Dissociated optic nerve fiber layer in a case of Terson syndrome

Abstract

Purpose: To report a case of Terson syndrome who developed dissociated optic nerve fiber layer appearance after pars plana vitrectomy. Case report: The author reports a young male patient with Terson syndrome who developed bilateral vitreous hemorrhage and sub-internal limiting membrane hemorrhage after road traffic accident. He underwent pars plana vitrectomy and removal of the already detached internal limiting membrane and the sub-internal limiting membrane hemorrhage in both eyes. In both eyes, dissociated optic nerve fiber layer was appreciated and left eye had a peculiar resemblance to the appearance of cystoid macular edema. Conclusions: Dissociated optic nerve fiber layer appearance may be noted following vitrectomy and removal of detached internal limiting membrane in patients with vitreous hemorrhage and sub-internal limiting membrane bleed due to Terson syndrome.
