Eur J Ophthalmol. Corneal collagen cross-linking slows or halts the progression of keratoconus. Some risk factors for this disease are clearly demonstrated in literature such as childhood eye rubbing and positive family history of the disease, others are still debated. Triggering factors are sources of reactive oxidative stress; among them, mechanical trauma (vigorous eye rubbing, poorly fit contact lenses), exposure to ultraviolet light, and atopy/allergies [1, 7, 8].

What are the risk factors for developing keratoconus? The objective of the study was to estimate the prevalence of well-established risk factors for keratoconus (family history and eye rubbing, certain ocular and systemic diseases)16 among patients attending Ibn-Alhaitham teaching eye hospital, Baghdad (Iraq) and to assess the role of a range of putative (risk/protective) factors. See additional information. 4 In fact, keratoconus progression typically arrests during the third or fourth decade of life. 2015;2015:119. Keratoconus generally begins at puberty and progresses into the mid-30s. Older subjects with keratoconus should be monitored for progression, particularly with respect to possible corneal collagen cross-linking or astigmatic correction in cataract surgery. Contact Us Myth 3: If the patient has lost vision and is contact lens intolerant, it is time for a transplant Cross-linking often reshapes the cornea enough to make a contact lens easier to fit and more comfortable. This discrepancy in results may stem from environmental differences, such as high levels of dust in some climates leading to a higher prevalence of eye rubbing among patients and controls, thus concealing a possible association. Keratoconus can recur in the graft (4), so it makes me more comfortable to know the host cornea rim has been treated and is more stable. Exclusion criteria for both cases and controls include at least one of: (1) inability to accurately recall events related to questionnaire of the study, (2) mental retardation, (3) presence of severe ocular surface disease or corneal pathology that might interfere with accurate diagnosis of KC. These results support the evidence for multifactorial etiology, the most important factor being hereditary predisposition.Keywords: keratoconus, corneal ectasia, childhood eye rubbing, parental consanguinity. It is not unusual that certain treatment options, pharmaceutical or surgical, might initiate or accelerate the progression of KC. 2000;84(8):834836.

Terms and Conditions, Cite this article. The changes are independent of normal age-related changes and appear to be slower in cases with steeper and thinner corneas. However, we will continue to see advanced keratoconus patients in our practices, and I believe that most of these patients provided they do not have central scarringwould benefit from cross-linking before considering a transplant, regardless of their age, visual acuity, or contact lens tolerance. Before Terms & Conditions Learn about our keratoconus research Eye rubbing was associated with a more than 4-fold increase in risk of KC, while positive family history of KC and parental consanguinity resulted in approximately 25-fold and 3-fold increased risk of the disease, respectively. Purpose: To investigate the outcomes of accelerated (A-CXL) and iontophoresis (I-CXL) corneal crosslinking in a large retrospective cohort with progressive keratoconus.

The lifetime economic burden of keratoconus: a decision analysis using a Markov model. 19. This study aimed to analyze associations between several hereditary and environmental predictors and the development of keratoconus.Patients and Methods: This was a retrospective matched pair case-control study. In another teenage progressive keratoconus patient I treated, the Pentacam difference map (see Figure 2) confirms that the treatment was a success. Likewise, other presumed predictors (ocular trauma, childhood obesity and exposure to smoking) were not associated with the risk of developing KC in our study, in agreement with the two case-control studies by Gordon-Shaag et al.21,23 Spoerl et al found a negative association between smoking and KC, and hypothesized that toxic by-products might induce cross linking of the stromal corneal collagen.27 However, unlike our study they analyzed smoking after the development of the disease which might explain the difference in results.
