| 본문 : Spontaneous regression of retinal whitening (axoplasmic stasis) or myelinated nerve fiber layer (MRNF) are rarely reported. Regression of peripapillary MRNF has been reported in eyes with ocular events, such as chronic papilledema, advanced glaucoma and choroidal melanoma after plaque radiotherapy. Here, we report an interesting case of sequential regression of axoplasmic stasis after pars plana vitrectomy with epiretinal membrane peeling.
A 70-year-old man with a complaint of metamorphopsia and a visual acuity of 20/50 in his right eye was diagnosed with epiretinal membrane (ERM), with an incidental finding of myelinated retinal nerve fibers (MRNF) along the inferotemporal vascular arcade. The patient underwent 25-gauge pars plana vitrectomy with ERM peeling, irrelevant to the area of the retinal whitening. One month post-operatively, subtle decrease in the intensity of the myelinated retinal nerve fibers was noticed. After 3 months, definite regression of the myelinated retinal nerve fibers occurred with aggregated patchy appearance on the optical coherence tomography (OCT) scan. Total regression appeared at 6 months postoperatively, both on fundus and OCT exam. His best corrected visual acuity was 20/25. This sequential depiction of regression may be of interest in understanding the pathophysiology of axoplasmic stasis. |
