Purpose:
To describe the first case of anterior segment dysgenesis associated with factor VII congenital deficit (hypoproconvertinemia).
Method:
A 2-month-old child with factor VII deficiency was referred to our clinic because of corneal opacities. The child was born to consanguineous parents and severe factor VII deficiency was diagnosed on the third day of life because of gastrointestinal bleeding.
Result:
Ocular examination under anesthesia showed bilateral corneal opacities with adherent iris strands and peripheral anterior synechiae. The intra-ocular pressure was normal in both eyes and there were neither signs of cataracts nor glaucomatous optic nerve damage.
Conclusion:
This observation provide new information on the possible ocular findings in patients with hypoproconvertinemia. Based on this report, we suggest that careful coagulation screening should be considered in children who possess idiopathic anterior segment dysgenesis aiming at identifying the possible coagulation disorder.

The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
