Question 1:  Describe the patients optic nerve

The right disc appears to be of normal size with a normal vascular pattern. The vertical cup:disc ratio is 0.55 to 0.6. The cup depth appears to be average depth.  The neuroretinal rim is intact 360 degrees with no evidence of  neuroretinal rim thinning or notching. There is no retinal nerve fibre layer loss an no retinal nerve fibre haemorrhage.

The left appears to be of normal size with a normal vascular pattern. The vertical cup:disc ratio is 0.8. The cup depth appears to be average depth but the photograph is over-exposed.  The neuroretinal rim shows thinning superotemporally and inferotemporally with evidence of  neuroretinal rim thinning superotemporal and inferotemporally. The retinal nerve fibre layer thinning is evidence with RNFL defect superotemporally and inferotemporally. There is  retinal nerve fibre haemorrhage.
