A multicenter, retrospective chart review study comparing index therapy change rates in open-angle glaucoma or ocular hypertension patients newly treated with latanoprost or travoprost-Z monotherapy

Comparison of the effectiveness and safety of travoprost and latanoprost for the management of open-angle glaucoma given as an evening dose

As intraocular pressure (IOP) is primarily higher in the morning, an evening dose of prostaglandin analogs is typically used as monotherapy to decrease IOP in patients with open-angle glaucoma. Travoprost (TV) has reported efficacy in treating open-angle glaucoma; however, the safety and efficacy may be different compared with that for latanoprost (LT). The aim of the present study was to compare the effectiveness and safety of an evening dose of TV compared with that of LT in treating open-angle glaucoma. Data including IOP, results of lid and slit-lamp examination and ophthalmoscopy, as well as adverse effects in 250 affected eyes from patients with open-angle glaucoma who received either TV (n=89) or LT (n=161) once in the evening for 3-months were included in the analyses. At the end of treatment, TV (23.45±1.52 vs. 19.15±1.01 mmHg; P<0.0001) and LT (23.93±2.11 vs. 19.45±1.11 mmHg; P<0.0001) successfully lowered the IOP. In addition, there was no significant difference in the reduction of IOP values at the end of treatment between the two groups (P=0.120). Furthermore, there were no adverse effects on visual acuity (P>0.05), except for non-visual acuity, for example hyperemia (P<0.0001 for both groups), while there was a significant increase in the number of patients with dry eyes receiving TV (P=0.020) and a significant increase with eyelid swelling (P=0.036) and headache (P=0.037) in patients receiving LT. In conclusion, evening doses of TV and LT had the same efficacy and manageable adverse effects in the treatment of open-angle glaucoma (level of evidence, 3).

The Effects of Latanoprost With Benzalkonium Chloride Versus Travoprost With SofZia on the Ocular Surface

PURPOSE

To assess ocular surface changes in participants using latanoprost with benzalkonium chloride (Xalatan) and travoprost with SofZia (Travatan Z).

METHODS

In this prospective, open-label, nonrandomized cohort study, participants were classified into two groups: group 1 (n=28) naive to glaucoma therapy, group 2 (n=27) on previous Xalatan monotherapy in both eyes. Both groups started (or continued) Xalatan in the right eye and Travatan Z in the left eye. Baseline, 1-, and 2-month measurements of tear breakup time (TBUT), corneal staining score, conjunctival staining score, conjunctival hyperemia score, tear production, and intraocular pressure were obtained. The Ocular Surface Disease Index questionnaire measured participants' comfort and dryness symptoms. Medication preference was recorded.

RESULTS

Data were collected from 55 participants. Tear breakup time at baseline and 1-month follow-up in group 1 was significantly longer than that of group 2 (P=0.005). At 2 months, there was no significant difference in TBUT between the two groups (P=0.779). Tear production in group 1 at all three time points was significantly higher than group 2 (P<0.05). Conjunctival staining score at 2 months in group 1 was significantly higher than group 2 (P=0.031). There was no significant difference in other parameters between the groups at any other time point. No significant difference in any parameter was found between Xalatan and Travatan Z (intragroup comparison).

CONCLUSIONS

Significant differences in ocular surface characteristics were detected between groups, but no significant difference was detected between participants treated with Xalatan and Travatan Z.
