Idiopathic loss of lateral tarsal suspension

CASE: A 53-year-old man who showed a loss of tarsal suspension in the lateral third of both lower eyelids underwent lateral canthoplasty with a good post-operative result. DISCUSSION: Disinsertion of the union of the inferior tarsus with the lateral canthus, of unknown cause, is a very uncommon finding that has almost never been reported in the world literature. There are two cases described of eyelid elastolysis with loss of lateral tarsal suspension, as in our case, but both showed eyelid skin atrophy and had histopathologic confirmation. Our case did not have skin atrophy.
