Lens abnormalities. (A) Lenticonus appearance on slit-lamp examination showing an anterior dimple or oil droplet (arrow) in a man with X-linked Alport syndrome, renal impairment, and posterior polymorphous corneal dystrophy. The oil droplet is also obvious on direct ophthalmoscopy. (B) Anterior segment view showing the anterior bulging of the lens (arrows) with a Scheimpflug camera (Pentacam) in the patient from A. (C) Electron microscopy of an anterior lens capsule obtained at surgery showing the thinned capsule (arrow) and vertical tears (upper panel) compared with normal (arrow in lower panel). The abnormal lens was from a man with X-linked Alport syndrome, renal failure, lenticonus, and retinopathy.
