|---|---|---|---|---|---|---|
| NCT00000170 ↗ | Occlusion Versus Pharmacologic Therapy for Moderate Amblyopia | Completed | National Eye Institute (NEI) | Phase 3 | 1999-04-01 | - To determine whether the success rate with drug treatment (atropine) of amblyopia due to strabismus or anisometropia in patients less than 7 years old is equivalent to the success rate with occlusion (patching) therapy - To develop more precise estimates of the success rates of amblyopia treatment - To identify factors that may be associated with successful treatment of amblyopia - To collect data on the course of treated amblyopia to provide more precise estimates of treatment effects than are now available Extended Follow up of Study Patients - Primary: To determine the long-term visual acuity outcome at age 10 years and at age 15 years in patients diagnosed with amblyopia before age 7 years. - Secondary: To determine whether the long-term visual acuity outcome at age 10 years and at age 15 years differs between patients who received patching followed by best clinical care and patients who received atropine followed by best clinical care |

| NCT00000333 ↗ | Evaluation of Benztropine for Cocaine Craving - 2 | Completed | Washington D.C. Veterans Affairs Medical Center | Phase 2 | 2001-05-01 | The purpose of this study is to compare the efficacy of benztropine (or DA reuptake inhibitor) with atropine and placebo in affecting stimulated craving to cocaine cues. |
| NCT00000333 ↗ | Evaluation of Benztropine for Cocaine Craving - 2 | Completed | National Institute on Drug Abuse (NIDA) | Phase 2 | 2001-05-01 | The purpose of this study is to compare the efficacy of benztropine (or DA reuptake inhibitor) with atropine and placebo in affecting stimulated craving to cocaine cues. |
| NCT00001864 ↗ | Amblyopia (Lazy Eye) Treatment Study | Completed | National Eye Institute (NEI) | Phase 3 | 1999-05-01 | The purpose of this study is to compare the results of two standard treatments for amblyopia in order to find out if one is more effective than the other. Amblyopia, which develops in childhood, is also called "lazy eye," because one eye is not being used properly. The brain favors the other eye for some reason, such as crossing or turning out of the eyes, and vision in the weak eye is reduced. Amblyopia is treated by forcing the child to use the weak eye. There are two ways to do this: 1) a patch placed over the "good" eye forces the child to use the weak eye; or 2) an eye drop placed in the "good" eye once a day to blur vision in that eye makes the child rely on the weak eye. The success rates with both of these methods have been reported to be about the same; this study will try to identify if one is more effective than the other. Children will be randomly assigned by computer to one of the following two treatment methods: Patch The child initially will wear a patch over the "good" eye for 8 to 12 hours every day. If vision in the weak eye improves, the patching time will be decreased. If vision remains good after 3 months, the patching will be stopped, unless the child's doctor believes treatment should continue. If vision in the weak eye does not improve, the patching time will be increased. Eye Drops The child will be given one drop per day of atropine in the "good" eye. If vision in the weak eye improves, the drops will be given less often. If the vision remains good after 3 months, the drops will be stopped, unless the child's doctor believes treatment should continue. If the initial daily drop does not improve the vision in the weak eye, the child's eyeglasses may be changed to try to further blur the vision in the "good" eye. After 6 months, treatment may be stopped if it has not been successful. If treatment has been successful after 6 months, it may be continued at a reduced amount or stopped. Follow-up visits will be scheduled every 4 weeks for the first 6 months and every 2 to 4 months after that until the end of the 2-year study. During each visit the eyes will be examined for eye movements and vision, and the pupils will be dilated to examine the inside of the eye. |
| NCT00094614 ↗ | Trial Comparing Daily Atropine Versus Weekend Atropine | Completed | National Eye Institute (NEI) | Phase 4 | 2002-06-01 | The goals of this study are: - To compare the visual acuity outcome in the amblyopic eye after 17 weeks of daily use of atropine versus weekend-only use of atropine. - To compare the proportion of patients achieving a complete treatment response (defined as amblyopic eye acuity >20/25 or equal to that of the sound eye in the absence of a reduction in the sound eye acuity from baseline) with daily atropine versus weekend-only atropine. |
