A number of common eye diseases such as age-related macular degeneration and glaucoma are associated with ocular perfusion abnormalities. Although this is well recognized there is not much possibility to improve blood flow to the posterior pole of the eye in these diseases. For many years, moxaverine has been used in the therapy of perfusion abnormalities in the brain, the heart and the extremities. This is based on a direct vasodilatatory effect of the drug, but also on the rheological properties of red blood cells. In two recent studies the investigators have shown that intravenous moxaverine increases choroidal and retrobulbar blood flow in healthy young subjects, in elderly people with healthy eyes and in patients with eye diseases associated with hypoperfusion. The present study aims to investigate, whether ocular blood flow is also improved after oral administration of moxaverine.

Design Details

16 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Basic Science Study

Basic science studies help researchers understand how the body works or how a disease develops. They don't test treatments, but they build the foundation for future therapies.



Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
Criteria

Any sex

Biological sex of participants that are eligible to enroll.

From 18 to 35 Years

Range of ages for which participants are eligible to join.

Healthy volunteers allowed

If individuals who are healthy and do not have the condition being studied can participate.

Criteria

Inclusion Criteria: * Men and women aged between 18 and 35 years, nonsmoker * Body mass index between 16 and 30 kg/m² * Normal findings in the medical history and physical examination unless the investigator considers an abnormality to be clinically irrelevant * Normal laboratory values unless the investigator considers an abnormality to be clinically irrelevant * Normal ophthalmic findings, ametropia \< 6 dpt, anisometropia \< 2 dpt Exclusion Criteria: * Regular use of medication, abuse of alcoholic beverages or drugs * Participation in a clinical trial in the 3 weeks preceding the study * Treatment in the previous 3 weeks with any drug * Symptoms of a clinically relevant illness in the 3 weeks before the first study day * History or presence of gastrointestinal, liver or kidney disease, or other conditions known to interfere with distribution, metabolism or excretion of the study drug * Blood donation during the previous 3 weeks * Presence of any ocular pathology that interferes with the aims of the present study * Hypersensitivity to moxaverine * Acute gastric bleeding, massive cerebral hemorrhage related to stroke * Women: pregnancy or lactation
