People using these steroid sprays like Nasonex and Flonase risk destroying their vision.  Not only are they implicated in the formation of cataracts, but also in an even more potentially serious condition: central serous retinopathy.  This is a blister that forms beneath the retina, separating it from the underlying cells that provide its nutrition and essentially killing a region of it.  This has been a known side effect of corticosteroids for many years, but these products inexcusably still lack warnings about it.

You'll see old literature describing CSR as strictly ideopathic (cause unknown) and often ascribing it to "type-A" people.  That's an outdated and lazy analysis, because it ignores the fact that this condition can produce subtle visual degradation that is only noticed by people who already have good vision and are perceptive enough to detect any change to it.  Furthermore, the victim must be persistent enough to pursue an accurate diagnosis; this may not be easy, given widespread ignorance of the problem and the need to see specialists.

Don't destroy your vision by snorting dangerous substances.
