Benchmarking Keratoconus

Keratoconus is a common corneal disorder where the central or paracentral cornea undergoes progressive thinning and steepening, generating the classic cone-shaped cornea that yields irregular astigmatism. The causes are unclear, but a number of genetic and environmental factors have been implicated.

To provide insight into the past and predictions for the future of the field, a series of metrics were applied to the last five years of the published literature. We asked:

What are the major topics for the field?
Which publications have the greatest impact?
How is the knowledge available online?
Who are the most prolific authors?

PubMed was searched for: keratoconus, with results limited to the last five years, in humans (for a clinical focus). The data were analyzed in Microsoft Excel 2013.
