Iridogoniodysgenesis: A Challenging Case.

Iridogoniodysgenesis is a rare autosomal dominant disorder affecting anterior segment of the eye. Fifty percent cases of iridogoniodysgenesis have glaucoma, which is particularly difficult to manage. We report here a case of 40 years old man with this rare disorder, presenting to our glaucoma department. It was characterised by iris hypoplasia and juvenile glaucoma. To stop fluctuation in his intraocular pressure (IOP) and to save his vision from glaucomatous damage, our team had to do three different surgical procedures, i.e. trabeculectomy with F5U, diode laser cycloablation and aqueous shunt procedure, over a period of 10 months. This case report discusses management of glaucoma in this particular patient and challenges faced during the treatment. Regular follow-up and timely intervention can save such patients from complete blindness. To authors' knowledge, this is the first reported case of iridogoniodysgenesis in Pakistan.
