The purpose of the study is to conduct comparative analysis of the two types of surgical approaches used in strabismus surgery: vertical and limbal L-shaped. Material and Methods. Analysis of surgical treatment of strabismus in 137 (205 eyes) patients aged 4 to 15 years was performed. During surgery, access to the surgical field was carried out by a vertical conjunctival incision in 143 cases (69.8%), by limbal incision — in 62 cases (30.2%). Results. Duration of hyperemia and edema in the group with limbal access is significantly shorter than in the group with vertical conjunctival access (12.2±0.14 and 24.5±0.15 days, respectively) (p<0.001). Reactions to suture material in the group with limbal access were shown only in 2 cases (3.2%), and in the group with vertical access — in 23 cases (16.1%) (p<0.01). Conclusion. An individual approach must be taken for each patient, taking into account the goals and scope of the procedure. When performing surgery on two adjacent muscles, preference should be given to conjunctival access, and when working on one muscle, to limbal access. For operations of the reinforcing type, it is preferable to use limbal access, and for weakening operations, it is more advisable to conduct conjunctival access. In children of a younger age group and in patients with a history of allergic reactions, it is better to conduct operations with limbal access.
