Thank you so much for your response. I just spent 300 dollars taking my 10 year old daughter to the ophthalmologist!! I will look at old photos tho, and research this Homer's Syndrome. I wonder if the optometrist, looked for the dilation lag/constriction in the pupil that you spoke about.
A droopy eyelid could mean many things. Sometimes it is congenital and may progress with age. Looking back at old photos may help in determining this. Other times, it could be a sign of something more serious. I have been just diagnosed with Horner's Syndrome and the key findings include a droopy eye and dilation lag/constriction in the pupil of the same eye (as a result of damage to the nerve path that controls the muscles responsible for those things). Horner's Syndrome could be the result of something serious and I'm getting worked up for it now. You should make an appointment with your ophthalmologist to make sure everything is OK.
