- Vessel Integrity: Assess rakehell vessel crossings for signs of vein occlusion.
The software compares these ikon against thousands of salubrious retinal scan to observe anomaly that the naked eye might miss when looking through a screen.
๐ Note: It's vital to take contact lens before the camera bust the retinal pic, as lense can create reflections and twine the view of the cornea.
Is Accuracy Comparable to In-Person Visits?
This is the question everyone ask. The little response is: yes, but with caution. For a simple deflexion (determining if you demand glasses), virtual test are often just as exact as standard machine-based tests launch in retail memory. Withal, they aren't a replacing for a hands-on dilated exam.
