NCT ID: NCT06272851 Not yet recruiting - Diabetes Mellitus Clinical Trials

Measuring Choroidal Thickness Using Optical Coherence Tomography

Start date: March 15, 2024
Phase:
Study type: Observational

To compare the choroidal thickness in eyes of diabetic patients with eyes of age matched controls using optical coherence tomography.

NCT ID: NCT04255524 Not yet recruiting - Myopia, Progressive Clinical Trials

Choroidal Change on OCTA in Eyes With High Myopia

Start date: February 1, 2020
Phase: N/A
Study type: Interventional

Myopia is a global healthy concern, especially the high myopia and pathological myopia among Asian populations. However, its mechanism still remains largely unclear. Recent findings suggested choroidal changes might be related to the development of myopia. This study is to useOCT angiography (OCT-A) to investigate parapapillary choroidal microvasculature change in myopic eyes, and try to find the cause-and-effect relationship between choroidal change and the development of myopia.

NCT ID: NCT03532867 Not yet recruiting - Choroid Disease Clinical Trials

Study of Changes in Retrofoveolar Choroidal Thickness During Aerobic Exercise

MOPAS
Start date: July 2019
Phase: N/A
Study type: Interventional

Study the change of retrofoveolar choroidal thickness measured by optical coherence tomography during aerobic exercise inducing an increase in systolic blood pressure in healthy subjects.Ten healthy participants will perform an exercise (riding a bicycle ergometer) and will be examined with EDI-OCT. Each participant will be scanned before exercise, during the exercise and afterwards at 0 and 5 min. Each OCT measurement will be coupled to the arterial blood pressure evaluation.
