Related to Corneal diseases:keratoconus cor·ne·a (kôr′nē-ə) n. The transparent convex anterior portion of the outer fibrous coat of the eyeball that covers the iris and the pupil and is continuous with the sclera. [Medieval Latincornea (tēla),horny (tissue), from Latincorneus,horny...
In this study, corneal findings regarding keratoconus (KC) and early KC among mothers with Down syndrome children (MDS) and a group of age-at-delivery-matched mothers with normal children (MNC) were compared. KC was diagnosed based on the presence of a clinical sign and at least one ...
The top indications were Fuchs dystrophy (39% of all corneal transplants performed), a primary corneal edema mostly affecting elderly individuals; keratoconus (27%), a corneal disease that slowly deforms the cornea in young people; and sequellae of infectious keratitis (20%). The United States...
Keratoconus is a non-inflammatory progressive corneal ectatic disease associated with corneal thinning and abnormal bulging at one or both corneal surfaces, which leads to irregular astigmatism and visual impairment1. Although readily diagnosed based on the slit-lamp’s findings in the advanced stages, ...
Intrastromal corneal ring segments are considered medically necessary for reduction or elimination of myopia or astigmatism in persons with keratoconus or pellucid marginal degeneration who are no longer able to achieve adequate vision using contact lenses or spectacles and for whom corneal transplant is ...

Corneal trauma, or scarring near the cornea that can result in a change in shape. Astigmatism, especially aftercorneal transplant surgery (keratoplasty). Keratoconus (detecting early signs of the disease and monitoring progression). If you have an eye disease that requires steady monitoring, your...
[1]. Keratoconus diagnosis was based on corneal topography and slit-lamp observation. In all cases, preoperative findings characteristic of keratoconus was confirmed; that is, corneal topography revealing an asymmetric bow-tie pattern with or without skewed axes and at least one keratoconus sign on ...
The keratoconus enigma: A review with emphasis on pathogenesis Giulio Ferrari, Paolo Rama, in The Ocular Surface, 2020 4.2 Corneal nerves Prominent corneal nerves are a well-known clinical feature of KC. It has been postulated that this is a consequence of corneal thinning and increased visibility...
This progressive distortion and bowing out (coning) of the normal cornea creates optical aberrations, which can be thought of as static in your eye (like static on an old TV), resulting in a decrease in visual function. Because of the corneal distortion in keratoconus, patients usually require...
