This study was a retrospective study on corneal ulcer of one year period in Hospital Ipoh. A total of 28 cases were studied. Among the risk factors identified were foreign body on cornea, trauma, contact lens, vernal keratoconjunctivitis and surgical complication. The nature of this disease which was severe and slow healing caused prolonged hospital admission. Identification of causative microo...

PURPOSE Recent studies suggest that natural killer (NK) cells exert effector/regulatory properties on both innate and adaptive responses via release of different cytokines. While some information indicates NK cells in allergic asthma and atopic dermatitis, no data are available for allergic conjunctivitis. The aim of this study was to evaluate NK in the blood and the conjunctiva of patients wit...

PURPOSE Previously, we have reported that local excision and immunosuppressive treatment are useful in treating patients with very severe vernal keratoconjunctivitis (VKC). METHODS We measured serum levels of immunoglobulins, cytokines, and interleukin-2 receptors (IL-2R) and the concentration of IL-4 in tears of 10 patients with severe VKC, and made a comparison with data from 10 healthy con...

BACKGROUND/AIMS Chemokines are small peptides which are potent activators and chemoattractants for leucocyte subpopulations. Their action is mediated by a family of seven transmembrane spanning G-protein coupled receptors. The aims of this study were to examine the expression of the chemokine receptors CCR1, CCR3, CCR5, CXCR3, and CXCR4 in the conjunctiva of patients with vernal keratoconjuncti...

Vernal keratoconjunctivitis (VKC) is a severe ocular disease with immediate and delayed hypersensitivity reactions which can produce loss of visual acuity and blindness. In its physiopathology a Th1 and Th2 response is present and the therapeutic approach is very difficult because the use of local immunosuppressive therapy such as topical corticosteroids for a long time could produce severe adv...

Background: Vernal keratoconjunctivitis (VKC) is a bilateral ocular allergic disease mediated by hypersensitivity reactions. VKC events occur in boys the first decade of life and continue until puberty. Early identification effective treatment are essential because condition recurrent potentially burdensome to patient's quality life. This case report examines diagnosis, management, therapy opti...

PURPOSE To evaluate the role of nerve growth factor (NGF) in remodeling processes of vernal keratoconjunctivitis (VKC). VKC is a chronic inflammatory disorder of the conjunctiva and is characterized by marked tissue remodeling. NGF, a pleiotrophic factor with documented profibrogenic activities, is produced by inflammatory and structural cells populating the VKC conjunctiva and is increased in ...
