Summary The Ahmed Glaucoma Valve is designed to drain aqueous humor from the anterior chamber through a silicone tube and across flow-resistant valve mechanism, and then onto a silicone or polypropylene plate located posterior to the limbus. The incorporation of…
Summary The Baerveldt glaucoma implant continues to play an important role in the management of patients with glaucoma. Careful preoperative planning and meticulous operative technique will help minimize complications. At present the implant is generally recommended for the surgical management…
Summary Results depend on the etiology of the glaucoma and previous ocular history. The Otago Glaucoma Surgery Outcome Study follows surgically treated cases of glaucoma at Dunedin Hospital, New Zealand. Long-term IOP control at 5 years (and 10 years if…
Summary Since publication of the Tube vs. Trabeculectomy Study there has been increased interest in the use of aqueous shunts for the management of glaucoma. Evidence suggests that long-term IOP control after aqueous shunts is determined, not only by the…
Summary The ultimate goal to be wished for with the use of a glaucoma implant is pressure lowering. Most studies reported in the literature, with the use of glaucoma implants, define success as pressures of 21 mmHg or lower. Most severe…
Summary Goniosynechialysis (GSL) is a surgical procedure designed to strip the synechiae from the angle wall and restore the trabecular outflow. The success of the procedure depends not only on the preoperative duration but also the recurrence of the PAS.…
Summary ▪ Although phacotrabeculectomy is the most widely reported combined procedure, nonpenetrating glaucoma surgery (NPGS) combined with phaco appears to be a less invasive approach. ▪ Phacoemulsification offers the advantages associated with small incisions, while NPGS avoids ocular decompression and…
Summary Combined phacoemulsification and glaucoma device implant surgery is a viable alternative in eyes with cataract and refractory glaucoma. Its success rate and complications are similar to those observed with implant surgery alone. This procedure should be considered in selected…
Summary There is no single approach to the patient with coexisting cataract and glaucoma. Each case must be individualized in terms of glaucoma type and severity, rate of progression, response to glaucoma therapy, and degree of cataract. In addition, there…
Summary Cataract surgery may impair the function of the filtering bleb following trabeculectomy even with modern clear cornea phacoemulsification. This fact has an impact on the overall long-term outcome of trabeculectomy when cataract formation is considered a usual long-term complication…
