I hope this is of some help to you:
I am certain that the condition referred to as inspiratory paroxysmal
respiration, or reverse sneezing, and collapsing trachea syndrome are
totally different conditions.
However, I think that the symptoms of these conditions are very similar in
some cases, though. Especially in dogs with severe coughing episodes
associated with the tracheal collapse, which can look a lot like the
extreme inspiratory effort that is typical of reverse sneezing.
There are other reasons for confusion between these conditions. They both
occur most commonly in small breed dogs and it is likely that there are a
number of dogs who have both conditions. Tracheal collapse can be
aggravated by any other condition affecting the respiratory tract, making
it possible for a dog with reverse sneezing to develop tracheal collapse
symptoms over time.
I think that there are probably a number of causes of reverse sneezing and
that many cases occur for no discernible reason. According to the "Textbook
of Veterinary Internal Medicine" by Ettinger and Feldman, swallowing stops
attacks of reverse sneezing. This source says that reverse sneezing may be
controlled by massaging the pharyngeal area or briefly closing the dog's
nostrils. Several of my clients have mentioned that their dogs respond to
rubbing of the upper neck region, so this advice may be useful. Reverse
sneezing is a problem of the pharyngeal region.
Tracheal collapse is a problem that occurs because of improper formation of
the tracheal rings. Weakness in the tracheal rings leads to a condition in
which the trachea collapses, either during inspiration or expiration,
depending on the location of the problem in the trachea. This is highly
irritating to the dog and couging results.
Reverse sneezing tends to start at an early age and to be a persistant
problem. Tracheal collapse may cause some symptoms at an early age but in
most patients there is a gradual increase in coughing over time and it may
reach a point in which there are coughing episodes that last for several
minutes and do resemble reverse sneezing. Severe tracheal collapse symptoms
are more common in older dogs.

I would call the vet's office and ask about the eye problem.
