To determine whether travoprost 0.003% has a similar intraocular pressure (IOP) reduction effect to that of travoprost 0.004% while reducing side effects.
This was a prospective study from January 2018 to December 2018 that included 102 patients diagnosed with open angle glaucoma who switched from travoprost 0.004% to travoprost 0.003%. We investigated the changes in IOP, conjunctival hyperemia, corneal erosion, and eyelid pigmentation before and at 3 months after switching to travoprost 0.003%. Additionally, a questionnaire survey of these patients was conducted to determine possible side effects, including hyperemia, stinging, pruritus, irritation, blurred vision, dryness, and foreign body sensation.
IOP readings before and after switching to travoprost 0.003% were 12.95 ± 4.25 and 12.94 ± 3.89 mmHg, respectively, showing no significant change (p = 0.974). No changes were observed in corneal erosion or eyelid pigmentation; however, conjunctival hyperemia was reduced significantly from 1.60 ± 0.88 to 1.36 ± 0.84 (p = 0.001). No significant changes in hyperemia, stinging, pruritus, irritation, or foreign body sensation were reported; however, a significant improvement was noted for blurred vision and dryness (p = 0.008, p = 0.007, respectively).
We were able to show the effectiveness and safety of travoprost 0.003% as being as effective as travoprost 0.004% in reducing IOP and injections while improving blurred vision and dryness.
