Keratoconus

Outcomes after corneal crosslinking treatment in paediatric patients with keratoconus

“…The association between thyroid dysfunction and keratoconus was rst reported in the 1930s. Appelbaum reported a series of keratoconus patients with severe symptoms of hypothyroidism [25]. Later, King reported a case of keratoconus following thyroidectomy.…”

Impact of Hypothyroidism on Tomography and Biomechanics in Keratoconus – Cross-Sectional and Longitudinal Assessment within the Homburg Keratoconus Center at the Time of Inclusion and after 1 Year

“…On the contrary, previous studies about the prevalence of hypothyroidism in KC patients seem to indicate that the prevalence of KC is higher in patients with hypothyroidism than in a healthy population. Indeed, Appelbaum reported in 1936 that KC patients often show unusual signs of hypothyroidism [3]. El-Massary et al suggested a higher prevalence of thyroid gland dysfunction among KC patients compared to healthy controls (5.35 and 1.1 %, respectively).…”

Association Between Keratoconus and Thyroid Gland Dysfunction: A Cross-Sectional Case–Control Study

“…Thus, our results are consistent with previous reports showing a positive association between keratoconus and thyroid gland dysfunction. [6][7][8][9]13,14 For example, Kahán et al 8 reported that, in 50 patients with keratoconus, 27 had euthyrosis, 6 had hyperthyrosis, and 17 had hypothyrosis in terms of their blood serum thyroxine level. Moreover, the tear thyroxine levels of patients with keratoconus were found to be 2 to 50 times higher than those of patients without ocular diseases and levels were higher during the progression of keratoconus and declined once cornea curvature fulfilled a new steady value.…”

“…Previous studies investigated the association between thyroid gland dysfunction and keratoconus, suggesting a positive correlation. [6][7][8][9] In 1936, Appelbaum 6 described a series of patients with keratoconus in whom there was a high prevalence of hypothyroidism symptoms, whereas King 7 reported keratoconus after thyroidectomy. In 1990, Kahán et al 8 reported a possible role of tear fluid thyroxine (T4) in keratoconus development.…”
