Orbit Surgery clinical trials

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.

NCT ID: NCT00347282 Completed - Clinical trials for Postoperative Complications

Post Enucleation Socket Syndrome Study

Start date: March 2006
Phase: N/A
Study type: Observational

Superior sulcus deformity in post-enucleation socket syndrome (PESS) may pose a significant cosmetic blemish after enucleation surgery despite apparently adequate orbital volume replacement. The underlying reasons include the lack of accurate pre-operative volumetric assessment of the anophthalmic socket, leading to either under or over estimation of the orbital implant required and the shifting in orbital and periocular structures that may occur post enucleation. Conventional imaging studies (computed tomography and magnetic resonance imaging) have been used to study the anatomy of anophthalmic sockets, but there are several drawbacks such as poor image quality for detailed volumetric assessment, long exposure time with possible motion artifact and etc. The new multi-detector computed tomographic technology is the latest advance in diagnostic radiology that allows rapid high resolution images to be obtained for three dimensional reconstruction and volumetric assessment. This new imaging modality will contribute greatly to the understanding of PESS and the surgical planning of anophthalmic sockets reconstruction. This is a pilot study aiming to collect clinical data on the volumetric and structural changes in PESS. The information obtained will: 1. allow more accurate volume estimation of the primary orbital implants prior to enucleation surgeries, thus minimize the development of PESS; 2. evaluate the volumetric & structural anomalies that constitute PESS 3. be used for the development of a new customized secondary orbital implant to manage superior sulcus deformity in PESS.
