Question 3: Describe the above optic nerve head photos.
Answer:
The optic disc photographs show some asymmetry. Both nerves are of an average size. The right optic nerve shows a generalised enlargement of the optic cup, with a cup-to-disc ratio of approximately 0.8, with temporal peripapillary atrophy. There is no focal loss (notching) of rim tissue, although the neuroretinal rim is thin both superiorly and inferiorly. There is no disc haemorrhage.
The left optic nerve shows focal thinning of the rim inferiorly, with an inferior notch. There is also thinning of the neuroretinal rim superiorly, although there is no notch in this region. The cup-to-disc ratio is approximately 0.9, and there is temporal peripapillary atrophy. There is no optic disc haemorrhage.
