Choroidal Thickness Change in Response to Physiological and Refractive Changes

Automatic Measurements of Choroidal Thickness Change in Response to Physiological and Refractive Changes

There is a great need for precise and repeatable measurements of the choroidal thickness. Including the diurnal physiological changes, accommodation and refractive error impact on those measurements.

Inclusion Criteria:

• participants with refractive error
• willing and able to understand and sign an informed consent form

Exclusion Criteria:

• patient unable to participate in the study
• any disease that causes visual opacity of optic media that unable to perform OCT scanning
• current enrolment in another clinical trial/research project
