A child with aniridia is being placed in your classroom, and you may be wondering whether their needs are different from those of your other students. This information has been written to answer any questions or concerns about this new teaching experience. When a child with a visual disability is enrolled in a regular class, careful consideration is given to assess whether he or she can compete both academically and socially. Although he or she may need to cope with visual and emotional stresses usually not encountered by non-disabled children, he or she will soon become a fully participating member of the class. In order to ensure that the child with aniridia has the opportunity to reach their full academic potential, the child and you will hopefully receive the supportive services of a special teacher of the visually impaired (VI teacher) to discuss classroom situations. A child with aniridia is generally considered eligible for special services of a resource and/or VI teacher if their measured visual acuity is 20/70 or less in the better eye with corrective lenses (in other words, if what he or she can see at twenty feet is no more than what a person with normal vision sees at seventy feet). Children who have a measured visual acuity of 20/200 or less in the better/corrected eye or who have a visual field of no greater than twenty degrees are classified as legally blind. Aniridia is a partial or complete absence of the iris, and it may be associated with other ocular defects such as macular and optic nerve hypoplasia, cataract, corneal surface abnormalities that lead to decreased vision, and nystagmus. The vision may fluctuate, depending on lighting conditions and glare. Glaucoma is a secondary problem causing additional visual loss over time. Because of poor visual acuity and nystagmus, low-vision aids are very helpful. Lifelong regular follow up care is necessary for early detection of any new problem so that timely treatment is given.

Through a questionnaire survey of teachers of special classes for children with low vision in Japan’s primary and lower secondary schools, this study aims to clarify the basic data of children in these classes, the realities of their learning situations, and the realities of the instruction they receive from their teachers. A special class for children with low vision is a class specially organised in primary and lower secondary schools to deliver an education that is appropriate to children with low vision. Basic data items for children covered grade, sex, and visual acuity and also the written characters, low-vision devices, and textbooks that they use in their studies. The survey also elicited responses about the information and communication technology (ICT) devices that teachers use in their teaching, their number of years’ teaching experience, their number of years’ experience teaching children who are visually impaired, and the content or topic of training that they desire to improve their specialisation in the education of children who are visually impaired. In addition to obtaining statistics on basic items related to children’s sex and visual acuity, the results revealed change in children’s actual situations over the years through comparison with the results of previous studies. Specifically, the percentage of children with visual acuity under 20/66 increased, and the usage rate of braille decreased. We also learned that while usage rates of enlarged textbooks and ICT devices are increasing, the rate of using low-vision devices is decreasing. In addition, it was revealed that a majority of teachers had less than 3 years’ experience in education for children who are visually impaired, regardless of general teaching experience, and that there is a considerable need for training in basic knowledge.

Objectives: To investigate the clinical characteristics of cataract patients with small pupils and to evaluate the result of cataract surgery on the eye have small pupils by phacotechnique. Subjects and methods: Descriptive study, prospective, uncontrolled interventions. Sample selection. The sample size of 70 patients with 70 eyes of cataracts with small pupils was treated by phaco technique and intraocular lens implant within posterior chamber. Follow up to 3 months. Results: 70 eyes, the percentage of men and women was not different from 54.2% (38 male) compared to 45.8% (32 female). The mean age was 80 ± 8.74, from 58 to 99 years. The disease was mainly found in the age group over 70 years old with over 80% (51.5%). Visual acuity before surgery was very poor under 3m CF (count finger) for 68.6% (48/70). Visual acuity over 1/10 was only a small amount with 2.8% (2 eyes). Pseudoexfoliation was the most common reason complications of mydriasis with 32/70 eyes (45.7%) and 22/70 eyes (31.4%) for age. The preoperative pupilarysizewas mostly small with 63/70 eyes (90.0%), non-dilated pupils (7/70 eyes) (10.0%). Average pupil size was 3.34 mm (2 - 4mm). Iris condition: iris atrophy 20/10 eyes (28.6%), iris synechiae 11/10 (15.7%), irregular iris muscle with 51, 4% and good iris muscle accounted for 48.6%. Grade of cataract: Grade III: 31/70 eyes (44.3%), Grade IV: 32/70 eyes (45.7%), Grade II: 5/70 eyes (7.1%) and V:2/70 eyes (2.9%). Pupil expander technique: OVD injection with 42/70 eyes (60%), using iris hook with 23/70 eyes (32.9%). Pupillary size before and after intervention has changed from 3.7mm to 4.48mm. Conclusions: Iris expander techniques have been shown to have good dilated pupils: 60.0% OVD injection, iris hook was 32.9%, other methods 7.1% One-week visibility of good visual acuity was higher than that of postoperative one day (12.2%) and increased at 1 month and 3 months (20.0%). Very good visual acuity was not available and low vision group was 1.4% after 3 months. Key words: cataract surgery; phacoemusification, small pupil

<b><i>Introduction:</i></b> Uncorrected refractive errors and amblyopia pose a major problem affecting schoolchildren. We had previously observed that many schoolchildren in the Hatta region presented to the ophthalmology clinic with uncorrected refractive errors and amblyopia, which led us to undertake this research. As per the WHO, the term “visual impairment” can be “low vision” or “blindness.” Based on the presenting vision, “low vision” is defined for children who have vision of &#x3c;6/18 to 3/60 or having visual field loss to &#x3c;20° in the better-seeing eye. Children defined to have “blindness” have presenting vision of &#x3c;3/60 or corresponding visual field of &#x3c;10°. <b><i>Purpose:</i></b> To estimate the magnitude of uncorrected refractive errors and amblyopia among the schoolchildren aged 6–19 years and to assess the efficacy of school-based refractive error screening programs in the Hatta region of the United Arab Emirates. <b><i>Methods:</i></b> An epidemiological, cross-sectional, descriptive study was conducted on the entire student population studying in the government schools of the region. Those who failed the Snellen visual acuity chart test and those who were wearing spectacles were evaluated comprehensively by the researcher in the Department of Ophthalmology of the Hatta Hospital. Data were entered in the Refractive Error Study in School Children (RESC) eye examination form recommended by the WHO, and were later transferred to Excel sheets and analyzed by SPSS. <b><i>Results:</i></b> 1,591 students were screened and evaluated from the end of 2016 to mid-2017. About 21.37% (<i>n</i> = 340) had impaired vision with 20.9% (<i>n</i> = 333) refractive errors, of which 58% were uncorrected. Among the refractive error group, 19% (64 subjects) had amblyopia (4% of total students). The incidence of low vision was 9.5% and blindness was 0.38%. Low vision was found to be 9.5% and blindness 0.38%, taking in to account presenting visual acuity rather than best-corrected visual acuity for defining low vision and blindness. <b><i>Conclusion:</i></b> A significant number of students were detected to have uncorrected refractive errors among the vision impaired group (59%, <i>n</i> = 197) despite a school-based vision screening program in place. Seventy-eight percent of the amblyopia cases (<i>n</i> = 50) were found to be in the 11–19 years age group. Noncompliance with optical corrections was the reason for the high number of cases. A rigorous vision screening program and refractive services, complimented with awareness among parents and teachers, are recommended.

The development and present structure of the comprehensive Low Vision Service of the New York Association for the Blind are used as the basis for a full discussion of the operation of such a clinical service, including its positive and negative features. The clinic is administered by a medical director and by an administrator who coordinates the work of a staff consisting of ophthalmologists, optometrists, low vision assistants, volunteers, registrar, and receptionist. A separate Optical Aids Service stocks low vision aids which it sells by prescription to clinics, doctors, and patients within and without the agency. Referrals for special services are made to the other departments of the agency. Also described are the low vision examination itself, follow-up and training services, and the aid loan system.

The Pandemic of 2020 impacted conducting in-person research. Our proposed project already had an asynchronous online component but was later morphed to add a synchronous online component, thereby eliminating the need for in-person assessment. The project compares the results of various tests between a group of children with Cerebral Visual Impairments (CVI) (N = 4) and an age-matched sample of children without CVI (N = 3) from a pediatric low vision clinic. This model was trialed with a small convenient sample of typically developing children in the same age range (N = 4). Given the positive feedback, recruitment for the larger study was done via encrypted e-mail rather than through traditional mailing. The asynchronous components included recruitment, pre-assessment information, the Flemish CVI questionnaire, Vineland-3 comprehensive parent questionnaire for assessment of age equivalent, and vision function tests, such as contrast sensitivity. The synchronous components were administered via Zoom telehealth provided by necoeyecare.org and included assessment of visual acuity via the Freiburg Visual Acuity and Contrast Test (FrACT) electronic software and assessment of visual perceptual batteries via the Children’s Visual Impairment Test for developmental ages 3–6-years (CVIT 3–6). Our virtual testing protocol was successful in the seven participants tested. This paper reviews and critiques the model that we utilized and discusses ways in which this model can be improved. Aside from public health considerations during the pandemic, this approach is more convenient for many families. In a broader perspective, this approach can be scaled for larger N studies of rare conditions, such as CVI without being confined by proximity to the researcher.

Students’ lateness to school is one of the challenges faced by school administrators. This research therefore investigated the factors responsible for students’ lateness to school as expressed by Nigerian teachers in elementary schools. The influence of moderating variables of sex, years of teaching experience and educational qualification on the respondents’ expressions was also considered. The study is descriptive in nature and sampled 200 Nigerian teachers in elementary schools. An instrument titled ‘Factors Responsible for Lateness to School Questionnaire (FRLSQ’ was adopted to gather data. The descriptive and inferential statistics were used as methods of data analysis. It was revealed that the factors responsible for students’ lateness to school as expressed by Nigerian teachers in elementary schools are poor preparation for school, going late to bed, distance of school from home, high level of poverty, peer pressure, single parenting among others. It is concluded that the factors responsible for lateness to school are enormous. Practical solutions were therefore recommended.

The Impact

Patients’ perspectives on the impact of clinical interventions have been recognised as critical elements in patient care. Quality-of-life instruments are designed to measure these perspectives. We used the National Eye Institute’s 25-item Visual Function Questionnaire (NEI VFQ) to measure the impact of optical low vision devices on the quality of life of 22 low vision patients who obtained and were using low vision devices from a secondary low vision clinic in the Eastern Region, Ghana. The study employed a pre- and post-intervention technique. We found statistically significant improvements in measured visual acuity and NEI VFQ scores in 8 of the 10 domains evaluated. We conclude that optical low vision devices have a positive impact on the quality of life of low vision patients in Ghana.Keywords: low vision; quality of life; visual acuity; visual impairment; Ghana

Aims: To examine the association of weight status with the prevalence of blood pressure (BP), vital capacity, dental decay, and visual acuity among school-age children in Chengdu, China and to find the potential role of weight status to predict the common and frequently occurring diseases among school-age children. Methods: A cross-sectional study was conducted among 12,297 children aged 6-18 years from 10 schools in the Jinniu District of Chengdu, China. Body height, weight, waist circumference (WC), and BP were measured. Vital capacity, dental decay, and visual acuity were detected. Results: The overall prevalence of underweight, overweight, obesity, abdominal obesity, high BP, bad vital capacity weight index, dental decay, and low vision were 7.18, 13.47, 7.57, 18.90, 2.78, 21.93, 38.81, and 45.79%, respectively. After controlling for age, gender, and WC, it was found that overweight and obese children had a higher risk of developing high BP than normal weight children ([OR 4.20, p < 0.001] and [OR 8.76, p < 0.001], respectively), And adjusting for age, gender, and chest circumference, the risk of having bad vital capacity weight index among children with overweight and obesity was higher ([OR 2.15, p < 0.001] and [OR 5.40, p < 0.001], respectively), and the risk with underweight was lower (OR 0.35, p < 0.001). After eliminating the influential factors of gender and age, children who were underweight were 1.16 times (OR 1.16, p = 0.048) more likely to have caries than children with normal weight, but obese children were found to have a lower prevalence for dental cavities than children with normal weight (OR 0.79, p = 0.002). Underweight and obese children had a higher prevalence of low vision; the OR of the appearance of low vision was 1.21 (p = 0.016) for underweight children and 1.23 (p = 0.009) for obese children after adjusting the age and gender. Conclusions: Abnormal weight status among Chengdu urban school-age children was found to be a severe health problem, and it was strongly associated with BP, vital capacity, dental decay, and visual acuity.

Optimal management of eye trauma requires a careful history, a controlled examination, protective measures to limit the damage and prevent infection, and swift triage to an ophthalmologist. Personnel in the emergency department or office can accomplish these goals and save the patient permanent visual disability. How Does One Evaluate Trauma to the Eye? A systematic approach emphasizing history, visual acuity, and external examination are essential in the evaluation of eye injuries. The history should be detailed and should note the mechanism of injury, the events following the injury, preexisting eye disorders, systemic disorders, drug allergies, contraindications to anesthesia, when the patient last ate, and prior tetanus immunization. If ocular perforation, laceration, or intraocular foreign body is suspected, treat the patient as if preoperatively, allowing nothing by mouth, and consider intravenous antibiotics to protect against exogenous endophthalmitis. Visual acuity examination must be performed in every case. Measure the visual acuity in each eye separately with corrective lenses in place. A near card may be used for examination at bedside. Picture cards and charts are available for measuring acuity in children age 3 to 6 years. Preverbal children can be tested grossly by allowing them to reach for a small toy with one or the other eye covered.
