Causes of Severe Visual Impairment and Blindness in Schools for the Blind

An estimated 19 million of the world's children are visually impaired, while 1.4 million are blind, according to the World Health Organization (WHO) criteria. [...]the control of visual impairment or blindness (VI/BL) in children is still one of the priority areas of the WHO's “Vision 2020: the Right to Sight” program. According to the WHO Prevention of Blindness (WHO/PBL) Examination Record for Children with Blindness and Low Vision, the data on personal/demographic details, brief family history, presence of other disabilities, medical history, previous eye surgery, and eye examination were collected from the children's medical records. Lack of cognitive ability and compliance, the inconvenience of LVAs, and gradually adapting to the environment made them discontinue the use of LVAs. [...]a multidisciplinary team of ophthalmologists, optometrists, rehabilitation therapists, teachers, and parents is required for childhood low-vision rehabilitation. [...]the sample of children examined in this study must be viewed as a selected group having a bias.
