“…The authors identified the degree of visual loss and the severity of intellectual disability as good predictors for ASD, and recommended that children with SOD/ONH would benefit from routine ASDs screening. De Verdier et al [33] described neurodevelopmental impairments in children with congenital or early infancy blindness born over a decade in Sweden; they found that ASD was one of the most common additional impairment (38% of these population) and that the prevalence was higher in children with ONH (70%), in children with ROP (58%), in children with microphthalmia/anophthalmia (44%), and in children with LCA (36%).…”

Autistic-Like Features in Visually Impaired Children: A Review of Literature and Directions for Future Research

There remains great interest in understanding the relationship between visual impairment (VI) and autism spectrum disorder (ASD) due to the extraordinarily high prevalence of ASD in blind and visually impaired children. The broad variability across individuals and assessment methodologies have made it difficult to understand whether autistic-like symptoms shown by some children with VI might reflect the influence of the visual deficit, or represent a primary neurodevelopmental condition that occurs independently of the VI itself. In the absence of a valid methodology adapted for the visually impaired population, diagnosis of ASD in children with VI is often based on non-objective clinical impression, with inconclusive prevalence data. In this review, we discuss the current state of knowledge and suggest directions for future research.

Mathematical education is currently undergoing significant changes that are driven by technology and digital-based learning. Students with visual impairments (VI) may face different challenges in mathematical education due to a lack of accessible materials designed to support the development of conceptual understanding in mathematics. The aim of the study was to summarize current evidence-based knowledge about e-learning in mathematics among students with severe VI. A systematic review was conducted of articles published from January 2000 to November 2017. A total of 13 publications met the inclusion criteria, of which 12 reported studies with an intervention or an experimental design and one had a cross-sectional design. The number of students with VI varied from three to 16 ( Mage = 19 years). Four publications reported either ophthalmic diagnoses or World Health Organization’s (WHO) definition of vision loss. The mathematical training was reported as lasting from one session to 18 weeks of training. Eight papers reported the use of audio-based applications as learning aids. The authors conclude that interactive e-learning with audio and tactile learning programmes may be a useful resource for students with VI to enhance their mathematical skills. However, there is lack of evidence for how digital technologies improve inclusion potentials and learning in mathematics for students with VI, and hence, there is a need for additional research and more reflection on the subject.

“…The prevalence of childhood blindness varies according to socioeconomic status [ 12 ]. In very low income countries with high mortality rates in children younger than 5 years, the prevalence may be as high as 1.5 per 1000 children, in contrast with high-income countries where the prevalence is five times less [ 13 ].…”

The aim of the study was to highlight the medical and legal difficulties in framing lowvision patients for certification. We performed a retrospective observational study conducted from January 2013 to January 2016, on 63 patients with the mean age of 16.37±3.34 years, evaluated at the Ophthalmology Clinic from "Sf. Spiridon" Hospital, Iași, in order to release a medical certificate required at the Expertise Board. The clinical parameters observed were visual acuity (VA) with correction, objective refraction (in Spherical Equivalent -SEq), intraocular pressure, slit lamp examination of the anterior pole, fundus examination, orthoptic eye exam, and ocular ultrasonography (in selected cases). The main causes for the decreased visual acuity found are refractive or strabic amblyopia determined by: high myopia (28.57%), esotropia (19.04%), astigmatism (17.46); congenital diseases -congenital nystagmus (12.69%), congenital cataract (7.93%), microphthalmia (7.93%); acquired diseases -retinopathy of prematurity (9.52%), optic nerve atrophy (7.93%), bandelette keratopathy (6.34); ocular trauma (7.93%). In 52.38% of the cases for the RE and 53.96% of the cases for the LE, decreased visual acuity was caused by an irreversible condition and could not be improved. Patients come every year for reevaluation in order to receive the medical certificate required at the Expertise Board. Evaluating the patient for a certificate for visual impairment is a time consuming process due to the high number of investigations necessary and, sometimes, difficult collaboration with the patient with associated general pathology. It also requires knowledge of frequently changing legislation to complete legal forms for patients with visual impairment. A medical certificate may now be issued with a validity of up to four years, given that certain diseases are irreversible and visual functional status does not change over time.
