Diurnal variation of CH was not detectable in healthy Asian eyes. The diurnal fluctuation of IOP appears not to be associated with CH. However, CRF was increased a few minutes after sleeping, a change that was correlated to the changes of IOPg.

High myopic eyes showed decreased CH, but not corneal resistance factor, which indicates that some aspects of corneal biomechanical properties may be altered in high myopic eye of anisometropia. It is also suggested that anisometropic eyes with different refractive errors do not share the same biomechanical properties, which may impact IOP measurement.

Punctal occlusion with collagen plugs in dry eye patients leads to the relief of subjective symptoms and the improvement of objective signs. The effectiveness of occluding the upper or lower punctum is similar. The LTMH is a valid indicator of the success of punctal occlusion.
