Abstract

Purpose: To show that diffuse unilateral subacute neuroretinitis (DUSN) may masquerade as multiple evanescent white dot syndrome, and to describe structural and functional recovery following treatment in DUSN.

Design: Case report.

Methods: Baseline and serial optical coherence tomography (OCT) and perimetry following photocoagulation of nematode.

Results: After laser treatment, the inner segment-outer segment (IS–OS) junction was restored and the visual field was improved.

Conclusions: DUSN, early on, can be mistaken for other inflammatory white dot syndromes. OCT and perimetry, in combination, provide strong support for success of treatment with photocoagulation.

Keywords::

• DUSN
