Fig. 22 Peters anomaly. Note the central posterior corneal defect with overlying thin, vascularized, scarred stroma. Descemet's membrane and endothelium are absent. Iridocorneal adhesions obscure angle structures and extend almost to the edge of the corneal defect. Lens adheres to posterior cornea centrally (arrow) (PAS, ×4). Inset. Sketch of posterior corneal defect, overlying opacity, iris strands to margin of defect, and anterior polar cataract.
