<s>[INST] Hi, my nine month old daughter has recently been diagnosed with intermittent exotropia in both eyes which is alternating. The frequency of deviation is extremely high and the angle is approx 40 prisms. It seems to have progressed as well in the one month since diagnosis and now she has poor control over it. She is slightly far sighted (+1) and has slight astigmatism but the doctors are saying she does not need glasses at the moment. They are recommending surgery before 2 yrs of age. She has been reaching milestones on time and currently crawls and can stand up on her own. Is surgery recommended in such a young age? Are there any other options for treatment (glasses or vision therapy)? What is the success rate of eye muscle surgery? Does surgery restore depth perception/binocular vision? Will she need a repeat surgery? What is the ideal age for surgery? [/INST] Thanks for asking I have gone through question. Your 9-month-old daughter is suffering form intermittent exotrapia.
