Abstract Details


To evaluate the differences between Optical, Ultrasonic and Scheimpflug camera systems for measurement of central corneal thickness (CCT) in normal population.


Okan University Hospital


We included 40 eyes of 40 consecutive patients with normal ophtalmic examinations. Exclusion criteria were topograpic abnormalities, history of ocular surgery, ocular surface disease, using ocular or systemic medication, glaucoma, retinal disease or uveitis.


Mean age of patients was 36,77 �Â�± 13,38. Mean CCT measured by Optic pachmeter was 564,61 �Â�± 46,28 �Â�µ; by Scheimpflug system was 553 �Â�± 48,23 �Â�µ; by Ultrasound was 555,88 �Â�± 48,23 �Â�µ. There was no statistically significant difference between the measurements of Scheimpflug camera and Ultrasound systems (p>0,05); but the measurements of optical pachmeter was found to be thicker than the two other measurements (p �Ë�‚0,05).


Scheimpflug camera seems to demonstrate better agreement with ultrasonic pachymetry as compared to optical pachymeter.
