FOR as lonig as operative interferenice is necessary in glaucoma, so I suppose w,ill ophthcaliic surgeons try to devise newx ways of reducinig intra-ocular tension by drainage. Recently the reading of an article (Bick, 1949) oni the use of tantalum metal in drainage of the eve, lhas tenmpted imie to submit thils brief account of some efforts on my own part over the last fewx years to achieve su...

METHODS: A retrospective descriptive study of 10 patients (10 eyes) diagnosed with chronic open-angle glaucoma and high myopia. Patients underwent trabeculectomy with Ologen® implant, without mitomycin, with follow-up at one, three, six and nine months. Follow-up assessment included refraction, intraocular pressure (IOP), presence of complications, and examination of the bleb and implant using ...

Purpose. To report a new technique for anterior placement of tubes for glaucoma drainage devices to reduce the risk of tube erosions. Methods. Retrospective review of select cases of Ahmed Valve surgery combined with the novel method of a limbal-based scleral flap covered by a scleral patch graft to cover the tube at the entrance through the limbus. Intraoperative and postoperative illustration...

Report of a Case. Our patient was born at term with buphthalmos and proptosis of her right eye, accompanied by corneal clouding and increased tearing. She was subsequently noted to have right sphenoid wing dysplasia, multiple cutaneous plexiform neuromas of the right eyelids and face (fifth nerve distribution), right hemispheric dysplastic polymicrogyria, and a seizure disorder. She was diagnos...

IMPORTANCE Control of intraocular pressure after implantation of a glaucoma drainage device (GDD) depends on the porosity of the capsule that forms around the plate of the GDD. OBJECTIVE To compare capsular porosity after insertion of 2 different GDDs using a novel implant and measurement system. DESIGN, SETTING, AND SUBJECTS We performed an experimental interventional study at an eye resea...

The treatment of refractory glaucoma (RG) is challenging. The commonly adopted strategy in RG treatment is a glaucoma drainage device (GDD) implantation, which despite its radical nature may not always provide the desired intraocular pressure (IOP) levels for a long term. This review is based on the scientific literature on Ahmed glaucoma valve (AGV) implantation for refractory glaucoma. The te...
