Assessment of quality of life, mental health and ocular morbidity in children from schools for the blind in North-East India

Abstract

Purpose: The aim of this study was to describe causes of severe visual impairment and blindness (SVI/BL), and assess the mental health and quality of life of children in schools for the blind in North-East India in two phases. Methods: A total of 515 children were examined in 17 schools for the blind in the first phase of study across eight states in North-East India, 6 in Assam, 2 each in Meghalaya, Manipur, Mizoram, and Tripura, 1 each in Arunachal Pradesh, Nagaland, and Sikkim. WHO/PBL eye examination record was used to document findings. In the second phase of study, mental health and quality of life were objectively measured using depression anxiety stress scales (DASS) and low-vision quality of life (LVQOL) questionnaires in 442 children. Results: Approximately 3.1% of children had SVI and 71.84% of children were blind. Anatomical sites of SVI/BL were the whole globe in 44.85%, cornea in 17.66%, and retina in 11.65% of children. The underlying cause of visual loss was undetermined in 55% of children. Hereditary pattern was observed in 1.35% of cases. Approximately 74.94% of children were either blind or severely visually impaired since birth. DASS score revealed that 56.56% of children manifested some levels of anxiety and stress while 85.52% had some reduction in quality of life. Conclusion: A large significant number of these children suffered from potentially preventable and/or treatable cause of SVI/BL. Though nonvisual factors such as physical and mental health were strong predictors of quality of life, this study proves that visual impairment also plays a considerable role in one's quality of life in a population with low vision.
