Peters' anomaly is presumed to occur when separation of the lens vesicle from the surface epithelium fails or is delayed. Other ocular anomalies, mainly of the anterior segment, usually are accompaniments. The clinical and pathological findings are described in a patient who presented with this condition bilaterally. He also showed an unusual coloboma of the retinal pigment epithelium and choroid, covered by dysplastic retina involving the entire posterior half of the eye.
