In normal people, the eyes are not necessarily the same size, and slight abnormalities in size are also normal. There are many reasons for the apparent size difference of the eyes, which may be caused by pathologic factors, such as inverted eyeballs caused by congenital malformations of the orbital region or fractures of the orbital wall after trauma, which can cause the eyes to appear smaller. Ptosis, which makes the eyes look noticeably smaller. Obvious protrusion of the eyeballs and the appearance of coagulopathy, which is manifested by the obvious enlargement of the eyeballs, the common causes of which are hyperthyroidism, orbital tumors, and congenital glaucoma. Therefore, if you find that your eyes are obviously abnormal in size, go to the ophthalmology clinic of the hospital in time to find out the cause of the disease and treat the symptoms.
