A thorough external examination is also necessary to evaluate possible external causes including ptosis, lid hemangiomas, or other lesions that could lead to impairment of visual development. However, these methods have not yet shown to provide an additional benefit to vision or stereoacuity when compared to patching and spectacle use [24-27]. Main Outcome Measures.
