Learning what comes next in the process is most important. Modern corneal tomography, including both anterior and posterior elevation and pachymetric data can be used to screen for ectatic progression, be employed to Logik also showed better accuracy for grading keratoconus stages with an average accuracy of 99.9% versus (98.2%, 94.7%) with BAD_D and TKC respectively. If your keratoconus is progressing, corneal collagen cross-linking might be indicated to slow or stop the progression. 2018;34(3):177–180. lowed for progression. Methods In this retrospective cohort study (2010–2016), 265 eyes of 165 patients diagnosed with keratoconus underwent two Scheimpflug measurements (Pentacam) that took place 1 year apart ±3 months. Scleral contact lenses give the most consistently reliable results with excellent vision and comfort. Introduction Keratoconus is a clinical term used to describe a condition in which the cornea assumes a conical shape as a result of non-inflammatory thinning and protrusion. Chatzis N, Hafezi F. Progression of keratoconus and efficacy of pediatric [corrected] corneal collagen cross-linking in children and adolescents. Aim: To define variables for the evaluation of keratoconus progression and to determine cut-off values. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape, causing distorted vision. Over the past 5-10 years, corneal collagen crosslinking has become a promising treatment for slowing or stopping the progression of keratoconus, although most of the studies have been in adults. Keratoconus rarely leads to complete blindness, although the progression of the disorder can't be undone. September 1, 2015 September 1, 2015 Curtis Lipsey Keratoconus Keratoconus. Glasses may be an option in the early stages of keratoconus; however, you should be closely monitored. There are several tests that will be preformed on you to determine the condition of your cornea. Treatments for keratoconus, such as specialized contact lenses, Intacs, collagen cross-linking, and corneal transplants, can all be beneficial. Keratoconus is an ectatic corneal disorder characterized by progressive corneal thinning that generates a corneal protrusion, irregular astigmatism, and decreased vision.1, 2 The corneal protrusion, which has a conical shape, is generated by stromal tissue degeneration, leading to a mechanical weakening of the corneal structure.2, 3 Keratoconus typically affects both eyes. Keywords: keratoconus; progression; videokeratography 1. Keratoconus can be managed to keep vision stable. Patients only undergo this operation when they have advanced keratoconus and are suffering severe visual and/or structural problems. This happens in about 20% of people with keratoconus. J Refract Surg . Therefore, corneal thinning is often measured for monitoring progression and staging of the disease. At Total Eye Care, our keratoconus experts find that over 90% of patients their patients are successfully treated with contact lenses. Ultrasound pachymetry can also be used to measure the thinnest zone on the cornea. It is the most common primary ectasia, and is characterized by corneal steepening, visual distortion, apical corneal thinning, and central corneal scarring [1, 2, 3].Corneal thinning typically occurs inferotemporal as well as central, although superior thinning has also been described []. The multivariate model confirmed that the progression steepening of the maximum keratometry while waiting for treatment was associated with age (P = .028). The calculation of the κ value was based on the difference between the extent of agreement with the standard observed compared to the extent of agreement expected due to chance alone. Of the parameters used to document keratoconus progression, the posterior surface is the least affected by outside forces. 2018;34(3):177-180. Background/aims To determine if significant progression of disease occurs in older, non-contact lens wearing, subjects with keratoconus and to identify potential predictive factors. What is Keratoconus? The specific underlying cause is not fully understood and most likely the condition results from the interaction of multiple factors including genetic and environmental ones. If your condition progresses to an advanced stage, you may need a cornea transplant. When calculating the κ value, progression to keratoplasty, a previously used unambiguous criterion of keratoconus progression, was used as a standard [8, 9]. Methods: In this retrospective cohort study (2010-2016), 265 eyes of 165 patients diagnosed with keratoconus underwent two Scheimpflug measurements (Pentacam) that took place 1 year apart ±3 months. To use these parameters to determine progression, we first had to determine the measurement noise levels associated with each parameter. Performing laser refractive surgery on an individual who is in the early stages of keratoconus—or any other corneal thinning disorder—is a bad idea; the consequences of missing this disease can be devastating for both the patient and the surgeon. Since 1999 Dr. Brian Boxer Wachler, expert in Keratoconus Treatments has been treating patients from all over the world every week. Pro-gression of keratoconus occurred in 52 (88%) of the 59 eyes investigated. The estimated preva-lence of keratoconus is about 50e230/100,000 in the general population (Rabinowitz, 1998). Each eye may be affected differently. Aim To define variables for the evaluation of keratoconus progression and to determine cut-off values. Keratoconus: Time to Rewrite the Textbooks Recent work is showing that many patients with keratoconus or post-LASIK keratoectasia are contributing to their own condition. New algorithms using computerized videokeratography have been devised which now allow the detection of forme fruste, subclinical, or suspected keratoconus.
