Iris hypoplasia with glaucoma, also known as Iris hypoplasia and glaucoma or simply IHG is a very rare genetic disorder which is characterized by a combination of an underdeveloped of the iris and glaucoma. It has been described in three families; two from Russia [1] and one from London, United Kingdom It was mapped to a duplication of the q25 region of chromosome 6 through the London family.[2] Tooth agenesis can sometimes be associated with this disorder.[3]
