A case report of keratoconus with regular astigmatic topography.
OBJECTIVE
To describe an interesting case in which use of standard corneal topography in isolation from clinical observations could have misdiagnosed keratoconus as regular astigmatism.


METHODS
Single patient case report.


RESULTS
Our patient received the correct diagnosis and appropriate contact lens treatment that resulted in optimal vision and tolerance. CONCLUSIONS. Use of either or both careful clinical slit lamp biomicroscopy and history or more sophisticated corneal topography analysis can detect keratoconus that standard corneal topography used in isolation from other clinical investigations may misdiagnose.
