ± 3.45 months. Motor development variables studied were dominant hand/foot; stationary, locomotion, object manipulation, grasping, visual motor integration percentiles; gross motor, fine motor, and total motor percentiles; and gross motor, fine motor, and total motor quotients. Visual development variables were assessed including visual acuity, refractive error, ocular alignment, motor fusion and suppression, ocular motility, and stereopsis. Our findings demonstrated that typical developing toddlers with slow gross motor development had higher exophoria and further near point of convergence values compared to toddlers with fast gross motor development (p < 0.05). No statistically significant differences were found in visual acuity and stereopsis between slow and fast gross motor development toddlers.

Introduction: Mental disorders are changes in psychological, mental or cognitive functioning, in which there is impairment, or suffering that impairs life habits, family, social interaction, among others. Objective: To trace the epidemiological profile of psychiatry patients of Gurupi polyclinic -TO. Materials and Methods: Descriptive cross-sectional study with a quantitative approach, performed from the analysis of 104 medical records of patients in the psychiatric specialty attended at Gurupi-TO polyclinic. Data were collected on gender, age, the city of origin, the profession, marital status and medical diagnosis. The data were analyzed from descriptive statistics, in absolute and relative values. Results: It was observed that people aged 6 to 84 years were observed, most of them female (63.5%). In addition, it is noticed that polyclinic users are mostly single (70%), residents of Gurupi city (84%). Regarding the profession, a high percentage of medical records do not contain these responses (58%), of the others are mostly from home (15%). The most prevalent disorders are bipolar affective disorder (34.2%) and depression (27.9%). Conclusion: It is possible to realize that psychiatric disorders are predominantly affecting female patients, aged between 30 and 49 years, single, as a profession of "home", with fixed residence in the city of Gurupi and diagnosed predominantly with mental pathologies related to bipolar affective disorder and depression.

BACKGROUND Brain tumours represents 1.7 % of all cancers and contributes 1.8 % of all cancer deaths. Of all the brain tumours, 80 % are supratentorial.1 Magnetic resonance imaging (MRI) is an important modality, having higher sensitivity for detecting intracranial pathology. Multiplanar imaging is possible with MRI which helps in detection, localization and characterization of the lesion. MRI examination has helped in early diagnosis, accurate localization of the tumour, with prompt initiation of appropriate medical or surgical therapy. Recent advances like magnetic resonance (MR) spectroscopy, MR fluoroscopy with stereotactic guided biopsy have revolutionized the role of MRI in study of intracranial tumours. METHODS A cross sectional study of 75 patients was done by Siemens Essenza 1.5T MRI from June 2018 to June 2020 using dedicated head coil. RESULTS In our study, most of the patients were between 31 - 60 years of age (39 % of all patients) with the largest group between 31 - 40 years (20 % of all patients). Out of 75 cases of supratentorial neoplasms, 47 (72 %) were intra-axial lesions, 15 (23 %) were extra-axial lesions and 3 (5 %) were intra ventricular lesions. In this study, 69 % of the lesions were solitary and 31 % were multiple. Most of patients (89 %) showed some enhancement, most common being heterogeneous/inhomogeneous enhancement. Commonest type of supratentorial neoplasms were metastases comprising 29 % of this study. CONCLUSIONS Magnetic resonance imaging is an important modality, having higher sensitivity for detecting intracranial pathology. Multiplanar imaging is possible with MRI which helps in early detection, localization and characterization of the lesion. Metastasis is the most common supratentorial tumour in this study followed by meningioma. Intra-axial tumours are more common than extra-axial tumours in this study.
