A four-month-old male infant was seen with evidence of very poor vision in both eyes.  The infant reacted to light only.  Birth weight was 3020 g (nearly 7 lbs) and the pregnancy and delivery were unremarkable.  The child is otherwise healthy and the external eyes are normal in appearance.  There is no family history of serious eye disease apparent from birth.

1.	The appearance of the patient’s retina has the following features:
	a. an appearance similar to retinopathy of prematurity b. vitreous traction c. lack of vascularization in the periphery d.  evidence of exudates in and under the retina e. all of the above
2.	After examining the infant, which of the following would you do first:
	a. examine the retina of the parents b. perform an emergency vitrectomy c. do a blood test for worm infestation d.  tap the anterior chamber e. laser the base of the stalk before more retina detaches
3.	Given the fact that the birth weight was normal, the parents' retinas appear normal, the patient is affected bilaterally, and no other abnormalities nor evidence of inflammation exists, the diagnosis would be:
	a. atypical retinopathy of prematurity b. Norries disease c. Coats' disease d.  familial exudative vitreoretinopathy e. none of the above
