Sorry it took me so long to get back to you...been really busy. DJ went to see Dr. Goldberg at West Reading Opthalmic Associates in Reading PA. Evidently they specialize in children's general to extreme eye care. Dr. Goldberg said he doesn't forsee any problems since the doseage DJ is on is equivalent to what the body makes naturally. I said, "That's great! That's the idea, but his Endo says we should still have him checked."
