Background/Aim. Trabeculectomy is a safe procedure which effectively reduces the intraocular pressure (IOP). IOP is the most frequent indicator of success after glaucoma surgery. The aim of this work was to evaluate the long-term pressure control in primary open-angle glaucoma (POAG) and in pseudoexfoliative glaucoma (XFG) after primary trabeculectomy without the use of mitomycin-C (MMC), 3 to 5 years after trabeculectomy. Methods. This study involved a retrospective evaluation of 332 consecutive patients (352 eyes), 174 patients (188 eyes) with POAG (mean age of 64.0 ? 8.6 years) and 158 patients (164 eyes) with XFG (mean age of 70.7 ? 8.9 years) who underwent primary trabeculectomy between January 2007 and December 2009 at the Clinic for Eye Diseases, Clinical Center of Serbia in Belgrade. A successful control of IOP was defined as achieving IOP ? 21 mmHg without medication (complete success), or with a single topical medication (qualified success). Results. According to the type of glaucoma POAG/XFG preoperative IOP was 28.4 ? 6.3/30.4 ? 8.4 mmHg, respectively (p = 0.311) and last postoperative IOP was 16.9 ? 5.2/18.7 ? 5.9 mmHg, respectively (p = 0.681). According to the Kaplan-Meier survival curve, the complete success in the group with POAG in 1, 3 and 5 years were 85%, 75% and 58% and in the group with XFG were 82%, 70% and 56%, respectively. There was no statistically significant difference in the complete success rates between the patients with POAG and XFG. Conclusion. The primary goal of surgery was to achieve a sufficiently low IOP without additional medication, thus preventing progression of glaucomatous damage. In our study, the complete success in the group with POAG was achieved in 75% and 58% of the patients in the period of 3 and 5 years after surgery, respectively and in the group with XFG complete success was achieved in 70% and 56% of the patients respectively.

Purpose. To compare the effectiveness and safety of carbon dioxide (CO2) laser-assisted deep sclerectomy surgery (CLASS) and trabeculectomy (Trab) for treatment of primary open-angle glaucoma (POAG). Methods. In this retrospective and comparative study, 77 eyes of 62 patients with POAG were studied and divided into the CLASS and Trab groups. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of medications, surgical success rate, and complications were analyzed. Results. The mean follow-up periods were 27.89 ± 2.94 months and 26.11 ± 2.06 months in the CLASS and Trab groups, respectively. 30 eyes (24 patients) underwent CLASS and 47 eyes (38 patients) underwent Trab. The BCVA in the CLASS and Trab groups was recovered to baseline at postoperative 1 week and 1 month, respectively. At last follow-up visits, a remarkable reduction in the IOP and number of medications was observed in both groups, and no significant difference was found in those between the two groups. The complete success rates were 51.7% and 47.7% in postoperative 24 months in the CLASS and Trab groups, respectively ( P > 0.05 ). There were higher rates of delayed anterior chamber formation (21.3%) and thin-wall filtrating blebs (10.6%) in the Trab group. Meanwhile, the peripheral anterior synechiae were only observed in the CLASS group, and the ratio was 30%. Conclusions. CLASS is an effective and safe treatment modality for POAG, with fewer filtering bleb-related complications and quicker visual recovery in the early postoperative stage than trabeculectomy. The efficacy of lowering intraocular pressure was similar for both procedures.

Xen Implant

Purpose: The aim of this study was to compare the efficacy and safety of the XEN45 gel stent implant in patients with primary open-angle glaucoma or secondary open-angle glaucoma. Patients and methods: This is a retrospective, single-center, and comparative study conducted in consecutive primary open-angle glaucoma or secondary open-angle glaucoma patients, who underwent a XEN45 implant, alone or in combination with phacoemulsification. The primary end point was the intraocular pressure at the end of the follow-up period. Complete success was defined as an intraocular pressure reduction of ⩾20% from baseline to month 12 without antiglaucoma treatment. Results: Of the 69 patients (74 eyes) who were screened, 68 patients (73 eyes) were included in this study. In the overall study population, XEN gel stent significantly reduced intraocular pressure from 22.3 (21.0–23.5) mmHg at baseline to 15.3 (14.3–16.3) mmHg, p < 0.0001. As compared to baseline, mean intraocular pressure reduction was –7.3 (−9.7 to −5.0) and –6.6 (−8.4 to −4.8) mmHg in the primary open-angle glaucoma and secondary open-angle glaucoma groups, respectively, p = 0.6357. At month 12, 53 (72.6%) eyes were classified as success. The mean number of antiglaucoma medications was significantly reduced in both groups ( p < 0.0001, each). Complications included anterior chamber flattening (one eye), XEN implant extrusion (four eyes), one of whom had an endophthalmitis that required vitrectomy, and one eye underwent a trabeculectomy due to inadequate intraocular pressure control. Conclusion: XEN gel stent, either alone or in combination with phacoemulsification, provided a significant reduction in both intraocular pressure and medical antiglaucoma treatment, but with some safety concerns, in a cohort of patients with open-angle glaucoma (primary or secondary).

Purpose: To evaluate the clinical characteristics of newly diagnosed pseudoexfoliative glaucoma and compare them with those pertaining to newly diagnosed primary open-angle glaucoma as well as pseudoexfoliation syndrome. Methods: This case–control study involved 306 participants, including patients with newly diagnosed pseudoexfoliative glaucoma, age- and sex-matched normal controls, patients with newly diagnosed primary open-angle glaucoma, and subjects with pseudoexfoliation syndrome. The study was conducted at the Glaucoma Department of Clinic for Eye Diseases, Clinical Center of Serbia, as the referral center for glaucoma in Serbia. Results: The mean age in the pseudoexfoliative glaucoma, primary open-angle glaucoma, pseudoexfoliation syndrome, and normal control groups was 73.61 ± 8.46, 65.50 ± 8.97, 74.81 ± 6.80, and 73.58 ± 9.34 years, respectively (pseudoexfoliative glaucoma vs primary open-angle glaucoma, p < 0.001). Unilateral pseudoexfoliative glaucoma was diagnosed in 35 patients (42.2%). The intraocular pressure was higher in the eyes affected by pseudoexfoliative glaucoma (32.0 ± 9.5 mmHg) than that in the primary open-angle glaucoma eyes (28.8 ± 5.9 mmHg) (p < 0.001). In pseudoexfoliative glaucoma and primary open-angle glaucoma eyes, glaucoma severity was determined via the vertical cup-to-disk ratio (C/D) 0.65 (0.45–1.0) versus 0.60 (0.45–1.0), p = 0.048 and visual field mean deviation −5.68 (−1.58 to −30.9) versus −4.70 (−1.39 to −31.0), p = 0.045. Alzheimer’s was the only systemic disease associated with pseudoexfoliative glaucoma in the study sample, with an odds ratio of 0.021 (95% confidence interval = 0.00−21.52, p = 0.022). Conclusion: At the time of diagnosis, pseudoexfoliative glaucoma exhibits different clinical features compared with primary open-angle glaucoma. Higher intraocular pressure, narrow or occludable angle, increased trabecular pigmentation, phacodonesis, and poorer pupillary dilatation emerged as the factors associated with pseudoexfoliative glaucoma.

The Difference

Hypotensive effect of endotrabeculectomy was compared with that of selective laser trabeculoplasty in patients with primary open-angle glaucoma (POAG). We evaluated 44 patients (44 eyes) with POAG. In the first group (23 patients), endotrabeculectomy (trabecular ablation through the angle of anterior chamber) was performed, and in the second group (21 patients) the patients underwent selective laser trabeculoplasty. When comparing the intraocular pressure (IOP), it was found that the difference between preoperative and postoperative IOP was significant up to 6 months of follow-up in both groups (p < 0.05), however, hypotensive effect in the first group was more pronounced (7.58 vs. 1.55 mmHg, respectively). When comparing the number of hypotensive medications used before and after glaucoma surgery, it was found that the difference in patients of the first group was significant throughout the observation period (p = 0.028), while in patients of the second group there was no significant difference from the 3rd month of observation. The number of topical drugs to reduce IOP decreased by 1.44 in the first group (p < 0.05) and by 0.33 in the second group (p = 0.109). Endotrabeculectomy, as well as selective laser trabeculoplasty, showed significant hypotensive effect in patients with POAG within 6 months of observation, however, hypotensive effect of endotrabeculectomy significantly overweighted that of SLT.
