OBJECTIVES To provide comprehensive trial methods and baseline data for the Steroids for Corneal Ulcers Trial and to present epidemiological characteristics such as risk factors, causative organisms, and ulcer severity. METHODS Baseline data from a 1:1 randomized, placebo-controlled, double-masked clinical trial comparing prednisolone phosphate, 1%, with placebo as adjunctive therapy for the ...
PURPOSE To help further define the possible role of vascular endothelial growth factor (VEGF) in the pathogenesis of corneal neovascularization, the expression of VEGF and of its receptors Flt-1 and Flk-1 was investigated in various inflammatory corneal diseases. METHODS Polyclonal antibodies to VEGF and its receptors were used for immunohistochemical staining of frozen sections of 38 human c...
OBJECTIVES To retrospectively evaluate the complications, graft clarity, and outcomes associated with the use of commercially available porcine urinary bladder submucosa (ACell Vet(™) ) alone for corneal reconstruction in dogs and cats. PROCEDURES Dogs or cats receiving an ACell Vet(™) graft for corneal reconstruction due to severe ulcerative keratitis or after a keratectomy to remove a corne...

Introduction : Horizontal corneal diameter is one of the diagnostic factors in some ophthalmic diseases. At present American Newborn horizontal corneal diameter is considered as our normal value in Iranian ones, while it may be quite different in Iranian newborns. Early diagnosis is critical in some ophthalmic diseases such as congenital glaucoma and awareness of normal corneal diameter is es...
PURPOSE To analyze the amounts and distributions of nonsulfated and sulfated keratan sulfate (KS) and chondroitin/dermatan sulfate (CS/DS) disaccharides in the interface wound of human postmortem LASIK corneas in comparison with normal control corneas. METHODS Corneal stromal tissue samples from central and paracentral hypocellular primitive stromal interface scars of human LASIK corneas and ...
THE prime indication for transplanting a graft of the patient's own corneal tissue from one side to the other is the presence of a dense extensive corneal scar on a potentially seeing eye, while the other side has a clear cornea in an eye with an intractable and blinding lesion in the intra-ocular media or fundus. Such cases are not commonly seen, but have been reported mainly because the best ...
