Etymology

dis- +‎ insertion

Noun

disinsertion (plural disinsertions)

1. A tear (rupture) near the periphery of the retina.
   • 1944, Edmund Benjamin Spaeth, The Principles and Practice of Ophthalmic Surgery, page 796:

     While disinsertions are probably due to peripheral cystic degeneration of the retina or to peripheral degenerative chorio-retinitis, traumatic tears which appear in the pre-equatorial zone may simulate disinsertions.
