Differences in Keratoconus as a Function of Gender


The Ohio State University College of Optometry, Columbus Ohio (B.A.F., K.Z).

PURPOSE: To characterize gender differences in the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study.
DESIGN: Observational, longitudinal study.
METHODS: A total of 1209 subjects at 16 clinics. For eye-specific categorical variables, the number of eyes per subject with the characteristic was counted. For eye-specific continuous variables, the mean of both eyes was calculated. Multivariate linear (for continuous outcomes) and logistic (for categorical outcomes) regression models were created for each baseline characteristic with statistically significant (P </= .05) differences between men and women. Age, race, education, and corneal curvature were covariates.
RESULTS: The women were older, more likely to report a family history of keratoconus, more likely to be nonwhite, and less likely to complete college than men. Vogt's striae and monocular and binocular high-contrast entrance acuity were the only visual characteristics that varied between men and women in the multivariate model. Women were more likely than men to report ocular symptoms of dryness and complaints based upon a composite score of ocular symptoms. Women reported more hours per day of near work and were less likely to report the ability to wear contact lenses for enough hours to permit reading at home in the evening. Women reported more visits to their eye care practitioner during the previous 12 months. NEI-VFQ results revealed differences in self-reported difficulty with distance activities and driving.

CONCLUSIONS: Gender differences exist in patient history, vision, and ocular symptoms in keratoconus patients.

Ho trovato molto interessante questo sito (purtroppo in inglese) SU LE ALTERAZIONI DEI TESSUTI, in particolare in questa pagine

Keratoconus
Researchers in Argentina found that patients with keratoconus were more likely to be deficient in magnesium than controls. (Interestingly, one of the researchers from this study also noticed the links between Mg deficits, keratoconus and Marfan and Down syndromes.)

Patients with keratoconus are about 8 times more likely to have mitral valve prolapse than controls. Patients with mitral valve prolapse are also usually magnesium deficient. Mg is the common link between the two conditions. Keratoconus, like mitral valve prolapse, is a feature found in many connective tissue disorders.

Patients with keratoconus are 5 times more likely than controls to exhibit hypermobility of selected joints. Hypermobility is also closely linked to mitral valve prolapse, too. Like mitral valve prolapse, hypermobility may also result from magnesium deficits. All three conditions are linked to connective tissue disorders.

Keratoconus, mitral valve prolapse, hypermobility and fibromyalgia are all also all linked to hyaluronic acid abnormalities. Hyaluronic acid synthesis is Mg dependent.

IN SOSTANZA QUI ..DICONO UN PO' CIO' KE SOSPETTAVO IO ...

NON SO QUANTO SIA SERIO IL SITO ..PERO' MANNAGGIA!!!!

RAGAZZI CHE NE DITE DI FARE TUTTI L'ESAME PER VALUTARE IL LIVELLO DI MAGNESIO???? (E MAGARI SE POTETE FARLO FARE ANCHE ALLA VS. MAMMA) ...........
