简要总结
The goal of this clinical trial is to compare the results of two surgical modalities in patients with Dissociated vertical deviation with inferior oblique muscle overaction . The main questions it aims to answer are:
- How much does the magnitude of DVD improve after each modality?
- Is the IOOA eliminated? Participants will be divided into two equal groups; Researchers will compare the efficacy of symmetrical anteriorization of the inferior oblique and adding an additional rescetion to one eye in the second group to see which group had more signifcant reduction in the magnitude of DVD and IOOA.
详细描述
A prospective study was performed on patients with bilateral symmterical dissociated vertical deviation(DVD) and bilateral inferior oblique muscle overaction (IOOA) in Cairo University hospitals starting from February 2018 through December 2021. Patients wetre included in the study if they had a minimum follow up period of 6 months. The study included 54 patients (108 eyes) with manifest DVD and IOOA in boths eyes. Patients were divided into two equal groups. The paitents in group 1 underwent symmetrical inferior oblique muscle anteriorization, while the patients in group 2 underwent ayymmetrical surgery , where inferior oblique anteriorization was performed in one eye the same manner is in group 1, and the eye with the larger deviation had an additional 3-5 mm rescetion of the inferior oblique muscle along with anteriorization according to the measured DVD difference between both eyes, whether less than or more than 5 prism diopters respectively.
