Question

I recenly completed my C&P exam for Keratoconus a week ago. I was diagnosed in Septer of 2013, with Kerotoconus. During my entrance med exam, my vision was 20/20 in both eys. About 2 years into my service, I started seeing double, and bluriness. I made an appt with the eye doc in 29 stumps, and was diagnosed with asigmatism. At the time of that exam I was 20/40 in my left eye and 20/20 in my right eye. I had two ofher eye exams while in, and while I do not remember what my visual acuity was My perscriptions changed again. During the second exam a

Keratometry was performed. Here are the notes from previous eye exams.

I didn't go back for any eye exams until 2013, due to lack of money or vision insurance. I just dealt with the double vision and bluriness. Finally I found out I could get my eyes checked through the VA since I was alred 20% service connected for flat feet and my knee, and made an appt. That was when I was given the diagnosis of Keratoconus. I am in the process of getting a contact to help correct my vision, though the C&P doc said I would probably be better off getting the corneal transplant. I applied for service connection in November 2014, and am awaiting the decision. I wanted to know what the board thinks of it being granted since from my perspective, it started during my time in service and was never diagnosed until my visit in 2013. Thanks for any help in this.

I am including the relevant notes from the exam below if anyone can make sense of them.

"Describe the history (including onset and course) of the Veteran's
current
eye condition(s) (brief summary): history of astigmatism. No one used the
word "keratoconus" while in the service. Never turned down for
refractive
surgery. Dx of keratoconus first used at VA in 2013. No family history
Last eye exam at VA by Mar 27, 2015. Patient not dilated at this visit.

[X] Yes [ ] No
If yes, describe the impact of each of the Veteran's eye
condition(s),
providing one or more examples: poor vision in left eye: Unable to do
work
involving fine depth perception
2. Remarks, if any: The question is asked if the patient has keratoconus
that
is as least as likely as not incurred in or caused by double vision or
blurred vision during service.
Keratoconus is a degeneration of the cornea which leads to distortion and
thinning of the front of the eye. As a result, the cornea steepens (this is
measured by keratometry or corneal topography)
Keratoconus is not caused by blurred vision or double vision. It is instead
a
degeneration. Review of the STR reveals no diagnosis of keratoconus. The
three refractions done over the course of three years were consistent.
Keratoconus patients will often fluctuate. Keratometry done in 1998 was not
indicative of keratoconus. The cover test done at the visit with the
complaint of double vision revealed no motion and no further workup.
At Mr. Mayer-Tucker's first visit to the Cheyenne VA in Sep 2013, he
reported
monocular double vision (overlapping images in one eye) and that he had
good
vision with previous glasses. The exam previous to that had been three years
earlier.
