About this study
Official title: Corneal-Compensated Intraocular Pressure, Corneal Hysteresis and Corneal Resistance Factor Measurements Performed With the Ocular Response Analyzer and Their Correlation to Conventional Goldmann Applanation Tonometry.
The aim of the present study is to compare intraocular pressure (IOP) values assessed with Ocular Response Analyzer to the classical gold standard of IOP measurement, to Goldmann applanation tonometry by mucopolysacchyridosis-, Fabry-patients and healthy controls. We want to investigate biomechanical characteristics of the cornea and their influence on the IOP-measurements.

Questions about this trial
What is this clinical trial studying?
An observational study of Mucopolysaccharidosis and Fabry Disease, run by Johannes Gutenberg University Mainz at 1 site in Germany.
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 6 inclusion and 3 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 1 Mar 2013. 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 Germany. 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?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
agreement between ccIOP and GAT in MPS, Fabry and healthy controls (time frame: Sep 2013 (anticipated)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01695161, which also lists 1 linked publication.
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 1 Mar 2013; AzTrials last refreshed its copy on 8 Nov 2026.
