Extensive Descemet’s membrane detachment on ultra-widefield swept-source OCT

A 61-year-old female patient underwent cataract phacoemulsification and intraocular lens implantation in her left eye. During a follow-up examination 1 week postsurgery, significant corneal edema and extensive detachment of Descemet’s membrane (DM) were observed in the left eye. Ultra-widefield swept-source OCT (SS-OCT) revealed a corneal thickness of 1011 μm Fig. 1. Descemet’s membrane detachment (DMD) refers to the separation of the DM from the posterior stroma, resulting in fluid accumulation in the pre-Descemet’s space, which leads to stromal and epithelial edema and a consequent decrease in vision.1,2 Following air descemetopexy, the cornea cleared, and the DM separation line became clearly visible. The DM was fully reattached, and the corneal thickness decreased to 512 μm Fig. 1. One week post-treatment, the visual acuity in the left eye improved from counting fingers to 20/20 Fig. 2.Figure 1: Ultra-widefield SS-OCT revealed a significant detachment of DM, with a diameter of 7849 µm in the central region of the left eye. This detachment was associated with an increase in corneal thickness to 1011 µm, and the presence of epithelial blisters was notedFigure 2: The cornea was clear, the air was completely absorbed, and the DM separation line was clearly visible (yellow arrow) after 1 week of the air injection (our picture has been enlarged by 300%)Authors contributions Meiqi Fan: Conceptualization, Methodology, Writing - original draft.
