We investigated the case of a young man with blurred vision in his left eye. His visual acuity was slightly decreased, and ophthalmoscopy disclosed a gray-white lesion in the macula. He had no systemic or ocular history. On the visual field test, the threshold sensitivity was decreased in the corresponding region. Spectral domain optical coherence tomography (OCT) demonstrated a disruption in the photoreceptor inner and outer segment (IS/OS) junction and undulation of the retinal pigment epithelium (RPE) with backscattering. We re-examined the patient after two weeks and after three months without any treatment. Visual acuity and visual field results were gradually normalized, and OCT demonstrated the recovery of continuity in the photoreceptor IS/OS junction, as well as decreased RPE irregularity with minimal backscattering. We used spectral domain OCT instead of time domain OCT (OCT3) so that we could provide better image resolution of the acute retinal pigment epitheliitis (ARPE). Finally, we observed recovery of the functional and anatomical changes in the ARPE patient with a resolution of the condition within three months following the initial examination, using OCT and visual field tests.

Purpose. To report B-scan and "En-face" spectral-domain optical coherence tomography (SD-OCT) findings in acute retinal pigment epitheliitis (ARPE). Methods. Two patients (3 eyes) with ARPE were examined. Fluorescein and indocyanine green (ICGA) angiography, B-scan, and "En-face" SD-OCT were performed in each patient at initial and follow-up visits. Results. Both patients presented with acute onset of blurred vision, and one with bilateral involvement. B-can OCT revealed disruption of the macular retinal pigment epithelial (RPE) inner band layer and photoreceptors' inner and outer segment (IS-OS) junction. Hyperreflective dots were observed in the outer nuclear layer (ONL) above the RPE/IS-OS disruption. Just around these hyperreflective dots, slight thickening of the hyperreflective IS/OS junction was observed. During the late phase, indocyanine green angiography (ICGA) showed a macular cockade-like hyperfluorescent halo. "En-face" OCT showed the same cockade-like appearance with a hyporeflective center and a hyperreflective border matching the pattern observed on ICGA. At followup, as vision improved without treatment, B-scan OCT demonstrated progressive resolution of the hyperreflective and disrupted lesions; "en-face" OCT also showed disappearance of the macular cockade-like halo with a transient discrete hyperreflective macular star at the RPE level in one eye. Conclusion. "En-face" OCT associated with B-scan SD-OCT analysis appears to be very helpful in the diagnosis and followup of ARPE. The pathophysiology of ARPE remains complex and still poorly understood. These techniques help define the location and extent of structural damage occurring in this disease.
