Condition(s) targeted: Primary Open Angle Glaucoma; Ocular Hypertension

Intervention: Goldmann and Perkins applanation tonometry (Device); TAFLUPROST 0.0015% EYEDROPS (Drug); LATANOPROST 0.005% EYEDROPS (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Azienda Ospedaliera Spedali Civili di Brescia

Official(s) and/or principal investigator(s):
Luciano Quaranta, MD, Principal Investigator, Affiliation: Università degli Studi di Brescia

Summary

- Main objective is to compare the ability of Latanoprost 0. 005% preservative-added

ophthalmic solution versus Tafluprost 0. 0015% preservative-free ophthalmic solution, both given once a day at the evening, in reducing 24-hour intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG) and/or ocular hypertension (OHT) at first diagnosis. First efficacy variable will be the difference between mean nocturnal IOP values after three months of treatment: nocturnal IOP is defined as the mean value between 2AM and 6AM measurements.

- Secondary objectives will be the comparison between Latanoprost 0. 005% and Tafluprost

0. 0015% ophthalmic solution about:

- Mean 24-hour IOP values after three months of treatment

- IOP values at these time-points: 10AM (± 1 hour), 2PM (± 1 hour), 6PM (± 1 hour),

10PM (± 1 hour), 2AM (± 1 hour) and 6AM (± 1 hour) after three months of treatment

Clinical Details

Minimum age: 45 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

uvae, etc)

- Past ocular surgery, except cataract surgery in the previous 6 months

- Corneal abnormalities that can influence IOP measurements (corneal oedema)
