AbstractProstaglandin (PG) analogues are usually prescribed as a first-line therapy in patients with glaucoma because of its once-daily dosing benefit and effective intraocular pressure (IOP) reduction. However, the mechanism of PG analogues is not completely understood. In this study, we investigated the effect of PG analogues on the anterior scleral thickness (AST) in treatment-naïve eyes with primary open-angle glaucoma using anterior segment optical coherence tomography. The AST was measured at the location of the scleral spur, 1000 μm, and 2000 μm posterior to the scleral spur and was compared before and after using the medications for 3 months and 1 year. Among 54 patients enrolled in this study, 31 patients used prostaglandin analogues and 23 patients used dorzolamide/timolol fixed combination (DTFC) drugs. There was no significant difference in untreated IOP, glaucoma severity, and baseline AST values between the two groups. While there was no significant changes in AST after using the DTFC drugs, the AST at all 3 locations showed a significant reduction in both the nasal and temporal sectors after using PG analogues for 1 year (all, P < 0.05). These findings suggest that the AST reduction after using PG analogues might be related with the increased uveoscleral outflow.

Purpose. To evaluate thein vivochanges in Schlemm’s canal (SC) and the trabecular meshwork (TM) in patients with primary open-angle glaucoma (POAG) after phacocanaloplasty using anterior segment optical coherence tomography (AS-OCT).Methods. Ten eyes of nine patients with POAG (6 men and 3 women) who underwent phacocanaloplasty. Preoperative and postoperative visual acuity (VA), intraocular pressure (IOP), and use of glaucoma medications were evaluated. The main outcome measures were the area of SC and TM thickness assessed using AS-OCT before and 12 months after surgery.Results. We found statistically significant reduction in IOP (from 26.4 (8.6) mmHg to 12.9 (2.5) (p<0.05) mmHg), increase in VA from 0.7 (0.4) to 0.9 (0.2), and decrease in glaucoma medication from 2.6 (1.2) to 1.1 (1.3) at 12 months postoperatively. There was a significant increase in the SC area (3081.7 (842.8) μm2versus 5098.8 (1190.5) μm2,p<0.001) and a decrease in mean TM thickness (91.2 (18.6) μm versus 81.3 (15.1) μm,p=0.001) after surgery. We found negative correlations between SC area and IOP before surgery (r=-0.67,p=0.03) and also between SC area before and IOP reduction 12 months after the phacocanaloplasty (r=-0.80,p=0.005).Conclusions. Our results showed statistically significant dilation of SC area and reduction of TM thickness after phacocanaloplasty in POAG patients. The degree of SC expansion was related to the IOP decrease.

Result Analysis

Background: Glaucoma patients often come with intraocular pressure (IOP) that reach target pressure, but still have glaucoma progression due to IOP fluctuation. Water drinking test (WDT) can be used as a method to predict IOP fluctuation.Purpose: To compare prostaglandin analogue (PGA) and selective laser trabeculoplasty (SLT) capability to maintain IOP fluctuation on primary open angle glaucoma (POAG).Method: This clinical experimental research was conducted at Dr. Kariadi Hospital. Subjects were POAG patients selected with consecutive sampling. Intraocular pressure was measured before and after WDT. After WDT, IOP was measured every 15 minutes until 1 hour. Peak IOP and IOP fluctuation data were collected then analyzed with t-test.Results: Forty two eyes from 30 POAG patients were analyzed. Twenty six eyes in PGA group and 16 eyes in SLT group. Most of the subjects were male with mild glaucoma degree. WDT increased IOP significantly on both groups. Mean IOP pre WDT was 14.58 ± 2.580 mmHg and 16.94 ± 2.645 mmHg in PGA and SLT groups. Mean peak IOP post WDT was 22.73 ± 4.114 mmHg and 25.75 ± 5.859 mmHg in PGA and SLT groups. Mean IOP fluctuation was 8.15 ± 4.202 mmHg and 8.81 ± 5.344 mmHg in PGA and SLT groups. Peak IOP and IOP fluctuation result analysis on both groups were not significantly different.Conclusion: Prostaglandin analogue and SLT had equal capability to maintain IOP fluctuation but still higher than normal fluctuation (>6 mmHg) that affects glaucoma progression.
