About

Choroidal thickness represents blood-flowing of eyes. The investigators detect the choroidal thickness of the young participant using SD-OCT to see the effect of Resveratrol Based Nutritional Supplement on Choroidal Thickness.

Full description

34 young, healthy participants were included in this study; They were randomly divided into two groups by age and gender matched.100 mg Longevinex® capsule was given to the study group and 100mg placebo capsule to the control group. All participants underwent OCT scanning with spectral domain optic coherence tomography (SD-OCT) at baseline and 1 h following Longevinex® or placebo administration. The choroidal thickness was measured manually by the Heidelberg Eye explore software(version 5.3.3.0, Heidelberg Engineering) with a vertical line to the retinal pigment epithelial layer.

Enrollment: 34 estimated patients

Sex: All

Ages: 23 to 28 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Male and female patients 23-28 years of age. nonsmokers.

2. Participation in another simultaneous medical investigation or trial Renal failure requiring dialysis or renal transplant or liver dysfunction History of other disease,or other findings giving reasonable suspicion of a disease or condition that contraindicates the use an investigational drug, might affect interpretation of the results of the study, or render the subject at high risk from treatment complications.
3. IOP over 30 mmHg.
4. Any previous retinal laser photocoagulation to the study eye in treatment naive. Any previous intravitreal injection in study eye (triamcinolone or other) in treatment naive.
5. Any previous vitrectomy in study eye (posterior or anterior associated with vitreous loss in cataract surgery).
6. Intracapsular cataract extraction (posterior capsule needs to be present).
7. Aphakia or absence of the posterior capsule in the study eye, Structural damage to the center of the macula in the study eye preexisting to CRVO likely to preclude improvement in visual acuity following the resolution of macular edema, including atrophy of the retinal pigment epithelium, subretinal fibrosis, laser scar(s).
