canthal tilts

Noun

canthal tilt (countable and uncountable, plural canthal tilts)

1. (chiefly medicine or incel slang) The tilt of a line drawn from the outer corner (the lateral canthus) to the inner corner (the medial canthus) of one's eyes; a lower inner corner is referred to as a positive tilt while a lower outer corner is referred to as a negative tilt.
   • The lateral canthal position is normally 2 mm superior to the medial canthal position (i.e., a positive canthal tilt). A negative lateral canthal tilt may indicate descent of the lateral canthus from disinsertion, laxity, or the presence of a prominent eye.2008 January, Andrew P. Trussler, Rod J.
