The corneas of people with glaucoma seem to exhibit different qualities than those who do not suffer from this condition.
A French study determines that corneas of patients with glaucoma are more likely to be less elastic and lose their proper shape than healthy corneas. The researchers assessed the condition of almost 500 eyes with and without glaucoma and found that the eyes of patients with glaucoma tended to have a higher corneal resistance factor (CRF) and lower corneal hysteresis (CH) – both signs of poor corneal biomechanics.
Corneal resistance refers to the flexibility or none flexibility of the cornea – a higher factor means that the cornea is less flexible. I higher factor means that the cornea is less flexible.
Corneal hysteresis refers to the ability of the cells comprising the cornea to to absorb and scatter energy. A lower hysteresis factor means that the cornea is less able to accomplish these tasks – which are important, among other things, for blocking damaging UV radiation and blue light.
