Aim. To substantiate the recommendations on the tactics of recurrent operations for strabismus in children on the basis of histological investigation of the fragments of «weakened» muscles. Methods. Conducted was a retrospective analysis of recurrent surgical treatment of 2 patients with concomitant convergent strabismus. In order to determine the cause of dysfunction of the muscles conducted was a histological study of 80 fragments of the lateral rectus muscles, which were excised during surgical treatment of convergent strabismus. Results. Muscle fibers were found only in the distal sections during the resection of the lateral rectus muscles at a distance of 8.5-9 mm. Taking into consideration the fact that at point were the muscle transitions into the tendon located are the palisade nerve endings, which may play the major role in the contraction process, the exceedence of the above mentioned amount of muscle resection during strabismus surgery is dangerous, since it can lead to the disruption of the eye mobility. Conclusion. During recurrent operations for strabismus correction it is recommended to use major recessions of the «strong» muscles, and for ease of muscle fixation at a great distance from the attachment point - the technique of the «sliding noose».

Purpose. Тo analyze clinical efficacy of the surgical treatment of previously operated strabismus using limbal incisions which are lengthening the conjunctiva and Tenon's capsule. Material and methods. The study included 440 patients (440 eyes) with previously operated strabismus at the age of 4 to 68 years old. The main group included 240 patients (240 eyes) who underwent strabismus surgery by limbal approach; the control group included 200 patients (200 eyes) who underwent surgery by paralimbal conjunctival approach. Horizontal strabismus occurred in 146 patients (60,8%) in the main group and in 158 (79%) in the control group. Horizontal strabismus in combination with vertical strabismus was found in 94 patients (39.2%) in the main group and in 42 patients (21%) in the control group respectively. The following approaches were applied: Y-shaped limbal approach, T-shaped incision of the conjunctiva, lower limbal peritomy, circular limbal approach with an additional horizontal incision towards the muscle being strengthened. Results. Good cosmetic result in the main group was achieved in 94.7% of cases, in the control group in 87% of cases, р<0.001. Re-surgery in the long term period was required for 39 patients (19.5%) in the control group and 14 patients (7%) in the main group, р<0.001. Conclusion. Limbal approaches performed to lengthening the conjunctiva and Tenon's capsule on the side of the weakened muscle and shortening on the side of the muscle being strengthened, are enhancing the effect of recession and resection, thereby contributing to the achievement of the state of orthotropy in 83% and have a good cosmetic result in 94.67% of cases. Key words: limbal conjunctival approaches, limbal conjunctival incisions, strabismus, children.

Purpose: To determine the possible predictors of the motor outcome after corrective surgery for acquired comitant esotropia. Methods: The study included 40 patients with acquired comitant esotropia. After evaluation of the visual, sensory, and motor status; cycloplegic refraction; fundus examination; and spectacle prescription, all patients underwent corrective strabismus surgery. A successful motor outcome was defined as 0 to 10 prism diopters of horizontal tropia. Statistical analysis of the results was done using the chi-square tests. Results: At the sixth postoperative month, 90% achieved a successful motor outcome, while 2.5% had a consecutive exotropia >10 prism diopters, and 7.5% had a residual esotropia >10 prism diopters. A statistically significant relationship existed between the motor outcome and the following: preoperative results of the Worth four-dot test at 6 m ( p = .011) and 0.33 m ( p = .009), preoperative distant ( p = .016) and near ( p = .017) angles of esotropia with glasses, postoperative near angles of deviation at 1 week ( p = .005), 1 month ( p < .001), 6 weeks ( p < .001), 3 months ( p = .001), and 6 months ( p < .001) following surgery, postoperative distant angles of deviation at 6 weeks ( p < .001) and 3 months ( p = .03) following surgery, 6 week ( p  = .01) and 6 month ( p  = .036) postoperative results of the Worth four-dot test at 0.33 m, and the 6-month postoperative sensory outcome ( p  = .006). Conclusion: Preoperative and postoperative sensory and motor functions are predictors of the 6-month postoperative motor outcome.

Abstract Purpose The purpose of this study was to determine the surgical outcome, dose-effect (DE), and degree of binocularity in patients undergoing surgery for consecutive exotropia following initial surgery of esotropia. Patients/Methods Twenty-one patients were identified. We analyzed the mean angle of deviation pre- and postoperatively as measured with the alternate prism cover test, DE, and binocularity. Results All patients had had previous strabismus surgery. The surgery for consecutive exotropia had been performed at a mean age of 35.92 ± 18.26 years. In 19 of these patients, surgery of consecutive exotropia involved at least one previously operated extraocular muscle, and the mean interval to the previous surgery was 25.67 ± 16.14 years. The mean angle of deviation (DE) at distance and in the primary position was − 33.43 ± 12.75 prism diopters (PD) preoperatively, + 0.76 ± 7.91 PD 1 week after surgery, and − 7.24 ± 12.14 PD 3 months after surgery. The mean DE was 3.58 ± 1.53 mm/PD at 1 week and 2.70 ± 1.78 mm/PD at 3 months post-surgery. Postoperatively, 62% patients had a binocularity of at least Bagolini positive, 33% had either a positive TNO or Titmus Test, and 24% were Lang I positive (550″). Conclusion Performing strabismus surgery with consecutive exotropia results in restoration of some binocularity in a large number of patients, even in adults, and should be considered as a possibility. The dose-effect is comparable to conventional surgery of exotropia.

Purpose: To compare the different surgical methods performed on a single eye in a single session and the factors that affect the success of patients having consecutive exotropia (XT) developed after esotropia surgery. Methods: The medical data of the patients who underwent surgery for consecutive XT were reviewed retrospectively. Patients with followed of 6 months or more were divided into four groups; patients with medial rectus (MR) advancement (Group 1 = 10), MR advancement and MR resection (Group 2 = 12), MR advancement and lateral rectus (LR) recession (Group 3 = 13), MR advancement, MR resection, and LR recession (Group 4 = 14). Success results and possible risk factors were investigated. Results: Forty-nine patients with consecutive XT (21 female, 28 male) were enrolled in the study. The mean age of overall patients was 22.97 years at surgery for consecutive XT. The groups did not display significant differences in terms of surgery ages, gender, refraction values, visual acuity, amblyopia, inferior oblique overaction, limitation of adduction, surgical success rates, and follow-up time ( p > 0.05). Patients of Group 4 had larger preoperative and postoperative deviation, while Group 1 had smaller ( p < 0.05). The surgical success rates of Groups 1, 2, 3, 4 were 90%, 75%, 76.9%, and 50%, respectively ( p = 0.192). Statistically, no factor was found to be effective in surgical success rates ( p > 0.05). Conclusion: Surgical treatment of consecutive XT is successful in most of the patients with numerous surgical options performed on a single eye in a single session. Patients, particularly with a high amount of deviation should be warned about the possibility of additional surgery.
