Children with one or two eyes, one large and one small, are usually suffering from ptosis and should be treated according to the cause of the ptosis. Ptosis can be caused by viral infections, trauma, or congenital developmental abnormalities. Children need to go to the ophthalmology department of the hospital to have the cause clarified and be treated under the guidance of the doctor. For ptosis caused by eye trauma or viral infection that affects the function of the motoneuron, it can be treated with neurotrophic drugs to promote the recovery of the motoneuron function, thus improving the patient’s appearance, such as oral methylcobalamin tablets. The medication should be used according to the doctor’s prescription. For ptosis caused by congenital developmental abnormalities or other types of ptosis that cannot be improved by conservative treatment, ptosis can be treated by ptosis corrective surgery, commonly used surgical methods include levator palpebral muscle shortening, frontalis muscle suspension, and so on. If you are experiencing discomfort, it is important to go to the ophthalmologist at the hospital to have the cause identified and then have the doctor direct you to take the appropriate treatment.
