Romatoid Artritli Hastalarda Oküler Cevap Analizörü ile Ölçülen Korneal Biyomekanik Özelliklerin Değerlendirilmesi

Purpose: To compare the corneal biomechanical properties using an ocular response analyzer (ORA) in patients with\udrheumatoid arthritis and healthy control subjects.\udMaterial and Method: Thirty four eyes of 17 healthy individuals (control group) and 34 eyes of 17 patients with RA\ud(study group) were recruited. ORA measurements were performed in all patients. Corneal-compensated intraocular\udpressure (IOPcc), Goldman related intraocular pressure (IOPg), corneal resistance factor (CRF), and corneal hysteresis\ud(CH) were recorded. Statistical analyses were performed using a t test for independent samples.\udResults: In the study group, mean CH was 11.5±2.1 (7.7-16.2) mmHg, mean CRF was 12.1±2.3 (8.2-17) mmHg, IOPg\ud17.2±4.4 (8.3-25.1) and mean IOPcc was 16.5±4.3 (7.7-24.2) mmHg. In the control group, mean CH was 11.6±1.1\ud(9.7-13.8) mmHg, mean CRF was (11.8±1.2 (9.8-14.1) mmHg, IOPg 15.9±3.3 (9.4-25.7), and mean IOPcc was\ud15.4±2.6 (8.8-21.2) mmHg. There were no significant differences in these parameters between the study and control\udgroups (p>0.05).\udDiscussion: The biomechanical parameters measured with ORA were not statistical difference in patients with rheumatoid arthritis\udand age matched healthy individuals.
