Our report is only the second to describe such findings. Un like the patient described by Stefani et al,3 our patient did not have diplophthalmos or gross craniocervical deformities.

External ocular examination revealed 30 diopters of left exotropia. Results of slit-lamp examination of the right eye were normal. The left cornea resembled a horizontally oriented hourglass with the longest diameter (horizontal) measuring 15 mm and
