Myelin Fiber Syndrome, Strabismus and Amblyopia: About A Case

Abstract

We report the case of a 2.5-year-old female patient referred for exotropia of the left eye evolving since birth. He had no particular history. Refraction under cycloplegics found strong anisometropia with strong myopia of the left eye: -1.50 (-1.00 to 100°) in the DO and -16.25 (-1.25 to 50°) in the OG. Corrected visual acuity was unquantifiable given the child's age. Anterior segmen examination was normal as well as ocular tone. Fundus examination showed diffuse chorioretinal atrophy in the posterior pole of the left eye, peripapillary myelin fibers and a normal macula. The fundus examination of the right eye was normal The clinical picture and the imagery together lead us to suggest a myelin fiber - myopia - amblyopia syndrome. The patient was put on amblyopia treatment with regular follow-up, with no notable improvement to date1.
