Tube erosion of glaucoma drainage device. Anterior segment optical coherence tomography image. Slit lamp examination revealed an extruded tube of glaucoma drainage device (GDD, Ahmed valve) with melting of scleral patch and conjunctival erosion. (a) Anterior segment optical coherence tomography (OCT) also displayed the GDD tube extrusion and loss of overlying conjunctiva (b).
