Detection of Keratoconus With a New Biomechanical Index.
PURPOSE To evaluate the ability of a new combined biomechanical index called the Corvis Biomechanical Index (CBI) based on corneal thickness profile and deformation parameters to separate normal from keratoconic patients. METHODS Six hundred fifty-eight patients (329 eyes in each database) were included in this multicenter retrospective study. Patients from two clinics located on different co...
متن کاملKeratoconus.
Keratoconus is a slowly progressive, non-inflammatory disorder of the eye characterized by thinning and protrusion of the cornea. Typically diagnosed in the patient's adolescent years, keratoconus may lead to substantial distortion of vision primarily from irregular astigmatism and myopia, and secondarily from corneal scarring. The classic histopathologic features include breaks in Bowman's lay...
متن کاملKeratoconus.
Not too long ago, the options for treatment of keratoconus were limited to contact lens wear or penetrating keratoplasty. Times have changed, which is reflected in 4 articles in this issue that have some bearing on current investigation and treatment options. One hundred fifty years ago, Dr. John Nottingham provided the first detailed description of keratoconus, with further observations by his...
متن کاملKeratoconus.
Keratoconus is a bilateral noninflammatory corneal ectasia with an incidence of approximately 1 per 2,000 in the general population. It has well-described clinical signs, but early forms of the disease may go undetected unless the anterior corneal topography is studied. Early disease is now best detected with videokeratography. Classic histopathologic features include stromal thinning, iron dep...
متن کاملKeratoconus diagnosis using Corvis ST measured biomechanical parameters
PURPOSE To assess the diagnostic power of the Corneal Visualization Scheimpflug Technology (Corvis ST) provided corneal biomechanical parameters in keratoconic corneas. METHODS The following biomechanical parameters of 48 keratoconic eyes were compared with the corresponding ones in 50 normal eyes: time of the first applanation and time from start to the second applanation [applanation-1 time...
