What do these terms mean on my examination?

[Chypre]

I am getting monthly injections of Lucentis for diabetic retinopathy.  My last evaluation said:

OD cc 20/70-1PHNI
OS cc 20/30+1PHNI

I know what OD and OS means as well as 20/70 and 20/30.  What do the numbers and letters following these mean?

Happy to hear the shots help stabilize.

Less than two years ago I was

right eye:  20/400(now 20/70)
left eye:  20/200(now 20/30)

The shots are not miracle workers though.  Still can't see well enough to drive, sew, pluck my eyebrows, etc.... In bright light, like daylight, everything is white glare.  The shots have saved me from going blind, not really improved my vision.

Maybe the pinhole check is to locate light onto good parts of the retina.
To avoid confusion of the DR parts.

PS.
How are these shots working?

"c.c. without correction"

That 2nd  article doesn't cite the definition of PHNI, but it uses it in an example and  talks about testing with a pinhole. It notes: "If the acuity is not improved with a pinhole evaluation, it is likely that the cause of the decreased visual acuity is not refractive, and further opthalmologic evaluation is indicated".

It also gives examples  of the notation:
"20/40-2  ............ Missed two letters on the 20/40 line
  20/50+2............. read 2 letters on the line following the 20/50 line"

So it means that without any lens to correct your vision, those are the visual acuities. It suggests that since a pinhole doesn't improve your acuity, that there is no lens correction that would give you better visual acuity (due in this case presumably to your diabetic retinopathy).

Actually here are useful pages  for future reference that contains both abbreviations (other pages had only one or the other):
