Proposed mechanism hydrogen peroxide penetrated and formed gas anterior to DM Severe cellular damage in the stroma and endothelial layer 1) an inflammatory retrocorneal membrane associated with an organizing hyphema that pulled on DM leading to its detachment.2) retrocorneal membrane develop neovascularization that rupture and fill the space between DM and stroma Not proposed contraction of fibrous exudates pulls on the iris and DM together to its detachment
Associated evidences gas bubble between corneal stroma and Descemet membrane. no normal keratocytes /endothelial cells could be detected by in vivo confocal microscopy a thickened, detached DM associated with a hyphema Accompanied with hyphema AS-OCT showed that the detached DM was thick and adherent to the iris. There is no hyphema
