Purpose:
To report a case of paracentral acute middle maculopathy in a patient with high-flow carotid cavernous fistula.
Methods:
A case report of a 53-year-old male patient who sustained an iatrogenic high-flow carotid cavernous fistula and secondary paracentral acute middle maculopathy.
Results:
At review 1-week postembolization of the carotid cavernous fistula, there was no significant improvement in visual acuity, tests of optic nerve function, external ophthalmoplegia, and ptosis. Spectral domain optical coherence tomography was performed, which revealed hyperreflectivity of the parafoveal plexiform layers of the right eye with ill-defined margins straddling the inner nuclear layer.
Conclusion:
We suggest that spectral domain optical coherence tomography be performed in cases of high-flow direct carotid cavernous fistula where the best-corrected visual acuity is reduced out of keeping with other ophthalmic manifestations.
