background/objective: hyperphosphatemia is the consequence of end stage renal failure. inadequate control of serum phosphorus results in elevated ca × p product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  in this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis pat...

a 53 year-old woman presented with corneal edema 25 years after uneventful penetrating keratoplasty for keratoconus. she was initially misdiagnosed with acute endothelial rejection; however by observation of descemet’s membrane detachment, a diagnosis of late onset corneal hydrops following corneal transplantation was made. this is a rare complication which may occur many years after penetratin...

background: the aim was to compare three different methods (direct examination, culture and pcr meth­ods) for the diagnosis of acanthamoeba keratitis (ak) in corneal scrapes. methods: twenty eight corneal scrapes and contact lenses were collected from keratitis patients and re­ferred to the de­partment of medical parasitology and mycology, school of public health, tehran univer­sity of medical ...

background and objective: evaluation of the results, safety, and stability of ferrara intracorneal ring segment (ficrs) implantation for keratoconus correction (age range was 24.39±8.32 years).   materials and methods: in this clinical trial study, 64 eyes of 57 patients with keratoconus and clear cornea that had ficrs implantation were studied. uncorrected visual acuity (ucva), best-spectacle ...

purpose: to evaluate the adverse effects of intravitreal injection of sterile chloramphenicol eye drops on corneal endothelial cells of donated corneas. methods: 100 donor corneas were enrolled in the study. one eye of each donor underwent intravitreal injection of sterile chloramphenicol eye drops following vitreous tap and the fellow eyes were served as controls. after corneo-scleral excision...

corneal transplantation is the most common and successful form of solid organ transplantation with a 2-year survival rate of over 90% in low risk cases. this high success rate may be due to the immune privileged status of the cornea, acaid (anterior chamber associated immune deviation) induction phenomena and secretion of inhibitory molecules by corneal cells such as il1-ra, il-1a and fas ligan...

the objectives of this study were to define the clinical risk factors, microbiological spectrum, and visual outcome of bacterial keratitis at shahid sadoughi hospital (yazd, iran). a crosssectional prospective study, identified 80 cases of microbial keratitis from march 1999 to march 2001. inclusion criteria were presence of corneal stromal infiltrate in slit lamp examination, and microbiologic...

The purpose of this study was to evaluate posterior corneal surface variation after femtosecond laser-assisted keratomileusis in patients with myopia and myopic astigmatism. Patients were evaluated by corneal tomography preoperatively and at 1, 6, and 12 months. We analyzed changes in the posterior corneal curvature, posterior corneal elevation, and anterior chamber depth. Moreover, we explored...
