prognosis good with surgical correction if no amblyopia; counsel regarding risks of strab surgery (sebsequent misalignment)
mgmt of congenital ET
-if accomodative (>+2D), full correction. If straight in distance and ET at near, 2.5D executive bifocal
-if amblyopia, patch (start w 2hrs/day while engaged)
