Standardizing Retinal Thickness Measurements Across Spectral Domain Optical Coherence Tomography (SDOCT) Machines – 5 Point Measurement Method (2011)

Posted on

Dawn Myers, Amitha Domalpally, Jill C. Kubiak, Qian Peng, Ronald P. Danis Abstract Purpose: The outer boundary line (BL) location differs among SDOCT vendors making it difficult to compare retinal thickness data in clinical trials. No automated software is commercially available that can segment a common BL from all SDOCT types. Manual segmentation of BLs …

Green Channel vs. Color Retinal Images for Grading Diabetic Retinopathy in DCCT/EDIC (2010)

Posted on

James L Reimers, Sapna Gangaputra, Barbara A. Esser, Trina M. Harding, DW Thayer, Qian Peng, Larry D. Hubbard , Ronald P. Danis Abstract Purpose: To compare diabetic retinopathy (DR) severity levels from green channel (GrCh) fundus images (simulating red free) with full color (Red/Green/Blue) images. Methods: From the Diabetes Control and Complications Trial/Epidemiology of Diabetes …

Morphological Assessment of Fundus Color Images for the Multicenter Uveitis Steroid Treatment (MUST) Trial (2010)

Posted on

Susan Reed, Sapna Gangaputra, Amitha Domalpally, Qian Peng, Michael Altaweel, and the Multicenter Uveitis Steroid Treatment (MUST) Trial Research Group Abstract Purpose: To describe the uveitis grading program and report the reproducibility of evaluation procedures for color fundus images in the MUST Trial.

Association of Outer Retinal Layer Morphology with Visual Acuity in Patients with Macular Edema Secondary to Retinal Vein Occlusion – A SCORE Study Ancillary Study (2010)

Posted on

Amitha Domalpally, Qian Daisy Peng, Ronald P Danis, Barbara Blodi, Ingrid U Scott, Michael Ip, and SCORE Study Research Group Abstract Purpose: To evaluate the relationship between outer retinal morphology assessed by optical coherence tomography (OCT) and visual acuity (VA) in patients with macular edema secondary to retinal vein occlusion. Methods: High resolution cross hair …

Evaluation of 4 Wide Digital Images for Diabetic Retinopathy (2010)

Posted on

Trina M. Harding, Sapna Gangaputra, James L. Reimers, Qian Peng, Ronald P. Danis Abstract Purpose: The 4 Wide Angle Fields (4W) Digital fundus imaging protocol is designed to capture approximately the same retinal area as the ETDRS 7 modified fields (7M) protocol, but with fewer images. We sought to evaluate the grading procedure and reproducibility …
