Spectral domain optical coherence tomography findings in acute retinal pigment epitheliitis.

Objective: To report spectral domain optical coherence tomography (SD-OCT) findings in 3 patients with acute retinal pigment epitheliitis (ARPE).

Methods: Retrospective chart review. Methods: Charts of three young patients with ARPE were reviewed.

Results: In acute stage, SD-OCT demonstrated abnormal hyperreflectivity involving the photoreceptor outer segment layer and hyporeflectivity involving the associated RPE layer in all cases. In chronic stage, SD-OCT showed decreased abnormal reflectivity. In one case with incomplete recovery of visual acuity, disruption of the photoreceptor inner and outer segment (IS/OS) junction was demonstrated in chronic phase.

Conclusions: SD-OCT confirmed that the outer segments of foveal photoreceptors and the associated RPE layer were the primary affected sites with ARPE. Detection of integrity of the foveal IS/OS line in resolved ARPE could be helpful in prediction of visual prognosis.
