Outcome Measures
Primary Outcomes (4)
Comparison of the total number of Relspec images annotated for GA lesions
Comparison of the total number of Relspec images annotated for GA lesions of at least 29 pixels or larger with the total number of OCT images with identified GA lesions (cRORA) in the Test Dataset.
45 days
Comparison of the total number of 'high certainty' GA lesions
Comparison of the total number of 'high certainty' GA lesions (Yellow label) of at least 29 pixels annotated in all Relspec images with the total number of (cRORA) identified in the OCT images in the Test Dataset.
45 days
Comparison of the total number of GA lesions
Comparison of the total number of GA lesions (Yellow label and Dark Blue label) of at least 29 pixels or larger annotated in all Relspec images with the total number of identified GA lesions (cRORA) in the OCT images in the Test Dataset.
45 days
Evaluation of the Global DICE Score
Evaluation of the Global DICE Score for annotations of 29 pixels or larger performed by CapeStart compared with the Reference Data.
45 days
Study Arms (3)
Cohort A
Eyes of patients with a diagnosis of dry AMD with GA lesions
Cohort B
Eyes of patients with a diagnosis of AMD without the presence of RPE disruptions
Cohort C
Eyes of age-matched healthy patients (no AMD or GA lesions)
Interventions
Retrospective Study This study will use a retrospective Test Dataset of eye scans collected by Optina under different study protocols. MHRC H5 Images collected as part of Optina studies CIP-22-003, CIP-22-004, DOC100463 or RWD-24-011 will be reviewed by an Optina Data Analyst and flagged for potential match to the Target Population. Of the flagged images, 40 will be selected and allocated to the Test Dataset. All selected images must have a matching OCT image for review as part of the Reference Data. The Test Dataset will be documented in the CIP-24-015 data spreadsheet and archived in the CIP-24-015 central files.
Eligibility Criteria
This study will use a retrospective dataset collected by Optina under different study protocols. The target study population will include adults over the age of 50 years, with and without the presence of AMD.
You may qualify if:
- Study participants over the age of 50 years who consented to participate in Optina studies CIP-22-003, CIP-22-004, DOC100463, or RWD-24-011.
- MHRC H5 Image Cube has been reviewed by an Optina Analyst and identified as aligned with the Target Population (see Section 5.2).
- MHRC H5 Image Cube has a corresponding OCT image.
