| Abstract | Purpose: To investigate whether stereoscopic versus monoscopic viewing condition influences evaluation of optic disc photographs for morphologic features and glaucoma likelihood in a general ophthalmologist population from multicenters on a cloud-based platform. Methods: A cross-sectional study. 519 pairs of stereoscopic and monoscopic photographs of optic disc with adequate quality were selected and presented using an cloud-based platform. Twenty-one general ophthalmologists from 14 centers assessed 15 morphologic features based on 5R rules and estimated glaucoma likelihood for each assigned photograph. Main outcome measures were the agreement between estimates and ground truth and the inter-grader agreements. Results: There were good agreements between ground truth and both monoscopic and stereoscopic estimates (stereo κ 0.532 and mono κ 0.494). There was also substantial intra-grader agreement between monoscopic and stereoscopic evaluation of glaucoma likelihood (κ 0.636). In eyes with probable glaucoma, the accuracy of stereo method was greater than that of mono method (stereo 0.238 vs mono 0.118) When compared with ground truth, stereoscopic photographs had better agreement for disc size (stereo κ 0.447 vs mono κ 0.183), disc color (stereo κ 0.612 vs mono κ 0.549), neuroretinal rim shape (stereo κ 0.356 vs mono κ 0.274) on the whole. Stereoscopic method also had better inter-grade agreement for disc size, disc color, neuroretinal rim shape, and glaucoma likelihood (stereo κ 0.402vs mono κ 0.359) on the whole. Conclusions: In the evaluation of optic disc photographs for morphologic features and glaucoma likelihood, stereoscopic method showed superiority compared to monoscopic method for general ophthalmologists. Stereoscopic method is more likely to identify glaucomatous eyes which need medical intervention. |

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.
