The eyes are the windows to the soul, and the eyelids are the barrier that protects them. Some people with diabetes suddenly develop droopy upper eyelids after years of suffering from diabetes, so it is important to be on the lookout for articular nerve palsy. Diabetic nerve damage is a form of diabetic mononeuropathy, the incidence of which has been on the rise in recent years and deserves the attention of diabetics. Diabetes-induced cranial nerve damage is most likely to involve the oculomotor nerve, the trochlear nerve and the abducens nerve, especially the oculomotor nerve and the abducens nerve. In addition to eyelid ptosis, it is often associated with limited eye movement, such as inward, upward and downward eye movement, and exotropia and diplopia. The onset of the disease is often sudden, the patient has a positive history of diabetes, the onset is rapid, and there is often orbital or forehead pain a few days before the onset of ptosis. The pathogenesis of the disease is not well understood, but it is thought to be related to the blockage of tiny blood vessels caused by diabetes, and poor long-term glycemic control can directly affect its development. The treatment of arteriovenous nerve palsy lies in identifying the original cause and making the necessary and appropriate treatment for the cause. Since the occurrence of diabetic neuropathy is closely related to hyperglycemia, effective blood glucose control is the fundamental treatment principle. Improving the microvasculature and repairing the damaged nerve is the main treatment for actinic nerve palsy, while the use of local neurotrophic drugs facilitates the restoration of motor function to the damaged actinic nerve as soon as possible, as most obviously demonstrated by the rapid improvement of upper eyelid ptosis symptoms. In the process of actively promoting nerve repair, strabismus and binocular diplopia are also a major problem that cannot be ignored and often plague patients. At this time, we often find that the affected eye cannot turn and can only slant outward, making it difficult to see objects in front of it; although the vision of the affected eye is not significantly diminished, it becomes quite blurred when both eyes are seen together, often with double shadows, and it is easy to fall down when walking. This can seriously affect the patient’s daily life. Sometimes, even when the eye can move normally, the phenomenon of diplopia still exists, which requires our rehabilitation doctor to guide the eye movement training and visual integration training to improve the symptoms of strabismus and diplopia. Only timely treatment can help to restore the eye movement as soon as possible.
