Experimental flow studies in glaucoma drainage device development.
AIMS (I) To examine whether small holes produced by 248 nm excimer laser ablation in a polymer substrate could consistently produce a pressure drop in the desired target range (5-15 mm Hg) at physiological aqueous flow rates for use as an internal flow restrictor in a glaucoma drainage device, and (ii) to investigate whether external leakage could be reduced in comparison with conventional tube...
متن کاملDetermination of bleb capsule porosity with an experimental glaucoma drainage device and measurement system.
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...
متن کاملDimensional and Flow Properties of the EX-PRESS Glaucoma Drainage Device
We read with interest the article by Sheybani et al. demonstrating the assessment of fluid dynamics and flow control between the XEN 45 microfistula implant (AqueSys, Aliso Viejo, CA, USA), EX-PRESS implant (Alcon Laboratories, Inc., Fort Worth, TX, USA), and silicone tubing from a Baerveldt implant (Abbott Medical Optics, Abbott Park, IL, USA). The authors demonstrated that the Hagen-Poiseuill...

متن کاملLate onset endophthalmitis associated with unexposed glaucoma valved drainage device.
We report an extremely rare presentation of late-onset endophthalmitis in a young adult patient with an unexposed Ahmed tube implant. The implant was inserted 11 years prior to presentation. There was no history of trauma or any obvious exposure on clinical examination and the tube plate was filled with purulent material. After aqueous and vitreous tap, the patient underwent intracameral, intra...
