Detailed Description

Enroll 60 eyes with posttrabeculectomy glaucoma (30 eyes with posttrabeculectomy residual primary angle-closure glaucoma. 30 eyes with posttrabeculectomy residual primary open angle glaucoma). Inclusive at 9 AM at eligibility visit and previously undergone trabeculectomy at least 30 days before screening visit. Qualified patients had a mean intraocular pressure (IOP) between 21 and 35mm Hg. All patients had documented residual PACG/POAG after trabeculectomy, with inadequate IOP control in at least one eye.The right eye was selected if both eyes showed about the same IOP. The previous IOP-lowering drugs were washed out before using tafluprost. Because all of the eyes had critical IOP levels, the design of this study was open-label, with emphasis on IOP change. Both patients in PACG and POAG groups will dose 1 time daily in each eye for 6 months. Each eye will be preformed tafluprost 0.0015% at 9 PM.The investigator monitored compliance via review of bottles at each follow-up visit, and at the last visit the old bottles will be returned and the investigator will keep them for storage. Efficacy and safety evaluations will be conducted at months 1, 2, 3, 4, 5, and 6 after the start of tafluprost treatment.The IOP will be measured at 1, 2, 3, 4, 5, and 6 month visit. All IOP measurements are to be performed at about the same time of day (at 9 AM at each visit). IOP was measured by Goldmann tonometer. The IOP value was the mean of 3 consecutive measurements.A visual field examination with automated perimetry(Octopus 101) using a threshold program was performed at the screening visit. If the visual field examination has been carried out within 12 weeks before the screening visit, no additional visual filed examination is required at the screening visit. A visual field examination and RNFL(retina nerve fiber layer) examination are to be performed at screening and the last visit respectively by the same technician with the same protocol. Topical examination by slit lamp is to be performed to evaluate the anterior segment. Ophthalmoscope examinations will be performed at screening and the last visit to examine the vitreous body, retina, and optic nervehead.The efficacy of tafluprost therapy is to be evaluated by comparing the baseline IOP and the IOP at various intervals after the start of treatment, by ANOVA test. The comparison of two groups was estimated by t test. The difference of the time point IOP between the 2 groups was analyzed by X2 test.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
IOP
Time Frame: 6 months
The IOP will be measured at 1, 2, 3, 4, 5, and 6 month visit. All IOP measurements are to be performed at about the same time of day (at 9 AM at each visit). After topical anesthesia and conjunctiva sac stained byfluorescence, IOP was measured by Goldmann tonometer. The IOP value was the mean of 3 consecutive measurements.
