Anatomy
Medial Canthus (Inner Corner / Nasal Canthus)
The medial canthus is the inner corner of your eye, closest to your nose. This area contains the tear drainage system (lacrimal puncta) that removes tears from your eye and sends them down through tear ducts to your nose. When tear ducts get blocked, it can cause tearing and irritation.
