Dissociated optic nerve fiber layer in a case of Terson syndrome.

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.
