About this study
The objective of this research program is to improve diagnosis and treatment monitoring of ophthalmic disease by improving diagnostic ultrasound techniques. The program explores the use of novel signal and imaging processing techniques towards this end.
Read the detailed description
This study involves the diagnosis of several eye diseases, as follows:
Glaucoma:
- Morphometry and spectral parameter assays: Clinical correlative studies in primary and secondary glaucoma subgroups: This is a volunteer study to obtain volumetric measurements of age-related changes in the ciliary body and individual ciliary muscle components. The study will provide baseline values for treatment monitoring studies of glaucoma therapeutics. There is minimal risk that the ultrasound procedure may reveal an occult ocular disease process, but the probability is very small. Patients will be informed and assisted in obtaining appropriate care if any abnormality is seen.
- Morphometry and spectral parameter assays: Ciliary body drug interactions in patients with initial diagnosis of open angle glaucoma: This study will attempt to document changes in anterior segment functional anatomy related to medical management of glaucoma. We hypothesize that several classes of anti-glaucoma drugs produce permanent modification of ciliary muscle vasculature that is related in turn to loss of drug efficacy over time. Data from COAG patients will be compared with age and sex matched normals. Participation in the study will not effect the ongoing glaucoma therapy of patients. Accommodation:
- Accommodative function in young emmetropes and transitional presbyopes: This is a volunteer study to develop a descriptive model of the human eye's focusing mechanism based on ultrasound morphometric measurements and spectral parameter assays. This study will measure dynamic changes in ciliary body spectral assays (size, CQ2) during calibrated accommodative tasks in volunteers with good amplitude of accommodation and those with accommodative loss do to aging and model 3-D conformal changes in anterior segment structures during accommodation. There is minimal risk that the ultrasound procedure may reveal an occult ocular disease process, but the probability is very small. Patients will be informed and assisted in obtaining appropriate care if any abnormality is seen. Ocular Tumors
- Tumors of the iris and ciliary body: This is an observational study of growth pattern changes in anterior melanoma for the purpose of identifying prognostic variables associated with rapid tumor growth. A percentage of small melanomas are observed for periods of up to several years before demonstrable growth will suggest more aggressive treatment. In the clinical ultrasound practice many patients with these tumors are seen at 3 to 6 month intervals to provide the ophthalmic oncologist with updated tumor volume data. We will examine changes in the ultrasound scattering structure of these tumors over time and their correlation with volume changes. The on-going research data are not released as part of the clinical ultrasound report. Age-related Macular Degeneration
- Posterior examinations: age-related macular degeneration: This study will examine the use of higher frequency (20-30 MHz) ultrasound in the early diagnosis of Age-related macular degeneration. Our hypothesis is that early changes in the choriocapillaries and choroid vascular density and conformation can be detected with high-frequency spectral assays. We will obtain ultrasound scans at frequencies of 20 MHz or more, as well as OCT and fundus photographs. Similar numbers of age-matched control subjects will be examined. Measurements of retinal and choroidal thickness profiles in the peri-macular region will be made. Spectral data will be used for morphologic vascular analysis (size and shape). Statistical comparison will be made using parametric and non-parametric methods between control and AMD groups.

Questions about this trial
What is this clinical trial studying?
An observational study of Glaucoma and Tumors, run by Weill Medical College of Cornell University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 20 Jan 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00279695, which also lists 19 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jan 2010.
