: To determine the clinical manifestations and risk factors of developing strabismus in primary congenital glaucoma (PCG) patients who underwent glaucoma surgery. : A retrospective case-series study of 54 PCG patients who were followed for at least 3 years after glaucoma surgery. The subjects were divided into 2 groups based on the occurrence of strabismus. Age at glaucoma diagnosis and surgery, visual acuity, intraocular pressure, amblyopia, cup-disc ratio, and orthoptic status were compared between the 2 groups. : Twenty of 54 patients (37.0%) developed strabismus after glaucoma surgery. The mean ages at the time of glaucoma diagnosis and surgery were 3.2 ± 2.7 months and 3.4 ± 2.8 months in the strabismus group and 24.3 ± 19.1 months and 26.4 ± 18.9 months in the non-strabismus group, respectively ( < .05). In addition, the mean logMAR visual acuities were 0.87 ± 0.38 in the strabismus group and 0.24 ± 0.21 in the non-strabismus group ( < .05). The proportion of patients experiencing amblyopia was 90.0% in the strabismus group. Low visual acuity and young age at glaucoma surgery were significant predictors of developing strabismus. Kaplan-Meier survival analysis demonstrated that the probability of developing strabismus after glaucoma surgery was 50.6% at 10 years post-surgery. : PCG patients who developed strabismus after glaucoma surgery were diagnosed with glaucoma and underwent surgery at a younger age, exhibited a worse mean best corrected visual acuity, and exhibited a higher amblyopia incidence than did patients in the non-strabismus group.
