Work in Progress - Self Portraits

I've been working on a series of self-portraits recently, drawing mostly, with the intention of doing some paintings as well. They are portraits of my right eye, which I noticed looked different to the other one, and also different to how it used to look before the retina damage which has made it lose central vision. It looks 'blown', with a darker and larger pupil and isn't focussing - as if its desperately seeking for more information. At first (and perhaps still) it looked frightened, and to me it expressed the fear and pain I had experienced. I felt that it had 'looked into the abyss'. In the drawings I am trying to capture both the physical change, and also to express some of the fear and loss. 

An early and further development of the same drawing from life...

This drawing is a double self portrait. in the background a drawing from a photograph i took in  a mirror - not long after I came out of hospital. in the foreground a portrait from life 8 months later.

The woman in the photo looked raw, thin faced, with a fearful look in her right eye. I wanted to document any changes since then. This idea will probably form the basis of a painting.
