Keratoconus (KC) is a bilateral sight threatening disease that affects the cornea. It consists of gradual steepening central cornea associated with irregular astigmatism and may lead to corneal opacities. In some cases, keratoplasty needed restore vision. Even though it not frequent, recurrence KC in donor tissue has been described, usually bilateral. Recurrence respond problems related graft o...

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...

AIMS A blind, randomised, prospective, bilateral study to investigate the efficacy of riboflavin/ultraviolet A corneal collagen cross-linkage to halt the progression of keratoconus. METHODS 24 patients with early/moderate bilateral keratoconus with recent progression were recruited. One eye was randomly assigned to undergo collagen cross-linkage following epithelial removal with riboflavin 0....

the hyperimmunoglobulin e syndromes (hiess) are very rare immunodeficiency syndromes with multisystem involvement, including immune system, skeleton, connective tissue, and dentition. hies are characterized by the classic triad of high serum levels of immunoglobulin e (ige), recurrent staphylococcal cold skin abscess, and recurrent pneumonia with pneumatocele formation. most cases of hies are s...

Keratoconus has a common association with atopic conditions. Most keratoconus patients rub their eyes excessively. Eye-rubbing is considered the dominant aetiological factor in two-thirds of patients with keratoconus who progress to contact lens wear. A classification of keratoconus based on the dominant aetiological factors is proposed. No significant psychoneurotic factor was found in the ker...
