Patient's question:
The baby is 7 and a half months old. Recently, they have been blinking their eyes frequently. Some people say it's due to a vitamin deficiency. I want to ask what are the symptoms of a vitamin deficiency in babies? What kind of assistance is needed: The baby is 7 and a half months old,...Doctor's answer:
Blinking is a normal physiological response that helps to thoroughly remove foreign objects from the eyes and lubricate the cornea. However, if a child blinks too frequently, it is not normal. It is generally associated with the following conditions:Trichiasis (inverted eyelashes): Children often experience this when their nasal area has not fully developed, causing the skin near the inner lower eyelid to be pulled upward. This pushes a small portion of the eyelashes inward, sweeping them across the cornea, which is called trichiasis. When inverted eyelashes irritate the cornea, it can cause frequent blinking. This type of blinking usually does not harm the cornea and will often resolve on its own as the body grows.
Corneal inflammation: Corneal inflammation can also lead to blinking, often caused by viral infections such as herpes keratitis. This type of frequent blinking occurs suddenly and may be accompanied by symptoms like redness, tearing, and photophobia. This eye condition can disappear quickly with timely treatment.
