Simultaneous Presentation of Duane Retraction Syndrome and Coatsʹ Disease: A Case Report

-

Introduction: Duane retraction syndrome and Coatsʹ disease are two relatively rare ocular conditions that occur in congenital and acquired forms in children. We present a 12-year-old boy with the chief complaint of eye deviation who was diagnosed later on to have Duane retraction syndrome in one eye and Coatsʹ disease in the other. After a comprehensive review of literature, we assume that this is the first case of simultaneous presentation of these two disorders ever to be published. However, we do believe that these are two separated entities and their simultaneous presentation in this patient is pure coincident. Case:A twelve-year-old Asian male was presented with about 25 prism diopters of exotropia in primary position, limited abduction/adduction, and narrowing of palpebral fissure of the right eye since childhood. The left eye showed lipid deposition, macular edema, and peripheral retinal telangiectasia. Conclusion: The occurrence of two different congenital and acquired ocular diseases is rare. This is the first simultaneous presentation of Duane syndrome and Coatsʹ disease ever to be reported in a young patient.
