The Maximum Color Contrast Sensitivity Test for Detecting Early Changes in Pituitary Adenomas

Abstract

Purpose. To evaluate maximum color contrast sensitivity (MCCS) in patients with recurrent and non-recurrent PA.

Materials and methods. 126 eyes of 63 patients with PA were included in the study. Color contrast sensitivity was analysed with the MCCS test.

Results. A total of 162 participants were enrolled in the study. Sixty three patients were diagnosed with PA. Nine patients were diagnosed with recurrent PA. The average error score of MCCS test was 1.33 ± 0.649 in the control group, and 3,806 ± 3,425 in the group with PA. Test results range from 0,26 to 3,5 in the healthy patients, and from 0,66 to 18,36 in the patients with PA. There was no significant difference between the group with recurrent PA and the group with non–recurrent PA group (63,03 vs 66,33 (mean rank), respectively; p=0,72).

Conclusion. The results of MCCS test were significantly higher in the healthy people than in the participants with PA (p<0,001), but there was no significant difference between the group with recurrent PA and the group with non–recurrent PA group (p=0,72).
