BACKGROUND Surgical treatment of pressure ulcers is challenging for high recurrence rates. Deepithelialized flaps have been used previously with the aim to eliminate shearing forces and the cone of pressure (COP) effect. The goal of this study is to adopt a standardized protocol and evaluate if 2 different flap techniques affect outcomes. METHODS The novel COP flap is illustrated. Twenty pati...

BACKGROUND To report a case of impending extrusion of Ex-PRESS shunt treated by shunt-position adjustment. CASE PRESENTATION A 56-year-old Asian woman presented with impending extrusion and malposition of Ex-PRESS shunt in her left eye. The bleb of the left eye was shallow and diffuse. In the past, the patient was treated by Ex-PRESS shunt implantation under the scleral flap in both eyes. The...

Abstract Purpose In an era when trabeculectomy surgeries in the United States are on decline, ophthalmology residents may have limited opportunities to practice surgical techniques critical success. However, key steps of surgery can be introduced a wet laboratory using simple model based food items. Methods A fresh lime and chicken parts with skin, purchased from grocery store, were utilized su...

Cutaneous leiomyosarcoma is a rare neoplasia, and its periorbital presentation is rather uncommon. We present a case of a male patient who was surgically treated, with the reconstruction performed with a frontal myocutaneous flap. The patient has been followed up for one year with adequate oncologic control and good aesthetic outcome.

We read with interest the article by Sheybani et al. demonstrating the assessment of fluid dynamics and flow control between the XEN 45 microfistula implant (AqueSys, Aliso Viejo, CA, USA), EX-PRESS implant (Alcon Laboratories, Inc., Fort Worth, TX, USA), and silicone tubing from a Baerveldt implant (Abbott Medical Optics, Abbott Park, IL, USA). The authors demonstrated that the Hagen-Poiseuill...

Glaucoma is the second leading cause of blindness with ∼70 million people worldwide who are blind from this disease. The currently practiced trabeculectomy surgery, the gold standard treatment used to stop the progression of vision loss, is rather draconian, traumatic to the patient and requires much surgical skill to perform. This article summarizes the more than 10-year development path of a ...

This study sought to describe a glaucoma patient with interface fluid syndrome (IFS) induced by uncontrolled intraocular pressure (IOP) without triggering factors after laser in situ keratomileusis (LASIK). Case report and review of the literature. A 23-year-old man with open-angle glaucoma underwent bilateral LASIK for myopia in 2009. Two years later, the patient reported sudden vision loss. T...

OBJECTIVE To determine whether the timing of cataract surgery after trabeculectomy has an effect on trabeculectomy function in terms of intraocular pressure control. METHODS This was a cohort study nested within a randomized clinical trial. There were 235 participants with glaucoma who had a single previous trabeculectomy augmented with either intraoperative 5-fluorouracil or placebo. Catarac...
