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

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.

Idiopathic inflammatory diseases of orbit and ocular adnexa: Histopathological and immunochemical analysis.

Purpose: : To present histopathological and immunohistochemical analysis of idiopathic inflammatory diseases of orbit and ocular adnexa. Methods: Design- A retrospective laboratory-based study. The study was carried out in an ocular pathology laboratory in a tertiary institute of northeast India where analysis of 93 cases was done in 5 years, during the period from 2011 to 2016. Hematoxylin--eosin and special stains were done for the diagnoses. Immunohistochemistry (IHC) panel was also carried out. For infectious pathology, Grocott's methenamine silver (GMS) stain for fungus, tissue Gram's stain for bacteria's, and acid-fast stains for tubercular bacilli were done. IHC panels were done for CD 20 (B-cells), CD-3 (T-cells), CD-45 (Leukocyte common antigen, LCA), BCL-2, CD-138 (Plasma cells), Kappa, Lambda, IgG-4 in tissue, IgG-4 in serum, etc. IHCs were done using kit methods (standardized) and adequate controls were taken for each sample. Results: 93 cases of nonspecific orbital inflammation were reported out of 1,467 specimens. Orbital pseudotumors (idiopathic orbital inflammatory disease, IOID) were seen in 27 cases (sclerosing variety-6); benign lymphoid hyperplasia in two cases; reactive lymphoid hyperplasia in 10 cases; atypical plasma lymphoproliferative reactive (polyclonal immunophenotypically, IgG4 negative) lesions in four cases; IgG-4 related disease in one case; nonspecific inflammatory reactions (conjunctiva, sclera, and lid) in 49 cases. In all the diagnoses, infections and lymphomas were excluded. Conclusion: Biopsy supported study on nonspecific orbital inflammation was important to know the pattern.
