| Abstract | PURPOSE: To assess the correlation between hyperreflective foci (HF) and visual and anatomical outcomes in treatment-resistant neovascular age-related macular degeneration (AMD) using spectral-domain optical coherence tomography (SD-OCT). METHODS: This was a prospective interventional case series. Thirty-three eyes of 30 consecutive patients with treatment-resistant neovascular AMD were enrolled. Intravitreal aflibercept injections were performed at week 0 (baseline), week 4, and week 8. Spectral-domain OCT images were obtained before each injection and 4 weeks after the third injection. The main focus was on the measurement of choroidal neovascularization (CNV) size in the cross-sectional area in the B-scan through the fovea, and HF number along line segments of 1- and 3-mm length passing through the fovea. RESULTS: Mean number of HF in the radius of 500 µm decreased from 8.36 ± 7.58 to 4.15 ± 3.39 (P = 0.02). Mean number of HF in the radius of 1500 µm was reduced from 21.30 ± 12.47 to 10.45 ± 6.34 (P < 0.001). Mean CNV area decreased from 0.35 ± 0.22 to 0.22 ± 0.16 mm2 (P < 0.001). There was a significant positive correlation between HF reduction in the radius of 500 µm and decrease in central subfield thickness (CST) (r = 0.43, P = 0.01), but no statistically significant correlation was found between HF decline in the radius of 1500 µm and other parameters. CONCLUSIONS: Switching from ranibizumab to aflibercept caused significant decrease in the number of HF 1 month after aflibercept upload, and HF decrease in the radius of 500 µm was correlated positively with the reduction in CST. |

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.
