Question
The opening time of a newborn’s right eye is later than that of the left eye, and it remains smaller than the left eye. Is this a case of congenital eyelid ptosis, and what is the incidence rate of this disease?
Answer
Congenital eyelid ptosis is characterized by one eye being larger than the other, with common symptoms including insufficient or inability to elevate the upper eyelid, requiring the use of the forehead muscles to lift the eyelids, leading to tightness of the forehead skin and elevated eyebrows. Severe cases may also involve tilting the head upwards to see objects, presenting a special upward gaze posture. Unilateral eyelid ptosis can lead to amblyopia due to the long-term covering of the pupil. No hereditary factors across generations have been discovered, and the population incidence rate is 0.04143%. If concerned, it is recommended to seek a diagnosis at a regular ophthalmology hospital.
