Of 162 patients, 96 patients had binocular photophobia (60.2%). Photophobia was found to be associated with an angle of exodeviation at distance >25 Prism Diopter (Δ) (p = 0.02), and stereoacuity worse than 60 s (p = 0.02). We defined satisfactory surgical outcome as a deviation of <10 Δ. Of the 81 patients with satisfactory outcomes, 46 showed disappearance of binocular photophobia (53.5%). No factor was found to be associated with loss of binocular photophobia.
The angle of strabismus and stereoacuity were found to affect the occurrence of binocular photophobia. Successful surgery treated binocular photophobia in 53.5% of patients. Regardless of the surgical result, clinicians should educate patients in terms of the possibility of persistence of postsurgical photophobia.
