Congenital iris ectropion associated with juvenile glaucoma.

Congenital iris ectropion is an uncommon malformation of the anterior segment of the eye. The authors describe a case of bilateral congenital iris ectropion associated with juvenile glaucoma in an otherwise healthy 9-year-old girl. Intra-ocular pressure (IOP) measured by Goldmann applanation tonometry was 40 mmHg in the right eye and 32 mmHg in the left eye. Despite maximum IOP lowering therapy, the desired IOP levels needed to prevent further progression of the glaucoma could not be achieved. Visual field testing and confocal scanning laser tomography showed glaucomatous neuropathy. Trabeculectomy with antimetabolites (mitomycin C 0.2 mg/ml) was performed in both eyes and IOP was normalized without IOP lowering medications during a follow-up of 4 years. The authors point out the importance of recognizing congenital iris ectropion early to prevent blindness in young patients and improve their prognosis.
