My father is glaucoma, already blind. Excuse me doctor, how to return a responsibility ah

Glaucoma is a common malignant eye disease in ophthalmology, mainly caused by intermittent or continuous increase in intraocular pressure. Because of the continuous intermittent or continuous increase in intraocular pressure, it will cause certain damage to the eyeball and other eye tissues and visual functions. If it is not treated for a long time, it will lead to loss of vision and blindness.
