A Retrospective Study Of The Clinical Profile Of Keratoconic Patients At Ferris State University Optometry Clinic.

We conducted a retrospective study of the records of 40 keratoconic patients presenting at the Ferris State University Optometry Clinic. The purpose of this study was to develop a clinical profile of the presentation of an average keratoconic patient. Parameters examined included the sex of the patient, the age of the patient at the time of diagnosis, initial keratometric readings, initial best visual acuity, initial corneal signs, laterality, history of eye rubbing, and family history. The progression of the disease was also studied by noting if the patients were fit with rigid gas permeable contact lenses, if surgery was indicated, and any corneal signs which developed during the time they were followed. A rate of change of the keratometric readings was also calculated in order to quantify the progressive steepening of the cornea. Lastly, data from the patients' most recent examination and corneal topography was studied to determine the most recent best visual acuity and the position of the cone itself.
