Highlighted Findings and Recommendations for Care
Strabismus in adults has profound negative effects on quality of life and many aspects of day-to-day function. Strabismus surgery very often improves quality of life and function, and there are instruments to assess these aspects of evaluation and treatment. Patients with diplopia tend to have greatest improvements in functional domains, and nondiplopic patients tend to have greatest improvements in psychosocial domains.
Recessions of the restricted muscles are the mainstay of surgical correction in thyroid eye disease. Resection is generally avoided in restrictive disease out of concern for further reducing ductions and operating on a rectus muscle that would be best spared to provid ciliary artery supply to the anterior segment. However, it can be a useful adjunct in select cases, particularly when extremely large recessions have not fully corrected the alignment.
Screening for a history of childhood amblyopia or strabismus, checking spectacles for prism, and performing a cycloplegic refraction and cover testing are recommended for all patients undergoing refractive or cataract suregery, especially for those patients for whom monovision is planned. Patients with a history of childhood strabismus and suppresion are particularly at risk for developing fixation switch diplopia. This form of diplopia results when the previously nondominant eye becomes the dominant eye as a result of intended or unintended monovision by refractive manipulation or cataract surgery. A trial of monovision with contact lenses is prudent prior to corneal or lenticular refractive surgery to determine whether surgically induced monovision will result in new-onset diplopia. The development of asymmetric vision loss from other common diseases such as macular degeneration, myopia with axial elongation in the previously dominant eye, or diabetic retinopathy when the nondominant eye is left with better acuity may also result in fixation switch diplopia.
