A 50 year-old woman with bilateral congenital glaucoma underwent right Ahmed tube drainage to control the intraocular pressure. Examination showed Haab's striae and previous trabeculectomies in both eyes. The left eye also had had cataract surgery with intraocular lens implants. However, the right intraocular pressures was high at 30mmHg despite three different eyedrops (latanoprost, trusopt and timolol).
