A corneal tulip? Assessing corneal opacities in Lisch corneal epithelial dystrophy

We wish to demonstrate the variety of imaging techniques available to help the clinician in the assessment of microcystic corneal opacities, through clinical pictures, anterior segment optical coherence tomography (AS-OCT), topography, confocal microscopy and histological and electron microscopy, confirming the rare diagnosis of Lisch corneal epithelial dystrophy. This case also provides a clinical illustration that the abnormal cells, which are responsible for the superficial epithelial opacities of Lisch corneal dystrophy, appear to originate from the limbus.
