PURPOSE To evaluate the efficacy and the safety of a surgical technique in which classic trabeculectomy ab externo is performed with a double application of low-dose mitomycin C (MMC) in uncontrolled open-angle glaucoma (OAG) patients. METHOD A consecutive series of 43 white patients (43 eyes) with uncontrolled primary OAG underwent trabeculectomy surgery. A double application of MMC (0.1%) w...

CYNTHIA M AT TOX, MD Up until about 4 years ago, I always performed my combined phacoemulsification/trabeculectomy procedures with a fornix-based conjunctival flap and my straight trabeculectomies with a limbus-based flap. I liked the closure I used for each. Fellows would ask me, “Why the difference?” I was not entirely satisfied with the IOP-lowering effect of my combined procedures, but I wa...

PURPOSE ExPress devices are available as P50 and P200 models, the numbers related to their luminal diameters in μm. We compared their Poiseuille's Law-based theoretical resistance values with experimental values and correlated these with their luminal dimensions derived from electron microscopy. METHODS Scanning electron microscopy was performed on P50 and P200 devices. Bench-top flow studies...

PURPOSE To compare the surgical outcomes of the two different methods used for Ahmed Glaucoma Valve (AGV) implantation between the donor scleral graft method and the partial-thickness scleral flap method. METHODS We retrospectively reviewed medical records of 28 eyes of 26 patients diagnosed as neovascular glaucoma followed by AGV implantation. Based on the surgical method, the included eyes ...

PURPOSE To compare two surgical approaches for treating encapsulated blebs after trabeculectomy with mitomycin C, in terms of the development of intraocular pressure and progression of glaucoma in a long-term follow up: 1. bleb needling alone vs. 2. a combined approach of needling with additional transconjunctival scleral flap sutures, to prevent early ocular hypotony. METHODS Forty-six patie...

PURPOSE To report the outcomes of surgical refixation of posteriorly dislocated intraocular lens (IOL) using scleral-tuck method, and to compare the "scleral groove" and the "scleral flap" techniques used. STUDY DESIGN Single-center, retrospective, interventional, comparative study. METHODS Medical records of patients undergoing closed globe scleral refixation of posteriorly dislocated post...

CASE REPORT A 75-year-old man presents for routine follow-up examination 6 years after uncomplicated primary trabeculectomy with a 2minute intraoperative application of mitomycin C (MMC, 0.4mm/ mL). Although progression had occurred when the intraocular pressure (IOP) was in the mid teens, the visual fields have remained stable since filtration surgery was performed. The IOP is 8mm Hg and a lar...
