Method for determining structural progression of eye disease and device thereof

A device for determining structural progression of an eye disease, the device comprising:

• a processor;
• and
• a memory electrically connected to the processor,
• wherein, when the processor is executed, the memory stores instructions for:
• obtaining a first-nth ocular image, which is an nth first ocular image for a user (where n is a natural number),
• obtaining a second-nth ocular image, which is an nth second ocular image for the user,
• combining the first-nth ocular image and the second-nth ocular image according to a preset method to generate an nth combined image, and
• generating an nth eye disease image for the user by using the nth combined image and a preset prone area image,
• wherein the first-nth ocular image is an ocular image of the user's optic disc,
• wherein the second-nth ocular image is an ocular image of the user's macula, and
• wherein the preset prone area image includes a first area corresponding to the optic disc, a second area where optic nerve damage is observed in the optic disc, and a third area where the optic nerve damage is observed in the macular area.
