Glaucoma still represents the most frequent cause of irreversible blindness worldwide. The technological advances lead to innovative surgeries, which are rapidly introduced in clinical practice. New devices to lower intraocular pressure without opening the eye wall, bypassing the trabecular mesh-work, or shunting the aqueous humor to the suprachoroidal space have been approved undergoing clinic...

The implant described in this communication is the direct descendent of a long series of artificial drainage devices which began when Zorab (I9I2) inserted a silk thread through the limbus in order to drain aqueous into the subconjunctival space in cases of glaucoma (see also Mayou, I9I2). Among the more recently described devices are teflon drainage tubes in man (Richards, I955; Epstein, 1959;...

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) gl...

Transient or permanent elevation of intraocular pressure (IOP) is a common complication following vitreoretinal surgery. Usually secondary glaucoma, which develops after scleral buckling procedures, or pars plana vitrectomy for repair of rhegmatogenous retinal detachment, is of multifactorial origin. It is essential, for appropriate management, to detect the cause of outflow obstruction. An exa...

Magnetoelastic resonators made from metal alloy foils are widely used for miniature wireless anti-theft tags and have also been explored for use in various sensing applications. Through annealing within three-dimensional (3D) molds, these foils can be formed into curved structures. Consequently, magnetoelastic materials present an opportunity for the development of a new class of wireless, actu...

There is ambiguity in the literature regarding whether a larger glaucoma drainage device (GDD) achieves a lower long-term intraocular pressure (IOP). There is some evidence on both sides, but overall there seems to be an optimal surface area of approximately 200-250 mm2 beyond which there may be little advantage to increasing the plate size for most patients.

Fungal endophthalmitis is rare but may complicate glaucoma drainage device surgery. Management is challenging as the symptoms and signs may be subtle at initial presentation and the visual prognosis is usually poor due to its resistant nature to treatment. At present there is lesser experience with intravitreal injection of voriconazole as compared to Amphotericin B. We present a case of succes...
