DVD is a rare, poorly understood eye motility disorder of unknown etiology. In socially unacceptable deviation, surgical treatment is an option. We present patients operated with three different surgical methods. To evaluate and compare different surgical approaches for treatment of dissociated vertical deviation (DVD). Total amount of 20 patients with DVD of ≥ 20 PD are operated with three different techniques on superior rectus (SR) muscle: Group I with preoperative angle of 20-30 PD was operated with 8 mm recession of SR, Group II with preoperative angle of ≥ 30 PD undergo 3 mm recession with posterior fixation on SR and Group III with preoperative angle of ≥ 30 PD undergo-splitting of SR muscle. Surgeries for associated horizontal deviations were performed before surgery for DVD. Follow up was three years. In all cases amount of DVD deviation was significantly reduced. No binocularity was gained. Although hyperdeviation of affected eye was reduced in all patients, we didn't eliminate deviation completely. Despite smaller preoperative angle, residual angle was bigger (6-12 PD) in the patients in group I where only recession of SR was performed, compared to Group II and III where postoperative angle was 4-8 PD in both groups. There are no recommended guidelines for the surgical treatment of DVD and treatment is based more on the surgeon's experience than evidence based data. In our experience recession of the SR should be method of choice in the cases of smaller deviation. SR recession combined with posterior fixation suture and Y-splitting seems to be a safe and effective method for surgical treatment of unilateral DVD with bigger deviation angles. Y splitting with less surgical complications and increasing effect with time can be a good alternative to posterior fixation surgery.

Background: Congenital fibrosis of extraocular muscles ( CFEOM) is a group of genetically defined eye-moving disorders. The syndrome is clinically characterized by congenital non-progressive ophthalmoplegia caused by dysinervation of the cranial nerves with or without ptosis. As a main sign of a CFEOM, extraocular muscles get shrunken and fibrotic, which makes surgery more technically demanding and the result more unpredictable, which makes the treatment challenging and highly customized. Our paper presents variations of the clinical picture and treatment cases of CFEOM1. Objective: To outline the importance of the clinical examination with the exact measurement of deviations for the patients with ocular fibrosis and passive duction test under general anesthesia, establishing them as the main criteria for treatment. Methods: We treated seven patients (14 eyes) with CFEOM1. The decision of the treatment was based on the measurement of the eye position in the primary position (PP), the severity of compensatory head position (CHP), restriction of motility, and passive motility test performed before surgery in general anesthesia. In 3 cases, patients were treated conservatively with the treatment of refractive error and amblyopia. However, in 4 patients, CHP and position of the eyes in PP were not acceptable, motility was severely impaired, and patients underwent surgery. The first surgery was performed on eye muscles: recession of inferior rectus muscle (IRM), anteposition, and resection of superior rectus muscle (SRM). As a second step procedure, ptosis surgery was performed. When the muscle was too tight, and it wasn’t possible to have a satisfying result with conventional surgery, we used a tissue expander to improve the position and motility of the affected eyes. Results: In all operated cases, CHP has significantly improved and the position of the eyes in PP. Conclusion: Exact eye and head position measurements and a passive motility test during general anesthesia should guide the surgery. In the case when conventional surgery is not possible, implantation of a bovine pericard is a safe and effective method.

Background and Objectives: Predicting postoperative refractive development after paediatric intraocular lens (IOL) implantation remains challenging due to continued ocular growth and interindividual variability. This scoping review maps current evidence on demographic, biometric, and surgical factors influencing postoperative myopic shift in children undergoing cataract surgery with IOL implantation. Methods and Materials: A systematic literature search was conducted in PubMed and Scopus from the last ten years through October 2025. Eligible studies included children (≤18 years) with congenital or developmental cataract undergoing primary or secondary IOL implantation that reported postoperative refractive change and its predictors. Titles, abstracts, and full texts were screened according to PRISMA-ScR guidelines. Data were charted on study design, age at surgery, follow-up duration, refractive and biometric outcomes, and associated predictors. Results: Twelve studies met the inclusion criteria. Younger age at surgery, shorter preoperative axial length, and unilateral cataract consistently predicted greater postoperative myopic shift. Reported myopic change ranged from approximately −1.8 D after 2 years to −11.6 D after 15 years of follow-up, correlating with the rate of axial elongation. Optical biometry and modern formulas (e.g., Holladay 1) showed lower absolute prediction error than manual A-scan or SRK-II calculations. Postoperative complications, especially glaucoma and visual axis opacification, were associated with greater refractive change. Conclusions: Postoperative myopic shift is a predictable, age-dependent feature of paediatric pseudophakia driven primarily by ocular growth dynamics. Standardised biometry, age-stratified refractive targeting, and integration of longitudinal growth models into IOL calculation algorithms may improve refractive predictability and visual outcomes in children.
