RESUMO
Purpose: To evaluate the effects of micropulse transscleral cyclophotocoagulation (mCPC) and selective laser trabeculoplasty (SLT) on endothelial cell density (ECD) and reduction of the intraocular pressure (IOP) in patients with primary-open angle glaucoma (POAG). Patients and Methods: In this observational, retrospective study, 40 eyes with POAG were included. Patients were divided into three groups-group I was treated with SLT (n = 13), group II was treated with mCPC (n = 13), and group III included age-matched patients with medically treated glaucoma (n = 14) (control group). In both treatment groups (SLT and mCPC) preoperative and postoperative findings of best-corrected visual acuity (BCVA), ECD, and IOP were compared to the control group. Results: The mean time interval before and after the treatment was 215 ± 120 days in group I (SLT) and 273 ± 177 days in group II (mCPC). The follow-up for group III (control group) was 209 ± 103 days. In both treatment groups (SLT and mCPC) there was a statistically significant reduction of the IOP postoperatively (group I: 3.5 ± 3.7 mm Hg (p = 0.005) and group II: 4.3 ± 4.1 mm Hg (p = 0.003)). The mean IOP for group III was 12.9 ± 3.7 mm Hg at visit 1 and did not change significantly (p = 0.353) at visit 2. In all three groups, there was no statistically significant change in ECD at the last visit. Conclusion: According to our results, both SLT and mCPC seem to be effective in lowering the IOP, without showing any statistically significant effect on ECD in patients with POAG.However, larger and longer-term studies are necessary to understand the effects of the SLT and mCPC procedures on ECD.

RESUMO
PURPOSE: To evaluate the correlation of the intraocular pressure measurements (IOP) with non-contact tonometer Corvis Scheimpflug technology (Corvis ST), Goldmann applanation tonometry (GAT), ocular response analyzer (ORA), and iCARE rebound tonometer in patients with thyroid-associated orbitopathy (TAO) and eye-healthy subjects (control group). METHODS: Twenty-nine consecutive patients with TAO (79% female) and 30 eye-healthy subjects (60% female) were included in this prospective, age- and sex-matched study. The IOP measurement with Corvis, ORA, GAT, iCARE, and central corneal thickness (CCT) with Corvis was obtained from all study participants. RESULTS: The mean age of the patients was 51 ± 10 years in patients with TAO and 56 ± 13 years in the control group. The mean IOP measurements with GAT, Corvis, ORA, and iCARE were 15.93 ± 4.42 mmHg, 18.10 ± 7.54 mmHg, 18.40 ± 7.93 mmHg, and 16.61 ± 7.96 mmHg in patients with TAO and 14.52 ± 3.02 mmHg, 14.48 ± 3.38 mmHg, 15.29 ± 4.64 mmHg, and 14.13 ± 3.85 mmHg in the control group (P = 0.157, P = 0.004, P = 0.017, and P = 0.176 respectively). The mean CCT was 547.5 ± 39.2 µm in patients with TAO and 560.8 ± 49.8 µm in the control group ( P= 0.261). CONCLUSIONS: The data collected shows an agreement between the iCARE and GAT IOP measurements in TAO patients and in eye-healthy patients. However, the mean value of IOP measurements with Corvis and ORA was significantly higher in patients with TAO in comparison with the control group (P = 0.044 and P = 0.029 respectively).
