Introduction: In this study, we present the demographic features and results of strabismus surgery in adult patients with various etiologies.

Methods: The records of patients that are older than 18 years and underwent strabismus surgery from January 2012 to June 2017 were evaluated. Demographic features of the patients, main complaints, diagnosis and surgical procedures as well as preoperative and postoperative ophthalmological findings including; visual acuity, distance and near deviation, sensory and motor fusion were recorded.

Results: There were 119 patients with a median follow up of 50 (3-144) months. Mean age at the time of admission was 32 (18-71) years. Ninety-five (79, 8%) patients had strabismus diagnosis from childhood.  Seventy (58.8%) patients had diagnosis of exotropia, 26 (21.8%) esotropia, 20 (16.9%) cranial nerve palsies.  When stereopsis was evaluated, 33 patients (27.8%) had improved stereopsis after surgery and 26 patients (21.8%) had no change. Stereopsis couldn’t be measured in 60 patients (50.4%) because of low vision and lack of cooperation. Preoperatively diplopia was the main complaint in 9 patients and this was corrected in 88.9% of them (8 patients) however diplopia developed postoperatively in 1 patient.

Discussion: Strabismus surgery can be performed for providing binocularity and improving cosmesis in childhood and adulthood. Strabismus surgery in adults can increase the quality of life by correcting diplopia and regaining stereopsis. Our study showed that stereopsis can be achieved in adulthood.

Conclusion: Binocularity can be improved by strabismus surgery in adult patients.
