All the following can be seen in Axenfeld&;s anomaly, except
**Core Concept**
Axenfeld's anomaly is a rare congenital disorder characterized by the presence of a posterior embryotoxon (a prominent anterior displacement of the Schwalbe's line) and iris adhesions to the Descemet's membrane. It is often associated with systemic abnormalities, including glaucoma and developmental anomalies.
**Why the Correct Answer is Right**
Axenfeld's anomaly typically presents with a posterior embryotoxon, which is a result of the abnormal development of the anterior chamber angle. This is due to the premature formation of the Descemet's membrane, which leads to the anterior displacement of Schwalbe's line. The iris adhesions to the Descemet's membrane, also known as iris bands or iris webs, can cause secondary glaucoma. The clinical features of Axenfeld's anomaly are thought to result from the abnormal development of the anterior segment of the eye.
**Why Each Wrong Option is Incorrect**
**Option A:** Not specified - without further information, this option cannot be evaluated.
**Option B:** This option is not correct, as Axenfeld's anomaly typically presents with posterior embryotoxon and iris adhesions.
**Option C:** This option is not correct, as Axenfeld's anomaly is a congenital disorder affecting the anterior segment of the eye, and ectopia lentis is a condition affecting the lens.
**Clinical Pearl / High-Yield Fact**
Axenfeld's anomaly is a rare congenital disorder that often presents with glaucoma and developmental anomalies of the anterior segment. It is essential to recognize the characteristic features of this condition to differentiate it from other anterior segment disorders.
**Correct Answer: B. This option is not correct, as Axenfeld's anomaly typically presents with posterior embryotoxon and iris adhesions.**
