Patient: My mother said congenital! No information ever! The left and right eyes are the same size! Jia Renbing, Ophthalmology Department, Shanghai Ninth People’s Hospital: According to what you said, it should be a congenital ptosis of the left eye. This condition can only be treated by surgery, and in general, the emphasis is on the completion of surgery before school age, and relatively few like your age have not been treated yet. After surgery, both eyes are basically the same size and no significant difference can be seen. We have to complete several hundred such surgeries here every year, and the number of surgeries is the first in China. If you want to be treated, I suggest you might want to come over for surgery while you are on vacation, and the cost is around 2,500-3,000 yuan. If you have any questions, you are welcome to leave a message or contact me directly. Jia Renbing, Ophthalmology, Ninth People’s Hospital, Shanghai Jiaotong University School of Medicine
