OUTCOME OF SURGICAL TREATMENT IN CASES OF DISSOCIATED VERTICAL DEVIATION NOT ASSOCIATED WITH OBLIQUE MUSCLES DYSFUNCTION

Purpose: To evaluate the outcome of three surgical interventions: Bilateral superior rectus (SR) recession, bilateral SR Faden surgery, bilateral SR recession with Faden surgery in management of dissociated vertical deviation (DVD) not associated with oblique muscles dysfunction. Patients and Methods: This study includes 30 patients with comitant dissociated vertical deviation, they attended Mansoura Ophthalmic center for surgical management of their ocular deviation. They were divided into 3 groups according to procedure of the management. 10 patients were operated by bilateral superior rectus recession with Faden procedure (BSRRf), 10 patients operated by bilateral superior rectus recession only (BSRR), and 10 patients were operated by bilateral superior rectus Faden procedure only (BSRF). The results were compared. The patients were followed for 6 months postoperative. Results: Orthotropia were obtained in 9 cases of (BSRRf) group, while it was obtained only in 4 cases of (BSRR) and 2 cases of (BSRf) became orthotropic. Conclusion: Bilateral superior rectus recession with Faden (BSRRf) is more effective than bilateral superior rectus recession (BSRR) and bilateral Faden (BSRF) in cases of DVD.
