wow. there could be a bunch of reasons why a person would have constant tearing. here are the most
commonCommon cold:
1) DRYNESS: this woulds weird, but a clinically dry/dessicated cornea will
tearTears again
Tears again gel drops
Tears again night & day
Tears naturale
Tears naturale forte
Tears naturale free
Tears naturale ii
Tears naturale pm
Tears plus
Tears renew
Tears renewed all the time. if the surface gets dry, the nerves send a signal to the brain to turn on the lacrimal gland. the problem is that that type of "emergency" tear response is not the "right" type of tears...they're too watery and evaporate too quickly, which starts the process over. the "fix" is to change the physiology of the tear film by either using oral omega-3 fish oil supplement or fish oil artificial tears like "SOOTHE". dryness is the number 1 reason for extra tearing.
2) blepharitis: chronic eyelid staph infection. i assume this is why someone put you on steroid/antibiotic combos. before you took those Rx eyedrops, were your EYELIDS red right behind your eyelashes?
3) punctum problems including stenosis and entropion/ectropion: stenosis is when the hole is too small. IMO this is a rare cause for dryness. entropion or ectropion is when the punctum or "hole" faces the wrong way. VERY COMMON especially in people over 40.
this is a tough case, but how long did you try the patanol? topical antihistamines are known to slow/stop the tear response of the lacrimal gland.
