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.

Introduction: Visual impairment (VI) in children accounts for great challenge in the life of children that leads to greater medical, psychological, social and economic problems since the child has to live up with handicap for many years to come. Identifying the main causes of visual degradation and their pattern will help in preventive measures, early diagnosis, treatment and rehabilitation of vulnerable population. The aim of this study was to find out the pattern of visual impairment in children attending low vision clinic of Nepal Eye Hospital. Methods: A retrospective cross--sectional review of hospital records of all VI children att ending the low vision clinic from 1st May 2010 to 31st April 2011 with age less than 16 years was done. Results: Overall, 65 children were included in this study with mean age 11.58±3.83 years. Among them 55.4% were male. More than one third (34%) of the total children were in the category of blindness. More than two thirds (72.30%) patients had refractive error. Majority of the patients (66.15%) had multiple causes of visual impairment. Major causes of visual impairment were nystagmus (58.46%), high refractive error (26.15%) and amblyopia (24.61%). Low vision devices were prescribed for only 18.46% of the total patients. Telescope was the most frequently prescribed low vision optical device. Conclusion: Nystagmus, high refractive error and amblyopia were the main causes of VI. Most of the cases had multiple causes. Low vision devices were prescribed for very few of the visual impaired patients and telescope was the most frequently prescribed among them.

INTRODUCTION: Low vision is an important public health problem; however, very few low vision clinics are available to address the needs of low vision patients in most developing countries. The purpose of this study was to describe the characteristics of patients attending the low vision clinic of a tertiary care eye hospital of Western Region of Nepal. METHODS: This was a prospective cross sectional study of all new Nepali patients seen at the low vision clinic over 2 years period. The patients were administered with clinical low vision form (a structured questionnaire) and were examined and tested with low vision devices by the attending low vision specialist. Information on the demographic and clinical characteristics of the patients was recorded. RESULTS: A total of 214 new patients seen during the period were studied. The mean age was 19.80 years, and their ages ranged between 4 and 86 years with a male to female ratio of 2.69:1. Majority (53.30%) were children (≤15years), while 3.70% were elderly patients (≥65years).  The commonest cause of low vision was lens related like pseudophakia, aphakia (20.60%); 18.20% had refractive error/amblyopia; 17.80% had retinitis pigmentosa; macular disorder (20%) and retinitis pigmentosa (20%) were the commonest cause in the adult and elderly patients, while lens related (24.6%) and refractive error/amblyopia (21.1%) were the commonest causes in children.CONCLUSION: The demographic and clinical characteristics of low vision patients seen in this clinic are similar to that of patients in other developing countries, but different from those in developed countries. Elderly patients and females may be under-utilizing low vision services. DOI: http://dx.doi.org/10.3126/jucms.v2i2.11172 Journal of Universal College of Medical Sciences (2014) Vol.2(2): 35-39

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

Introduction: Disability simulation activities are commonly used for various purposes in higher education; however, instructors may be unaware of controversies regarding their use. The purpose of this research was to assess the effects of an activity using low vision goggles to simulate visual impairment in the context of an undergraduate course in special education. We highlight the need for instructors to consider the appropriateness of disability simulation activities given possible countertherapeutic effects. Methods: In this cluster-randomized trial, 11 classes (248 students) of preservice education and related services professionals were randomized to experimental (lecture + simulation) or control (lecture only) conditions. During a single class session, all students received basic information about visual impairment and watched a video on being a human guide. Students in the experimental group then practiced guiding and being guided while wearing low vision goggles. At the end of class, students completed three Likert-type surveys and later completed a quiz using publisher-developed materials. Results: Results showed individuals in the experimental group reported higher levels of interest and enjoyment than those in the control condition; however, there were no statistically significant differences in attitudes toward persons with visual impairments, confidence or self-efficacy for working with students with visual impairments, content knowledge, or perceptions of activity usefulness. Discussion: Findings of positive engagement in the absence of harmful effects indicate that disability simulation activities should be neither promoted nor denigrated wholesale; instead, instructors must weigh carefully potential benefits and drawbacks. Discussion includes considerations for professional education programs in using such simulations to promote skill acquisition via positive and respectful learning experiences. Implications for practitioners: Instructors who use disability simulation activities are encouraged to consider whether to discontinue this practice or incorporate principles recommended by the disability community and assess outcomes to ensure they are not perpetuating harmful stereotypes.

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
