Slowly progressive thinning of the cornea causes a cone-shaped bulge to develop towards the center of the cornea in the areas of greatest thinning. However, there are very good reasons to consider cross-linking instead of or prior to keratoplasty, even in cases with more advanced disease. 4 In fact, keratoconus progression typically arrests during the third or fourth decade of life. Conclusions This study confirms that keratoconus may continue to progress beyond age 30. His uncorrected vision was 20/30 and his best corrected vision was 20/20-. I performed cross-linking and, by the three-month visit, his Kmax had flattened by 1.1 D, improving the uncorrected vision to 20/30-2 and best-spectacle-corrected vision to 20/30. Visual acuity, manifest refraction, topography, specular . On multivariable analysis, eye rubbing (odds ratio: 4.93; P < 0.01), family history of keratoconus (odds ratio: 25.52; P < 0.01) and parental consanguinity (odds ratio: 2.89; P = 0.02), again, emerged as significant risk factors for disease development.Conclusion: Family history of keratoconus, eye rubbing, and parental consanguinity were significant risk factors for keratoconus development.

Jon Greenaway Correspondence to Eye Contact Lens. Myth 1: Older patients dont progress It is a commonly held belief that eyes with keratoconus will eventually undergo natural, age-related cross-linking and stop progressing by age 30 or 40. I have countless patients who have had dramatic visual improvement after cross-linking. We thank head of refractive surgery department at Ibn-Alhaitham eye teaching for his general support, and department staff for assisting us in performing the required clinical tests for this study. These included parental consanguinity, low SES, obesity, ocular trauma, pre-diagnosis contact lens wear, and exposure to sunlight and to smoking.

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. 13. For example, using logistic regression analysis, Bawazeer et al concluded that KC was not associated with atopy, but with eye rubbing so that atopy may be indirectly associated with KC due to the itching that it induces.20,22. 1. Najmi H, et al. Regardless of KC treatment approaches, the majority of eyes with KC present limited or no progression after the age of 30 due to natural cross-linking-like alterations of the cornea by sunlight. Accessed August 6, 2021. (2018). It has been suggested that epithelial microtrauma from rubbing results in cytokines release and keratocytes apoptosis.20, It is of particular interest that three cases in our sample were derived from the same family (two brothers and one sister), with only one male having a history of childhood eye rubbing so several other factors might come into play.
