Godefrooij DA, de Wit GA, Uiterwaal CS, Imhof SM, Wisse RPL. In the current study, although low SES was more prevalent among controls, this difference was not statistically significant and univariable analysis showed no significant association with KC. It is known that the exact etiology of KC remains unclear. 1 Age-related differences in human corneal biomechanical properties have previously been reported, 1011 and it has been proposed that the resistance to keratoconus progression observed with aging may be due to physiological collagen crosslinking that is similar to the age-related Rabinowitz YS, Galvis V, Tello A, Rueda D, Garca JD. Corneal thinning; Ectasia display indices; Keratoconus; Middle age; Posterior corneal steepening. In many cases, its not clear why keratoconus develops.

In most cases, it develops for no apparent reason. This treatment limits the progression of keratoconus. 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. Records from 33 males and 50 females (female to male ratio 1.52:1) were included. Cases of keratoconus (KC) were diagnosed based on both clinical and tomographic findings in accordance with the global consensus of KC and ectatic diseases definition.16 To maximize the sample size and range, all keratoconic patients attending the hospital during this period were eligible. Also, hes 47; waiting several more years will not likely produce signs of keratoconus, as the onset of keratoconus rarely begins after age 30. In a United Kingdom-based study on 18 pairs of twins, Tuft et al concluded that KC was more concordant among monozygotic than dizygotic twins.24 However, none of the cases in the present study sample was a twin.
