Acquired Brown Syndrome After Retinal Detachment Surgery

ABSTRACT

PURPOSE: To report a case of acquired Brown syndrome found in the left eye of a female patient who had undergone surgery for proliferative vitreoretinopathy. METHODS: A 41-year-old female patient presented with right hypertropia and esotropia. We reviewed her history, conducted an ophthalmic examination and performed surgery. RESULTS: Prior to presentation, the patient experienced a sudden decrease in visual acuity. She was diagnosed with proliferative vitreoretinopathy caused by rhegmatogenous retinal detachment, and underwent scleral buckling. After surgery, with the eye in the primary position, the right hypertropia was 9 prism diopters and the esotropia was 30 prism diopters. The patient was unable to elevate the eye in the adducted position. A forced duction test was performed and we detected a restricted elevation in adduction. By performing a tenectomy of the superior oblique muscle and a recession of the medial rectus muscle, orthophoria was obtained in the primary position, and the elevation in adduction improved. CONCLUSIONS: Herein, we report satisfactory results of a procedure in one case of acquired Brown syndrome following retinal detachment surgery.
