Introduction: This study aimed to determine the incidence and characteristics of strabismus following congenital cataract surgery in infants.
Methods: Patients aged<12 months who underwent surgery for congenital cataract and were followed-up for >/=1 years were included.Patients that had strabismus prior to surgery were excluded.Data regarding gender, cataract laterality, age at the time of surgery, ocular motility postsurgery, and the presence of nystagmus, best corrected visual acuity(BCVA),development amblyopia and aphakic glaucoma, posterior capsular opacification formation were retrospectively received from the patients’ records.
Results: 78 patients who had congenital cataract surgery were identified (47 male, 31 female).Unilateral surgery was performed in 25 patients, versus bilateral surgery in 53 of the patients.Strabismus did not occur post-operatively in 38(48.5%) of the patients (group 2),whereas 40(51.5%)(group 1) developed strabismus following surgery.The patients in group 1 were followed-up for a mean 76.58±26.72 months, versus 77.39±33 months in group 2.Mean age at the time of surgery and best corrected visual acuity were similar. Unilateral cases were more prone to develop strabismus(p<0.05).Additional ocular surgery in group 1 which was statistically significant(p<0.05).Age at the time of cataract surgery, gender, the occurrence of aphakic glaucoma, the presence of nystagmus, were not significantly associated with the development of strabismus.
Discussion: Based on the results of this study, we would recommend long-term follow-up to monitor the development of strabismus is required in all infants undergoing cataract surgery, especially unilateral cases.
Conclusion: In the present study strabismus occurred in more of the patients that underwent unilateral surgery.
