Diurnal variation of corneal epithelium and stroma measured by optical coherence tomography

open access: yesThe Pan-American Journal of Ophthalmology
Purpose: The purpose of the study is to evaluate whether there is a significant diurnal variation in the thickness of corneal epithelium and stroma, in healthy volunteers, using corneal optical coherence tomography (OCT).

Birefringent properties of the human cornea in vivo : towards a new model of corneal structure [PDF]

open access: yes
The fundamental corneal properties of mechanical rigidity, maintenance of curvature and optical transparency result from the specific organisation of collagen fibrils in the corneal stroma. The exact arrangement of stromal collagen is currently unknown

Hydrophilic lens effects on central and peripheral corneal thickness and corneal topography [PDF]

open access: yes, 1975
Hydrophilic lens wearing causes an almost evenly distributed central and peripheral corneal thickness increase which is virtually eliminated when gas of 100% oxygen tension is passed over the anterior corneal surface.
