Diurnal variation of anterior segment parameters handled with Scheimpflug imaging in keratoconus patients

Purpose To define diurnal changes in anterior segment parameters of keratoconus patients by using Scheimpflug imaging. Methods All keratoconus patients had corneal topography measurements 3 times a day (around 09:00 AM, 13:00 PM and 17:00 PM) by the same experienced operator. Three consecutive scans...

Description
Summary:Purpose To define diurnal changes in anterior segment parameters of keratoconus patients by using Scheimpflug imaging. Methods All keratoconus patients had corneal topography measurements 3 times a day (around 09:00 AM, 13:00 PM and 17:00 PM) by the same experienced operator. Three consecutive scans in each measurement session were obtained. The average of three measurements was used for analysis. A repeated measures analysis of variance with one within-subject factor (time of day) was carried out to assess diurnal variation. Results This study included 26 eyes of 26 patients with keratoconus. Significant diurnal variation was found in CCT and TCT measurements ( P
