Ptosis. Is my case due to muscle weakness or excessive skin?

[Maisatomai]

I have drooping eyelid and my dad has drooping eyelid too.

I once went to a eye doctor and he said mine is not serious and refused to operate on it.

But I realized it getting more and more serious and unsightly. Is my case due to muscle weakness or excessive skin and is it true mine is not a serious case and I should not operate on it

Your picture looks like an Asian eyelid.  There are racial differences in the structure of the eyelids (as well as the structure of the eye i.e. angle closure glaucoma much more common in Asians and Eskimos, macular degeneration much less common in blacks, etc.)  

While I cannot see the level of your left upper lid it looks like this is more skin than lid. You would need to see an oculoplastic surgeon one that is familiar with the correction of lid problems in eyes shaped like this. If the lid skin is blocking your field of vision and causing symptoms its possible your insurance might help you with surgical correction. Since this runs in your family and you have had it a long time it likely doesn't require all the diagnositic tests for things like myasthenia gravis or Horner's Syndrome in sudden onset true ptosis.
