“…This means that a low degree of anisometropia is associated with better visual outcomes after the prescription of cycloplegic refraction findings and intensive occlusion therapy [ 4 ]. Strabismus in Straatsma syndrome is another factor associated with poor visual prognosis [ 4 , 7 ]. In both, our patient's initial BCVA was 0.1, with a high degree of anisometropia and similar spherical equivalents.…”

The aim of this article is to report two cases of Straatsma syndrome, a rare disease characterized by the traditional triad of unilateral myelinated retinal nerve fibres, axial myopia, and amblyopia.The cases were a five-year-old and a three-year-old girl, both with unilateral myopia, visual acuity of 0.1 (decimal), and myelinated retinal nerve fibres in fundoscopy. Prescription of cycloplegic refraction findings and occlusion of the involved eye was attempted in both cases, but visual acuity did not improve. Poorprognostic factors of Straatsma syndrome include a high degree of anisometropia and extensive myelination.

“…Changes in peripheral retina of myopic are predisposing factors for retinal detachment and include lattice degeneration, white-without-pressure, pigmentary degenerations, and retinal tears and holes. Association of extensive myelinated nerve fibers and high degree myopia have been reported [16]. Ellis et al [17] found that 83% of patients with myelinated retinal nerve fibers had myopia greater than 6 diopters.…”

Background: Myelinated retinal nerve fibers (MRNFs) are usually unilateral and asymptomatic benign lesions associated with mild hypermetropia, emmetropia, or severe myopia. We describe herein an myopic patient with a syndrome of ipsilateral myelinated retinal nerve fibers associated with other pathological changes: epiretinal membrane with pseudohole, vitreomacular traction syndrome and bilateral lattice degeneration.Methods: Extended ophthalmoscopy was used to evaluate retinal posterior segment. Infrared reflectance imaging helped in visualizing sub-retinal pathology. Detailed images from within the retina were obtained by using optical coherence tomography.Results: Ophthalmologic examination revealed ipsilateral small temporal myopic conus with lattice degeneration temporally and inferotemporally. The area of myelinated nerve fiber extended into the pappilomacular bundle, but did not reach the fovea. At the fovea, an epiretinal membrane with clinically visible vitreomacular traction and some retinal elevation was found. In the peripheral fundus areas of lattice degeneration temporally and inferiorly was also noted. The OCT scans of the affected eye showed an incomplete posterior vitreous detachment with traction of a thickened posterior hyaloid base to the fovea. There was distortion of the foveal anatomy with a small amount of subfoveal fluid but a full-thickness macular hole could not be detected. Macular traction detachment of retina and epiretinal membrane with macular hole were treated surgically (S/P Repair Complex RD (25g, 20% SF6, membrane peel with gas endotamponade) and vitreomacular traction was released. Lattice degeneration was treated by laser (S/P Laser).Conclusions: MRNF lesions were stable and although associated with other ocular pathology progression was not observed during follow-up.

“…Extensive unilateral myelination of nerve fibers can be associated with high myopia and severe amblyopia, which unlike other forms of amblyopia is notoriously refractory to treatment. [ 5 ] In such patients, myelination surrounds most of the circumference of the disc.…”
