The appearance of styes and chalazia may change over time. Care and treatment may also need to be adjusted following your clinician’s advice, while memory alone makes it difficult to judge objectively whether an area is growing, shrinking, or remaining stable.
LidTrack uses the visible width of the iris as a relative reference, helping reduce differences caused by camera distance and image scaling so eyelid appearance is easier to compare over time. Similar angles, lighting, and capture methods produce more consistent trend records.
