Effect of High-Dose Prednisolone (Solu Dacortin®) Treatment on Choroidal and Optic Nerve Head Blood Flow in Humans
Study Details
Study Description
Brief Summary
Because of their antiinflamatory effects, glucocorticoids are often used to reduce edema in neurologic tissue and to otherwise mitigate the consequences of neural inflammation. For example, high dose prednisolone treatment has been shown to be an effective therapy for different eye diseases including severe Graves´ Ophthalmopathy and acute optic neuritis. However, contradictory results exists for the influence of high dose prednisolone therapy per se on tissue blood flow. Thus, in the current study, we plan to investigate the effect of high dose, short time therapy with intravenous prednisolone in patients with optic neuritis and severe Graves´ Ophthalmopathy.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Men and women aged between 19 and 65 years, nonsmokers
-
Group A: Patients with Graves´ Ophthalmopathy (moderate to severe and active ophthalmopathy; i.e. clinical activity score >3 or =3) suitable for high-dose treatment with prednisolone as assessed by an independent ophthalmologist
-
Group B: Patients with acute onset of optic neuritis suitable for high-dose treatment with prednisolone suitable for high-dose treatment with prednisolone as assessed by the ophthalmologist
