Determination of Bleb Capsule Porosity With an Experimental Glaucoma Drainage Device and Measurement System

Abstract

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 research facility in a tertiary eye care center. Testing was performed on 22 adult New Zealand white rabbits that received the experimental GDD or an existing GDD. INTERVENTIONS: A new experimental GDD, the Center for Eye Research Australia (CERA) implant, was created using computer-aided design and a 3-dime..
