I had ptopsis surgery in my right eye a month ago. Sometimes when I go out in the sun and while reading my eyelid still droops and obstructs my vision. The eye tends to get wet and blurs my vision. At night it gets goopy. My problem is that both my eyes have different vision. The right eye is weaker so I have to close my right eye to get better vision. I want to know whether it is a problem because of ptopsis surgery or because of my different eye vision. I am constantly putting antibiotic drops and refresh tears. I thought it might be allergies I also put all away and ate Claritin.

I have aquestion? does multiple sclerosis causing ptosis?

berryblue Sunday, February 26, 2012

I was born with ptosis of the eyelids in 1964. Both my daughter and son has ptosis pf the eyelids. My grandchild was NOT born with ptosis. Can someone tell me if ptosis is still just as prevelant for my grandchildren that have yet to be born? I had several surgeries. My last surgery was in 1980. When my children were born [1988 and the other in 1994] I did not feel that the surgical techniques for ptosis were very different from the ones performed in my childhood. Are there any breakthroughs for the correction of ptosis?

I am 26 years old and I have ptosis on the left eye since birth, it was completely shut close, couldn't open it. I have had many surgerys since 6 months old to correct it and this has managed to open my lid half way, but still very noticable. My question is....if I have children, would I pass this to my children?
