Article Sections. Eyelid problems range from benign, self-resolving processes to malignant, possibly metastatic, tumors. Inflammation, infection, benign and malignant tumors, and structural problems such as ectropion, entropion and blepharoptosis may occur. Fortunately, most eyelid disorders are not vision-threatening or life-threatening; however, many cause irritative symptoms such as burning, foreign-body sensation or pain.
Disease Entity [edit | edit source]. A drooping eyelid is called ptosis or blepharoptosis. In ptosis, the upper eyelid falls to a position that is lower than normal. In severe cases of ptosis, the drooping eyelid can cover part or all of the pupil and interfere with vision, resulting in amblyopia.tosis may be present at birth, or may be acquired later in life. If a droopy eyelid is present at birth or within the first year of life, the condition is called congenital ptosis. In most cases of congenital ptosis, the problem is isolated and does not affect the vision.
