Aims: To compare the clinical features and surgical outcomes of paediatric retinal detachment (RD) in high myopia and extreme myopia.
Methods: The clinical charts of 107 children who experienced RD and had a spherical equivalent (SE) of at least 6.00 dioptres (D) were reviewed. The patients were separated into a high myopia group (SE −6.0 to −10.0 D) and extreme myopia group (SE >−10.0 D). RD characteristics and outcomes were compared between these two groups.
Results: There were significant differences between the two groups in total RD (p<0.001), the presence of posterior staphyloma (p<0.001) and some types of breaks. More eyes in the extreme myopia group required vitrectomy after the initial RD repair. In the high myopia group, retinal reattachment was achieved in 79 eyes (97.5%) at the end of the intervention, whereas in the extreme myopia group, retinal reattachment was achieved in 22 eyes (73.3%). Multiple logistic regression showed that a higher refractive error was the only negative predictor of surgical outcome (p = 0.026).
Conclusion: Due to differences in aetiologies, clinical characteristics, required surgical procedure after initial repair, surgical and functional outcomes, paediatric RD with extreme myopia should be addressed differently from paediatric RD with high myopia.
