A pale optic disc is a sign of atroph which can be caused by increased pressure, demyelination or external compression.

Glaucoma
External compression of the optic nerves, for example, pituitary tumour, and
Multiple sclerosis.

Question 2

thyroid eye disease

Answer 2

Radioiodine therapy can worsen thyroid-associated ophthalmopathy; patients with thyroid eye disease are generally treated with steroids for one to two weeks prior to starting radioiodine therapy.

Treatment for malignant exophthalmos is rapid administration of steroids. Where sight is threatened, orbital decompression may be necessary.
