Abstract

The cyclodialysis cleft is a rare complication (2 %) in the spectrum of blunt trauma presenting ocular hypotony. This is a separation between the ciliary body and the sclera. This results in the formation of a new space between the anterior chamber and a suprachoroidal space, often inducing major ocular hypotony. Treatment requires medical treatment or even surgical treatment for severe cases. A certain degree of recession of the iridocorneal angle could persist after closure of the cleft of cyclodialysis, causing at short- or at long-term ocular hypertonia.

La fente de cyclodialyse est une entité rare du spectre des traumatismes à globe fermé présentant une hypotonie oculaire (2 %). Il s’agit d’une séparation entre le corps ciliaire et la sclère. Il en résulte la formation d’un nouvel espace entre la chambre antérieure et l’espace supra-choroïdien, favorisant une hypotonie oculaire parfois majeure. La prise en charge requiert un traitement médical, voire chirurgical pour les cas sévères. Il persiste souvent un certain degré de récession de l’angle irido-cornéen après la fermeture de la fente de cyclodialyse. Cette récession d’angle peut être à l’origine d’hypertonie oculaire à court ou long terme.
