Introduction to iWellness Exam
A recent ARVO (Association for Research in Vision and Ophthalmology) presentation demonstrated the high sensitivity and specificity of the iWellness Exam.3
Purpose: To determine the ability of the iWellness Exam SD-OCT screening protocol (available on the iVue® SD-OCT, Optovue, Inc. Fremont, CA) to provide data sufficient for a clinician to accurately identify patients with known retinal and/or optic nerve (ON) pathology (sensitivity) and to accurately identify normal, healthy patients as normal (specificity).
Methods: Two groups of patients were examined: A “Confirmed Normal” (CN) cohort for the specificity aspect of the study, and a “Confirmed Disease” (CD) cohort for the sensitivity aspect of the study. 105 of the 111 CN and 102 of the 108 CD subjects were included for analysis. Of the CD patients, 68 had retinal pathology; 50 had ON pathology. (Sixteen (16) fell into both categories, with both retinal and ON pathology).
All subjects were screened on the iWellnessExam protocol. Screenshots of the OD, OS, and OU comparison data were obtained and de-identified for reviewer analysis by a well-trained eye care clinician. Based on these data alone, each subject was sorted into one of four categories: (1=Normal, 2=Retinal disease, 3=ON disease, 4=Retinal+ON disease).
