| Abstract | PURPOSE: To assess changes in choroidal thickness in type 2 diabetic patients with diabetic retinopathy (DR) and diabetic macular edema (DME) using enhanced-depth imaging spectral domain optical coherence tomography (EDI-OCT). METHODS: Among 235 eyes from 145 patients, 195 treatment-naïve eyes were divided into no DR, mild/moderate nonproliferative DR (NPDR), severe NPDR, proliferative DR (PDR), and 40 eyes having a history of laser panretinal photocoagulation (PRP) were classified as PRP-treated DR. Eyes with no ocular treatment (195 eyes) were divided according to the presence of and to the subtypes of DME. Subfoveal choroidal thickness (SFChT) and parafoveal choroidal thickness (PFChT) at 1500 µm were measured using EDI-OCT. RESULTS: Mean age was 62.6 ± 12.4 years, and mean duration of DM was 15.1 ± 7.2 years. Mean SFChT in groups with no DR (40 eyes), mild/moderate NPDR (47 eyes), severe NPDR (72 eyes), PDR (36 eyes), and PRP-treated DR (40 eyes) was 262.3 ± 68.4 µm, 244.6 ± 77.0 µm, 291.1 ± 107.7 µm, 363.5 ± 74.9 µm, and 239.9 ± 57.4 µm, respectively. Mean SFChT was significantly greater in eyes with PDR than in those with no DR (P < 0.01), mild/moderate NPDR (P < 0.01), or severe NPDR (P < 0.05). Mean SFChT decreased significantly in PRP-treated DR compared with PDR (P < 0.01). Eyes with DME (67 eyes) had a thicker subfoveal choroid than eyes without DME (128 eyes; P < 0.05) and, compared with cystoid or diffuse types, SFChT was thickest in subretinal detachment (SRD)-type DME (P < 0.05). CONCLUSIONS: Choroidal thickness increased significantly as the severity worsened from mild/moderate/NPDR to PDR, and decreased in PRP-treated eyes. The subfoveal choroid was thicker in eyes with DME than in those without, and was thickest in eyes with SRD-type DME. |

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.
