The small eye should not cause a problem for the snake at all. I have a Pinstripe female that I hatched last year that has a very tiny eye on one side, and a normal eye on the other. She is a little over 1000 grams now, and happens to be one of the nicest snakes I own.
Lastly, I would like to ask Steve why he is so certain that this problem is a "Genetic" defect? I have hatched out plenty of Pinstripes from my male, and only produced the one female with a small eye. Matter of fact, none of the other pinstripes in the clutch (nor the lemon blasts in the clutch) had a small eye. It may be a deformity, but I would definitely not call it genetic.
