Trial summary

Low macular pigment optical density has been associated with increased risk of age-related macular degeneration, an important cause of vision problems in the elderly population. Dry eye is multifactorial disease of tears and the ocular surface associated with symptoms of dryness, grittiness, burning and redness of… Read more about this study

About this study

Low macular pigment optical density has been associated with increased risk of age-related macular degeneration, an important cause of vision problems in the elderly population. Dry eye is multifactorial disease of tears and the ocular surface associated with symptoms of dryness, grittiness, burning and redness of eyes. The risk of dry eye increases with age. The aim is to investigate the effects of sea buckthorn oil complemented with lutein on eye health, specifically on the macula.

Sea buckthorn oil & lutein, Placebo

Questions about this trial

What is this clinical trial studying?

A study testing Sea buckthorn oil & lutein in people with Risk Factors for Age Related Macular Degeneration, run by Turku University Hospital.

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 4 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 4 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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.

What does the primary outcome measure?

Change in macular pigment optical density from baseline to 6 mo (time frame: 0 mo, 3 mo, 6 mo). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Mar 2015.
