This preliminary assessment of the ocular surface of patients with concomitant strabismus before surgery was undertaken to determine if the presence of strabismus increases the risk of dry eye disease. This was a cross-sectional study of 204 patients with concomitant strabismus and 125 healthy volunteers. Group 1 comprised 135 exotropias; Group 2, 70 esotropias; and Group 3, healthy volunteers. Ocular redness index was significantly different for exotropia vs. esotropia with a higher index in temporal bulbar conjunctiva for esotropia. There were no other significant findings. The results indicate that strabismus does not affect tear film stability with ages of up to 30 years and, thus, does not increase risk of dry eye disease.
No risk of dry eye disease in concomitant strabismus cases
