| Abstract | BACKGROUND: To assess the impact of cataract on quality of life (QoL) for patients with glaucoma. DESIGN: Cross-sectional study. PARTICIPANTS: Two hundred forty-two patients with mild (n = 67), moderate (n = 80) or severe (n = 45) glaucoma and 50 controls (glaucoma suspects). Patients with cataract of any severity were included. METHODS: The following data were collected: sociodemographic information, phakic/pseudophakic status, cataract grade according to the Lens Opacities Classification System (LOCS) III, visual acuity and visual field test parameters. Glaucoma severity was stratified according to binocular visual field loss. Visually significant cataract was defined as: LOCS III criteria nuclear cataract ≥3/6.9, cortical cataract ≥3/5.9 or posterior subcapsular cataract ≥2/5.9. MAIN OUTCOME MEASURES: Patients' QoL was measured using Rasch-transformed scores from the Glaucoma Activity Limitation-9 (GAL-9) questionnaire. Multiple linear regression models were used to determine the association between cataract and GAL-9 (logit) score. RESULTS: Fifty-six (23.1%) patients had at least one visually significant cataract. At least one visually significant cataract (standardized coefficient [ß] 1.19, 95% confidence interval 1.04-1.34, P = 0.011) and poor visual field index (better eye) (ß 1.47, 95% confidence interval 1.36-1.88, P < 0.001) were independently associated with worse GAL-9 score. CONCLUSIONS: Cataract influences glaucoma-related QoL among glaucoma patients of all severity levels and is an important cause of potentially reversible visual impairment among glaucoma patients. The Rasch-analysed GAL-9 questionnaire is a useful metric to quantify visual disability related to cataract in glaucoma patients. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
