True eyelid ptosis is when the upper eyelid muscle weakens and the eyelid comes down further on the pupil. This occurs very uncommonly. This is from Botox injected into the muscles around the eye socket diffusing into the upper eyelid.
What is more common is brow drooping or ptosis. This can be avoided or predicted in most patients. Treating the forehead lines relaxes the frontalis muscle that raises the forehead. Many patients already have overhanging eyelids or low eyebrows. They habitually hold their brows up with the frontalis muscle to relive the heaviness. If the frontalis is treated with Botox, this compensation is eliminated.
Some patients can even get a browlift with properly placed Botox. As stated above, you should seek out a skilled, well trained physician for Botox treatments.
