Hyaline ridges on the posterior cornea.
HYALINE or glassy ridge formation on the posterior corneal surface appears to be a not uncommon phenomenon, the recognition of which may be missed without careful examination with the slit-lamp microscope. Normally, Descemet's membrane is secreted as a hyaline tissue by the endothelial corneal cells during intra-uterine life; the exact point of development at which it appears is not definitely ...
متن کاملPosterior conical cornea.
SINCE this condition was first described (Butler, 1930), only a handful ofcases has been added to the literature. In view of its infrequency, some cases are presented and compared with previous descriptions. Perhaps the name, although anatomically descriptive, is unfortunate, for it would imply that the condition has some relationship with the better-known conical cornea. In fact, there is no e...
متن کاملThe posterior cornea: hiding in plain sight.
For more than 100 years, eye scientists and clinicians have recognized that there is a difference between the refractive and anterior corneal astigmatism of the human eye. Javal postulated an approximately linear relationship between corneal astigmatism and refractive astigmatism, which became known as Javal’s rule: refractive astigmatism 1⁄4 1.25 (keratometric astigmatism) 0.50 90. For most ey...
متن کاملPathology of posterior polymorphous degeneration of the cornea.
POSTERIOR polymorphous degeneration of the cornea is an uncommon, non-progressive, hereditary condition which is usually bilateral; in the majority of cases there is only minimal visual impairment (Duke-Elder and Leigh, 1965). The condition was first described by Koeppe (1916) as "keratitis bullosa interna", on account of the congenital pits on the posterior corneal surface. Koeppe (1920) repor...
متن کاملInfectious crystalline keratopathy predominantly affecting the posterior cornea.
A case of infectious crystalline keratopathy that affects mainly the posterior stroma is presented. Crystalline infiltrates presented after multiple epithelial defects and chronic topical steroid use following a penetrating keratoplasty in this patient. His epithelial defects persisted and given the deep location of the crystalline infiltrates, a penetrating keratoplasty was performed again. Sl...
