| Abstract | PURPOSE: To compare the posture-induced intraocular pressure (IOP) changes in eyes with open-angle glaucoma (OAG), primary angle closure (PAC) with or without glaucoma medications, and healthy control eyes with normal IOPs. METHODS: The IOP was measured in the sitting position (SP) and the lateral decubitus position (LDP) with a rebound tonometer. The IOP in the LDP was measured in the upper eyes 5 minutes after assuming this posture. RESULTS: Fifty-two patients with OAG, 52 with PAC, and 52 controls with normal IOPs were studied. The IOP in the SP measured with the rebound tonometer was 14.3 ± 4.0 mm Hg in eyes with OAG, 15.8 ± 4.5 mm Hg in eyes with PAC, and 13.9 ± 3.7 mm Hg in eyes with normal IOPs. None of these differences was significant (P = 0.060; ANOVA). The IOP in the LDP was significantly increased to 18.3 ± 4.6 mm Hg in eyes with OAG, 19.3 ± 4.4 mm Hg in eyes with PAC, and 17.3 ± 3.5 mm Hg in eyes with normal IOPs (P = 0.000 for all; paired t-tests). The postural IOP difference was +4.0 ± 2.2 mm Hg in OAG eyes, +3.5 ± 2.2 mm Hg in PAC eyes, and +3.4 ± 1.8 mm Hg in normal eyes, and these increases were not significantly different among the three groups (P = 0.309; ANOVA). The correlation between the posture-induced IOP changes and the axial length was not significant in each group. CONCLUSIONS: Postural IOP changes are comparable among eyes with OAG, PAC with and without glaucoma medications, and control eyes. |

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.
