Figure 2.53. Anterior segment mes-enchymal dysgenesis in one member of an autosomal dominant (4q28-31) family with variable expressivity is shown in this figure. On the left is an eye with a large area of severe corneal clouding. On the right, the same eye demonstrates the adhesions of the iris to the corneal endothelium.

On the left is an eye with a large area of severe corneal clouding. On the right, the same eye demonstrates the adhesions of the iris to the corneal endothelium.

Figure 2.54. This figure shows anterior segment mesenchymal dysgenesis in members of the same family as in Figure 2.53. On the left is a smaller area of moderate corneal clouding, and on the right is a tiny area of minimal corneal opacity and a central cataract.

Figure 2.55. Aniridia in members of an autosomal dominant (11p13; PAX6) family with variable expressivity is shown in this figure. Neuroectodermal layers of the iris are abnormal. On the left is an eye with complete aniridia. On the right is an eye with an atypical (i.e., any location except inferonasal) iris coloboma.
