This results in an overproduction of tears and eye watering. When your eyes are dry, your brain sends a signal to the lacrimal gland, which is responsible for producing tears. When the eyelid is unable to close completely or frequently, it can cause the eyes to dry out and become irritated. Dry or watery eyesĮyelids are responsible for protecting the eyeball from dirt and debris, as well as keeping it moist. This is due to the failure of the nerves and muscles in charge of opening/closing the eyes to work together. If ptosis is caused by a neurological disorder that affects nerves or muscles of the eye, like myasthenia gravis, the ability to close or blink the eye(s) may be limited. Muscles within the eyelids also can fatigue if they are working extra hard to lift a droopy eyelid. This is due to the extra work surrounding muscles do to compensate for a drooping eyelid.Įyebrows may stay raised to try and lift the eyelid, resulting in exhaustion of forehead muscles. It’s common for people with ptosis to experience fatigue around their eyes and forehead. If ptosis is beginning to affect your ability to see, we recommend visiting your eye doctor to discuss possible solutions. Over time, this compensation can cause head and neck problems. When the eyelid has sagged to the point where it is beginning to block/cover the pupil, individuals will often tilt their heads back in order to see clearly. This symptom is seen in severe cases of ptosis. It’s also possible for children with congenital ptosis to have double or blurred vision due to astigmatism, a common refractive error. Normally individuals who have crossed eyes experience double vision due to the misalignment. The muscles of the eye are closely related, so when an eye disorder is present that affects the eyelid, it’s very common for the eyeball to be affected as well, though not guaranteed.ĭouble vision is a symptom that somewhat relies on having crossed eyes. This has to do with the fact that the cranial nerve responsible for eyelid movement is also responsible for eye alignment, movement, tracking and focus. Having crossed or misaligned eyes ( strabismus) is commonly associated with ptosis. However, it’s important to monitor any changes in the eyelid(s) or development of new symptoms. If the difference is very slight and you experience no other symptoms, this could be a result of fatigue and may resolve on its own. Typically, individuals will observe that one eye is more open than the other or that one eyelid appears lower than the other. If you notice the symptoms listed below in yourself, it’s possible that you have ptosis: Drooping eyelidsĭrooping of the upper eyelids is the most common symptom recognized in ptosis. Ptosis can also affect one or both eyes and be ever present or come and go. Symptoms of ptosis can be very mild and unnoticeable, or severe. While the symptoms of ptosis may seem pretty straightforward - it is in the title, after all - symptoms experienced in addition to a droopy eyelid could help indicate the source of the issue. doi:10.1371/ is a condition characterized by the drooping of the upper eyelid.
