Steroid Eyedrop Adherence After Trabeculectomy

Status Completed

Clinical Trial Summary

The study will monitor how often persons use eye drops that are prescribed after glaucoma surgery and will compare the adherence with drop use to the success rate of the surgery.

Clinical Trial Description

Trabeculectomy is the most common operation performed for all forms of glaucoma. The procedure depends upon appropriately modulated healing of the conjunctiva and sclera, a major component of which is delivery of frequent topical corticosteroid eye drops (prednisolone acetate 1%) by the patient, initially every 2 hours when awake for 1-2 weeks, then in tapering frequency over the 6 weeks after surgery. While the initial success of trabeculectomy at one year varies from 55-80% depending upon the criteria chosen to measure outcome, improvements in success would benefit hundreds of thousands of patients in the USA yearly. There is reasonable evidence that steroid drops benefit success, but there is essentially no data on how successfully patients remember to take the drops. In previous research, investigators have shown that glaucoma patients take only half to two-thirds of prescribed drops. An electronic monitoring device is now available that can fit the eye drop bottle used in steroid drops, accurately measuring the time and date of each drop taken. The investigators can further assess the accuracy with which each patient can deliver a drop from the bottle being monitored in a clinic session directly onto the eye's surface by observing their performance. The proposal's hypothesis is that the one year success rate of the procedure will be related to the adherence to steroid drop taking by patients. The outcome will have two important benefits. First, if adherence is less than ideal (which is very likely), then those with greater adherence will have more successful surgery, confirming that steroid treatment is effective. This has only been measured once, 30 years ago, at a time when trabeculectomy was being performed quite differently. If steroid treatment is not related to success, a change in preferred practice patterns is in order. If steroid treatment is related to success and adherence is variable, the investigation will have proven means to increase adherence through reminder systems, which have shown in past randomized clinical trial to be effective. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
