Purpose To evaluate differences in corneoscleral shape keratoconus patients with and without specialty lenses compared to controls. Methods A cross-sectional study was performed comparing three groups of eyes: 24 lens-naïve eyes (17 patients; group 1), 7 corneal lens wear (7 2) scleral 3). For comparison, 25 emmetropic participants 11 astigmatic were included. Corneoscleral topography measureme...

Concussion injury to the globe, if not severe enough to rupture the outer coat, causes a temporary expansion of the posterior sclera. This may pass unnoticed without producing any lesion, or may be severe enough to rupture the adjacent vascular structures. The circle of Zinn, by its particular situation around the optic nerve and within the sclera, is liable to such injury and its rupture is a ...

Introduction Fibrous connective tissues like sclera, skin, tendon and cornea have a high content of collagen but only small amounts of proteoglycans and structural glycoproteins. The specific blend of collagen and proteoglycan types determines the properties of the tissue. The proteoglycans are characterized by having a central protein core substituted by one or several glycosaminoglycan chains...

A new screening technique for neonatal jaundice is proposed exploiting the yellow discoloration in the sclera. It involves taking digital photographs of newborn infants' eyes (n = 110) and processing the pixel colour values of the sclera to predict the total serum bilirubin (TSB) levels. This technique has linear and rank correlation coefficients of 0.75 and 0.72 (both p<0.01) with the measured...
