The patient’s eyes have become smaller, which may be caused by ptosis, swelling of the eyes, and ingrown eyeballs. 1. Ptosis: With aging, the patient’s eyelid skin relaxes or the ptosis is caused by the palsy of the motor nerve, because the eyelid fissure is small, the patient’s appearance can appear to have smaller eyes, not really smaller eyes. 2. Swelling of the eyes: Bacterial infection of the eyelid tissue causes blepharitis, or due to the long-term accumulation of secretions from the levator ani, resulting in cysts of the levator gland, the patient may appear to have a swollen eyelid, so the patient appears to have smaller eyes. 3. Sunken eyes: Acquired atrophy of the eyeball, reduction of orbital fat, fracture of the orbital wall and other causes lead to sunken eyes, so patients appear to have smaller eyes. It is recommended that patients with small eyes and other discomforts should consult the doctor in time to evaluate their condition and follow the doctor’s instructions for treatment.
