AIMS This study's objective was to evaluate the tolerance and safety of a new ophthalmic solution based on ReGeneraTing agent (RGTA) technology in a pilot noncontrolled exploration on compassion use for corneal ulcers and severe chronic dystrophies resistant to the usual treatments. RATIONALE RGTAs are large biopolymers engineered to replace heparan(More)
INTRODUCTION Ocular surface squamous neoplasia (OSSN) is the most common conjunctival and limbic malignant tumor that could resemble a pterygium in the early phase of the disease. CASE REPORT We report the case of a woman who presented with a limbic tumor of the left eye that was mistakenly diagnosed as a pterygium. An in vivo confocal microscopy(More)
OBJECTIVE To characterize and understand, at the cellular level, the aqueous humor pathways after filtering surgery, using in vivo confocal microscopy and impression cytology (IC). DESIGN Observational case series. PARTICIPANTS Thirty-two blebs of 29 patients after trabeculectomy were retrospectively evaluated. METHODS In vivo confocal microscopy and(More)
PURPOSE To describe corneal and conjunctival epithelial changes in various ocular surface disorders with a new in vivo confocal microscope (Corneal HRT II module) and to compare these results with those obtained by immunohistology on impression cytology specimens. METHODS In this study, we investigated 36 eyes of 18 patients with ocular surface diseases(More)
PURPOSE To describe the pterygium structure with a high-resolution in vivo confocal microscope and to show the typical components of active pterygium. METHODS In this study, 15 patients with 20 pterygia were examined. None of them had had prior pterygium surgery. Slit lamp examination and in vivo confocal microscopy imaging (Heidelberg Retina Tomograph II(More)
PURPOSE The position and appearance of the upper eyelid crease is one of the challenges in eyelid surgery. The aim of this study was to compare the clinical appearance of the upper eyelid crease with its anatomy, including the position of the levator, the septum, and the orbital fat as determined by Magnetic Resonance Imaging (MRI). MATERIALS AND METHODS(More)
The knowledge of ectopic pregnancies risk factors (intra-uterine device; past history of pelvic inflammatory disease; history of tubal pathology and tubal surgery; positive chlamydiae serology; and smoking), the high sensitivity and specificity of radioimmunological assay of beta-HCG and the availability of high resolution sonography using vaginal probes(More)
INTRODUCTION The Argus II retinal prosthesis is composed of an epiretinal electrode array positioned over the macula and connected to an extrascleral electronics case via a silicone cable, running through a sclerotomy. During implantation, the manufacturer recommends to cover the sclerotomy site with a patch of processed human pericardium to prevent(More)
