Strabismus is a deviation of the visual axes relative to each other and is a very common eye disease. Strabismus is not only a cosmetic disease but more importantly damage to visual acuity, binocular vision and stereopsis. There are many different strabismus forms. It is very difficult to accommodate all the different clinical forms with only one classification. Different author has different classification because of different concerns. In order to avoid clinical confusion and provide references for clinicians, literatures from mainstream domestic and international journals and new revised classification by Chinese Association for Strabismus and Pediatric Ophthalmology were reviewed in this paper.
