| Abstract | PURPOSE: To report the optical coherence tomographic features differentiating choroidal nevus from choroidal melanoma by 3D spectral-domain optical coherence tomography (SD-OCT) and OCT characteristics of other choroidal tumors. METHODS: A total of 67 consecutive eyes with choroidal tumors including choroidal nevus (25 eyes), indeterminate choroidal melanocytic lesion (11 eyes), malignant melanoma (23 eyes), metastasis (4 eyes), hemangioma (2 eyes), and osteoma (2 eyes) were imaged with 3D SD-OCT (OCT-1000; Topcon Inc., Paramus, NJ). The images were analyzed for the presence or absence of SD-OCT findings such as retinal pigment epithelium (RPE)/choriocapillaris reflectivity, RPE irregularity, drusen, sub-RPE fluid, RPE thickness, subretinal deposit, subretinal fluid, intraretinal edema, retinal thickness, and photoreceptor inner and outer segment junction (IS/OS). Visualization of the choroidal tumor and its intrinsic reflectivity OCT features were also assessed. RESULTS: When compared with nevus, subretinal deposit, subretinal fluid, and intraretinal edema were detected significantly more frequently in the eyes with malignant melanoma (p<0.001). SD-OCT visualization of the tumor was limited only to the anterior aspect. Choroidal nevus, indeterminate lesions, melanoma, and metastatic lesions had variable intrinsic reflectivity pattern. Intrinsic features of hemangioma included choroidal hollowness whereas osteoma demonstrated high intrinsic reflectivity. CONCLUSIONS: SD-OCT provides useful information to observe and document the retinal and RPE changes secondary to choroidal tumors that help differentiate choroidal nevus from malignant melanoma. Improvements in the current OCT systems are needed to better characterize intrinsic features of choroidal tumors. |

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.
