PURPOSE To develop ex vivo organ culture models of human corneal scarring suitable for pharmacological testing and the study of the molecular mechanisms leading to corneal haze after laser surgery or wounding. METHODS Corneas from human donors were cultured ex vivo for 30 days, either at the air-liquid interface (AL) or immersed (IM) in the culture(More)
BACKGROUND As bacterial adhesion to contact lenses may contribute to the pathogenesis of keratitis, the aim of our study was to investigate in vitro adhesion of clinically relevant bacteria to conventional hydrogel (standard HEMA) and silicone-hydrogel contact lenses using a bioluminescent ATP assay. METHODS Four types of unworn contact lenses (Etafilcon(More)
We recently showed that the highly organized architecture of the corneal stroma could be reproduced using scaffolds consisting of orthogonally aligned multilayers of collagen fibrils prepared using a high magnetic field. Here we show that such scaffolds permit the reconstruction in vitro of human hemi-corneas (stroma + epithelium), using primary human(More)
Skin and cornea both feature an epithelium firmly anchored to its underlying connective compartment: dermis for skin and stroma for cornea. A breakthrough in tissue engineering occurred in 1975 when skin stem cells were successfully amplified in culture by Rheinwald and Green. Since 1981, they are used in the clinical arena as cultured epidermal autografts(More)
INTRODUCTION Intravitreal implantation of Ozurdex(®) (Allergan Inc., Irvine, CA, USA) is being used widely for the treatment of macular edema secondary to retinal vein occlusion and in the setting of non-infectious posterior uveitis. We describe a complication little reported in the literature until now: migration of the dexamethasone implant into the(More)
PURPOSE Conjunctival epidermoid carcinoma (CEC) is a rare tumor affecting mainly the perilimbal region of the bulbar conjunctiva. We report an atypical presentation of a CEC mimicking a Mooren pseudo-ulcer. CASE REPORT A 78-year-old man presented a limbic corneal ulcer of the left eye that had appeared a few months before. Ophthalmologic examination(More)
INTRODUCTION Syphilis, caused by Treponema pallidum agent, results in polymorphic and non-specific ocular manifestations. Early diagnosis and institution of individualized treatment play a large role in the prognosis. The increase in syphilis over the past several years requires the ophthalmologist to consider this diagnosis in the setting of any(More)
INTRODUCTION Retrospective study analyzing clinical characteristics and treatment of children affected by Leber-Coats' disease. METHOD Children with Leber-Coats' disease seen in Edouard-Herriot Hospital, Lyon, between January 2004 and September 2013 were included. The following clinical characteristics were reported: sex, age at diagnosis, presenting(More)
