Surgical treatment for neovascular glaucoma has evolved from cyclodestructive procedures to full-thickness filtration surgery, to trabeculectomy with antifibrosis drugs and glaucoma drainage implant surgery. The choice of a surgical approach may be influenced by several factors, including the stage of the disease. Many surgeons favor drainage implants when the disease is more advanced or when s...

The performance of an innovative pilot-scale subsurface flow compost wetland for the attenuation of zinc in mine drainage was investigated. The particular novelty of the system, which operated under ambient environmental conditions, was the short hydraulic residence time (HRT) of 7.5 – 14.5 hours. Short HRT is crucial because it reduces absolute wetland size and construction cost, which can be ...

OBJECTIVES To report the incidence and identify risk factors of postoperative complications after Baerveldt glaucoma drainage implantation. METHODS A retrospective review of the medical records of all patients at the Bascom Palmer Eye Institute, Miami, Fla, who underwent placement of a Baerveldt glaucoma drainage implant from October 1, 1992, through October 31, 1996, to determine demographic...

Glaucoma drainage implants are frequently used in children with severe forms of glaucoma, and tube extenders are sometimes required to compensate for ocular growth or when the intraocular portion of the tube is thought to be too short. We report 2 cases of spontaneous disconnection of a tube extender, occurring 8 months after insertion in one case and 3 years later in the other. In both cases t...

Minimally invasive glaucoma surgery (MIGS) has been gaining popularity over the last decade. Although there is no strict definition for MIGS, all the new procedures share the common theme of intraocular pressure reduction with minimal tissue destruction, short surgical time, simple instrumentation and fast postoperative recovery. The use of glaucoma drainage implants has long been the tradition...

purpose : glaucoma following penetrating keratoplasty (pk) continues to be a serious problem that may ultimately become sight threatening. knowledge of the risk factors for development of glaucoma following pk, such as preexisting glaucoma, pseudophakia, aphakia, and previous pk, can limit the occurrence and improve the outcome of the keratoplasty. the management of postkeratoplasty (post-pk) g...

Current treatments for glaucoma are not fully satisfactory. This thesis examines the possibility of improving one of those treatments – the use of a drain in the eye. The goal of the thesis is to increase the likelihood that improved treatments for glaucoma become available at an early date by the use of microsystems engineering. Glaucoma is a serious and common disease of the eye, most often c...

A new method was developed for the analysis of fluorescein exchange between the aqueous humor and cornea which enables calculation of the permeability coefficient of the corneal endothelium and the steady-state aqueous-cornea distribution ratio from one experiment. After intravenous fluorescein injection, aqueous and corneal fluorescence was measured at intervals, using an objective fluorophoto...
