Estimation of axial curvature of anterior sclera: correlation between axial length and anterior scleral curvature as affected by angle kappa
BACKGROUND: Though the development and fitting of scleral contact lenses are expanding steadily, there is no simple method to provide scleral metrics for scleral contact lens fitting yet. The aim of this study was to establish formulae for estimation of the axial radius of curvature (ARC) of the anterior sclera using ocular biometric parameters that can be easily obtained with conventional de...
متن کاملEffect of scleral shortening on axial length.
BACKGROUND Partial thickness sclerectomy is the most commonly employed scleral shortening technique used in conjunction with pars plana vitrectomy in the repair of myopia-associated macular holes in patients with staphyloma. Recently, scleral shortening induced through scleral invagination has been advocated as an adjunct in retinal translocation surgery. OBJECTIVE To determine whether a corr...
متن کاملScleral Cross Section Area and Volume and Axial Length
PURPOSE To examine whether the scleral cross sectional area and estimated scleral volume are associated with a longer axial length in human eyes. METHODS Histologic anterior-posterior sections running through the pupil and the optic nerve head were examined. Using a light microscope, we measured the thickness of the sclera at the limbus, ora serrata, equator, midpoint between equator and post...
متن کاملScleral remodeling during the development of and recovery from axial myopia in the tree shrew.
PURPOSE Recent investigations have suggested that scleral thinning in mammalian eyes with axial myopia is a consequence of the loss of scleral tissue, rather than the redistribution of existing tissue as the eye enlarges. The present study investigated whether further changes in the distribution and metabolism of scleral tissue occur during the process of recovery from axial myopia. Scleral gly...
متن کاملAxial length of myopia: a review of current research.
Myopia, or nearsightedness, is a worldwide common type of refractive error. It is a non-life-threatening disorder with huge social and economic consequences due to its increasing prevalence. Axial length (AL) is the primary determinant of non-syndromic myopia. It is a parameter representing the combination of anterior chamber depth, lens thickness and vitreous chamber depth of the eye. AL can a...
