Management of restrictive strabismus

Aim of the study This study aimed to target a special type of strabismus, the restrictive type, with prediction of its problems, diagnostic, management, and results. Patients and methods This is a prospective randomized study performed in Alexandria. The participants of this study were 42 patients having restricted strabismus, with different diagnostic criteria, such as abnormal ocular deviation with the movement of the globe defective and not reaching the midline, abnormal position of the head, forced duction test, and anatomical changes found during surgery. Results The cases of restrictive strabismus included congenital cases including monocular elevation deficit, Brown’s syndrome, congenital fibrosis of extraocular muscles, oculomotor nerve palsy, and long-standing strabismus, especially unilateral presenting in old age. Cases needed specific diagnostic procedure such as forced duction test to be performed preoperatively and intraoperatively, and postoperative results were satisfactory in most cases except cases that underwent previous surgery with muscle resection, aggravating the condition and leading to more restrictions. Conclusion Cases of restrictive strabismus, when properly diagnosed, with special considerations, could arrive at a postoperative satisfactory outcome
