Eyeball protrusion is divided into mild, moderate and severe. Mild eyeball protrusion is simply due to the changes in the eyelids caused by the protruding eyeballs, which can cause mild eyelid involution, eyelid eyelash inversion, or changes in the fit of the tear spot to the conjunctiva, and in some cases, uncomfortable manifestations such as grinding or dryness can occur. If the protrusion of the eyeball is further aggravated, incomplete lid closure can occur. After the eyelid can not be closed, there will be dryness of the conjunctiva in the lacrimal region, and in more severe cases, there will be corneal epithelial punctate infiltration, corneal epithelial loss, and even ulcerative keratitis. In more severe cases of protruding eyeballs there will be congestion of the eyeball and even increased orbital pressure, causing a complete failure to return the eyeball to the orbital cavity. Different treatments are available for different conditions. For example, for just a mild eye protrusion, the treatment can be replaced with ocular surface nutrient eye drops, nutrient eye ointment can be applied at night when the eyes do not close fully, and temporary lid closure can be used when exposure keratitis is caused, all taken according to the different symptoms of the protruding eyeballs. And when the protruding eyeball is particularly obvious, orbital decompression surgery can also be performed to return the eyeball to the orbital cavity.
