About this trial
This study will measure how well PathFinder 1.0 detects retinal abnormalities on macular cube OCT B-scans by assessing its sensitivity and specificity.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Able and willing to make the required study visits.
Able and willing to give written informed consent and follow study instructions.
Able and willing to complete ophthalmic imaging.
Adults 18 years of age or older.
Disqualifiers
Inability to undergo the required tests.
Unable to give consent or follow study instructions.
Inability to fixate that precludes obtaining acceptable macula scans in the study eye.
Visudyne (verteporfin) injection within the last 48 hours in the study eye.
Trial design
Single group
Treatments tested in this trial
PathFinder 1.0 on CIRRUS HD-OCT
DeviceParticipants undergo standard OCT imaging on CIRRUS HD-OCT systems, and the investigational PathFinder software analyzes the images for macular abnormalities without influencing clinical care.
Treatment groups
Trial outcomes
Primary outcomes
Sensitivity of PathFinder 1.0
Sensitivity is the proportion of scans that PathFinder 1.0 correctly identifies as having any macular abnormality.
Specificity of PathFinder 1.0
Specificity is the proportion of scans that PathFinder 1.0 correctly identifies as having no macular abnormality.
Secondary outcomes
Sensitivity and specificity by clinical diagnosis
Sensitivity and specificity of PathFinder 1.0, calculated separately within each PI-recorded diagnosis group.
Sensitivity by macular abnormality type
Sensitivity of PathFinder 1.0 calculated separately for each OCT lesion type.
Positive Predictive Value and Negative Predictive Value
Positive Predictive Value is the proportion of B-scans called abnormal by PathFinder 1.0.
Rate of acceptable versus unacceptable B-scans
Proportion of B-scans within each macular cube, and overall, that is marked as "acceptable" or "unacceptable".
