Imaging Features of Intraretinal Microvascular Abnormalities in Diabetic Retinopathy (2023)

Posted on

Christian Kim, Jeong W. Pak, Nancy Barrett, Nicole Duncan, Mary K. Wilda, Kristi Dohm, Jen Heathcote, Barbara. A. Blodi, Rick Voland, Amitha Domalpally Abstract Purpose: To compare characteristics of intraretinal microvascular abnormalities (IRMA) on color fundusphotography (CFP) to UWF-FA. We hypothesize that IRMA on CFP have similar characteristics tocorresponding lesions seen on UWF-FA. Methods: Participants …

Influence of Race on Training Data Quality for Artificial Intelligence (AI) Algorithms (2022)

Posted on

Amitha Domalpally, Rick Voland, Robert Slater, Ellie Corkery, Pamela Vargo, Rebecca Kuhtz, James Reimers, Roomasa Channa, Barbara Blodi Abstract Purpose: Diabetic retinopathy (DR) severity level is evaluated from stereoscopic 7-field color photographs by masked graders at the Wisconsin Reading Center and used as a reference standard for training and validation of AI algorithms. Training data …

Implementation of a Large-Scale Retinal Image Curation Workflow Using Deep Learning Framework (2022)

Posted on

Rohit Balaji, Jen Heathcote, Robert Slater, Nancy Barrett, Rick Voland, Vesna Tomic, Jared McDonald, Barbara A. Blodi, Amitha Domalpally Abstract Purpose: The development of artificial intelligence (AI) algorithms for analyzing retinal pathologies requires training based on well-organized, labeled images. The goals of this project are to develop an AI model to curate 7-field retinal photographs …

Artificial Intelligence (AI) enabled pre-screening for Diabetic Retinopathy (DR) clinical trials (2022)

Posted on

Nancy Barrett, Robert Slater, Roomasa Channa, Barbara Blodi, Amitha Domalpally Abstract Purpose: Preventive therapies to reduce progression of non-proliferative DR (NPDR) to proliferative DR are underway. Clinical trial enrollment criteria typically include a baseline DR severity scale (DRSS) of moderately severe (level 47) or severe NPDR (level 53) determined from stereoscopic 7-field retinal color photographs …

Multimodal Imaging Evaluation of Age-Related Macular Degeneration (AMD) in the AMD Ryan Initiative Study (ARIS) (2022)

Posted on

Andrew Dieu, Cynthia Hurtenbach, Jeong W. Pak, Tiarnan D. Keenan, Frederick L. Ferris, Charles P. Wilkinson, Christine Orndahl, Traci E. Clemons, Emily Y. Chew, Amitha Domalpally Abstract Purpose: ARIS is a 5-year, multicenter, international, prospective, observational cohort study of participants with early AMD or reticular pseudodrusen (RPD) to identify novel biomarkers of disease progression. The …

Prevalence and Characteristics of Reticular Pseudodrusen in the Carotenoids in Age-Related Eye Disease Study 2 (CAREDS2) (2021)

Posted on

Jeong W Pak, SC Cleland, Amitha Domalpally, Zhe Liu, Barbara Blodi, S Bailey, K Gehrs, R Wallace, L Tinker, and Julie A. Mares Abstract Purpose: Reticular pseudodrusen (RPD) have been identified as an independent risk factor in the progression of age-related macular degeneration (AMD), particularly predictive of geographic atrophy. However, RPD characteristics are poorly defined …

Ellipsoid Zone Status in Eyes with Retinal Vein Occlusion in the Study of COmparative Treatments for REtinal Vein Occlusion 2 (SCORE2) (2019)

Posted on

Chandana Papudesu, Amitha Domalpally, Neal Oden, Paul Van Veldhuisen, Ingrid U. Scott, Michael S. Ip, Barbara A. Blodi Abstract Purpose: To evaluate the status of the ellipsoid zone (EZ) assessed by spectral domain optical coherence tomography (SDOCT) and its association with visual acuity (VA) in eyes with macular edema secondary to central or hemiretinal vein …

Comparison of Diabetic Retinopathy Severity Level Assessment Between Standard 7-field Imaging and Ultrawide Field Color Imaging (2019)

Posted on

Kristi Dohm, Nancy Barrett, Kyle McDaniel, Barbara Blodi, Amitha Domalpally Abstract Purpose: Diabetic retinopathy has traditionally been evaluated using the Early Treatment Diabetic Retinopathy Severity Scale (ETDRS) from 7-field (7F) stereoscopic color photographs and is considered the gold standard. Ultrawide field color (UWF-C) imaging has recently become available for viewing a wider area of the …

Characteristics of Reticular Pseudodrusen in AREDS2 (2019)

Posted on

Meghana Agni, Jeong W. Pak, Amitha Domalpally, Emily Y. Chew Abstract Purpose: To assess the correlation between peripheral non-perfusion from ultrawide field fluorescein angiography (UWF FA) and Early Treatment Diabetic Retinopathy Severity (ETDRS) level from color fundus photographs (FP) of eyes with diabetic retinopathy (DR). Methods: Capillary non-perfusion was evaluated from UWF FA (Optos) images …

Correlation of peripheral non-perfusion from ultrawide field fluorescein angiography to color ETDRS severity level in eyes with diabetic retinopathy (2019)

Posted on

Ellie Corkery, Kyle McDaniel, Amitha Domalpally, Barbara Blodi Abstract Purpose: To assess the correlation between peripheral non-perfusion from ultrawide field fluorescein angiography (UWF FA) and Early Treatment Diabetic Retinopathy Severity (ETDRS) level from color fundus photographs (FP) of eyes with diabetic retinopathy (DR). Methods: Capillary non-perfusion was evaluated from UWF FA (Optos) images in three …
