I had 20/20 vision my whole life, until about a year and a half ago. I am near sighted, I have an oblique astigmatism, and I have steep corneas. This whole bunch of eye problems could lead to keratoconus and I think it is because my vision keeps getting worse. I now see 20/70 with the glasses that let me see 20/20 in January. Has anyone else had or currently have keratoconus? Even if you just know someone who has I’d like to talk to them. I'm 19, I can barley drive at night do to crazy light distortions, I'm almost half way to legally blind and it keeps getting worse and my mom and doctor aren't helping me feel any better about this.

It is a little unusual to see someone with stable vision until about 18 or 19 and then have a significant shift into near sightedness. This does not necessaryily mean you have keratoconus but it is worth looking into. The best way to decide whether you do or don't have keratoconus is by having a corneal topography done. Keratoconus tends to cause a pretty characteristic corneal topography. Usually, you will have a marked steepening of the cornea that tends to be located more inferiorly and will be associated with thinning of the cornea in the steepened area. So have your doctor check your corneal topography and also assess you corneal thickness. Hope all goes well.
