For upper eyelid oedema, if there are other symptoms in the eye, such as redness and swelling, it is advisable to register for an eye examination first.
If the eye only shows puffiness with no other symptoms and is more pronounced in the early morning, you can first register for a nephrology examination to clarify the cause. If the examination reveals that the disease is from another department, you can also be referred to the appropriate department again for treatment.
