PCG has a predominantlyautosomal recessive inheritance pattern with a polygenic aetiology, andCYP1B1, LTBP2, MYOC, FOXC1 and TEK genes havebeen involved in the pathogenesis of this condition.10 This condition develops from isolated trabeculodysgenesis, commonly presentswith epiphora, photophobia and blepharospasm, and can affect one or both eyes.11 The patients with PCG in our cohort presented with classical signs ofbuphthalmos, Haab's striae, raised IOP and optic disc cupping. This evidence concerns the gene LTBP2 and Epiphora.
