If the eyelid is thicker, the muscle strength is stronger, there are adhesions and scar formation, touching the eyeball through the eyelid will also feel hard, so we should pay attention to this problem when measuring the pressure of the eye by acupressure. If the water pressure is high, the water ball will feel harder than if the water pressure is low, which is basically the reason. If the IOP is high, it must be ruled out for glaucoma, which requires optic nerve OCT and visual field, and requires regular follow-up. If glaucoma is diagnosed, it needs to be treated with IOP-lowering drugs or surgery.
