What Causes Lazy Eye? 13 Causes To Consider

Drooping Eyelid or Ptosis

One or both eyes may turn inward, outward, upward, or downward in children with lazy eyes. Depending on the severity of the condition, it may occur intermittently or all the time. In many cases, a lazy eye is usually caused by drooping eyelids. The eyelid may exhibit minor drooping, while the eyelid may cover the entire eye in some instances. Ptosis affects one or both eyes. Due to the drooping of eyelids, ptosis can limit vision or even block it completely. 

Ptosis may also occur with a lazy eye as the same nerve stimulates both. Over time, these conditions can lead to poor vision. Fortunately, there are many ways to treat ptosis. Doctors may perform frontalis suspension surgery, which utilizes silicone or Mersilene mesh as the sling material. The sling-type material creates a connection between the eyebrow and eyelid margin, elevating the eyelids more effectively. In the case of acquired ptosis secondary to a neurogenic and traumatic event, patients are advised to wait up to 12 months before surgery to facilitate spontaneous recovery or improved eyelid function.
