I think that computerized corneal topography analysis remains the primary tool for diagnosing keratoconus. I use corneal topography to look for early changes in the corneal shape and optics. when ...

Topography not foolproof While the corneal topographer is an integral part of the keratoconus detection process, it should not be relied upon for a diagnosis, urged Dr. Daniels.

Of 7 corneal topography indices, there were significant improvements in index of surface variance, index of vertical asymmetry, keratoconus index, and minimum radius of curvature (P < .001).

Detecting Ectatic Corneal Disorders. Ectatic corneal disorders, such as keratoconus, pellucid marginal degeneration, and keratoglobus, are considered contraindications to corneal refractive surgery.

For this study, corneal topography, medical history, best spectacle-corrected visual acuity, contact lens dependence, graft failure or rejection, and history of corneal transplant were used.

In both studies, the probability of inferior keratoconus in patients with crab claw patterns on corneal topography was found to be three times higher than the probability of PMD.

Diagnosis of keratoconus may also involve a specific imaging test called corneal topography to allow your doctor to examine changes to your eye that aren’t otherwise visible.

While keratoconus usually happens in both eyes, it may affect one eye more severely than the other. Learn more.

Keratoconus is a condition in which your eye's cornea is unable to hold its round shape. This can make your vision less clear. WebMD explains how to recognize and treat the condition.
