Early and late complications after strabismus surgery in children.

Introduction: Strabismus surgery mostly is safe and effective, but both early and late complications may occur and must be diagnosed and treated to obtain the best possible surgical outcome. The aim of our study was to assess the occurrence of early and late complications after strabismus surgery in children operated on in our center in years 2020-2023.

Material and methods: In the years 2020-2023, 555 patients with strabismus aged 2 to 12 years old were operated on in our clinic. Operated patients suffered from the following types of strabismus: strabismus convergent, strabismus divergent, vertical strabismus and an strabismus with additional oblique component. The strabismus angle before surgery ranged from 17 to 52 PD. The first check-up was performed 2 weeks after the surgical procedure and the next ophthalmologic examination was performed 3 months after the surgery.

Results:  After strabismus surgery, children experienced early complications in the form of: postoperative infection (3 patients), allergic reaction (7 patients), dellen (4 patients), changes in the position of eyelids (5 patients), transient changes in refraction (4 patients). Late complications were noted in 18  patients in the form of: unsatisfactory alignment of the strabismus angle (10 patients), diplopia (2 patients), conjunctival scarring (4 patients), granuloma (2 patients).

Conclusion: Strabismus surgery in children is associated with a low number of early and late complications. Systematic postoperative follow-up is important to achieve the best possible outcome.
