What you describe appears to be allergic conjunctivitis, although one cannot discount the possibility of a condition called blepharoconjunctivitis.
In allergic conjunctivitis, the eyes and eyelids become swollen, the eyes become teary and there is significant itching and sometimes pain. It is usually triggered by environmental factors such as dust or pollen. The treatment includes anti-allergy medications such as Pataday, Alrex or Optivar and cool compresses. Avoid rubbing the eyes as this will only worsen the symptoms.
In blepharoconjunctivitis, many of the above symptoms are experienced, but, in addition there will be a crustiness of the lid margins along the base of the eyelashes and you may wake up with the eyelashes stuck together, as you described. The treatment includes, washing the eyelid margins with baby shampoo to remove the crustiness and antibiotic ointment for nighttime use.
I believe the most likely diagnosis is allergic conjunctivitis. Of course, there is no substitute for a complete eye exam to confirm this. The condition is usually seasonal, but in some patients it can be present year-round if no treatment is sought.
I hope this is helpful....
No, allergic conjunctivitis can start at any time and there doesn't have to be any prior history. Ciprofloxacin is an antibiotic drop. This will have no effect on allergic conjunctivitis and only marginal effect on blepharoconjunctivitis. Ciprofloxacin ointment is much more effective for treatment of blepharoconjunctivitis. I have strong suspicion that you are experiencing allergies and this is the reason that you have not seen any improvement. I believe that the allergy drops I mentioned above may be more suitable. Of course, there is no substitute for a complete eye exam to accurately diagnose and treat whichever condition you may be suffering from.
Good Luck as you look for a resolution to this problem...
