Previous eye surgery or trauma can also lead to ptosis. Eyelid lesions involve a large variety of conditions ranging from styes to malignant cancer. Your doctor should be notified for any new, enlarging, or changing lid lesion. Ophthalmologists will often work with dermatologists and pathologists when caring for eyelid lesions. They look for patterns which may suggest malignancy, both within the lesion, and along the surrounding tissues.
Viruses can also cause skin lesions around the eyes.
Eyelid lesions can also cause eyelid malpositions like those described above. What a patient reports to their doctor is critical, since they need to know why you have chosen to come in for an evaluation. Your doctor will evaluate skin around your eyes, your eyelids, and the surface of the eyeball. A test of tear production may be done, and photographs are often taken. If an eyelid problem is suspected to be causing vision problems, you may be asked to return for a visual field test.
