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...

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...

BACKGROUND Transscleral tunnel incisions are commonly made to avoid postoperative leakage in small gauge sutureless vitrectomy. We present an unreported intraoperative complication, tunnel incision related arterial hemorrhage from sclerotomy, in 23-gauge (23G) vitrectomy. CASE PRESENTATION Two cases of intraocular arterial hemorrhage from superonasal sclerotomy were observed at the beginning ...

Aim: The aim of this study is to introduced the efficacy, longevity and safety of this new ‘T’shaped limbal based sclera flap with fornix based conjunctival flap trabeculectomy leading to better result like controlling intra ocular pressure satisfactory ,and no shallow anterior chamber after the surgery. Method: As it is a clinical research which was done on 26 patients and all the patient went...

Purpose: To investigate the current status and demographics of patients who underwent mitomycin C-augmented trabeculectomy (MMC-trabeculectomy) in Japan using data from the Collaborative Bleb-related Infection Incidence and Treatment Study. Subjects and Methods: Out of 1,249 patients (1,249 eyes), we selected patients who underwent trabeculectomy alone or phacotrabeculectomy using MMC. Age at t...

PURPOSE To evaluate the in vivo changes in the Schlemm's canal (SC) in patients with primary angle-closure glaucoma (PACG) after trabeculectomy using spectral-domain optical coherence tomography (SD-OCT). METHODS Forty eyes of 40 patients with PACG who underwent trabeculectomy were included. All participants underwent SD-OCT. The diameter and area of SC were examined and measured before and w...
