A child was brought to see you with a vague history of one eye not looking right.  The mother cannot be more specific than to say the eyes just did not look the same.  On direct questioning the mother did say that she took a photograph of her child and one eye had a “whitish” glare.  The little girl is now two years old. There is no family history of eye problems other than reading glasses and her growth and development has been normal.  Her eyes are aligned and she seems to see well with either eye.  The pupils react normally and the anterior segment looks normal.  After dilating the eyes you see the view shown in the picture above in the right eye.  The left eye appears normal.  This is the only child of young parents.

1.	The most likely diagnosis is:
	a. Coats' disease b. Eales' disease c. retinal detachment d.  retinoblastoma
2.	Although you are reasonably sure of the diagnosis, you do a CAT scan. You are specifically looking for:
	a. calcium in the globe b. bony erosion c. optic nerve abnormality d.  sinus involvement e. none of the above
3.	A careful study of the retina reveals just one lesion. The family would like to have another child.  What is the chance of their next child being similarly affected?
	a. less than 1% b. 5% c. 10% d.  45% e. none of the above
