  • Descrição: This study examined the effect of antiglaucomatous drops with different preservatives on corneal biomechanics using the ocular response analyzer (ORA) (Reichert Technologies, Inc., Depew, NY, USA). Patients using antiglaucomatous medical treatment containing a single agent combined with a preservative for at least 1 year who underwent a control examination between January and December 2017 at a glaucoma unit were included in this retrospective study. The patients were divided into 5 groups according to the antiglaucomatous agent and preservative ingredients. Measurements were taken with the ORA and compared with a control group. A total of 83 eyes treated eyes were included and analyzed. Thirty-three eyes of 33 patients were treated with latanoprost+benzalkonium chloride (BAC), 17 eyes of 17 patients were treated with travoprost+polyquad, 7 eyes of 7 patients were treated with bimatoprost+BAC, 18 eyes of 18 patients were treated with brimonidine+purite, 8 eyes of 8 patients were treated with brimonidine+BAC. A control group of 23 eyes of 23 healthy patients was also assessed for comparison. A significant decrease in corneal hysteresis (CH) and corneal resistance factor (CRF) was seen in the patients using bimatoprost+BAC and brimonidine+BAC when compared with the control group. Evaluation of the bimatoprost+BAC group and the latanoprost+BAC group revealed that the CH and the CRF was significantly lower in the group using bimatoprost+BAC (p<0.01). It has been reported that CH is a more important prognostic marker than central corneal thickness in glaucoma patients. Loss of visual field progresses faster in eyes with a low CH. Both preservatives and the active antiglaucomatous agents in medications can affect CH. Variation in CH in patients using antiglaucomatous drops over a long period is important in both the progression and follow-up of the disease.
