How is keratoconus diagnosed on topography?

Topographic diagnosis of keratoconus is suggested by:

1. High central corneal power.
2. Large difference between the power of the corneal apex and periphery.
3. Differences in steepness between the two corneas of a given patient.

What is pentacam eye test?

It is a noncontact examination that photographs the surface of the eye. Pentacam is not a routine test. Rather, it is used in diagnosing certain types of problems, in evaluating a disease’s progression, in fitting some types of contact lenses, and in planning surgery.

Can the Pentacam be used to screen corneas?

“A few surgeons are using only the Pentacam for screening corneas, but I believe that’s a mistake,” he continues. “The Pentacam displays a corneal topography map, but the measurements are actually generated from tomographic data, based on corneal shape and elevation.

What is Keratoconus (KC)?

Keratoconus (KC), a form of corneal ectasia, is a bilateral, asymmetrical, noninflammatory pathology characterized by progressive, localized thinning and protrusion of corneal tissue (Gokhale, 2013).

What is the prevalence of keratoconus in the US?

Keratoconus is a degenerative, bilateral, asymmetric, and noninflammatory corneal disorder with a previously established prevalence of approximately 1/2000 or 0.05 percent among the general population. However, recent epidemiology studies have reported prevalence rates as high as 2.5 percent in different regions of the world.
