Fig. 6. Axenfeld's anomaly (posterior embryotoxin). A. The only abnormality visible from the 2-o'clock to 4-o'clock positions adjacent to the limbus is a “ropy” corneal opacity. The other eye is normal. B. A corneal opacity is present over 360 degrees near the limbus at the level of Descemet's membrane. C. Scanning electron micrograph shows the iris processes spanning the angle and attaching to the anteriorly displaced Schwalbe's ring. Artifactually broken ends of the iris processes are indicated by the arrows. D. Macroscopic appearance of the iris processes attaching to Schwalbe's ring. E. Iris processes attach to the anteriorly displaced Schwalbe's ring. (Courtesy of SEI Photoarchives.)
