The diagnosis of<unk>  is often made with slit lamp biomicroscopy. With direct illumination, the clinician can visualize guttae, the characteristic pathological changes in disease. Scheimpflug imaging, anterior segment optical coherence tomography, confocal microscopy, and specular microscopy are additional imaging techniques that can identify the presence of guttae and quantify the thickness of the cornea. While corneal thickness can be a valuable indicator of how the cornea is changing over time, it is affected by multiple factors and is not adequate itself as a screening tool to diagnose<unk> .
