Ultrasound biomicroscopy-guided assessment of acute corneal hydrops

Abstract

Objective: To analyze the morphologic features of acute hydrops and treatment success using ultrasound biomicroscopy (UBM). Design: Prospective interventional case series. Participants: Fourteen patients (14 eyes) affected by keratoconus with acute corneal hydrops. Intervention: Patients with acute hydrops were treated with intracameral injection of 0.15 ml of 14% perfluoropropane (C 3F 8) gas. Main Outcome Measures: The parameters evaluated on UBM included the location and length of the Descemet's membrane (DM) tear and corneal thickness at the central corneal thickness at the area overlying the DM tear (CT 0), corneal thickness 2.5 mm from the central point (CT 2.5), and peripheral corneal..
