Objectives. To evaluate 24-hour intraocular pressure (IOP) variation in patients with primary open-angle glaucoma (POAG) treated with triple eye drops. Subjects and Methods. The IOP was measured in 74 eyes in 74 POAG patients (seated) on triple therapy (PG analogue, β-blocker, carbonic anhydrase inhibitor) at about every 3 hours. Results. The peak IOP was 13.5 ± 3.1 at 1:00, and the trough IOP was at 12.6 ± 2.4 mmHg at 7:00. The IOP at 7:00 was significantly lower than that at 10:00, 1:00, and 3:00 (p<0.05). Based on the time of the peak IOP, we classified the patients into two groups: diurnal (28 eyes) and nocturnal types (37 eyes). There was significant difference at the spherical equivalent between diurnal and nocturnal types (p=0.014). To assess the influence of reflective error, we conducted subanalysis for two groups: high myopic (26 eyes, ≤−6D) and low/nonmyopic (24 eyes, ≥−2D) groups. In the low/nonmyopia group, the IOP was significantly higher at 1:00 and 3:00 than at 13:00, 16:00, and 7: 00 (p<0.05). Conclusion. The mean of IOP elevated outside of clinic hour in the POAG patients on triple therapy. The low/nonmyopia patient should be carefully treated because the IOP of the patients at night elevated significantly.

Objective: The aim of this study is to compare the efficacy of the trabeculectomy in controlling intraocular pressure in patients with primary open-angle and pseudo-exfoliation glaucoma. Materials and Methods: The medical data of a sum of 69 eyes of which 36 (52,2%) with primary open angle glaucoma (POAG) and 33 (47,8%) with pseudo-exfoliation (PEG), who have medically uncontrolled glaucoma and had undergone primary trabeculectomy in Göztepe Education and Research Hospital were evaluated in this retrospective study. Postoperatively, data at the first day, at the first month, and at the last examination evaluated in the study. Success of the surgery is defined as measurement of intraocular pressure under 21 mmHg with (incomplete success) or without (complete success) additional medications following the end of the first year follow-up examinations. Results: POAG group consists of 36 patients of which 16 male, 20 female and PEG group consists of 33 patients of which 21 male and 12 female. The mean age was 67.2±9.1 (42-80) years in POAG group and 70.7±6.6 (55-80) years in PEG group. There was no statistically significant difference between POAG and PEG groups in visual acuity, mean intraocular pressure, c/d ratio and the number of antiglaucomatous medications preoperatively and postoperatively (p>0.05). There was a statistically significant difference in groups between post and preoperative values in visual acuity, mean intraocular pressure, c/d ratio and the number of antiglaucomatous medications (p<0.05) Success of the trabeculectomy was 41,7% (complete success), 41,7% (incomplete success) and remaining 16,6% was unsuccessful, in POAG group and success rate in PEG group was 51.5%, 27,3% and 21,2% respectively. There was no statistically significant difference between groups (p=0.738). Conclusion: Trabeculectomy is an effective surgery in lowering intraocular pressure in both of the study groups equally.

Purpose To evaluate with color Doppler imaging (CDI), in patients with primary open-angle glaucoma (PDAG), the possible influence on ocular hemodynamics of a beta-blocking agent with intrinsic sympathomimetic acitivity (carteolol 2%) compared to a beta-blocker agent without this activity. Methods A study was carried out on 20 patients, with bilateral POaG, intraocular pressure (IOP) ≤ 20 mmHg, all treated twice a day with timolol maleate 0.5% ophthalmic solution. The visual field was evaluated (Octopus 2000 perimeter, G1 program) examining the mean sensitivity (MS) and the mean defect (MD). CDI was carried out to evaluate the resistance index of the internal carotid artery (ICA), the ophthalmic artery (OA), the central retinal artery (CRA), and the short posterior ciliary arteries (SPCA). After these examinations, the therapy was changed to carteolol 2% twice a day. After six months of treatment the examinations were repeated. The data were analysed statistically using Student's t test. Results The mean intraocular pressure during treatment with timolol 0.5% was 16.7 ± 1.67 mmHg and 16.33 ± 1.72 mmHg after treatment with carteolol 2%, the difference not being significant (p=0.494). After six months of treatment with carteolol 2% the MS increased significantly from 22.4 ± 2.5 dB to 24.1 ± 1.8 dB (p=0.018), and the mean defect (MD) fell from 5.3 ± 0.8 dB to 4.7 ± 0.6 dB (p=0.011). There was no significant difference in the resistance index of the CA, the OA and the CRA with the two treatments, whereas the resistance index of the SPCA dropped significantly, from 0.80 ± 0.05 to 0.77 ± 0.02 (p = 0.017). Conclusions CDI did not show significant differences in the resistance indexes of the internal CA, the OA, and the CRA after treatment with carteolol 2% but the resistance index of the SPCA was significantly reduced. Carteolol 2% induced significant changes in the perimetric indexes examined, with an increase in MS and a decrease in MD. These findings suggest that the intrinsic sympathomimetic activity of carteolol may reduce peripheral vascular resistance of the SCA, thus improving perfusion of the optic nerve head, with a protective effect on visual function.

Purpose: To evaluate the long-term effectiveness of iTrack (Nova Eye Medical, Fremont, USA) ab-interno canaloplasty performed as a standalone procedure, or combined with cataract surgery, in reducing antiglaucoma medication dependence and maintaining intraocular pressure within target range in patients with controlled primary open-angle glaucoma. Methods: This is a retrospective, single-center, case series study of patients who underwent iTrack ab-interno canaloplasty as a standalone procedure ( n = 34) or in combination with cataract surgery ( n = 11). Eyes with controlled mild or moderate glaucoma (intraocular pressure ⩽17 mmHg) were included; those with prior glaucoma surgeries were excluded. The primary outcome was the mean reduction in glaucoma medication and the secondary outcome was the maintenance of controlled intraocular pressure postoperatively. Results: A total of 35 patients (45 eyes) with a mean age of 73 ± 9.7 years were included in the study. For all eyes, a significant decrease (61%) in the mean number of medications was seen at 36 months (1.89 ± 0.93 versus 0.60 ± 0.82; p < 0.001), with 56% (14/25) of eyes medication free. No significant difference was observed in the reduction of medication use whether iTrack was performed with or without cataract surgery at 12 and 36 months. Mean baseline intraocular pressure of 14.42 ± 2.2 mmHg for all eyes was maintained at the 12-, 24-, and 36-month follow-up visits (14.6 ± 3.65, 15.06 ± 2.26, and 14.19 ± 2.91, respectively), with no significant difference between the two groups ( p = 0.08). Conclusion: The iTrack ab-interno canaloplasty significantly reduced medication dependency and maintained intraocular pressure within target range in patients with controlled mild or moderate primary open-angle glaucoma, while showing a good safety profile, both as a standalone procedure or in combination with cataract surgery.

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: The aim of this study is to compare the outcomes of micropulse transscleral cyclophotocoagulation between primary open-angle glaucoma, pseudoexfoliation glaucoma, and other types of secondary glaucoma. Methods: Outcomes of 96 consecutive patients with refractory, end-stage glaucoma treated with micropulse transscleral cyclophotocoagulation were retrospectively reviewed. Follow-up examinations were performed on a regular basis until 12 months postoperatively. Surgical successes were defined as maintaining intraocular pressure ⩽18 mmHg and ⩾20% reduction in intraocular pressure (criteria A), ⩽15 mmHg intraocular pressure and ⩾25% reduction in intraocular pressure (criteria B), and ⩽12 mmHg intraocular pressure and ⩾30% reduction in intraocular pressure from baseline (criteria C). Results: Ninety-six eyes of 96 patients (50 (52%) females, 46 (48%) males) were included. Among all eyes, 32 were primary open-angle glaucoma, 30 were pseudoexfoliation glaucoma, and 34 were other types of secondary glaucoma. The mean age was 59.37 ± 11.45 (range: 20–91) years. The mean follow-up period was 14.2 ± 3.9 (range: 12–16) months. At 12 months, the success rates of primary open-angle glaucoma, pseudoexfoliation glaucoma, and secondary glaucoma group were 68.75%, 66.6%, and 64.7% (p = 0.185) for criteria A; 56.25%, 53.3%, and 50% (p = 0.153) for criteria B; and 43.75%, 43.3%, and 38.2% (p = 0.146) for criteria C. Four patients (12.5%) in primary open-angle glaucoma group, 5 patients (16.6%) in pseudoexfoliation glaucoma group, and 14 (41.2%) patients in other secondary glaucoma group required reoperation during the follow-up (p < 0.05). Conclusion: Micropulse transscleral cyclophotocoagulation is an equally effective method of lowering intraocular pressure in patients with primary open-angle glaucoma, pseudoexfoliation glaucoma, and other types of secondary glaucoma. The rate of reoperation was higher in refractory secondary glaucoma patients.

PurposeTo characterise the genotype(s), phenotype(s) and age-related penetrance of glaucoma in a Chinese family with primary open-angle glaucoma (POAG).MethodsRecruited from a Chinese family spanning four generations, 7 individuals with POAG, 1 with ocular hypertension (OHT) and 14 unaffected individuals were included in this study. Genotypic investigation included sequencing of mutation sites using a glaucoma panel in combination with high-throughput sequencing and validated using Sanger sequencing. Phenotypic characterisation included investigation into patient medical history and physical examination.ResultsEight (36.4%) family members harboured heterozygous Y437H mutation, of whom seven (87.5%) were glaucomatous and one (12.5%) had OHT. The mean age of POAG diagnosis was 30.85±7.13 years. The mean highest recorded intraocular pressure (IOP) was 46.57±6.53 mm Hg. They all had complained of symptoms associated with vision and pain. Four (57.1%) patients presented blindness. Five eyes (62.5%) presented with severe and three eyes with moderate visual field defects. Most of them underwent surgery on average 1.29±2.36 years after diagnosis, and the mean IOP at study was 17.95±7.23 mm Hg, with an average of 0.92±0.86 eye-drops. The patient with OHT was treated with latanoprost only and her IOP was well controlled. Age-related glaucoma penetrance was 0% in individuals under the age of 20 years, 50% at ages 20–35 years, 75% at ages 31–35 years and 87.5% over 45 years.ConclusionA novel MYOC mutation (c.1309T>C, p.Y437H) in a Chinese family with POAG was identified which was associated with a phenotype characterised by severe visual impairment, frequent surgical intervention requirement and relatively high penetrance.

Purpose: To compare the efficacy and safety of bimatoprost (0.03 %) and travoprost (0.004 %) in patients with primary open angle glaucoma (POAG). Subjects and methods: Patients with POAG were randomized to receive either bimatoprost or travoprost once daily. Detailed ocular examination was done and intraocular pressure (IOP) was measured at 9.00 am, 1.00 pm and 4.00 pm at the baseline and at 1, 2, 4, 6 and 12 weeks of therapy. Results: A total of 31 patients were analysed. The patients were randomly divided into two groups (Bimatoprost group = 16; Travoprost group = 15). Both the groups had a statistically significant reduction from the baseline IOP at all follow up visits at 9.00 am, 1.00 pm and 4.00 pm. The mean IOP decreased from a baseline of 25 ± 2.32 mm Hg to 15.93 ± 1.79 mm Hg after 12 weeks in the bimatoprost group (p < 0.001), and from 24.2 ± 1.60 mm Hg to 16.53 ± 1.56 mm Hg in the travoprost group (p < 0.001). A better mean reduction of IOP was obtained with bimatoprost than with travoprost at the end of the study at 12 weeks (p = 0.03). Mild ocular redness was the commonest side effect in both the groups but was not significant in either group. Conclusion: Both drugs lowered IOP effectively but bimatoprost showed a greater reduction in the mean IOP than did travoprost at 12 weeks and both are safe for ocular use.

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.

BackgroundTo review the changes in intraocular pressure (IOP) following topical hypotensive medications washout in patients with primary open angle glaucoma (POAG), ocular hypertension (OHT) and uveitic glaucoma (UG)/OHT.MethodsThe study included 120 patients with POAG, OHT and UG recruited from prospective clinical trials between February 2013 and July 2017. We excluded 20 eyes with IOP of ≤21 mm Hg, 11 eyes with previous incisional surgery and 17 eyes with incomplete data. UG eyes with active inflammation and on steroid treatment were excluded. Participants underwent a 1-month washout period from topical ocular hypotensive medications before IOP phasing. Comparisons were made between pre/post-washout IOP, and highest-recorded (peak) and post-washout IOP.ResultsA total of 110 eyes with POAG, 33 eyes with OHT and 43 eyes with UG were included for analysis. The mean pre-washout IOP was 18.1±3.3 mm Hg in POAG, 18.8±3.3 mm Hg in OHT and 17.9±8.8 mm Hg in UG; the mean post-washout IOP was 26.6±4.8 mm Hg, 26.4±3.9 mm Hg, 23.1±10.1 mm Hg in POAG, OHT and UG, respectively. The mean increase in IOP after washout was significantly lower in UG compared with POAG and OHT eyes (p=0.01). The percentage of eyes with post-washout IOP <22 mm Hg was 12.7% in POAG, 6.1% in OHT and 51.2% in UG.ConclusionActive inflammation and steroid treatment contributes to elevated IOP in uveitis. Therefore, IOP may revert to normal once inflammation subsides. We recommend ocular hypotensive treatment washout to be considered in UG eyes that have IOP under control in the absence of recurrence of uveitis.
