The posterior pole contains white lines (exposed sclera) which are concentric to the optic nerve. The edges of the lines may be
hyperpigmented due to RPE hyperplasia. There may be retinal oedema or haemorrhage due to subretinal neovascular membrane.
There may be other associated signs such as macular hole. The peripheral retina may have chorioretinal atrophy due to retinal
detachment operation. In the presence of traumatic optic neuropathy, the disc is pale.
- Look for associated anterior segment trauma such as iridodialysis, ectopia lentis or sphincter paralysis.
