This study will investigate the effects of lowering intraocular pressure by oral intake of Cordyceps cicadae mycelia, to provide evidence-based data for high intraocular pressure relief.

Study purpose This study investigated the effeicacy of oral Cordyceps cicadae mycelia for the relief of high intraocular pressure.

Subjects

1. The total recruitment of subjects is 60 people, aged between 20 to 75 years.
2. Subjects with intraocular pressure more than or equal to 21 mmHg are included, irrespective of whether on us of Taflotan (saflutan).

Methods

1. Informed consents will be obtained from subjects first. The subjects with pre-test intraocular pressure over or equal 21 mm Hg are advised to orally take two capsules containing a total of 500 mg of Cordyceps cicadae mycelia. After 90 minutes, the subjects are evaluated for intraocular pressure.

The pre-test and and post-intake intraocualr pressure and blood pressure data will be compared by paired t test for significant differences if any.

Inclusion Criteria:

1. Age between 20 and 75 years old, regardless of gender.
2. Pre-test confirmation of high intraocular pressure.
3. Subjects should understand the trial and agree to join the project.

Exclusion Criteria:

1. Age under 20 or over 75 years.
2. Use intraocular pressure lowering drugs other than Taflotan (saflutan).
3. Using beta-blockers or diuretics.
4. Being pregnant.
5. Disabled individuals with specific diseases or malfunction, for example tumours at terminal stage, blindness.
6. Loss of self-consciousness and behavioral capacity.
