travoprost and Glaucoma--Angle-Closure

To determine the effectiveness of argon laser peripheral iridoplasty (ALPI) in primary angle closure (PAC) and primary angle-closure glaucoma (PACG).. Randomized controlled trial.. Eighty PAC or PACG subjects who underwent laser iridotomy (LI) and had at least 180° of persistent appositional angle closure and intraocular pressure (IOP) of more than 21 mmHg were enrolled.. Subjects were randomized to receive either 360° ALPI (Visulas 532s; Carl Zeiss Meditec, Jena, Germany) or medical therapy (Travoprost 0.004%; Alcon-Couvreur, Puurs, Antwerp, Belgium). Repeat ALPI was performed if the IOP reduction was less than 20% from baseline along with inadequate angle widening at the month 1 or month 3 visit. Intraocular pressure was controlled with systematic addition of medications when required.. The primary outcome measure was success rates after ALPI at 1 year. Complete success was defined as an IOP of 21 mmHg or less without medication, and qualified success was defined as an IOP of 21 mmHg or less with medication. Failure was defined as an IOP more than 21 mmHg despite additional medications or requiring glaucoma surgery.. Forty subjects (51 eyes) were randomized to ALPI and 40 subjects (55 eyes) were randomized to medical therapy. Complete success (IOP ≤21 mmHg without medication) was achieved in 35.0% eyes of the ALPI group compared with 85.0% of eyes in the prostaglandin analog (PGA) group (P < 0.001), and qualified success (IOP ≤21 mmHg with medication) was achieved in 35.0% and 7.5%, respectively (P = 0.003). The IOP decreased by 4.9 mmHg (95% confidence interval [CI], 3.5-6.3 mmHg) in the ALPI group (P < 0.001) and by 6.1 mmHg (95% CI, 5.1-7.1 mmHg) in the medication group (P < 0.001). A failure rate of 30.0% was noted in the ALPI group compared with 7.5% in the medication group (P = 0.01). No treatment-related complications were recorded in either group.. After 1 year, ALPI was associated with higher failure rates and lower IOP reduction compared with PGA therapy in eyes with persistent appositional angle closure and raised IOP after LI.

Selective laser trabeculoplasty (SLT) should be explored as a therapeutic option in eyes with angle closure.. To assess the intraocular pressure (IOP)-lowering efficacy of SLT in eyes with primary angle closure (PAC) and PAC glaucoma (PACG).. Randomized clinical trial at tertiary eye care institutions of 100 patients diagnosed as having PAC or PAC glaucoma in which the angles had opened at least 180° (visible posterior trabecular meshwork on gonioscopy) after laser iridotomy. Recruitment and baseline were completed from June 2009 to April 2012 and 6-month follow-up was completed from December 2009 to November 2012.. Eligible patients with a baseline IOP greater than 21 mm Hg were randomized to either SLT or prostaglandin analog (PGA; travoprost, 0.004%). The SLT was repeated if the IOP reduction was less than 20.0% from baseline at the 1- or 3-month follow-up visit.. The primary outcome measure was the change in IOP from baseline to the final follow-up visit (at 6 months). The frequency of additional postoperative treatments and complications were secondary outcomes.. Fifty patients (96 eyes) were randomized to SLT and 50 patients (99 eyes) to PGA medical therapy. At 6 months, 49 patients in the SLT group and 47 in the PGA group completed follow-up. Analysis was based on intent to treat. At 6 months, IOP decreased by 4.0 mm Hg (95% CI, 3.2-4.8) in the SLT group (P < .001) and by 4.2 mm Hg (95% CI, 3.5-4.9) in the PGA group (P < .001). There were no differences between the SLT and PGA groups in the absolute mean reduction of IOP (4.0 vs 4.2 mm Hg, respectively; P = .78) or in the percentage of reduction in IOP (16.9% vs 18.5%, respectively; P = .52). Complete success (IOP ≤21 mm Hg without medications) was achieved in 60.0% eyes of the SLT group, compared with 84.0% of eyes in the PGA group (P = .008). No patients required glaucoma surgery. Additional medications were required in 22.0% of patients in the SLT group compared with 8.0% in the PGA group (P = .05). One patient in the SLT group (2.0%) had a transient posttreatment IOP spike greater than 5 mm Hg. The mean endothelial cell count showed a significant decrease from baseline in the SLT arm (4.8% decrease; P = .001). No other events such as persistent uveitis or increase in peripheral anterior synechiae were noted in eyes that underwent SLT. Two patients in the PGA group exited owing to drug-related complications (1 patient with uveitis and 1 with allergic conjunctivitis).. Eyes with PAC or PACG respond to SLT in the short term, but the overall long-term therapeutic effectiveness needs further evaluation.. clinicaltrials.gov Identifier: NCT01004900.

To compare the intraocular pressure (IOP) lowering effect of 0.004% travoprost and 2% carteolol in patients with ocular hypertension (OHT) after laser peripheral iridotomy (LPI) or trabeculectomy in primary angle-closure glaucoma (PACG).. Clinical case control trial. 52 consecutive PACG patients (52 eyes) with IOP > 21 mm Hg (1 mm Hg = 0.133 kPa) after LPI or trabeculectomy were enrolled. 24 patients received topical application of 0.004% travoprost (once daily) and 28 received 2% carteolol (twice daily). IOP lowering effect of travoprost and carteolol before and after treatment was measured by Goldmann tonometer and compared using t-test. The relationship of IOP lowering effect and the degree of angle open was performed by gonioscope and analyzed using Spearman rank correlation.. Compared with pre-treatment, the IOP was significantly reduced in 24 patients (24 eyes) in 0.004% travoprost group [pre-treatment: (24.67 ± 3.08) mm Hg, post-treatment: (18.58 ± 2.71) mm Hg; t = 6.600, P < 0.05], while significantly reduced in 28 patients (28 eyes) received 2% carteolol [pre-treatment: (23.57 ± 1.60) mm Hg, post-treatment: (19.57 ± 1.60) mm Hg; t = 5.130, P < 0.05]. 0.004% travoprost group is more significant in both quantity and percentage of IOP lowering than 2% carteolol (t = 2.533, 2.532; P < 0.05). There was no correlation between the IOP lowering effect and the degree of angle open in both groups (0.004% travoprost r = 0.145, 0.009; P > 0.05; 2% carteolol r = 0.090, 0.183, P > 0.05).. Both of 0.004% travoprost and 2% carteolol reduce IOP in patients with OHT after LPI or trabeculectomy in PACG. 0.004% travoprost is more effective than 2% carteolol in IOP lowering. However, the decrease of IOP is not acted through the alteration of anterior chamber angle in both study groups.

To examine the intraocular pressure-lowering efficacy and safety of travoprost 0.004% and pilocarpine 1% in Chinese patients with primary angle-closure (PAC) and primary angle-closure glaucoma (PACG) after laser iridotomy in China.. Thirty patients with PAC or PACG after laser iridotomy were randomized into this double-masked, parallel-group study. Qualified patients had a mean intraocular pressure (IOP) between 21 and 35 mm Hg; inclusive at 9 AM at eligibility visit and previously undergone laser peripheral iridotomy at least 30 days before screening visit. Patients were treated with travoprost 0.004% once daily or pilocarpine 1% 4 times daily for 12 weeks after appropriate washout of glaucoma medications. Efficacy and safety evaluations were conducted at weeks 4, 8, and 12. IOP measurements were performed at 9 AM and 4 PM at baseline and week 12 visits, except at the weeks 4 and 8, when the IOP measurement was undertaken respectively at 9 AM or 4 PM only. The degree and distribution of peripheral anterior synechiae was evaluated by gonioscopy at baseline and week 12, respectively.. Both the treatment groups showed statistically significant IOP reductions from baseline, except for the results of pilocarpine group at 4 PM in week 12. Travoprost demonstrated a statistically superior IOP reduction (7.6 mm Hg) compared with pilocarpine (1.9 mm Hg; P=0.04) at 4 PM over the 12-week period. There was no difference in peripheral anterior synechiae degree and distribution in week 12 from baseline for both treatment groups. No serious adverse event was found in both the groups.. Travoprost 0.004% once daily provides effective IOP-lowering efficacy with significantly greater IOP reduction from baseline when compared with pilocarpine 1% 4 times daily at 4 PM over the 12-week period. Travoprost 0.004% once daily is safe and well tolerated in PAC or PACG patients.

The aim of this study was to compare the intraocular pressure (IOP)-lowering effect of latanoprost and travoprost as primary therapy in patients with chronic angle-closure glaucoma (CACG) after peripheral iridotomy.. Seventy-three (73) CACG patients with IOP>19 mmHg after peripheral iridotomy and without previous antiglaucoma medication were consecutively recruited. CACG was defined as the presence of chronically elevated IOP, glaucomatous optic neuropathy, and a corresponding visual field defect in eyes with occludable angle and peripheral anterior synechiae on gonioscopy. Patients were randomly assigned to 2 groups, based on daily treatment with either latanoprost 0.005% or travoprost 0.004% in the evening for 12 weeks. The IOP was measured at 9 AM and 4 PM at baseline and at 4, 8, and 12 weeks. Between-group differences in mean diurnal IOP and IOP reduction were analyzed.. After 12 weeks of treatment, mean IOP for both the latanoprost and travoprost groups was significantly reduced, when compared to the baseline IOP (from 21.3+/-1.8 mmHg to 16.0+/-2.3 mmHg and 21.7+/-1.7 to 16.7+/-2.2 mmHg; P<0.001 for both). There was no significant difference in IOP reduction between the 2 treatment groups (P=0.19). At 4 and 8 weeks, the IOP changes from the baseline were statistically significant at all time points for both drugs (all P<0.001).. Both latanoprost and travoprost significantly reduced IOP in our sample of CACG patients after peripheral iridotomy.

To assess patient adherence and behaviors with topical once-daily therapy for glaucoma.. Prospective, observational cohort study.. One hundred ninety-six patients with glaucoma who were being treated with a prostaglandin analog in 1 or both eyes at the Scheie or Wilmer Eye Institutes between August 2006 and June 2007.. Detailed medical history was obtained from each patient. All subjects used the Travatan Dosing Aid (DA; Alcon, Fort Worth, TX) to administer travoprost as prescribed. Devices were collected at 3 months and the data of drop usage was downloaded using software provided with the dosing aid. Data were analyzed for the 8-week period starting 2 weeks after the enrollment visit and ending 2 weeks before the 3-month visit.. Assessment of adherence and patterns of drop usage as indicated by the DA.. A total of 282 subjects consented to be in the study and 86 (30%) withdrew before study completion or had device errors, leaving 196 subjects (70%) with evaluable data at 3 months. The overall mean (+/-standard deviation) adherence rate was 0.71 (+/-0.24), ranging from 0.02 to 0.97. One hundred nine of these patients (55.6%) took greater than 75% of the expected doses. Those with adherence of less than 50% of expected doses showed substantially increased dose taking immediately after the office visit and just before the return visit at 3 months (P = 0.03). The mean adherence rate estimates of the physician and patient self-report were 0.77 and 0.95, respectively. The agreement between the physician assessment and DA-recorded adherence rate showed poor correlation for individual cases (intraclass correlation coefficient, 0.09; 95% confidence interval, 0.00-0.19).. Nearly 45% of patients using an electronic monitoring device who knew they were being monitored and were provided free medication used their drops less than 75% of the time. Patients reported far higher medication use than their actual behavior. The ability of the physician to identify which persons are poorly adherent from their self-report or from other subjective clues is poor..

To report three cases of delayed choroidal detachment after treatment with topical prostaglandin analogs.. Intervention three case reports. Four eyes of three patients with chronic angle closure glaucoma developed choroidal detachment after using topical prostaglandin analogs.. Three patients with chronic angle closure glaucoma developed chroidal detachment in one week, three weeks and two years after using travoprost, bimatoprost and latanoprost respectively. All of them resolved after discontinuation of these medications. All of the eyes that developed chroidal detachment were pseudophakic.. Travoprost, bimatoprost and latanoprost may lead to choroidal detachment and hypotony. Pseudophakic patients may be at high risk of the development of chroidal detachment. Topical prostaglandin analogs should be used cautiously in these patients.
