PURPOSE Recruitment of lymphocytes into the retina and to the vitreous during the development of experimental autoimmune uveitis (EAU) is governed by factors such as the state of activation of inflammatory cells and the repertoire of adhesion molecules expressed by the local vascular endothelia. alpha4 Integrins and their receptors play an important role(More)
PURPOSE To identify the proteins in the corneal droplets of climatic droplet keratopathy (CDK), a disease that results in the formation of droplets on the cornea. Progressive accumulation of droplets in CDK leads to visual loss. METHODS Proteomic mass spectrometry of the CDK specimens was performed after fractionation of proteins in 4% to 20%(More)
PURPOSE To determine levels of Peptidyl arginine deiminase 2 (PAD2) and its product protein-bound citrulline in cadaver eyes that suffered from normal tension glaucoma (NTG) compared to primary open angle glaucoma (POAG), and controls. METHODS Western analysis, ELISA, and immunohistochemical analysis were performed with human tissues. RESULTS We report(More)
Climatic droplet keratopathy (CDK) is a degenerative corneal disease of unknown etiology. We described CDK for the first time in Latin America in the Argentinean Patagonia (El Cuy). A deeper knowledge of CDK pathogenic mechanisms will provide new therapeutic strategies. For that reason we investigated the prevalence of CDK in El Cuy and its existence in(More)
PURPOSE Climatic droplet keratopathy (CDK) is a degenerative disease of the cornea with possible involvement from matrix metalloproteinases (MMPs). Therefore, the authors investigated histologic distribution, levels, and molecular forms of MMP-2 and MMP-9, as well as tear fluid levels of MMPs and cytokines in CDK patients. They additionally examined(More)
BACKGROUND Conjunctival amyloidosis is a very rare condition, generally unilateral, and presents mostly as an isolated condition without systemic compromise. Our purpose is to present a new case of systemic amyloidosis with a bilateral conjunctival involvement. CASE PRESENTATION A 66-years-old caucasian female complaining of conjunctival hemorrhage and(More)
BACKGROUND The efficacy and safety of ketotifen eye drop treatment in allergic conjunctivitis (AC) management is perfectly known by several studies, but the mechanism of action at the biochemical levels is poorly understood so we decided to perform an open, uncontrolled study in order to investigate the effect of the topical administration of ketotifen(More)
PURPOSE To determine whether the incidence of and susceptibility to climatic droplet keratopathy (CDK), an acquired, often bilateral degenerative corneal disease, is influenced by the genetic background of the individuals who exhibit the disorder. METHODS To determine whether the disease expression was influenced by the genetic ancestry of CDK cases in(More)
BACKGROUND Although frequently underdiagnosed, squamous cell carcinoma is the most commonly observed malignancy of the conjunctiva. Multiple different treatments have been proposed to date. The purpose of this paper is to report our experience in the treatment of In situ carcinoma of the conjunctiva by surgical excision associated with cryotherapy. (More)
PURPOSE To present a case of a complicated posterior melanocytoma that was successfully treated with intravitreal bevacizumab. CASE REPORT A 50-year-old Caucasian man was referred with sudden-onset metamorphopsia and decreased vision in his right eye over the course of the last 2 months. His best-corrected visual acuity was 20/80 and poorer than Jaeger 14(More)
