Objective: To investigate the effects of two different medical treatment options on choroidal thickness (CT) in cases of open-angle glaucoma (OAG).

Methods: Sixty-seven eyes newly diagnosed with OAG and 52 healthy eyes constituting the control group were included in the study. Glaucomatous eyes were randomly divided into two subgroups; Group I was started on bimatoprost 0.03% and Group II on a brinzolamide 1.0%/timolol maleate 0.5% fixed combination (BTFC). Intraocular pressure (IOP), ocular pulse amplitude (OPA) and subfoveal CT measurements were performed in all eyes in the study before treatment and on weeks 2, 4 and 8 after treatment.

Results: Mean initial IOP values in groups I and II and the control group were 25.5?±?4.7, 25.1?±?5.2 and 16.1?±?2.9?mmHg, mean OPA values were 3.7?±?1, 3.6?±?1.4 and 2.4?±?0.6?mmHg and mean CT values were 269.4?±?83, 264.5?±?84.4 and 320.1?±?56.6?μm, respectively. Eight weeks after treatment, mean IOP values in Groups I and II and the control group were 18.3?±?2.6, 18.1?±?3.4 and 15.7?±?2.9?mmHg, mean OPA values were 2.9?±?1.2, 2.8?±?1.5 and 2.3?±?0.8?mmHg and mean CT values were 290.2?±?87.3, 271.8?±?82.5 and 319.3?±?56.8?μm, respectively. No significant difference was determined in terms of the decrease in IOP and OPA obtained after treatment in Group I and Group II. However, a significant difference was observed between the two groups in terms of choroidal thickening after treatment.

Conclusion: The use of topical ocular hypotensive medication in eyes with OAG results in an increase in CT. This increase is relatively greater with bimatoprost 0.03% therapy compared to BTFC.  相似文献

ABSTRACT

Objective: To compare the intraocular pressurelowering efficacy and safety of topical bimatoprost 0.03% with that of travoprost 0.004% for the reatment of black patients with open-angle glaucoma (OAG) and ocular hypertension (OHT).

Research design and methods: Multicenter, prospective, randomized, investigator-masked trial of 94 black patients previously diagnosed with OAG or OHT. All patients completed washout of ocular hypotensive medications before study participation. Patients were assigned to either once-daily bimatoprost 0.03% or once-daily travoprost 0.004% for 3 months.

Main outcome measures: The primary outcome measures were mean intraocular pressure (IOP), mean change from baseline IOP, and percentage of patients who reached a target IOP reduction. Secondary measures included ophthalmologic examination and adverse events.

Results: Both bimatoprost and travoprost significantly lowered IOP at all study visits (?p < 0.001). Bimatoprost provided mean IOP reductions from baseline that ranged from 6.8?mmHg to 7.8?mmHg (27% to 31%). Travoprost provided mean IOP reductions from baseline that ranged from 6.2?mmHg to 6.9?mmHg (25% to 28%). By month 3, 85% of participants in the bimatoprost group had a mean IOP reduction of at least 20%, compared with 68% of those in the travoprost group. Furthermore, 31.9% of those in the bimatoprost group had a mean IOP reduction of more than 40% at month 3 compared with 20.9% of those in the travoprost group. There were no significant differences in biomicroscopy, ophthalmoscopy, or visual acuity. Ocular redness was the most commonly reported adverse event in both treatment groups. No serious adverse events were reported.

Conclusions: Bimatoprost and travoprost each effectively lowered IOP in this population of black patients. More patients achieved clinically relevant IOP reductions with bimatoprost.  相似文献

SUMMARY

Purpose: To analyse a response to the therapy switch from the concomitant application of β-blocker and topical carbonic anhydrase inhibitor to the fixed combination of timolol and dorzolamide (Cosopt*) in glaucoma/ocular hypertensive patients under everyday, office-practice conditions.

Patients and methods: The data source was a survey among practising ophthalmologists in Switzerland assessing their experience with glaucoma patients/ocular hypertensives put for the first time on the fixed combination of timolol and dorzolamide. A total of 98 patients underwent the therapy switch in at least one eye. The intraocular pressure (IOP) change between the baseline visit before switch to the timolol-dorzolamide fixed combination occurred, and the first follow-up control after the switch, served as an indicator of compliance.

Results: The IOP decreased on average from 19.43?±?5.64?mmHg to 17.97?±?3.58?mmHg (p?<?0.01). The time to the follow-up visit ranged from 4 to 354 days, and the magnitude of IOP change demonstrated a significant dependence on the time to the follow-up visit, also when corrected for baseline IOP level. A total of 87 (85.3%) continued on the timolol-dorzolamide fixed combination therapy after the first control visit. In 68 of these 98 patients the contralateral eyes underwent the same therapy switch, and their IOP followed an identical pattern of behaviour.

Conclusion: The average I OP decrease of 1.5?mmHg upon therapy switch to the timolol-dorzolamide fixed combination suggests a better efficacy due to improved compliance. Short-term compliance benefit seems to be more pronounced. The high timolol-dorzolamide fixed combination therapy continuation rate reflects an improvement in compliance and subjectively-perceived convenience.  相似文献

Purpose: To assess the long-term intraocular pressure (IOP) changes after the intravitreal injection of bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA) for treatment of age-related macular degeneration (AMD) and diabetic macular edema (DME) patients and evaluate the correlation factors.

Material and methods: Patients with neovascular AMD or DME underwent treat-and-extended anti-VEGF regimen in one eye and followed more than 12 months were enrolled in this study. We set three criteria of IOP elevation: (1) the IOP of the treated eye increased above the contralateral eye for at least two consecutive visits; (2) the IOP of the treated eye increased above the pre-injection IOP for at least two consecutive visits; (3) and the IOP of the treated eye increased more than 5?mmHg above the baseline IOP for at least two consecutive visits. We used mixed model univariate and multivariate analysis to assess the association between IOP elevation and independent parameters including age, sex, lens status, the number of injections, and underlying disease.

Results: In total 152 patients, 83 patients with AMD and 69 patients with DME, were included in this study. Mean follow-up time was 18.7 months, with a maximum of 50 months. In IOP elevation, 54 eyes (35.6%) showed an IOP increase above that of the contralateral eye (criteria 1), 50 eyes (33.4%) showed an IOP increase above the baseline IOP (criteria 2), and an IOP increase greater than 5?mmHg above the baseline IOP observed in nine eyes (5.9%) (criteria 3). In the univariate analysis, lens status and total number of injections were statistically significant for criteria 2 and 3 (all ps?<?0.05). However, in the multivariable analysis, only the number of intravitreal injections was statistically correlated with sustained IOP elevation for criteria 2 and 3 (p?<?0.001 and p?=?0.039, respectively).

Conclusions: Our results suggest that under long-term monitoring, with a treat-and-extended regimen, intravitreal bevacizumab injections were associated with sustained IOP elevation. In particular, multiple intravitreal injections could be associated with sustained IOP elevation.  相似文献

ABSTRACT

Objective: To investigate the effect of selective laser trabeculoplasty (SLT) on the intraocular pressure (IOP) of untreated fellow eyes in patients with open-angle glaucoma.

Study design: Retrospective chart review.

Patients and methods: Charts of all patients who underwent SLT at the University of Texas Southwestern Medical Center at Dallas between September 2003 and May 2006 were reviewed. Each patient had IOP measurements by Goldmann applanation tonometry in both eyes preoperatively, and at 1 hour, 2 weeks, 3 months, and 6 months postoperatively. Patient age, gender, diagnosis, central corneal thickness (CCT), previous intraocular surgeries, and degrees of laser treatment were tabulated for each patient. Patients with a history of previous glaucoma surgery in either eye were excluded as were those who underwent any change in glaucoma medications or further laser or surgical intervention in either eye within 6 months of SLT. Data were analyzed using a paired two-tailed t-test, an unpaired two-tailed t-test, ANOVA, and linear regression.

Results: A total of 43 patients were included through 6 months of follow-up. Mean reduction in IOP in the treated eye was 3.9?±?0.6?mmHg or 18.8% (p?<?0.001) at final exam. Mean IOP reduction in the fellow untreated eye was 2.1?±?0.5?mmHg or 11.2% (p?<?0.01). Patients with higher preoperative IOPs had a greater reduction in IOP in both eyes (p?<?0.001 for treated eyes, and p?=?0.02 for untreated eyes). Patients who were on a larger number of glaucoma medications preoperatively had a greater response in both eyes (treated eye p?=?0.002, untreated eye p?=?0.008). There was no significant difference in IOP response in either eye based on age, gender, CCT, degrees of treatment, or phakic status.

Conclusions: SLT produces a sustained and statistically significant IOP reduction in the fellow untreated eyes of patients with open-angle glaucoma. The results of our study support a biological mechanism of action for SLT. Limitations of this study include its retrospective design, relatively small sample size, a possible effect of increased compliance with medical therapy following SLT, and an inherent bias of excluding patients who underwent a change in medications or further laser or surgical therapy during the period under review.  相似文献

ABSTRACT

Aims: To assess the incremental change in intraocular pressure (IOP) levels in patients with primary open-angle glaucoma or ocular hypertension, insufficiently treated with topical ocular hypotensive monotherapy or combination therapy and changed to the latanoprost/timolol fixed-combination therapy (LTFC).

Methods: The glaucoma database of the Glasgow Royal Infirmary was reviewed retrospectively to identify patients ≥?18 years of age with primary open-angle glaucoma or ocular hypertension in at least one eye who had been switched to LTFC from a previous monotherapy or combination therapy. Ninety patients were identified, and 59 (66%) had changed to LTFC from latanoprost monotherapy (LM). The analysis focused on this subgroup because few patients were changed from any other single therapy. At least one documented patient visit following the change to LTFC was required. The within-subject difference in IOP levels (IOP on LM–IOP on LTFC) was calculated for each case, and the statistical significance of the mean change in IOP was analysed using a 2-sided Student's paired t-test with a 0.05 α level.

Results: The mean decrease in IOP after changing to LTFC from LM was 2.6?mmHg (95% confidence interval?=?1.6, 3.6), from 21.4 (SD?=?3.5) mmHg to 18.8 (SD?=?4.2) mmHg (p?=?0.002).

Conclusions: LTFC provides significant incremental IOP reduction in patients with primary open-angle glaucoma or ocular hypertension who require additional IOP reduction following treatment with LM.  相似文献

ABSTRACT

Objective: To investigate the influence of switching to travoprost on intraocular pressure (IOP) of chronic open-angle glaucoma (COAG) patients.

Research design and methods: Multicentre, open-label, non-comparative, 12‐week, phase IV study conducted at 10 academic and hospital centres in Hungary. Patients’ compliance to use of the pre-study medication was confirmed at a visit 10 days before the baseline measurements, and compliance was monitored throughout the study period.

Results: Of the 203 COAG patients three (1.48%) ceased travoprost medication due to ocular hyperaemia, and one subject was lost from follow-up. Self-reported compliance was optimal except for two patients. For the per-protocol analysis 197 patients were evaluable. IOP of the 37 per-protocol patients receiving additional travoprost medication decreased from 23.1 ± 3.2?mmHg (mean ± SD) to 17.3 ± 2.6?mmHg at week 12 (?p < 0.001). Switching the 121 per-protocol patients from latanoprost to travoprost IOP decrease from 20.8 ± 3.5?mmHg to 17.7 ± 2.4?mmHg (?p < 0.001). IOP of the 11 patients switched from topical non-selective beta-blockers to travoprost decreased from 20.1 ± 2.1?mmHg to 15.7 ± 1.5?mmHg (?p < 0.001). For the whole per-protocol population (n = 197) IOP decreased from 21.0 ± 3.4?mmHg to 17.4 ± 2.4?mmHg (?p < 0.001). Defining responders as having an IOP decrease > 2.0?mmHg or ≥ 5?mmHg at week 12, the responder rate was respectively 62.9% or 31% for the total study population; 86.5% or 54.1% when travoprost was added to the established therapy; 54.5% or 24.0% if latanoprost was switched to travoprost; and 90.9% or 36.4% for those who switched from beta-blockers.

Conclusion: Travoprost provided a clinically and statistically significant IOP decrease in uncontrolled COAG patients whose self-reported compliance to their previous topical medication was optimal. Our results suggest that the IOP reduction found after switching to travoprost is not explainable by improved compliance due to the clinical study situation.  相似文献

ABSTRACT

Objective: To investigate if combined intraocular pressure (IOP)-lowering medication with travoprost/timolol fixed combination and a carbonic anhydrase inhibitor, brinzolamide, is superior to both travoprost monotherapy and travoprost/timolol fixed-combination therapy in primary open-angle glaucoma and ocular hypertension.

Methods: Following a 4-week wash-out period and using 4-week long treatment periods, 20 primary open-angle glaucoma or ocular hypertension patients were treated with evening travoprost 0.004?%?, then switched to evening travoprost 0.004?%?/timolol 0.5?%?fixed combination, and finally the treatment was combined with adjunctive twice-daily brinzolamide 1?%?ophthalmic suspension. Both eyes were treated, but only one eye per patient (the eye with the higher mean diurnal IOP at baseline), was evaluated. IOP was measured at 8 a.m., 12 noon and 4 p.m. at baseline and at the end of each treatment period.

Results: Mean diurnal IOP (mean (SD)) at baseline was 28.5 (7.3) mmHg which decreased to 22.3 (6.3) mmHg on travoprost, 19.2 (3.4) mmHg on travoprost/timolol fixed combination and 17.3 (3.4) mmHg when the brinzolamide was added to the travoprost/timolol combination (ANOVA, contrast test, p?<?0.003 for all comparisons). The individual time point IOP values showed similar and significant stepwise differences.

Conclusion: Adjunctive brinzolamide medication provided further IOP decrease in patients receiving evening-dosed travoprost/timolol fixed combination. The travoprost/timolol fixed combination was significantly more effective in IOP reduction than travoprost monotherapy, which by itself induced a significant IOP decrease compared to the untreated baseline value. The results of this open label study suggest that combined therapy with travoprost/timolol fixed combination and brinzolamide is clinically useful for IOP-lowering in primary open-angle glaucoma and ocular hypertension.  相似文献

Purpose: To evaluate the potential usefulness of a freeze-dried (lyophilized) amniotic membrane transplantation with mitomycin C (MMC) in the maintenance of functioning glaucoma surgery in cases of pediatric glaucoma.

Methods: Thirty eyes of pediatric patients with glaucoma were included in this study. Trabeculectomy with amniotic membrane implantation and MMC was done in group 1 (15 eyes), and trabeculectomy with MMC only was done in group 2 (15 eyes). The preserved amniotic membrane was placed over the scleral flap and under the conjunctiva. The mean intraocular pressure (IOP) was measured pre- and postoperatively and bleb appearance was noted. The follow-up time was 18 months after surgery.

Results: The mean postoperative IOP was significantly decreased to 15?±?1?mm Hg and 17.2?±?2.9?mm Hg in the 2 groups, respectively. The bleb was functioning well in the follow-up period in most of the cases, except 5 cases that needed another surgery. Complications such as inflammation, choroidal detachment, or toxic keratopathy were not noted in group 1 but were noted in group 2.

Conclusion: Trabeculectomy with amniotic membrane transplantation and MMC can effectively control the elevated IOP in pediatric patients with glaucoma without significant postoperative complications.  相似文献

Abstract

Purpose: To compare the efficacy, safety, and potential advantages of the preservative-free versus preserved brimonidine %0.15 preparations in patients with primer open-angle glaucoma (POAG) or ocular hypertension (OHT).

Methods: Forty-two eyes of the 21 treatment-naive patients with POAG or OHT were enrolled in this study. Eyes were randomly assigned to receive brimonidine-purite 0.15% or preservative-free brimonidine 0.15% two times daily. Efficacy of the two eye drops was assessed by measuring the intraocular pressure (IOP) at 9–10 am at baseline and week 4. Safety and potential advantages of the drops were evaluated at weeks 4 in terms of ocular symptoms and tear parameters. Ocular symptom values of the patients were evaluated with a scale of 0–4 (0?=?no discomfort and 4?=?severe discomfort).

Results: Both of the brimonidine tartrate formulations resulted in statistically similar IOP reduction (preserved formulation; ?5.2?mmHg [22.9% reduction] preservative-free formulation; ?5.7?mmHg [24.1% reduction], p?=?0.37). It was found that brimonidine tartrate formulations with and without topical preservatives did not produce a statistically significant difference in pain, stinging, and blurred vision at the upon instillation (p?>?0.05). However, the burning sensation was significantly higher in the preservative-free formulation at the first instillation compared to the preserved formulation (p?=?0.01). Also, there was no statistically significant difference between the two formulations in terms of symptoms (itching, burning, tearing, stinging, and photophobia) and tear parameters during the day (p?>?0.05).

Conclusions: Although topical preservative-free brimonidine tartrate treated eyes had a more burning sensation at the first drop, the two formulations were similar in terms of ocular tolerability in the short term period. Also, both formulations were found to reduce IOP at a similar rate.  相似文献

ABSTRACT

Objective: To evaluate the intraocular pressure lowering effect of the dorzolamide/timolol fixed combination (DTFC) in non-responder glaucoma patients to prostaglandin analogs/prostamides (prostas).

Patients and methods: All glaucoma patients treated with DTFC, between June 2003 and December 2005, who were unresponsive to prostaglandin analogs/prostamides, were identified through a retrospective medical records review. A non-responder was defined as an intraocular pressure (IOP) lowering effect less than 15% compared with baseline measurement. Two 12?hour IOP diurnal curves, measured between 8:00?a.m. and 8:00?p.m. (8:00?a.m., 10:00?a.m., 12:00?noon, 2:00?p.m., 4:00?p.m., 6:00?p.m. and 8:00?p.m.), were obtained retrospectively from the records of 31 patients, the first while on prostaglandin analogs/prostamides (baseline IOP) and the second while receiving DTFC (DTFC IOP). The study outcomes were the change in mean diurnal IOP and the reduction in IOP fluctuation as a result of receiving DTFC in patients unresponsive to prostas. The IOP was evaluated by intragroup comparisons with a two-tailed paired Student's t?test. A chi-square test was adopted for analysis of categorical variables.

Results: 31 patients were included in this retrospective study. DTFC significantly reduced IOP in the patients overall, from 25.4 (3.5) to 20.2 (1.0)?mmHg, p < 0.0001. The majority of patients were diagnosed with pseudoexfoliative glaucoma (PEX) (58%; 18/31). DTFC reduced the mean IOP fluctuations over 12 hours (highest minus lowest IOP reading within the 12?hours pressure curve) from 8.6 (3.2) to 4.3 (1.4)?mmHg, p < 0.0001. The most common adverse events were ocular burning (16%) and taste perversion (13%). There were no serious treatment-related adverse events.

Conclusion: DTFC significantly reduced the IOP in patients with glaucoma who did not respond to prostaglandin analogs/prostamides. Further research is needed to confirm these results.  相似文献

ABSTRACT

Objective: At the introduction of the fixed-combination of brimonidine/timolol in Germany in 2006, a non-interventional, multicenter, observational, open-label study was initiated to evaluate efficacy, tolerability, and safety of this preparation in a broad patient population.

Methods: The study population comprised patients with bilateral primary open-angle glaucoma or ocular hypertension with insufficient intraocular pressure (IOP) control who participating physicians determined required a change of medication, and who switched to exclusive use of the new fixed-combination brimonidine 0.2%/timolol 0.5%. Patient demographics and information on specific risk factors were collected. IOP readings were recorded for each eye at treated baseline (previous therapy), 4 to 6 weeks, and 12 weeks after changing to twice-daily brimonidine/timolol. Tolerability was measured using a four-step scale ranging from excellent to poor. All adverse events were recorded.

Results: Mean treated baseline IOP (±SD) for all patients (N?=?861) was 20.8?±?3.5?mmHg. Five hundred sixty-five patients switched from monotherapy, 138 patients switched from other fixed combinations, and 158 patients had been using non-fixed combinations of up to four different active agents. The brimonidine/timolol fixed combination provided an additional IOP decrease in most pretreatment subgroups, with an overall reduction to 16.9?±?2.6?mmHg after 4 to 6 weeks and to 16.5?±?2.7?mmHg after 12 weeks. Both of these values were significantly lower than baseline IOP (p?<?0.001). A target pressure of <18?mmHg was achieved in 79.5% of all eyes at week 12. Tolerability of fixed-combination brimonidine/timolol was rated excellent or good by the physicians for 97.1% of patients, and by 93.4% of the patients themselves. Few adverse events occurred during the treatment period.

Conclusions: Although this study was limited by its observational design, our results show that the fixed combination of brimonidine 0.2%/timolol 0.5% was effective, well tolerated, and safe in a broad POAG patient population.  相似文献

ABSTRACT

Objective: To evaluate intraocular pressure (IOP)-lowering efficacy, tolerability, and safety of the fixed combination of bimatoprost 0.03% and timolol 0.5% (Ganfort?) among German patients.

Methods: Multicenter, observational, open-label study of patients with primary open angle glaucoma or ocular hypertension (n?=?606). As determined by participating physicians, patients had insufficient IOP control and required a medication change. They were switched to once-daily fixed-combination bimatoprost/timolol with no wash-out period. IOP was recorded at treated baseline, 4–6 weeks and 12 weeks after switching. Tolerability was measured using a 4-step scale (excellent, good, moderate, poor) and all adverse events were recorded.

Results: A total of 405 patients switched from monotherapy, 97 switched from other fixed combinations, and 104 switched from non-fixed combinations. Among all patients, 32.5% had used prostaglandin analog (PGA) monotherapy, 8.7% had been using a fixed combination that included a PGA, and 6.9% had been using an adjunctive combination of a PGA and a β-blocker. Mean treated baseline IOP (±SD) for all patients was 20.7?±?3.5?mmHg. Overall, changing medication to fixed-combination bimatoprost/timolol lowered IOP to 16.6?±?2.7?mmHg (p?<?0.001 vs. baseline) after 4–6 weeks and to 16.1?±?2.6?mmHg (p?<?0.001) after 12 weeks; reductions of 19.8% and 22.2%, respectively. Combined bimatoprost/timolol provided an additional IOP reduction versus baseline in most subgroups based on prior treatment. At week 12, patients who had previously used a β-blocker achieved an additional 25.8% decrease from baseline and IOP was reduced by 22.6% in former PGA monotherapy patients. At week 12, 84.6% of all eyes reached a target pressure less than or equal to 18?mmHg. Tolerability of bimatoprost/timolol was rated excellent or good by the physicians for 98.7% of patients and by 96.7% of the patients themselves. Few adverse events occurred during the treatment period.

Conclusions: Although this study was limited by its observational design, our results show that the fixed combination of bimatoprost 0.03%/timolol 0.5% was effective, well tolerated, and safe in a broad patient population.  相似文献

ABSTRACT

Objective: To compare the ef?cacy of latanoprost, bimato­prost and travoprost for lowering IOP in patients with glaucoma.

Research design and methods: In order to carry out this meta-analysis, randomized trials (2001–2004) were identi?ed on Medline and EMBASE using the following key words: glaucoma, ocular hypertension (OHT), random­ization, trial, latanoprost, bimatoprost and travoprost. The studies had to compare at least two prostaglandin analogues as mono-therapy. Cross-over experimental designs were excluded. The main outcome measure was IOP at ?nal visit. Statistical analyses included random effects, pooled estimates of treatment effects, tests for publication bias, and random-effects models to obtain adjusted treatment effects on ?nal IOP after lowering for baseline IOP, and duration of follow-up. Random effects Poisson regression models were used to estimate the adjusted effects of treatments on response rates (IOP < 18?mmHg).

Results: Nine studies were used in the analysis. Patient mean age varied from 56.7 to 68.8 years and baseline IOP ranged from 22.3 to 26.5?mmHg. Three hundred and seventy-eight patients were treated with bimatoprost, 385 with travoprost and 555 with latanoprost. Patients treated with travoprost and bimatoprost had lower IOP levels at the end of follow-up (–0.98?mmHg [95% CI: –2.08; 0.13; p = 0.08] and –1.04?mmHg [95% CI: –2.11;0.04; p = 0.06], respectively) than those treated with latanoprost. The combined effect of newer prostaglandin analogues (bimatoprost/travoprost) was an adjusted decrease of 1.00?mmHg [95% CI: –1.91;–0.10], p = 0.03], or a 17% higher adjusted response rate (Incidence Rate Ratio 1.17, 95% CI, 1.00–1.35, p = 0.04), compared to latanoprost.

Conclusion: Travoprost and bimatoprost may have greater ef?cacy in lowering IOP for patients with OHT or glaucoma.  相似文献

ABSTRACT

Purpose: The purpose of this study was to compare travoprost (TRAV; travoprost 0.004%) and the fixed-combination of dorzolamide/timolol (DTFC; dorzolamide 2.0%/timolol maleate 0.5%) ophthalmic solutions for reducing intraocular pressure (IOP) in patients with primary open-angle glaucoma (OAG) or ocular hypertension (OHT).

Methods: This was a randomized single masked, study with parallel controls. The TRAV group (n = 29) dosed once daily at 9:00 PM while the DTFC group (n = 27) dosed twice daily at 9:00 AM and 9:00 PM. IOP was measured at baseline, and following 3 weeks and 6 weeks of treatment at 8:00 AM, 12:00 PM, 4:00 PM, and 8:00 PM.

Results: Mean average IOP reductions from baseline during the course of the day were 7.5 (32.7%) and 7.1 (30.7%)?mmHg for TRAV and 4.8 (23.1%) and 4.5 (21.7%)?mmHg for DTFC at 3 weeks and 6 weeks, respectively. The greater IOP reduction for patients receiving TRAV was statistically significant at both the 3 and 6 week visits when averaged across all four time points (?p < 0.01). The two products were well-tolerated over the course of the 6 week study. Some factors such as taste perversion were reported more often in the DTFC group.

Conclusions: Travoprost monotherapy provided better efficacy in terms of IOP reduction and per-centage of IOP reduction compared to dorzolamide 2.0%/timolol maleate 0.5% fixed combination.  相似文献

Ocular carteolol (Mikelan), Teoptic, Ocupress) is a nonselective beta-adrenoceptor antagonist with intrinsic sympathomimetic activity (ISA). Ocular carteolol effectively reduces intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OH). Twice-daily administration of standard carteolol has generally similar IOP-lowering efficacy to other ocular beta-adrenoceptor antagonists such as timolol, betaxolol and metipranolol in patients with OAG or OH. In addition, long-term treatment with carteolol has similar efficacy to timolol and betaxolol in terms of reducing IOP and maintaining visual fields in patients with newly diagnosed primary OAG (POAG). The new long-acting formulation of once-daily carteolol has equivalent efficacy to the standard formulation of carteolol administered twice daily in patients with OAG or OH. Both the standard and long-acting formulations of ocular carteolol are generally well tolerated in terms of topical adverse effects involving the eyes or systemic adverse effects involving the cardiovascular system. Thus, twice-daily carteolol is a well established option in the treatment of glaucoma and OH, and the new once-daily formulation of long-acting carteolol offers similar efficacy and tolerability with a potential for improved patient adherence.  相似文献

Purpose: To evaluate the efficacy and safety of superior peripheral iridotomy versus inferior peripheral iridotomy in the treatment of primary angle-closure glaucoma (PACG) in phakic patients.

Methods: In this randomized, prospective, paired-eye comparative study, patients with primary angle closure or primary angle-closure suspects were recruited and randomized to receive neodymium-doped yttrium aluminum garnet (Nd:YAG) laser peripheral iridotomy (LPI) superiorly in one eye and inferiorly in the other eye. Patients were masked to the location of treatment in each eye. The main outcome measures were patency of iridotomy, intraocular pressure (IOP), complications and visual symptoms at each postoperative visit during a 1 year follow-up.

Results: A total of 164 patients were recruited, of whom 150 (91.46%) completed the study. The mean age was 58.85?±?6.4 years. Average IOP measurements before LPI was 22.85?±?7.53 and 23.62?±?8.32 in superior LPI and inferior LPI eyes respectively. After LPI, average IOP was 25.14?±?2.73 and 20.97?±?2.72 in superior LPI and inferior LPI eyes respectively. Inferior LPIs required less use of mean total laser energy to perforate the tissue (p?=?.05) and resulted in a significantly lower incidence of iris bleeding at the time of treatment (p?=?.004), lower IOP elevation following treatment (p?=?.002), lower incidence of focal corneal damage (p?=?.002) and a lower post-laser iritis (p?=?.04). All the 300 iridotomies were patent at 12 month follow up.

Conclusion: The inferior LPI appeared to be an efficient method of preventing pupil block with fewer complications. Visual symptoms following inferior LPI are similar to superior LPI.  相似文献
