Anterior keratoconus associated with unilateral cornea guttata.

PURPOSE: To describe a 30-year-old man with bilateral but asymmetric anterior keratoconus and unilateral cornea guttata in the eye with more advanced keratoconus.

METHOD: Case report.

RESULTS

The patient's keratoconus was diagnosed three or four years earlier. The keratoconus was confirmed by slit-lamp examination, keratometry, and computer-assisted topographic analysis. Cornea guttata were confirmed by clinical examination and specular microscopy.

CONCLUSION

This is a rare case of unilateral cornea guttata associated with asymmetric keratoconus, showing severe guttate change only in the eye with more advanced keratoconus.
