Hi,
Just wanna let you know about the following I just read on wikipedia about the active ingredient in Rinexin:
 In the United States, PPA is no longer sold due to an increased risk of haemorrhagic stroke.[12] In a few countries in Europe, however, it is still available either by prescription or sometimes over-the-counter. In Canada, it was withdrawn from the market on 31 May 2001.[13] It was voluntarily withdrawn from the Australian market by July 2001.[14] In India, human use of PPA and its formulations was banned on 10 February 2011,[15] but the ban was overturned by the judiciary in September 2011.[16]^
You probably already knew that, but anyway, be careful! 🙂
Also interesting from that article is that the drug is dopaminergic - it acts on the central nervous system. So it might be helping your eyes in a way that is totally unrelated to your nose/sinusitis.
Also I'd like to ask: have you tried some other decongestant meds, such as xylometazoline or tramazoline? They cannot be used long term (this leads to rebound congestion), but I'm considering them for cases when I have an eye crisis.
